New PB at Irwindale 1/8mi. 2-10-11 Went to the track tonight to see if the tweaks I made to my exhaust would translate to the track. Im running 3" Dynomax bullets to dual 3" pipe and x-pipe from the header collector back. I ditched the chambered mufflers. I only got one run in. Tires were cold and I was afraid I'd spin them so I launched just short of 2Krpm. Ran a 7.07 @ 98.73mph. Thats 0.21sec and 2.12mph difference vs. my old exhaust setup. They took my wristband and reminded me I have to start shopping for a rollbar. Lol.
Car is an LS1 with TFS 215 heads, (similar too)MS3 cam, FAST90, Yank SS3600, 3.42 gears. All motor.
Old exhaust setup and prior PB
10-16-10, 5:19pm 60*
R/T .575
60' 1.643
330' 4.729
1/8 7.28
MPH 96.58
New setup w/ Bullet mufflers, new PB
2-10-11, 5:48pm 61*
R/T .592
60' 1.584
330' 4.585
1/8 7.078
MPH 98.73
The car seemed to pick up hp all across the board. 60' was 0.059 faster, 330' was 0.144 faster, 1/8mi was 0.21 faster and the car picked up 2.15mph. Not bad for an exhaust mod.
