Running down the highway at 3000 never bothered me and I know the engine doesn't mind in fact it really likes to cruise at 3000 and seems to really smooth out at 3100 and seems really happy right there.


Gus I think it has alot to do with the exhaust system, but road noise and stuff like that come in to play also. My car is great at 2400, fairly annoying at 2800 and over 3000 is miserable. I'm looking at quieter turbo mufflers, and maybe tailpipes.
Last night's the first time I really laid into this car for an 1/8 mile type pass and it is much quicker than I ever anticipated, I'm dying to get some aftermarket axles and drag radials and see what this thing can do but it may never happen as I don't want to put a roll bar in it.
