Its here! Alex and Vic (my One Lap partners in crime) dropped it off last night. I have to put on 800 more break-in miles, which is pretty tough given the fun-factor of this thing.

To be the fastest BMW at One Lap, we have to beat a new factory entry M3 driven by Mike Renner - a BMW Performance Center instructor. I am pretty happy with the choice of weapon!

The car goes on the lift tomorrow to figure out our direction on a few things, but we already have most of it lined up with some help from our friends at Actice Autowerke, Diffsonline, JRZ, and Performance Friction with more to come. The goal is to drop at least 200# while keeping it nice and clean, get it on a performance suspension (JRZ RS DA dampers!), and pep it up a little in the motivation department.

PS - go ahead - knock my photo skills...

You suck at teh piczurs.

Aren't you supposed a break a car in like you stole it? Red line that biach!

Ass. Yes - that is certainly my philosophy past a little initial engine work, but BMW has other thoughts and since ECUs are now smart enough to record data...

So how's the fun factor compare to the 335i or anything else?

And since you asked, yeah you suck at pikchas.

I am betting it is more fun than the 335, but I haven't really unleashed on it yet like I have a 335 (break-in...). It definitely feels a little smaller and nimble around town - we will see how it plays out with more load shortly.

At least I can spell :D

When the prices come down on the 1 series chassis, they are going to make some great club race cars! Is the front suspension multi-link?

Awesome! Cant wait to see it done!

Very cool! The only problem I have with it is the Fake-O LSD diff. For $36K you should get a real LSD.

I'm eager to see how this turns out... I've been considering a 135i as a DD.

Here are few few quick shots (cell phone) of the brakes on the 135i, as I PDI'd a few of 'em a week or so ago. To answer the front suspension question: yes they are multi link front suspension & rear 5-link (like E90's but with 10mm wider hubs).

It's pretty much an E90 with a smaller body.

FWIW, those brakes are nice, yes, but I am betting a proper set of PFC Z-Rated monoblocs will lop off over 10# per corner...

Look - spelling and grammar I can do, typing is hit and miss, and photography is often miss. Luckily I don't live in a cyber world and have some additional life skills :)

So what do we think the target weight can be for a 135 Mod style racecar, under 2200?

Will any of the 120d widebody body parts fit? Any chassis parts carry over :)

This is going to be awesome James, can not wait for a nice update

So what do we think the target weight can be for a 135 Mod style racecar, under 2200?


That would be pretty impressive given the car weighs nearly 3400 lbs from the factory. Look at the lengths Phil is going to in an effort to get a 3000lb factory weight E36 M3 down to hopefully ~2100.

Still, I think with some turbo tuning, you can give the 3700 lb M3 (oink, oink) a run for the money.

That said, I'll take either ;-)

I thought the 1 series was more closely related to the e46 chassis, since the 1 series came out in '04.

No, pretty much E90. Those came out only a year later.

Less typing... More pictures!!!

I wonder if the 135 is built overly beefy to compensate for its small size though. Thats where i think weight could be loss. Its physically a smaller car, so by the nature of its overall size, it should be able to be pretty light...might require a lot of work, but i think it has such crazy potential.

What I had read is that some of the relatively high weight for the size is due to the fact they used std steel rather than the high-carbon steel they use in places on the E90 in order to keep the cost down.

I agree in the potential though...

It's a club racer for sure.. That weight is troubling, but I think that's the direction with most production cars...

James, it's too bad you're going to this much trouble to only finish behind of couple of autocrossers in a 10 year old M Coupe.

LOL. He's going to plug your intake with pomade for that.

I know a couple of guys like that...

I think it will be a little pocket rocket, but will lack some of the stability that comes with size. This means a ton of fun on the track, but ultimately a modded E92 M3 racecar would kill it. That is NOT to say that for less money, you couldn't make the 1 faster and extremely fun.

I resemble that remark! I figure that you and Marc will be doing alot of farming in that overweight beast, so Woody and I can focus our attention on "Team Testosterone's" 135i.

BTW, their back seat will be even tighter since word has it they'll be bringing along a sheep to keep Vic company.

Neil

Looks like a great project. The factory 6 pistons calipers are pretty heavy one these. A caliper that is more "race spec" built would be better for sure. I think we can get the 135i without a sunroof here in canada, just like we didn't have it on the Z3 M coupe.

