MS4 and bolt-on's through a 9"
 

Finally got around to sliding the camshaft in last weekend, and I went to the dyno yesterday. The car currently has Pacesetter LT's, 2 1/4 true duals through magnaflow mufflers, LS6 intake,and a ported and polished throttle body. My car is a 2000 but was blessed with the 241 heads. Also this was through a 9" with 3.90 gears and 17" DR's with 20PSI in them. Also with the air filter in, and air intake was a whopping 101 degrees, and humidity out the roof!(damn Alabama weather) Well I'll let the graph do the telling...

Great numbers man with that rearend and the crappy weather.

Now go get some 11sec timeslip.

Thanks I thought the numbers we're decent. My other 2 pulls were 397, with the same torque. What would be the best way to get the torque numbers up? Without going with a set of heads.

i think you could have done better. try a dyno without the mufflers and 2 1/4 inch pipes.. maybe headers with 18" extensions. I think its restricting you.

Yea I am about to go with a y-pipe setup(duals just make it to hard to work on the car).

ya and i've heard that Walkers dyno spits out low numbers usually. Who did your tuning?
Ya it was really hot Saturday.

Marcus did it. We street tuned it last saturday, and the first pull it showed it was a little lean, but pretty much dead on. Well if thats low numbers I need to go to one that spits out the high ones! lol I was just happy it broke 400. I knew it would be close seeing as how I am going through the 9", and how hot it was. I'm going to try a few little things and go abck around october or november and see what it will do then.
