[QUOTE="LargeOrangeFont, post: 13776146, member: 22835"] It still sounds like you are assembling this car with a drag racing mentality. Remember the car is going to be at high RPM all the time out on track. It does not need to be revved within an inch of its life to be fast. Where does power start to fall off with your cams? If your redline is 7000 that is only about 123 MPH in 4th. You are going to be spending a lot of time shifting in the infield. If you ever have to shift into 5th the power is going to fall off a lot because of the overdrive gearing. I am assuming you have not swapped in a close ratio 5th gear or anything like that. The car does have torque so you won't have to get every last RPM out of it like you would a miata or s2000. I like to be able to get to 135-140 in 4th. My track car has 3.73s and a 7000 RPM redline but I typically shift at 6600-6700. I run on shorter tracks as well with a top speed of around 120 and there is plenty of power. I run 70% of the track in 3rd gear, and shift into 4th on the straights. [/QUOTE]