Lol, definitely not me, i lack the extra beef :stickoutt

Pocket rocket for sure...think Exige :) Just need to get the car 1000# lighter :devillook

280 slicks on all 4 corners, 400hp, lots of aero, should be good to go.

For the $30k+ saved on the E92 M3 (probably a lot more considering engine stuff) the 135 is the future of mod class domination IMO. Look at whats being done with E30's right now, pretty much says it right there. Will still come down to driver talent though, even with the HP.

Okay, fine, 400+ hp, which makes the 360 hp M Coupe a non-factor.

Does that also mean Vic is NOT allowed to drive it?

I think there's way too much hype around this car. The car is marginally lighter than a 335, marginally smaller than a 335, the same height as a 335, and yet people are hailing this is as the "future of mod class domination." Doesnt the size of the 335 help it, and the price difference between a 135 and 335 is laughable, especially when you consider the fact you can buy an 07 335 when compared with an 08 135.

Vic (that's me) is flying to Mid-America to learn how to drive in the Midwest. I'm what you call a "specialist." So contrary to popular opinion I will be driving the sh1t out of this poor car.

It will be nuts. Lock up your women and horses (or sheep), and do NOT leave your tires sitting out.

That probably depends on whether or not the cameras catch any Orlando I4-like shennanigans from you. ;)

Weight reduction time...

http://www.bimmerworld.com/images/135/frotor.jpg

Blows me away. Without even touching that heavy caliper, we pulled 10 pounds out of each front corner with the PFC rotor. Looks like the standard E90 fitment parts are going to work, but we are tweaking tomorrow. This of course means that anyone that wants to add a lot of weight to the front of their single-piston E90 car can swap these anchors on.

Add another 10# per caliper, plus 10# per wheel/tire all 4 corners and the tally is up to 80 streetable pounds!

That probably depends on whether or not the cameras catch any Orlando I4-like shennanigans from you. ;)

Doesn't ring a bell...

Wheel/tire/brake time...

Rear: Looks like a lot will fit. I am betting even a 285/295 with aggressive rolling and a really low et - that part is hard to find though. This 18x9 BBS RE has plenty of inner clearance.

http://www.bimmerworld.com/images/135/rbbsre_s.jpg

Rear brakes - for now we just added rear brakelines, working on pads and other stuff...

http://www.bimmerworld.com/images/135/rbrakeline_s.jpg

Not surprised, the E90 fits 280's no prob too.

Front - this is where the magic happens. Rotors drop 10# per corner, calipers another 8# per corner. 36 pounds of unspring mass in the brakes alone! Installed the PFC Z28 monoblocs while we wait for the Z-Rated kit to arrive.

Some of the weight savings is from the bolts...

No - we had to put studs on. And while thsoe wheels are sweet, a 255 is simply not going to get it done up front with the level of modification we want to do on a new car (read no paintwork). Thinking 235/265 or similar...

Hi James... It's possible 255's will fit up front. My setup is 17x9 Ltw5's with 255 Neovas and 3mm spacer up front. Backs have room for more. I wonder if with the suspension changes you might be planning, that it won't be possible, but this works with a H&R Sport lowered 135i, with about -2 deg camber.

Interesting... That is very roughly the same setup we tried, but with an 18x9BBS, 45et, 5mm spacer. That should give us effectively a 40et versus your 38. We very likgtly touched on the inside, due likely to what appears to be more rim protector on the Hankooks I had mounted on those. It looked like there was no way as we lowered the car without some body work that the fender was going to cover that setup. We will be adding more camber at the top to pull the tire in, but it looked REALLY off. Certainly a 255/285(?) would be fun...

Also though, Michelin PS2s that we will likely be running for OLOA are available in 235 in a little stickier compound - not sure how that compares to a wider tire.

Yeah, a 285 is definitely possible in back, but you'd need more offset. My ET41 9" wide wheels bring that 255 right out to the fender. No rubbing at all, but there isn't room for more on the fender side. The Advan AD07s are a great tire too.. TR sells them too, as well as the RE01R's.

Now, I just have to wait for my first event in 3 weeks. The wait is killing me already. Btw, I'm definitely planning on coming up to see you guys when you come up to New Hampshire.

