hi all, i got a qiuck question, i got a stock 7afe with 4 into 1 headers and a performance filter and 17inch wheels, on sat we had a dyno day and my car made 76 kw at the wheels and 147 nm torque, it makes max torque at about 4000rpm and at max kw just after 4500rpm. there after it doesnt do much in the way of speed, i struggle to reach 195km/h my my friend with a stock 4age motor passes me like i'm standing still, the motor is newly rebuilt, question is why am i being creamed. the car pulls strong up untlill 3rd gear but when i put it in 4th i'ts all show and no go. is the dyno figures about right or not the workshop manual says it does 86kw dont know where the measure it though.

It's sad that my stock 599cc Ninja has more HP than my 7A in its stock form. :rofl:
