Dynoed the Formula yesterday
Dynoed the Formula yesterday Well I was pretty happy with the results I got. I dynoed on a Mustang dyno and the temp was about 65-70 degrees. I did 2 pulls that the second one was the best. My a/f ratio was pretty smooth across the rpm band. It ranged from 12 to 12.3. The torque curve was almost flat all the way across. See the numbers below in the sig.
I was the only GM that dynoed that day because I went up to the dyno with a local Mustang club. I wasnt planning on dynoing just they had an empty spot waiting for people to show so I threw her up there. I work with a couple of the guys that dynoed both have an 2002 GT. One with k&n, C&L Maf, 75mm TB, X-pipe, catback, alum driveshaft and 3.73's only put 241hp to the wheels. All that money and still only got those number <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> j/k I know, I know the LS1 has more cubes.
There were some impressive Mustangs there. There were 2 Stage 3 Roushs (?sp) with the roots type blowers that put 34? to the wheels. There was also an 03 Cobra that had every bolt on k&n, Intake tube, TB, pulleys, x-pipe, catback and I believe the Lightening blower pully that put out 391hp <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Finally the 2 most impressive was a GT with all forged bottom end w/ Vortec and aftercooler running I think 12 lbs. making 396hp and also a Stage 2 Roush with a Vortec that didnt dyno that day but puts out 523HP on a dynojet dyno. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
I asked the owner about the difference between his Mustang dyno and the Dynojet dyno. He said that his dyno will show about 10% lower than if you dynoed on a Dynojet. Sounded right to me seeing that would make the all bolton 03 with 440hp.
That would also me mean that I am making <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" /> 335 HP and 346 Trq with just a lid and catback. Sorry bout the long post. I'm just still hyped about the whole thing.