Tonight after a long drive to and from CMP for a Spec E30 enduro (woohoo!), I couldn't let the pile of Active parts sit any longer. Motivation struck - get the BOV kit in...

Stock stuff

http://www.bimmerworld.com/images/135/enginestock_s.jpg

Stock BOV

http://www.bimmerworld.com/images/135/BOVstock_s.jpg

And I start pulling parts. Went quite well and the kit was easy for a seldom shop worker to install. Until I dropped an air cap. Then a bolt. Both landed on that extra sweet plastic flatbottom new BMW cars have (would otherwise be on the ground easily retrievable.

http://www.bimmerworld.com/images/135/enginedis1_s.jpg

I wrap up the BOV install and am pretty proud of myself. It only took about 5 minutes to pull the main plastic undertray to get the things I dropped, so I am also motivated and start eyeing that intercooler kit that I had planned to push off on the guys.

http://www.bimmerworld.com/images/135/bovaa_s.jpg

After a quick start and rev of the engine to hear the new blowoff, I am way too impressed with my work and decide to start project 2.

http://www.bimmerworld.com/images/135/enginedis2_s.jpg

OK - I realize that the minor modification I had been planning is a little less minor and not having touched a front end in years, I start to worry a little. I putz around the office for a bit and then decide to get in and do it right - which means removing more parts so I can really get a good look at the situation. Psychologists call this first stage denial.

http://www.bimmerworld.com/images/135/enginedis3_s.jpg

I am going to gloss over this part. Anger - I am an idiot - getting popped in the jaw with an airhose rams this home. I am now wondering if I will get it back together again. Too deep to back out and I am really wishing I had left it in the shop while I was out and come back to a completed install. Bargaining - I call Marks, our shop manager and crew chief to see, umm, if he was planning to drop by the shop on Sunday for anything maybe? He knows not to answer this call. I think about leaving it in the floor and seeing if this will magically happen, even though I am the one that took it apart and likely the only one that can "easily" ID all the parts. The depression stage plants me at my desk procrastinating and whining internally. I decided to go home, was ready to walk out the door, but I need a little more time to think, so I stick around. Finally - acceptance. I put on my big-boy pants and grab the airsaw and go to town.

http://www.bimmerworld.com/images/135/intercooler1_s.jpg

Everything is coming together nicely now actually - still have to put it back together though. The intercooler plumbing goes on nicely and I get that puppy bolted in place.

http://www.bimmerworld.com/images/135/intercoolermounted2_s.jpg

Somehow I kept fairly good mental notes and things go back together relatively uneventfully!

http://www.bimmerworld.com/images/135/enginetogether_s.jpg

I even get the headlight washers going again without losing much fluid. And the crowning achievement - no extra bolts left over!!!

http://www.bimmerworld.com/images/135/powerdone_s.jpg

Again, I am motivated by the result, but this one took a little longer, so not that motivated. I look at the AA Programmer on my desk that I have been playing with in my procrastination stage. I am an EE type - why not. And to cap the night, I get it in the car in about 30 minutes and it starts!

Suspension will be installed next week while I am gone, then we do exhaust, make a final choice on wheels and tires, toss in the limited slip diff, and we are pretty much ready for testing.

At least you will have the technique down pat by the time you do all of that to mine.

Not yet - those were a test fit only.

Geordie - Know anything about the N2/N3 compounds? Wondering if a 235 in those would be better than a std 245. Hoping to fit a 255, which I think is the best answer - need to get the front suspension on in final form first though...

This has been an on-going question for as long as I can remember and I can tell you that I've had a conversation with a rep from Michelin when 295/30/19 N1s were on backorder last year when a customer of mine wanted me to verify that standard PS2s on his 997 wouldn't screw anything up to which he responded that the compound is identical, and that the only difference is one has N1 on the side and one doesn't. Take that for what it's worth, but I've been doing that and vice-versa for years. Hell, I've got MO PS2s on my wagon right now!

It needs a big wing, spoiler, and widebody...but god damn, I think thats the future of club racing.

Screw Spec miata...Lets get a Spec 135 series!

In a couple year you'll be able to build a really clean simple 135 prepared car for under $50k, and be FAST.

