Hi Folks,
Bought my wife a vette for b’day in april. 04 coupe, A4, torch red, it’s a beauty. Took it to NJ to a wedding. Rpm seemed a little high on the interstate. When we got back to NC I looked a the car a bit closer. At the dealership nothing seemed out of the ordinary except it had a cold air sys added. She had 10 to choose from and most had some kind of c/a added. It’s a vararam. Looked at the diff. 3.73’s. Went back to the engine, WOW, AFR 205 heads. The MAF is from an 01 Z06. Apparently, no cam, no manifold and stock exhaust. Verified by National Speed. I have put 295/35’s on it. 315rwhp 324trq. Do these #’s seem low? One issue I do have is that it does not shift under wot. Just bumps the rev limiter. Let off it shifts. Don’t know what the previous owner was thinking but I’d send him a thank you note if I could find him. Have seen the flow #’s on the heads and the FAST 90/92 (is this the holy grail of intakes). Are there graphs or tables for injectors? U/D pulleys? I have been reading in several places and there are many things to learn about fine tuning an LS1. This will be the play toy ’cause there is a GT-1 Z06 in the future. The vette guys said the F-body guys were head of them in the power producing dept. so I’d like to here from the collective F-body brain trust.
