Default I can only race from 50mph

wheels / tires just can not take the TQ below 50mph on the gas (75hp), I am going to the dyno soon to check A/F, any one think they know how much HP and TQ it will make?

Dale, at what speed does your car hit redline at in 1st & 2nd? there's been some talk that the SS's have 3.29's not 2.93's like the GXP, my car hits 48-49mph (1st) & 100-101mph (2nd) and I have no clue what it will Dyno at, but I'm anxious to see if we're underated or not..

Your # of 48 in 1st and 100 in 2nd is on track, but I think that the tire size and wieght of the SS off set any gear it mite have over the GXP's. My 1/4 # with only 500 mile on it are slow (mph) I changed the oil at 3000 miles and it now feels like it run stronger... oh do you have 17's or 18's on yours? And the gas kicks butt..

Hey, Dale did you get your conformation e-mail from clubgp?? Are you using AOL?? If so look into your spam folder for the conformation e-mail as aol will think it is spam.

Dale, The GXP's have 18's (255/45's up front & 225/50's in the rear), I left word with one of the key engineers that is retired now, but helped develop the GXP, he said as far as he knew, the SS & GXP are powertrain identical, which I believe is also correct, check Club GP for the outcome, I see you finally got in over there..
