Correction factor if any, type of dyno, and what gear did you test in?

Thanks

Dyno jet results with awd traction mod on...453hp and 432lb ft.tq @ 5700 rpms!!! DR Heads,Comp Cam 268,BG stage 2 Flash,Kooks Headers, Volant CAI,Magnaflow Cat Back,Phenolic Spacers, 180 Thermostat,and 2600 APS stall was also good for a 12.31 @ 112.4 with a 1.73 60' am now getting a turbo kit fabbed up at Tune Time Performance which we are hoping for an 11.2-11.5 @ 4-6 psi and then maybe a 75 shot to punch into the 10's by the end of July...modding is a disease...help!!!

Wow that's impressive. AWD or RWD dyno? What gear did you dyno in? Any correction factor?

I'll also add you to the ET list. Anymore info on the run, track, weather, etc.?

Thanks, you're giving us some N/A hope.

The number for 06 S/C as follows

Power 474.78HP at 5800RPM

can anyone tell me how to disable the front wheels for a dyno run no one seems to have a workable answer. When the fuse is pulled the engine wont rev more than 2700 rpm.
any help is appreciated. I go back to the shop on friday and would love to run it. I just had a nitrous system installed and would love to get some numbers.

Pull the ABS pump fuse then disconnect the transfer case plug (located on the drivers side of the transfer case). When you start her up on the dyno after getting it centered, you have to AutoStick it through the gears as quickly as possible. Otherwise it will get stuck in 2nd, which requires you to key cycle (off/on) and try again.

It's always been my goal to hit 400rwhp/rwtq SAE with the stock longblock (untouched heads/cam/shortblock) in our Jeeps, and today I became the first to hit the magic number.
The combination of my Stainless Works 1 7/8" longtubes, paired with their straight through (drone free) mufflers, BWoody's CAI and ported/coated manifold, and a CMR tune from Dave @ B&G is undoubtedly a winning combination.
Next week I'm going with off road mid pipes and having Dave further tweak the CMR tune to see if we can't hit 410-415rwhp/tq.

I'm one happy SOB right now!!!

Congrats Andy!!!

Awesome numbers...something to look forward to. Thanks for the input everyone. Nice forum to learn from..:D
