a close friend of mine just got his b16 in his crx, with the help of some friends we installed a clutchmasters stage 1 clutch with their flywheel which is at 7.5lbs

now after 500 miles of going EASY on the clutch/fly (all city miles btw) we finally decided to take her for a hard drive, to my shock it took FOREVER to get to redline through all gears, i mean my stock drivetrain b18c revs MUCH quicker, and this has got me thinking all day, on wtf it could be

keep in mind, he is running stock HF piping which is well embarassing, could this be restricting his revving ' that ' much?

any help is well appreciated, thanks in advance my R brothers

 

lalalala..........
