My only mod so far is removing the charcoal filters. I had one run at 417 - I'm told I have a pretty strong car for stock. For comparison those that have dyno numbers with same setup please post.
Keith,
Maybe u can chimp in on my dyno thread I posted especially a/f ratio. I pulled 399hp (CF removed, section1&2+stock muffler, K&N filter). Then after Evo pulley+exhaust, the car pulled 402hp. Then it pulled <400hp after BMC filter installed. I used Dyno Dynamic all on 5th gear (temp 82-92F) I'm ouich:confused2right now...
Thanks.
My recent run against my friends Nitrous M6 (nitrous off) I beat him by 7-10 cars or so.....Gustav was in the cars when we raced...he also has the videos of the race with and without Nitrous (hopefully he will post them soon)
Bottom line - what I am trying to say here is that the dynos didnt show me anything close compared to what I saw in the race.
Keith
Come on Russ its not like you beat super charged Viper or any fast cars like that.I agree with Keith. My car shows only 445rwhp on an archaic dyno, but the races I have done tell a different story.
You would have easily hit the HP peak of 7750 with the 3.91 diff.well, I had them dyno my car in 6th and the only issue was that I did hit the limiter in 6th, but I think the dyno I was on can handle the speeds, it just cut out at 7400rpm because of speed limited
