Help with dyno #'s I have a 2000 SS 6 speed ,
Mods are-
3.73 gear
Lid & K&N
Gran MAF
FTRA
Slp loudmouth
My dyno #'s suck I was wondering if this is normal or below normal?
1st pull 309.7 HP 315.8 TQ air/fuel was at 12to1
2nd pull 308.3 HP 315.2 TQ air/fuel was at11.5to1
These 3's was taken off of a Dynojet temp was about 60 deg outside car was running about 210 deg
What do you think is this good or bad?

<strong> Since no one has tackled this one yet, I'm going to give ya my 02 on it. I've looked at your mods and your dyno #'s and your A/F ration and it appears you car is down on power (compared to other vehicles with your mods) because your a/f is really rich for being Naturally asperated. You should be in the neighborhood of about 325RWHP-330ish + - a few. If I was in your situation I would put the stock Mass-air meter back on (i think your grantelli is making your car run rich) and re-dyno it and get a new a/f reading. You want it right at 13:1 for optimum performance. If it is still rich, I would de-screen your stock one which will lean it out a little more and should put you to where you need to be in regards to A/F.
My 99 with just a lid did 318RWHP & 333RWTQ and a/f was dead-on at 13.0:1 to 13.4:1.
Good luck. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Man dont put so much emphasis on dyno numbers. You are giving up a little bit due to your A/F being rich tune it to 12.8:1 and you will see more power. Honestly your numbers look average to me, #s will vary from dyno to dyno but my '99 M6 put down 305/318 with a lid and cat-back and 330/337 with the addition of LT headers through cats, and it runs like a raped ape. The average dyno number for a stock 98-00 is about 290 SAE (dynojet) so you picked up about 20 from slight mods, looks pretty good to me.
