Here's my video from Sundays race. It's the first video I've done start to finish, so please excuse the text that pops up at the 4 min. mark :confused . It also comes up later when it's appropriate. Critique away :D

Nice video - Who was in the silver car?

Also, did you notice your (what I assume to be) oil pressure light goes on in a couple of those turns? It doesn't look like it is on when you are accelerating, but that would freak me out.

Also, you car appears to be geared almost perfectly for that track with very little shifting necessary and only a couple of places where you ride the rev-limiter. Does that hurt the motor any?

I guess I never really realized that Mid-Ohio had so many sharp turns. I thought it was more open and flowing. Just a mis-conception probably.

Are there different configurations at Mid-O?

Nice little battle ya had there.

I hope thats the Wind Buffeting thats bad...thats what I am assuming that weird sound is?

What Diff do you have? You are lifting/spinning inside tire quite often, do you feel this slows you down? Have you had any overheating issues with the diff?

I guess I never really realized that Mid-Ohio had so many sharp turns. I thought it was more open and flowing. Just a mis-conception probably.Never having been there myself and just seeing TV and in car vids, I still can't match the track map with the TV coverage in my head. It looks totaly different from in car as well. I dunno, perhaps something about the TV camera coverage, but every other track is easy to match the coverage to the track map.

Nice vid BTW! Thanks.

The silver car is Sean Tillinghast. He is very fast, but had some mechanical issues all weekend. He is teething a new car, since his incident at the Mid-Ohio Grand-am Cr last August. I will note that his car is almost 300lbs. lighter than mine at the moment. I need to put a lower pressure switch on my oil light. I have a 3.46, but a 3.64 would be better. I get pulled off the corners by the guy's with taller diff's. It's a technical track, and when you get it right, it's fast and fun :D

Can you also lose the 300lbs or not?
Leave the higher pressure light switch in. If you really DO have a problem, it will trip off much higher. I like the 30psi units.
I think you meant you want a shorter, not taller, diff. Shorter means shorter gearing, taller means longer gearing. With a 3.64, you'd have one more shift up or else you'd be riding the rev limiter for a much longer period (and at a much slower speed) on the second half of the track.

We were running the club course(with the chicane before the keyhole). We'll run the pro course(no chicane) in June when CR runs with Grand-am. Yeah it's the wind, my camera is close to the passenger side window. I have a 3.46 diff. I've been working on the set-up to cure that, but I'm still running an I-stock suspension set-up, so I'm limited on the adjustments. I need stiffer springs,rear spring adjusters and some front coilovers. It probably slows me down a bit, but I've learned to deal with it until I can get a new set-up. I have a finned diff cover and haven't had any overheating problems.

I think I can lose about 150 or so. I'd need to put it back in ballast for IP, but would be fine for NASA GTS 3. Trying to find a balance for both series. I'd rather have the 3.64 and shift a few more times. I think it would pull off the corners better, but I may be wrong, I'm not that smart, I just drive the thing :stickoutt Mine's a 25 or 30psi I think, it only does it when I get off throttle on a hard run. I keep an eye on it.

Gotcha.

I meant what actual lsd do you have, is it a stock 3.46, or was it built by diffsonline or something?

Seems while you obviously have some jacking going on back there, it will be cured with some new suspension thats optimized for IP. But, have you thought about getting a higher % lockup, could help get the power down coming out of the corner.

As far as gearing, its compromise since you are only changing the final drive.

While with a shorter gear you will be accelerating the motor faster, your mph in each gear will obviously be lower, so covering less ground in some situations. If you really want to get the edge when the time comes, i can crank out some gearing/speed charts for you, and you can compare it to each track and help you decide what gearing to use. Its pretty easy to determine final drive, as its just one number to change in the equation. Its when you have to detemrine the final drive AND each gear (i..e hewland/xtrac race box) for each track, so you can optimize every corner in every gear at all conditions. But there will always be atleast some slight compromise.

It's not stock, but only at 40% right now. I'd like to get the ramps worked on, so I can get like 75%. It think it's either one of Dan's or Blanton's. The shop that used to work on it, put it in and not sure which one they got it from.

Good race, thanks for posting the vid.

Sean Tillinghast got a new car? I was under the impression that the accident there last August left his black car in bad, but fixable condition.

Nope, The black car was totaled. Transfered the good parts from it to a "new shell.

If you only have a 3.46 and an I-stock suspension then the IP guys are in trouble when you get coilovers, your 3.64 (or 3.73) and a weld in cage that stiffens up the chassis. That car has good ju-ju though, Bob Biggs was also quite fast in it when it was an H-stock/I-stock car. :D

For one the TV guys have their head up their azz when it comes to Mid-Ohio. I'm not sure they quite yet realize what part of the track is Madness. The only time that they ever get it right is when a racer is up there commentating, like Johnny O'Connell or someone like that. Further confusing things is that they don't run the chicane for pro races so what we may refer to as turn 7 is turn 4 to them. 2nd I think the TV angles do confuse you, I've been to Mid-Ohio a lot so I know where they usually are but the angle facing the cars driving under the Honda bridge is a little confusing. Same thing happens to me when I watch a VIR race, the TV camera makes the rollercoaster and hog pen look a lot different than they do from inside a car. That's my 2 cents anyway.

nice vid......

I was wondering when/if youd pass the silver e 36. Nice hand shuffle.......:stickoutt


sent u a pm

nice vid/drive. thanks for posting.

Thanks for the video. I am going there for the first time for a DE in May. Did the track get repaved??

Thanks,
Chris

Yes it did. New curbing and NO concrete patches. Just really grippy new black pavement. I was 2 seconds a lap faster on old hard Hoosiers than new ones, but that may just be me.

Scott drove a great race and had an overall fantastic weekend. Like he mentioned, I was dealing with my own little set of issues. There are lots of parts on an race car and everyone of mine was recently dismantled and reassembled onto a new chassis. It was pretty amazing that I didn't have more issues than we did.

Like most projects I was down to the last minute getting everything pulled together. The car had a terrible miss which we just couldn't figure out and what ultimately ended my race (in Scott's video you'll notice that I pretty much stop after exiting the key-hole). The car made okay power above 5500 rpm (224 rwhp on the dyno) but stumbled all over itself below that which made made the mid-corner and track out speeds pretty pathetic.

We had a great time despite the blown power steering hose, blown power steering pump, ingnition problems, loose half-shaft bolts, and ultimately a dropped valve or two.

There was a qualifying sprint race on Sunday which was a hoot. I had to start from last and make my way to the front. Unfortunately I didn't have the video camera rolling as it would have made some fun footage.

My hat's off to Scott for a good drive. Thanks to Paul Hamm for the support all weekend. Finally, thanks to Tom Hatem of THA and Brian Hoover of Autobody Specialists who both contributed time and resources to getting the #001 on the track in fine fashion.

You forgot to mention, loose brake brackets, brake lines etc. :D :D Like I said, when you get it sorted out, look out !!! I also forgot to thank You and Tom Hatem for all the help at his shop on Fri afternoon. I could never have found the problem and fixed it without it. Looking forward to getting back out there and having some fun with you and Paul. Hope to see you guy's in three weeks @ Putnam :redspot

Oh yea, I forgot the braking issues. But who needs them? They just slow you down :help
