Jeez, what's with you and Shawn! Shawn is now looking to get rid of his TTA too! Don't get rid of it Pete, you'll just be looking for another one in the coming months when the track re-opens lol. Besides, I'm looking forward to running you sometime this year, and, before you say it, I too have the wife, the kids, the mortgage; first and second, but I'm running and having fun regardless, and that's that (Rob lowers his head, and looks around to see if his wife is reading this while being typed lol)....

Re: How much boost…

I can report that my 1984 stock bottom end is down in the high 10s now and that is with a BAD 60 feet time.

60 foot - 1.827 s
1/8 mile - 7.245 s, 169.85 km/h ( 105 mph )
1/4 mile - 10.862 s, 216.38 km/h ( 134.5 mph)

I don't have a video of that run, but I have one of the previous one.
The differance was an even worse start.

60 foot - 1.995 s
1/8 mile - 7.549 s, 167.11 km/h ( 104 mph )
1/4 mile - 11.295 s, 214.11 km/h ( 133 mph )

(Right klick - save as)

The engine is making power to go low 10s with a good start.
With the 4L80E transmission, turbo and other stuff the Corvette is probably at least 130 pounds heavier than stock and I filled the tank before going to the track. I am not skinny myself, about 280 pounds.

I think the stock bottom could survide high 9s for a while.

According to performance calculators a 134.5 mph trap speed should have an ET of 9.96 seconds.
