** is on the list of points. Yep, yep and yep. And I'll take that as a challenge. You've got to think, yes the STi had a decent suspension setup, but I can run almost 100 more whp with the Evo. And with VIR being a horsepower track I think I could come pretty darn close even without coilovers.

Uhhh whachu talkin bout Willis? SpecZ06 mafia boys all usually run faster than TTS down there don't they?

The car can only have parts on it that came with the base model sold here in the US. The rear bumper would get dinged for rear fascia and diffuser. Also, just because it doesn't say you can't != legal.

Well boo then, lol. I guess I haven't read them that closely since I don't plan on running TT till mid next year and who knows what will change in the rules for next year.

Ya the spec Z06's run a good .2-.5 faster than TTS at all southeat tracks except for Road Atlanta know that Hessami set a new tr this past December.

we know hes prolly 200+ lbs over the limit. its a totally stock car as far as weight reduction. plus the drivers, so hes over by a bit. we know its fast as well, i suspect if hes over, its by 10-20whp max. and honestly, with the extra weight it currently has, i wouldn't be surprised if its legal.

we always street tune, i don't have a dyno. the only time we use the dyno is when someone wants numbers. in this case we need them for the power to weight ratio. hes got 126k miles on the car with countless HPDE days, and been tuned for 100k miles or so

jim has only run 1 full day of TT. the first event he got signed off on, and the second event, he corded the tires the first session of the second day.

you can legally put the 10.5 hotside from a 2005 evo on your car though. same with the mitsu front LSD from a 04 RS/2005 all models in the transfercase. both for 0 points the LSD is a HUGE improvement on corner exit. well worth the upgrade!!!

I feel like a broken record on this TTA vs TTS deal.
This isn't the case in the MW/GL. Many of the former TTA SpecZ06's have (including past National Champions) have moved into TTS/ST-2. And I think all of them are still active in TTS/ST2 or TTU/ST1.

• 2010 TTU National champion Vette - Great Lakes region
• 2010 TTA National champion Vette - Midwest region
• 2009 TTU National champion Vette - Great Lakes region
• 2009 TTS National champion Vette - Midwest region
• 2009 TTA National champion Vette - Great Lakes region
• 2008 TTS National champion Vette - Great Lakes region
• 2007 TTU National champion Vette - Great Lakes region
• 2007 TTS National champion Vette - Great Lakes region
• 2007 TTA National champion Vette - Great Lakes region

Of course there are some slower TTS guys; but that happens in every class. There's several TTS & TTU cars I regular run faster than even in TTB trim - some because they probably don't want to ball up their 60-100k car (C6 Z06 or Vipers or Porsches).

Would you say that most NASA TT cars are specific prepped time trial cars, or mostly street cars that people race TT in?

Im curious because i race and put on TT's with the SCCA. We have a few levels that all require different safety requirements. Mostly tho, you will see level 3 TT's (Track trials) which requires at least a roll bar, driving suit, 5 point belts, etc. We end up having more cars that end up on the full race car side vs the street car side. (which takes away alot of potential racers). And i really believe we need to open it up more to street cars. I'm trying to change this alittle in my region to help grow the sport with the SCCA.

I would've never thought that TTA and TTS were the same HP/weight. I'm way past TTA so i really never even looked at those class requirements. I'm thinking that i might be able to squeeze into TTS. (maybe)

It's a mix. You've got people just working their way up from HPDE, people that really like TT, people that balance it with racing (dependent on track and travel distance what they pick), people with helli-expensive cars and people that used to race bringing a fast car for fun.

If I had to put a split, definitely less than 20% are fully race prepped. Maybe 50% have a cage or rollbar with some race prep. Lots of others with 3pts or 4pts that either drive it to the track, or have access to a trailer to haul their DD/weekend car to the track.

NASA only requires a 3-pt belt for TT. TT follows the HPDE safety guidelines. Although everyone in TT is well aware of the dangers and speeds and it's formally mentioned usually once a weekend about seats, belts, HANS, cages, etc.

