new dyno numbers

[bailey_57]

ok long made short, last time i had my car on the dyno it had the e-cam ported e7's and performer rpm intake and put down 241hp/280tq to the ground my max horse was at 5250 rpm. since then the only change i've made is to the edelbrock performer rpm cylinder heads, 1.90 of course to clear stock pistons. anyway the first run which we backed up put out 266hp and 287tq, this was slightly disappointing especially since my peak horse was at 5250rpm still. we adjusted the fuel and i took a turn out of the fpr(stupid me broke my fuel guage so i don't know what pressure it is at, but we made back to back to back pulls of 283hp and 303tq to the ground. i'm very pleased to have put the heads on. my peak torque moved to 4250 from 4000 and peak power from 5250 to 5500. i think the heads being the rpm version should make power well to at least 6000. so, not that i'm not happy, but do you guys think i'm cam bound or could it be something else. by the way i'm still running stock injectors which i assume to be ok since i was able to lean it down and move my power up or is that a bad assumption. oh and on an off topic note the car ran a 12.70 @111 mph on the quarter mile simulator. isn't it great when your brother in law owns a chassis dyno, lol.
