Will post more details later.
Heading out for a drink!
Dyno was today. Ran with a bad bypass valve, was losing boost:

looks good . Congrats.
What mods have you done to your motor?
I would be a bit hesitant on the AFRs from 4500rpm (red curve). Richen them up a bit to be on the safer side (red curve). However the blue curve looks great.

looks like a supercharged application. but specs would be nice? also yes the car is making such good #'s cause it is a hair on the lean side it should be closer to 12 a/f.

This is a KO Performance Stage III nice job Brian. I have this exact same software on my car. The dyno AFR's don't match the street AFR's they are perfect. I get 12.2 to 12.5 on mine with the same software.

Great story about this car Brian bought it from someone who wanted to do exactly what Brian did to the car but went to the wrong people. It is about as horrific of a story as you can imagine. Brian stuck with it came to KO and now has a monster of a car. Thanks to Marco and Karl for helping Brian through this very difficult transformation. Patience is a virtue and this shows that. Brian did the work himself and got it done.

I just hope Brian shares this dyno with the former owner who was oh so close to coming to KO but chose a different route and the nightmare began. Congrats Brian and enjoy. Come to Road America and lets school some P-cars.:)

Thanks Cody for showing my #'s.
I am the owner and yes it is a SC motor.
Basically I bought the car from Chicago and long story short found #3 piston ring landing was cracked due to a terrible sc set-up. I had the engine bored
.25 over, put forged Wiseco pistons in along with forged rods, and built it from the ground up.
Yes it was all built by myself. Wow, long 6 month process but completely worth it!

Thanks to JimM3,Marco,and Karl from active I was able to do this right the first time. If not for these guys I would been in serious trouble. Also thanks to Steve from Head Werks for all the machine work!

So if this is a KO Performance Stage III and he bought the car with the supercharger already installed...did he sell that system and then buy your's? or did he just install your software? If that is the case, then who's hardware is it? :confused

Please explain exactly what was done in detail cause it's all very fuzzy information right now.

Why did you guys need Karl's help if it's KO S3 software? I'm confused. :confused

Really nice pictures BTW. :thumbup:

Okay when I orginally bought the car it had a ERT SC system. Basically the ERT uses a vortech v2 blower which is good! what I didn't like is it uses a huge fuel pressure regulator vs. bigger injectors. This system was meant for 6.5 psi boost, nothing more. Will the previous owner took it to a performance shop in Chicago which I don't think I can metion their name.

The shop said they could increase to 9 psi. with the same system no software,stock injectors, etc, etc... and they converted it to obd1.
Well found out of course after I bought the car, that they blew the head and the piston sky high while doing a dyno. Way leaned out.

I basically kept the blower, went with the RMS brackets,RMS aftercooler,and KO injectors and software.. KO uses Active Autowerkes for tuning and injectors etc.. Karl is one of the software engineers for AA, smart,smart man!
JimM3 is the one that found my basically cry for help when all this went down.
He knew this system was all ass backwards and hooked me up with the right connections. Marco is about the closest thing to god with knowledge and helpful info to get me through all this. This guy took one look at my orginal set-up and named off 10 things all wrong. Without him I would of been screwed. He has stepped me through just about the whole way. I went from knowing nothing to almost everything from him.

Thank you again guys for the help.

Marco's extensive knowledge and expertise for the Vortech setup and the S52 layout comes with a great deal of experience and technicalities, nevermind the keyboard. He really knows these sytems inside out.

-As for Brian this is a great outlook on how my system will perform once i clear the damn ghost out of my machine. Glad to see you are making good progress with the new software and hardware. :alright

The whole idea for a packaged stage III came from research and work I did on these kits. It was a collection of ideas wrapped into a package and tuned. KO facilitated and AA help tune it, Marco supplied the technical expertise. It is a collection of parts that takes a stage I Vortech kit and takes it to the next level.

I worked with the former owner of Brian's car for sometime and he was ready to go with the KO stage III but instead went to a "reputable" Chicago tuner who is supposedly well respected. They did so many bad things to the former owner it is just sad. Brian inherited the mess and we sold him stage III. Marco helped a ton, we have been working together for quite awhile perfecting this system. Karl just plain nailed the software with our Stage III car we had at AA. Marco then got it fine tuned and this is what you see in this dyno.