Nate, you notice I did prefix my post by saying NASA-SE (not mid west or such). Part of what happens in NASA-SE is 4 events each year at RA which is a track that really plays to the Vette's strengths. Here's TT results from RA last fall:

TTA
1 71 Mark Nunnally TTA 2001 Chevy Corvette Z06 1:31.519
2 27 Scott Perkins TTA 1999 CHEVROLET CORVETTE 1:32.933
3 7 Jason Ireland TTA 2002 Chevrolet Corvette Z06 1:37.489
4 83 Robert Boyett TTA 2006 Pontiac GTO 1:40.191
5 4 Brian Bowers TTA 2001 Chevrolet Corvette Z06 1:40.384
6 141 Tal Isbell TTA 2004 Ford Mustang 1:41.513
7 95 jesse felder TTA 1998 ford mustang cobra 1:52.383

TTS
1 17 Walead Hessami TTS 2001 Government Motors Corvette Z06 1:30.531
2 14 Brent Dalton TTS 1993 Mazda RX-7 1:35.281
3 88 Khoi Nguyen TTS 1998 Chevrolet Corvette 1:36.383
4 196 Team Werner Law TTS 1999 Chevrolet Corvette 1:37.003

10 02 Randy Kornegay TTS 1983 Royale S2000M 1:48.722
11 3 alan palmer TTS 2000 Dodge Viper

TTU
1 46 A.R. Hoshmandy TTU 2007 chevrolet zo6 1:30.642
2 48 Mark West TTU 2009 Nissan GT-R 1:31.321
3 44 Larry Carter TTU 2010 Dodge Viper 1:32.101
4 63 Todd Rumpke TTU 2006 Chevrolet Z06 Corvette 1:35.324
5 9 Bob Cornick TTU 1998 Dodge Viper 1:43.991
6 188 Jerry Stout TTU 2006 Chevy Corvette Z06 1:51.716
7 98 Reese *** TTU 2006 Chevrolet Corvette

For reference, AR's vette in TTU is a HIGHLY modified C6 Z06 and Mark West's GTR is a gutted pure track car. As Shaun noted above, the only all-out purpose prepped car in TTS is Walead. Brent's LS1 FD is getting close, but after that TTS down here is filled with folks who either a: don't drive hard or b: have a car that is slightly out of TTA points, but nowhere near a purpose built TTS car.

The point I am about to make may have been made already... But I will say it any way. The rules for time trails were changed for 2011, Nathan and I have already talked about it, but im my opinion.... I dont think anyone will be albe to leagally run 408ahwp in TT-A...

From the TT rules...

"The minimum “Adjusted” Weight/Horsepower ratio (defined in Appendix C) for any car
in TTA is 8.70:1, regardless of how many points it has, or which base class it begins in."

"Each class has been assigned a minimum “Adjusted” Weight/Power ratio. Regardless of
how many points a car has, or which base class it begins in, it may not exceed the minimum
“Adjusted” Weight/Power ratio for its competition class. Any vehicle found competing
with an “Adjusted” Weight/Power ratio less than the minimum level assigned below will be
disqualified, and additional penalties may be assessed.
TTA 8.70:1 TTD 14.25:1
TTB 10.25:1 TTE 16.50:1
TTC 12.00:1 TTF 19.50:1"

Just doing a rough initial p/w on a Nathans evo at 3266/408 = 8.00. I didnt take the time to run it through the actual form, but it would be hard to make back that .7. especially when you can only add 250 lbs of ballast per NASA tt rules.

For example, my evo is st2... equal to tt-s. my comp weight with me in the car is 3050 with a max power 357 on a 275 dot slick.... Thats me more or less maxing out the tt-s / st-2 rules...

hamy; not sure what your getting at here?

Yeah; that's an 8.0 power/weight ratio. Then once you and in the modifiers assuming a 245 or smaller tire you get .7 back and it's 8.7 Thus; legal. Now can you make the power legally with the points available; I dunno.
MSP608 sounds like he's going to try that route so hopefully he keeps us posted.
