if you talk to Rick91gt, he had 4.10s in his dads cobra with the blower. he will know more stats than me, but i was shocked when he told me what times/mph he was runing.... in a good way!
hummmm....how do you even race your car at the track without a tach?!?!?! its sorta like the most important instrument at the track!! I know what my car sounds like at high rpm too...but i couldnt tell you the difference b/w 4900 rpm or 5300 rpm...or even 6k rpm!! The limiter is set from the factory at like 6250 and im pretty sure you would know it if you hit it!! I have 3.73's too and im tachin about 5k going through the traps...E.T. prolly around 14.5....till next spring that is!!!
