drivinhardz06 Posted April 4, 2012 Share Posted April 4, 2012 With two long straights, it's a BIG track for our "slow" class and, at the top end, it's all about overcoming drag with horsepower. Did I go to the right Mid Ohio in Sept, is there another one I'm not aware of? Quote Link to comment Share on other sites More sharing options...
dans2k Posted April 4, 2012 Share Posted April 4, 2012 about Mid Ohio I felt like I lost tons of time on the carosel exit and keyhole since the car pushed so bad I probably at least made up the time over a non-tuned car down the straight but if they thing had got off the corners better it'd been a lot faster in the back section too Quote Link to comment Share on other sites More sharing options...
TurboShortBus Posted April 4, 2012 Share Posted April 4, 2012 Did I go to the right Mid Ohio in Sept, is there another one I'm not aware of? Maybe he went here instead...after all, it is also in the middle of Ohio: http://www.nationaltrailraceway.com/ Mark Quote Link to comment Share on other sites More sharing options...

Did I go to the right Mid Ohio in Sept, is there another one I'm not aware of? The other "long straight" that Mid Ohio folks refer to is the front straight (past the S/F line) to the Keyhole. Granted there is a turn in the middle, and T1 can bite hard if you mess up, but the distance from exiting the Carousel to the braking zone for the Keyhole is longer than the back straight...

We have to brake and downshift for 1. For us MidO is an autocross with dragstrip on the back. Quote Link to comment Share on other sites More sharing options...

speedengineer Posted April 5, 2012 Share Posted April 5, 2012 Typical lap average speeds for TTC: Road America: 91 mph Road Atlanta: 91 mph Mid-Ohio: 89 mph VIR: 89 mph Miller: 83 mph Other GL/MW tracks: Autobahn South: 78 mph Gingerman: 75 mph Grattan: 82 mph Putnam Park: 80 mph Excluding Road America, Mid-Ohio is far faster than the other Great Lakes/Midwest tracks. And honestly, average speed isn't far off from Road Atlanta and Road America. Minimum cornering speed for turn 1 at MO is 80 mph... Quote Link to comment Share on other sites More sharing options...
Fixxxercask Posted April 5, 2012 Share Posted April 5, 2012 build a drag car for Mid-O. Those turns from the end of the back straight all the way through turn 1 are not important! Proven by that TTR Lister at Nats. I've got video of him early in the event passing me out of T3; and he literally disappears down the backstraight. Then he slowed me down through the 2nd 1/2 of the track; but I assume he got better to turn a 1:27 something. Edit; found the video! My car in TTA trim put down ~350whp at Nats: That is disturbing to see how fast that thing is in a straight line. He made you look like you were parked practically.

drivinhardz06 Posted April 5, 2012 Share Posted April 5, 2012 And honestly, average speed isn't far off from Road Atlanta and Road America. for TTA and TTS MO to Road Atlanta swing is 7-9 mph, which is a good bit. TTR is 10 mph swing. it's about the same swing to CMP (our slowest regional track) to MO as MO is to Road Atlanta, and CMP is literally an auto-x with 40 mph turns everywhere you turn Quote Link to comment Share on other sites More sharing options...
Rob S. Posted April 12, 2012 Share Posted April 12, 2012 I was also in the middle of that range. I have an AP2 motor though, which are known to make more hp than AP1's. (Thus we get stuck with the TTC base class rather than the TTD** base class). Is this a NASA approved engine swap; S2000 (2.0L) '00-'03 with a '04-'08 2.2L engine and TTC base class? I didn't see anything in the rules allowing a 2.2L swap from an AP2 into an AP1 car with a new base class of TTC. Greg removed all the pre-approved engine swaps this yr from the rules. Also even if you use the TTC base class of the '04-'08, are there any other components (shocks, springs, sway bars, control arms, etc) that are different between the '00-'03 and '04-'08 models? He could have provided an approval letter........just curious. Thanks. Quote Link to comment Share on other sites More sharing options...

