The car is a 89gt with a stock bottom end 302 with AFR 185's and a holley systemax intake, but the cam is a custom grind for a nitrous setup. The car made roughly 330rwhp on the motor. Now the car has a custom single turbo setup with a 76mm masterpower turbo making 6lbs and it made 440whp. Do you guys think thats low or about what it should make? A few people think its floating the valves even though its got competition springs and think it should make more power:??:
How much power?
- Thread starter RCM90
- Start date
that soounds about right, I wouldnt go much higher on a stock block.
I thought that 110whp gain was decent for 6lbs, but others think that there is alot left in it. The car went 11.2x's @124ish all three passes. The tuner told the owner to not turn it up because it would cause the valves to float more?? We talked to AFR and the tech guy laughed about it floating the valves between 5000-6000rpm on only 6lbs, he said there was no way.
We stay around 500whp and nothing over 6500rpm.