LMFAO, James. You've been corrupted by Arrive and Drive. (Next time put on the big boy pants before you go cutting things off a car.)

Not actually a requirement. You know, our first year of business we sold used parts from salvaged cars. There is a certain satisfaction in ripping something apart and knowing you don't have to put it back together. It is when you realize that you do indeed have to follow that last instruction - assembly is the reverse of removal, that all hell breaks loose.

The Advan AD07s are a great tire too.. TR sells them too,

I agree. The AD07 should be quite a bit faster than the PS2. A popular tire for OLOA.

I spoke with a Michelin engineer a couple months ago about the PS2 compounds. I don't know which is which, but the Z06, ZR-1, and Viper ACR all use different compounds which have been "tuned" to the cars. Those tires are all HUGE, though, so there probably wouldn't be availability in the sizes you're looking for.

The PS-2 is a fantastic tire (high grip in both dry and wet), but relatively soft in the sidewall. This makes them perfect for high-end sports coupes since most of their owners never take them off the public roads. But, for a 1-lapper, wouldn't something like an RE-01R be a little stiffer and stickier? What is the minimum treadwear rating for 1Lap?

I agree. The AD07 should be quite a bit faster than the PS2. A popular tire for OLOA.

That's what I'll be running at this year's One Lap. Tested the AD07s this past weekend at BeaveRun and was very impressed.

Neil, have you made a comparison with the RE-01-R's? I've been hearing about the Yokos, but haven't tried them. I'd be interested to hear your thoughts.

Not back-to-back. Ran the then brand new RE-01Rs in the 2006 One Lap. Recall them feeling like full tread RA-1s in the dry, but they were dreadful in the cold and wet at Putnam Park and Road America. Don't really know whether the AD07s will be any better in those conditions, but wanted to try something new.

BTW, I agree with previous posts that the PS2 is a terrific all-around tire. However, the AD07 and RE-01R are significantly faster, at least in the dry.

Neil

The AD07s are considered by many to be the best street tire out there. Many have tested them back to back against the RE-01R and found them to be superior. The 'stones tend to get greasy after long use in high temps.

However, the Yoks are much more expensive.

I would also look into the new Dunlop Z1 Star Spec. They are getting a lot of good reviews.

We've had exceptionally good results with the AD07 in the wet, even when shaved to 5/32". Each time we ran these in the wet on our STU classed M3 we compared extremely well vs. other competitive/fast/National Champions on R compounds. Sure, I'd rather have an R compound in just about any condition except deep standing water, but the AD07 is a lot closer in the wet to an R than in the dry. The AD07 is good for 1.15-1.20 g lateral and 1.1 g under braking in the dry, from data logging. The RE01R was about the same if not a tick better at peak, but with less feel.

Left: Shaved AD07 in 265/35/18 on 18x10. Note the low void ratio.
Right: 255/40/17 on 17x9.5" wheel - a great combination

As for the RE01R vs AD07 comparisons.... these two tire models are fairly different in many ways. We've tested on both models, in several sizes, in both RWD and AWD cars. The sidewall stiffness and overheating resistance go to the AD07, hands down. Not as sensitive to tire pressures or wheel width used. The AD07 tires tend to "run big" also, so check the "as measured" section and tread widths. Usually we see tread widths +10mm wider than marked. Pricier of the two, by far.

Left: Two sets of RE01Rs shaved to 5/32"....
Right: Hankook RS2 next to RE01R. Note the massive void ratio of the Hankook, at left.

The RE01R works better in colder ambient temps and has a slightly softer rubber compound. Some folks find the RE01R easier to drive, since they are a bit sloppier. It depends a lot on the sidewall height, and there are several different compounds on the RE01R, depending on tire size. Do a check on TireRack's spec page for this model and you'll see 140 thru 180 treadwear ratings for various sizes. Make sure to use as much wheel width as you can with these, and keep an eye on pressures and pyrometer temps - we spray them with water between runs whenever possible. The RE01R responds favorably to shaving, as they are molded with 10/32" of tread and have enough void to add some squirm. We always shave them to 5/32". For OLOA I dunno if I'd go that low, but I wouldn't run them full tread.

Both the AD07 and RE01R are leagues better than 99% of the other "extreme performance street tires" out there.