The beneficiaries are the people people who have Dinan and RMS kits who want much more power. The cars are incredible and still very much like the original M3's characteristics, but a lot more power.

Hey Jim, I took your advise and called the previous owner John, I told him to take a look at this thread.

Of course he probably would never had the car for sell if he did and I wouldn't be where I am today.

Found interesting fact from Marco today regarding and proving how will this tune is performing. Marco went to dyno and conducted alittle experiment ran acouple runs on pump 93 and then added some race fuel and ran acouple runs.


Found out the race fuel actually hurt his Horse power then straight pump gas.
Proving this is a excellent tune.

Marco ran 430 rwhp 330 torque on pump 93 gas 2 times, then added 1 gal of 108 to 6 gal of 93, lost 25rwhp on the next 2 runs on the dyno showing how good this tune is.

All that proves is that the original tune was not tuned specifically for that race fuel mixture. Any car that is tuned for 93 octane is going to lose power with higher octane fuel above 93 without more PSI. On a turbo car higher octane + stock DME allows you to turn the boost up more. A standalone like the Tec3R is good for race fuel because you can do a completely different tune using much more ignition timing than pump gas will allow which increases hp and tq if added correctly. ;)

The race gas richins the mixture which would cause the loss in power.

Okay, let me re phrase my statement "Proving it's a good tune"
It shows it's a safe, non-aggresive tune.

So if you did a dyno run with a higher grade of octane, your sniffer would actually record a significantly richer AFR? Damn. I didnt know this. Does this mean that cars that are tuned for regular and the owner runs 93 octane is going to lose power also? Or does it have to be a car tuned for FI, in that its tuned rich as it is, which would suffer with further enrichment from a higher octane grade?

I see what you are saying. If the tune was way too lean then richening it up with higher octane should yield more gain rather than loss. Gotcha! ;)

Is the stage III upgrade available to the public? It says coming soon when I visited the website. Can you perhaps enlighten me on the differences between the stage II 11psi kit (~325whp) and the stage III kit at only 9.5psi making over 400whp? Thanks.

Jim, just curious.. Does the M50 manifold lower the boost level slightly over the stock manifold? As you probably remember, When I combined the 6" crank pulley with the 3.33" sc pulley, when we went to the 3.5" hfm, aftercooler, and the rest of the setup like your stage II, we made over 12 psi, and thats why we had to go with the 3.48" pulley; to bring it back down to just shy of 11. Only difference I can see between your stage II and my setup is the manifold.. Any other explanation as to the boost difference?

Yea.. so how come some folks with the 6"/3.33 combos make 11 psi, and others made over 12 like me and had to run 3.48

remember what you see on the gauge is residual manifold pressure. so what you see on the gauge is whatever your motor cannot proccess. a perfect example of this is when you do nothing else but add cams to a charged m3 what happens. you make more power and show less boost on your gauge. are you really making less boost? no, because the blower is spinning at the same rate.

>>residual manifold pressure<< Huh? Maybe with cams, but i dont have cams. You mean, running a boost gauge off the same line thats feeding the aquamist, and bpv, and brake assist, etc, is giving us bogus boost readings? Damn.. So where am I supposed to get accurate boost readings? This is the first Ive heard of this. After all, 'boost' or vacuum, I thought was defined as boost/vacuum as it appears in the manifold, and thats what we're reading. Since virtually everyody taps the manifold for their gauges, is Everybody out to lunch with their boost reports ???

cams was only to show an example. if you change your cams the motor becomes more efficient, so the pressure reading in the manifold (gauge) will drop from just installing cams, or headers, or track pipe and so on. you may want to pick up "supercharged" by Croky Bell. it explains this in more depth. that is why when you run the 6/3.33 you show 13psi and when i run that combo i show 10.5-11psi. my motor proccess more boost due to the cams.

George -

Are you sure about this? I don't believe that higher octane as is any "richer" than lower octane gas -- it merely has a greater ability to withstand pre-detonation (and burns more slowly).

Stoichiometric is the same regardless of octane.