Members Mike W. Posted April 13, 2012 Members Share Posted April 13, 2012 This discussion does bring another question, how long is a dyno reclass good for? I have seen some cars with a few year old dyno reclass but the same car with a new dyno reclass is different. Both NA 1.8L Miatas both PTE/TTE Older dyno reclass 135whp @ 2340lbs (at least two years old if I remember correctly) New dyno reclass 129whp @ 2330lbs (From a week or two ago) Clearly things change every year but if a new dyno reclass is not requested then the car is basically running using the older rules. Just food for thought. Mike Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted April 13, 2012 Share Posted April 13, 2012 there's a cutoff date listed in the ruleset, new for this year. page 13: All Official re-classifications sent by the National TT Director prior to January 3, 2011 must be re-submitted so the re-classification can be verified, and an updated Official Re-Classification e-mail can be sent.

Members Mike W. Posted April 13, 2012 Members Share Posted April 13, 2012 It looks like it is also covered by this on page 33. "Any vehicle that has been re-classed by the National TT Director and has had a change to either its base class or its base weight in the table in Section 6.3.2 since the re-classification was approved, MUST be re-submitted for re-classification." But how many people have actually done this? Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted April 13, 2012 Share Posted April 13, 2012 That is only in cases where your particular vehicle's listing changes and there aren't a ton that change. My car's listing hasn't changed since 2005. There are so few that change it's not too hard to stay on top of them, esp when it's a popular car like say a Miata.

Rob S. Posted April 13, 2012 Share Posted April 13, 2012 Jason - Just curious again. Isn't the AP2 ECU reflashable while the AP1 is not? Does the approval allow the use of the AP2 ECU also? Do you have to use the AP2 ECU with the 2.2L for it to work properly? See where I'm going with this......might have to get an S2K with a 2.2L for TTC. Thanks.

AP2's from 2004 to 2005 are not reflashable. In 2006 the car went to drive by wire, and those are reflashable. Those still have the same base class as 2004-2005 AP2's, which sucks cause you basically are shorted by 3 points if you want an ecu. Yes, I use the AP2 ECU with my AP2 motor. If you don't, you have to use a fuel controller of some sort to get your air-fuel ratios right. There are minor spring/rollbar differences between the years. Not a significant change. AP2 chassis' have revised bump-toe in the rear since people were spinning their AP1's out on the street...I've never noticed an issue with my AP1 chassis. AP2 has different gear ratios than the AP1, to work better with the lower redline. Haha, giving up with the 240 already? You and Dominic should just run TTC all this year, we'd have huge fields. If you switch this weekend, that'd be 7, maybe 8 of us! Quote Link to comment Share on other sites More sharing options...
Rob S. Posted April 13, 2012 Share Posted April 13, 2012 Thanks for the Info Jason. Always weighing my options. I think my 240 has a chance in TTC. I'm definitely out horsepowered in TTB. We'll see what configuration I can come up with for Nationals. Quote Link to comment Share on other sites More sharing options...
sfteague Posted May 31, 2012 Share Posted May 31, 2012 I'm in the process of building a TT-B car from my e46 M3. People keep saying e46 should be a good TT-B car, but I'm surprised that there don't appear to be that many e46 M's getting used in TT-B yet. e36 m3's seem more common in TT-B, but I wonder if that has to do with the e46 m3's only recently starting to be really affordable on the used market. I've only run my e46 in pig mode (full stock interior, etc.) on 18x9.5 R888 245's, and coilovers. I believe that I'm way over the 3415 base weight with me in the car. It seems plausible that if I drop weight down to 3415 with me in it, and slap on 275mm A6's on 18x10's, I could be in a position to have a competitive car (of course, dependent on driver skill). Some Evo's also seem pretty fast in TT-B. Quote Link to comment Share on other sites More sharing options...
