I have always heard that a 20% loss to the drivetrain is more in line? So, about 80HP loss on the automatic, with a sightly larger number for the manual?

That means 340 - 370 rwhp corrected enginge power for the auto and 370 - 400 rwhp corrected enginge power for the manual.

Same as with our Chryslers we had on several German Dynos! In most cases was the engine power > 10 % less manufactures data.

I have been "running" chevy's for years and the "average" so called loss of HP is usually between 15-20% through the drivetrain to the rear tires due to torque convertor and everything else down the drive line. The stick shift actully is a little less than and automatic.

Please advise!!!!
Thanks

So here's my DYNO. The only MOD to the car is the SLP LM II Axle Back Exhaust. I'm pretty impressed and so was the guy doing the DYNO who happens to only work on Mustangs. He said that it was running very rich and a CAI along with a TUNE would probably add close to 40 RWHP easily. I'm holding off on the TUNE, but the CAI (once the JannettyRacing test comes back with results) will be my next MOD.

Saturday, Oct 3rd. Temp 77', Humidity 38%.

Three runs: 1100 Miles, 2 Oil changes so far.

TIME - 10:34A BLUE Line Max Power = 337.04 Max Torque = 355.64

TIME - 10:59 RED Line Max Power = 344.88 Max Torque = 363.54

TIME - 11:08A GREEN Line Max Power = 344.14 Max Torque = 362.99

Had ADM do my CAI, and tune yesterday. Previously was stock except for the street demon exhausts. Pretty inpressive results I think!

Andy did a great job and has another satisfied customer!

I agree!

Any other work planned?

It looks like everyone is waiting for this test result to buy. Somebody is going to make a lot of money and have a lot of orders to fill!

rforbes · 10-16-2009, 12:08 PM

Naw, probably nothing performance wise. This is my everyday driver, and it is plenty fast enough for me right now. Maybe just a little more bling later.

Only 311 HP was your baseline?? That seems kind of low, but I know dynos vary all over the place.

rforbes · 10-16-2009, 03:36 PM

Andy said that was pretty much the average he was seeing for the L99. Seemed pretty low to me too.

GMRULZ · 10-29-2009, 04:16 PM

ARH 1 7/8 w/ high flow cats, stock mufflers, ADM race intake, Tune.

NHSS · 10-30-2009, 07:23 AM

The salesman filled it with 87 octane... I ran it out, and filled with 93 octane and then drove for a few days like that. Power actually felt pretty good. I then disconnected the batt, hoping for a little more, immediately noticed a power loss. Check out the a/f ratio.... A little tweaking of the a/f and timing seemed to do the trick. My uncorrected was 345 hp with some cool, dry air here. Going to the track tonight.

Mine is with a Roto Fab CAI and an MBRP Cat Back.