Neil,

High(er) octane has a higher specific gravitiy. The hydrocarbons are more saturated, creating a "richer" mixture. Sotic wouldn't change as it is still petrol based.

Ok.. I think i got it now. its why sometimes, cars with alot less boost make alot more whp.. If removing the restriction after the compressor (running less restriction) lowers boost, it might run more power with less boost.. Assuming that placing a restriction in front of the blower lowers boost, but behind the blower raises boost, and vice versa, then I would think the less restrictive M50 manifold would tend to Lower boost, since its removing a relative restriction from behind the blower, as opposed to removing the restriction in front of the blower which raises boost like when we replace a 3" hfm with a 3.5"hfm. It sounds like it makes sense; does it work out in practice re the manifold?

You got it Paul, pressure (psia,psig,kPa) is a measurement of restriction to flow. Volume (flow) is what matters in terms of power.

Exampe:
A 5.0 litre motor and 2.0 litre motor require the same flow to reach the desired HP, but the pressure to equate such power varies.

considering that, you are probably at a higher compression rate then the rest of us, so yes that would contribute to it. it all has to do with flow.

Assuming that placing a restriction in front of the blower lowers boost, but behind the blower raises boost, and vice versa, then I would think the less restrictive M50 manifold would tend to Lower boost, since its removing a relative restriction from behind the blower, as opposed to removing the restriction in front of the blower which raises boost like when we replace a 3" hfm with a 3.5"hfm. It sounds like it makes sense; does it work out in practice re the manifold?

:alright yup. again i am going to try to find that section in the book for you and scan it. it is interesting. with out a change to the blower or pulleys, anything you do to the motor to "flow" better will increase power and lower the manifold pressure. and i say manifold pressure cause you realise the "boost" is constant (we did not change blower or pulley's)

George -

Are you sure about this? I don't believe that higher octane as is any "richer" than lower octane gas -- it merely has a greater ability to withstand pre-detonation (and burns more slowly).

Stoichiometric is the same regardless of octane.

Neil,

Just a pet peeve, repeat after me:

Detonation

Pre-Ignition

They are not equal, and there is no such thing as pre-detonation, unless you are merely referring to the time prior to detonation! It in and of itself, is not an "event"!

OK, I said it and stand corrected (twice now in this thread).

Nothing personal Neil!!

No reason to lurk, just hit one of my hot buttons, right up there with "dampening" when referring to suspension components...

Re-tuned (Slightly) and we hit 462 rwhp! Good times... what a fun daily it is.

Getting image from camera, will be tossing up soon.

My boy has been super busy moving into his new pad. All images are on his computer...
Hopefully soon he'll send over the .jpgs

Okay when I orginally bought the car it had a ERT SC system. Basically the ERT uses a vortech v2 blower which is good! what I didn't like is it uses a huge fuel pressure regulator vs. bigger injectors. This system was meant for 6.5 psi boost, nothing more. Will the previous owner took it to a performance shop in Chicago which I don't think I can metion their name.

The shop said they could increase to 9 psi. with the same system no software,stock injectors, etc, etc... and they converted it to obd1.
Well found out of course after I bought the car, that they blew the head and the piston sky high while doing a dyno. Way leaned out.

I basically kept the blower, went with the RMS brackets,RMS aftercooler,and KO injectors and software.. KO uses Active Autowerkes for tuning and injectors etc.. Karl is one of the software engineers for AA, smart,smart man!
JimM3 is the one that found my basically cry for help when all this went down.
He knew this system was all ass backwards and hooked me up with the right connections. Marco is about the closest thing to god with knowledge and helpful info to get me through all this. This guy took one look at my orginal set-up and named off 10 things all wrong. Without him I would of been screwed. He has stepped me through just about the whole way. I went from knowing nothing to almost everything from him.

Thank you again guys for the help.

Man, I seriously almost bought this car last year. Had a weird vibe after 2 long phone conversations and bailed the day I was supposed to drive out to Wilmette to take it for a drive. Glad I didn't because it was at the limit of my budget, and I would have been screwed if I had to go thru all that trouble. You've done great with the car though. Now I'm jealous :D