Good luck at OLOA guys...

The AD07 is good for 1.15-1.20 g lateral and 1.1 g under braking in the dry, from data logging.

That 1.15-1.2 can't be accurate, do you have the data to show the conditions? Sounds like it was instantaneous peak at speed, not constant (i.e. on skid pad).

Suspect you're right.

At dry skid pad event in last year's One Lap, top car (a Z06) pulled 1.074 g.

He was not pulling 1.15 sustained steady state...and 1.2 seems a bit low if it was an instantaneous lateral acceleration.

For comparison FSAE cars do 1.45-1.5 steady state on skid pad...shifter karts do 2-2.25.

That 1.15-1.2 can't be accurate, do you have the data to show the conditions? Sounds like it was instantaneous peak at speed, not constant (i.e. on skid pad).
Right, those were max data points (spikes), I should have clarified. The sustained lateral loads we see on our STU classed M3 were rarely lower than 1.1g, however, per extensive DL1 data logging. Braking was also typically 1.0-1.1g pretty consistently. The AD07s are not R compounds, but they aren't just "street tires" either. :) I suspect a lot of the top "StreetTouring" classed Solo competitors have more tire testing logged than most OLOA racers? Just my theory. OLOA is a once a year event, whereas some autocrossers will do 25+ competition events a year and test excessively.

The one data point from last years' OLOA top skid padding Corvette, although meaningful, is not the end all be all lateral skidpad test number for "street tires", of course. Its surprising that some of the smaller/lighter cars didn't out-skidpad a Corvette... as we typically see when doing skidpad testing first hand. Although a Corvette tends to have a good "grip:weight ratio" (or tire width:weight ratio), its still a good bit lower than many other lighter cars, which can lay down quite a number on a skidpad (which itself is only part of the road course performance equation). That 1.07g lateral number is fairly average for a 140-200 treadwear autocross car.

The differences we see from surface to surface are also significant, and the skidpad at the Tire Rack test facility may be asphalt (I suspect it is) instead of clean concrete, which is usually faster.

Not trying to take anything away from OLOA racers or setups, just that those skidpad numbers may not be the epitome of the tires used. What impresses me is the fact that these One Lap drivers can go to so many varied tracks in such a short period of time and get clean, fast laps with no "offs" - this shows some impressive adaptability and driving! After watching some of the footage with events in the rain, cold, hot, dry, and everything in between over the course of a week - and with virtually no sleep! - I cannot fathom how they pull it off.

Cheers,

1.1 sustained is pretty impressive for your cars on those tires, do you have any data/screen shots to show? Maybe we can compare what the 135 does on the tires, see how that 5 link works :)

As you mentioned it also depends on the surface prep and conditions, quite significantly actually. The aggregate type can make or break your setup, especially when dealing with Autox and having dusty/sandy/dirty pavement, although it can very well be "sharper" than high speed road courses, as the surface is not worn down. A track is fastest when new, and the aggregate is "sharpest."

Only real way to compare the cars/tires is doing a skid pad run back to back during the same day at one facility.

I've only spectated at a a handful of events but so far I've seen crashes, lots of offs and one time even had to pick a car up off someone after it fell on him. Buncha loonies if you ask me. :D

Too bad they don't come through MI anymore I liked meeting those crazy people.

Carlos.

I remember '07 well at MAM...

I was walking through the paddock to see TC Kline sleeping in their car... then within an hour it seemed he was out on track trashing that car.

Was nice to talk to him at solo nationals that year in his Carbon R hatch...

I think the SRT-8 Jeep was pretty nuts to watch go around the track too.

Glad to see they'll be back to MAM in '08, bummer they're not going to MPH instead. Really anxious to see the Bimmerworld 135!! I'll be sure to wear my 'max hat'. :D

I'll be sure to wear my 'max hat'. :D

Good man!

More updates to follow shortly. The guys finished most of the work up while I was traveling last week and I have the pictures in the office. I got to drive the resulting car home today though. It was rainy, but that aside, it is AWESOME! More shortly.

updates?? I need moar.

Slammed here!! Will have it at VIR tomorrow. Today is the first day I drove it in the dry and with the LS differential. This thing is pretty insane... Will put up more pictures when I get to the track.

