How is ST2 a lower power class? It's 8.0:1 now; 7.6:1 on 275s. That requires 410-420 rwhp which means a cam and headers in a LS6. Why can't a 9.5:1 C5 run AI. I've been on track running Boss Mustangs in ST2 and they're plenty competent around the track with equal power/weight.

except the boss mustangs that i think you have been on the track with have full aero packages including vented hoods and if its desalvo and winkler, they are running slicks as well. not dot tires.

if you put them on 275 r6's and take the aero away, they are not going to keep up nearly so well.

If they were running slicks then they were cheating. The times I've been out there they've been in A6s which is what I run. My car wasn't/isn't a full ST2 car anyway. I don't have full aero, fancy suspension and I run small tires (255s at the time). Last time I ran ST2 at VIR I was turning 2:04-2:05s on scrub 255 A6s vs. De Salvo and Wally (ST2 C5Z with full aero and 315s etc.) running '02s most of the time.

Just look at how well the Boss did at the runoffs in SCCA T1 this year.

when ive been on the track with chris and george winkler this season they have been on pirelli or hoosier or toyo slicks. theyve been running aix at the time as well.

I think you may have mis-read my post. I did not say lower power, I said low power. By low power, I mean stock-ish engines. ST2 (and AI too for that matter) does not require a costly engine build. You can get there with a stock LS long block.

I've got a good comparison from my own experience. From what I've learned the C5 platform is far superior to any of the pony cars.

This past April at Road Atlanta I ran with NARRA in GT3 (8.5:1 power/weight). On Saturday I ran my AI car, and on Sunday I drove a bolt on but fairly stock C5Z. I was blown at how good a Corvette really is. We tuned some more power in my AI car to meet GT3 rules. I don't remember the exact HP numbers, somewhere around 350 to the tires. I ran 315 R6's all the way around on both cars. My car has full aero and is 200 lbs lighter than the C5 I drove. The C5 had no aero, and was stock expect long tubes, the older phadt coilovers, swaybars and AP brakes. It was still carrying the freakin' A/C bits. I did not push the C5 that hard because A) it wasn't mine, and B) it had a stock radiator and no oil/trans/diff coolers. I ran a best of 1:32.4 in my Camaro; and a 1:30.4 in the C5. The Corvette was a full 2 seconds a lap faster than my AI car. Imagine what it could do built to the limit of the AI rulebook, less 200 lbs., and with full aero. It would be well into the 1:2X's. AIX cars don't even run that fast...

FWIW my AI car is going up for sale soon; IF it sells, I'm building a ST2 C5.

I thought this was the car you ran that day?

That wing is a joke. It sits on the deck. The customer put it on for looks. I'm sure it does something, but it's not like the car had a full aero package.

That yellow car pictured above has more aero than any PTA legal Vette that ever ran at RA.

Impressive time at RA for sure. Get on with the build

And yeah that has more aero than what we can run. They won't let us tape up the front bumper coves w/o taking points.

Where has this been put in writing? Or are you Vette clowns stirring stuff up and imagining things. I see NOWHERE that Greg has put this in writing on a national level unless it came out since last thursday.
