Here's the old JWT700 kit on 93 octane and 25psi vs. the single 7175 kit on it's E85 break in tune w/ 17psi.

Yes it's slower to respond than a smaller twin kit, thats about as much of a suprise as turbo honda having wheel spin from a dead stop.

Whats fun about this though is the cars not even trying... still another 10psi or more to go. With the cars intended use being killing modded Z06's from a roll or other would be highway kings the meaty area of the power band is right where i want it, peak power right at redline and torque that doesn't quit, so i can carry the power through my entire intended RPM range instead of giving up 100ft.lbs of torqe and 50hp by redline like on the old system. The car will start from a roll, be at peak torque, carry peak torque to redline while the horsepower increases through the rev range, and on each shift it will land right back on the same flat torque curve and rev itself back out again.

Will it autocross? Hell no.. but thats not what it was built for. In the event the midrange becomes an issue, theres plenty of room for nitrous to enhance the low and mid range power band. But hey, feel free to pull along side me at 60 and see if you can hang.