WCGT :) lol Bump it up to 600hp, toss in a sequential, slap on 280's all around and go for it.

Can't wait to see how the car does, such a sweet car!

sounds promising.

I know... Wed-Sunday at VIR, Monday in FL, and headed to VIR this PM for our World Challenge weekend - I have a little more on my plate than this one right now :) On the good side, we will be posting our One Lap blog so my co-drivers can keep you guys entertained while I am MIA...

sidewayz!!! I need an action shot with big tire smoke!

For the website of course ;)

Do the 135's take 335 diffs? Its not listed on your site...


Oh yeah, I second that you needs lots of media of this. I want to see you lapping m3's all day.

awesome. thanks.

thats awesome man!

quick question... when you guys got the LSD, did you stay with the original gearing or did you choose shorter gearing? if so, which?

Thanks!

How did I not see it at VIR? Did you guys actually bring it?

James had it out on the Wed. test day prior to the club race. It looked like a rocket ship.

Shorter, went to a 3.46 ratio

Any chance we can get some video of THE ONE on track?

We should get some good video duing One Lap.

I have been driving this car as well as a stock 135 and 335 and M3 a lot recently for an upcoming Grassroots Motorsports article. For ME, I prefer the traditional high revving NA cars like the M3s, new or old. This car has a lot of power, but it gets a little breathy high end because of the turbos. It is nimble due to size, but also a little less stable as well. Oil temp - we will see. Again, I don't think it likes being beaten on for 30 minutes straight.

BMW doesn't seem to have much history with Turbos.

Have you made exhaust changes? How is the spool up?

I think larger turbos, cams, and headwork can move your powerband up higher. From what I've read, BMW (largely due to all the NA purists) went out of their way to make sure these turbo 6s didn't have any hint of turbo lag. That unfortunately bones your powerband up top.

I always figured that Vic provided that service for you, but thanks for clarifying so that I can now make fun of him with more confidence in what I am saying.

Are yall coming to No Problem Raceway this coming Tuesday? If so...son of a bitch. I have two of my hardest finals Wednesday morning. Mother fer.

Thats OK - I worked until 5AM the last two nights... And got rewarded by getting screwed out of my connection today where I was invited to spend the night at O'hare. One way rental - not cheap...

James, you should have given me a call, I would have helped you out.

Mike

Me and a few people from my work are planning on being at the One Lap event this Tuesday at No Problem Raceway in Belle Chase, LA. Looking forward to seeing the car, and I promise to take some pictures for ya. hahaha

edit: I'll be in the (loud) Alpine E30 Tuesday.

I hate finals!!!

What tires did you guys end up running? I thought I saw "Michelin" stenciled on the side of them, but I know that doesn't mean that thats what they are ;)

Michelin PS-2s!

niceeee

Video is live on the blog. More updates later, but most of the info is going on the blog or being updated there.

Mmmmm, I love the sound of BOV in the morning :) Looks like its a blast to drive!

Is the ABS working well with the PFC? Sounds like its locking up briefly in a couple spots...but looks like its got some umph behind the brake pedal...now imagine if that thing was 800lbs lighter, fun.

Was the understeer mostly from the tires?

Also, did I read you picked up a V8 M3 for yourself? How does it compare to the One Lap 135?

The car looked awesome yesterday at VIR! You guys were flying.

Yeah, the PFC brake kit with 01s, combined with my braking technique is pushing through the ABS at times - which I prefer! We set the car up to understeer - something about having to get right back in and drive for 5000 miles in a week makes me err on the side of safe...

My M3 just got in before I took off on this trip, so it isn't close to broken in yet even. I did get to pound on some BMW cars though a few times recently. One of them was for a Grassroots Motorsports article that should come out next issue. They are just different cars. Our One Lap 135 that is pretty hopped up and seemingly on par with the M3 if not faster cists a little less than the M3 everything included. The M3 certainly has more headroom to go and I love NA power personally though...

Sweet. Yea...something about drifting for hours on end does not sound healthy for a car that needs to survive such a long trip :stickoutt

Definitely different cars, but it sounds like the fun factor is pretty close.

Its hard to replace the feel of instant response with the V8, but the kick in the arse from turbo's is fun too :redspot

Hmm...Turbo V8 :devillook
