I see that Rory Alsberg ran a 2:26.297 at RA this weekend in a CSI PERFORMANCE prepared TTA "legal" Vette. Seems like a decent time what do you guys think? Chris Griswald was there with his 800 horse RUSTANG and was said to have reached 192MPH on the front straight. Joel from CSI asked him if he saw GOD at that speed. Chris said something to the effect "I didn't have time to look but I know he was close!"

That is very fast in TTA. Maybe a track record? Gezz I hope my car fits in TTB!

The old TTA record was 2:29.752. Rory is a great driver and no doubt that time is flying.

Edit: I think T1 cars run around 2:22 ish around there.

2:26 is plenty fast. The T1 record at the Run Offs is 2:20.0XX. STO is 2:15.0XX. I don't know how these classes compare to PTA.

TTA/PTA is basically stock C5Z on A6's with T1 bars and some lightening. Usually ~365 RWHP tune.

Usually I am in the car but it was fun watching Brian in this weekend in the PTA car, we are going to get some Duramax emblems for all the cars because they sound like the Audi P1 Diesel cars compared to a T1 or ST2 vette, they just go "whoosh" when they go by everybody is always amazed our cars still have cats/mufflers/factory exhaust. I guess corvettes are supposed to be loud.

T1 cars have a better hp/wt than the TTA/PTA cars - closer to 7.9 - vs 8.4 for TTA/PTA
Bigger tires 315/345's vs 255's or 275's for TTA/PTA
Stiffer springs/shocks are open/bars - for TTA/PTA it's pretty much pick one.
PTA/TTA cars do get to remove most "non-essential" items for weight reduction - but we still can't go under 3118 - (Rory's car was closer to 3200 all weekend)

2.26.xx was a great lap and I think it will stand for a while - it took 4 years to get it back from Ryan Gates and his Evo. But as with most TTA records it's back in the Corvette camp where it belongs.

Great run Rory!

LS2 T1 car weighs 3280 and tune is only engine mod and most of us self financed cars are under 400 RWHP. I still have stock tune with 346RWHP. Stock airfilter housing to exhaust manifold. Exhaust is then open but must meet sound. I run cats but no muffler to stay under the limit.
I can run up to 315 tires but the newer LS3 cars can run 345 rears with 50lb added. T1 or stock sway bars with matching leaf springs. No coilovers and no aftermarket bushings. Aftermarket brakes gets you another 50lbs. Stock dash but door panels and carpeting can come out as long as you meet weight. No aero mods. Seems like some of the T1 cars would go into PTA + or ST2-. T1 cars are a lot closer to stock than PTA or ST2.

With a new engine I'm at 8.4 lbs/hp and I think that's pretty typical for all the C5 T1 cars. Up until the new engine I was over 8.7 lbs/hp. I'm hoping poly bushings will be allowed in T1 as that would help the platform quite a bit IMO. I think C5 T1 cars were running 2:24-ish at Road America with Tom Sloan putting down a 2:22 in qual.

drivinhard

you mean the C5 T1 ones with the $15k B&B LS6's, $5k Moton's and Penske's and $3k AP brakes and springs and headers and straight pipes

PTA = T1 sway bars, gut the heck out of the car, 275's or 255's, stiffer bushings, light weight clutch.

ST2 is another animal, same power to weight, mods are only left to your checkbook size

Fast to slow
Million $ T1 car driven sponsored by Loan Shark-Ferrarri or similar
ST2 car
T1 car normal rich guys
PTA car
T1 car poor guys (like me)

I ran 2:28 with a full weight street Z06 on stock suspension with about 650 hp.

192mph on the front staight - Is that GPS verified or just speedo?

Add a row at bottom for out of shape old guys living in a van down by the river who lift for kink and brake way early in T1, T% and Canada. Mid to high 2:30's.

I'd be interested to know this also, an LMP1 car hits about 185 there so that must be one hell of a mustang lol.

Who Needs 400+ RWHP when you have a PTA car

drivinhard

The Diesel P1 cars will hit 200+ at Road Atlanta, I always thought Road America had longer straights? (or at least a longer straight)

Rory spanked everybody at nats so obviously he can wheel, with a stout car, yet the spread to the T1 lap times is bigger than any track I've seen comparing the 2 classes, proving that Road America is a true hp track, as the 7.x power/weight much trumps the ~8.4 or so allowed in TTA. Also I think Rory said he had never driven there in a car (has done 2 wheels) so he may have more in the bag as well.

Zeigler was 4 seconds off Rory at Road America (and only a couple of tenths off Rory at MO nats).

Yeah, I'm not seein' it either.....

Just for fun;

- LMP1 car weight to power ratio is approximately 2.84 lb/HP, speed is 185 at RA
- for the Mustang (or any car really) to go 185 it would need to be fairly close to that ratio, which means that at 800HP it must weigh 2272 lbs, and that might allow it to hit 185, not 192.

And, for the Mustang (or any other car) to hit the same speed as a LMP1 car its entry speed to the front straight would also have to be pretty close to the entry speed of the LMP1 car - not gonna happen IMO.

All the above does not take into account any aero aspects of the LMP1 car or the Mustang - obviously the LMP1 car makes a ton of downforce which does tend to limit top end speed. And of course the downforce is needed to make it through T14 alive with a high entry speed to the front straight, which enables the high terminal speed on the straight.

Again, just for fun.

UPDATE - see next page, if the car really makes 900HP everything changes.....

Wow, great job Rory, that's flying with that level of prep!
