well...almost stock ive got magnaflow cat back but thats all...wondering if these were good numbers for a dynojet...it was about 45 degrees that night.http://i288.photobucket.com/albums/ll161/jbevill1987/dyno.jpg

yea those seem too high, as in someone played with the dynos load.

With a standard 15% loss from the crank your looking at 340 bone stock. Seems most of these cars lose more than that though.

Could be one of those infamous "Factory Freaks". They do happen.

yeah I think their kinda high too take it to someone else to see if the numbers are close then you know if you have one of those factory beasts

although it could have something to do with the 45* 's most people dyno in temp double that because they are in a non ac'd shop.

If you look back here three years ago (that's when I first became active here), guys were talkin' mostly 320-330 RWHP for stock '04's on Dynojet. I was about 350 (SAE corrected) with tune and headers last May (pre-maggie) on a Dynojet.

Sure makes you wonder how consistent these darn dynos are. :helpless:

Mileage? Brand and weight of fluids? Original owner?

What gear do you guys run your cars in on the dyno? I run it in 4th, anyone doing it differenly?

03-27-08, 08:45 PM
Norm I run mobil 1 synthetic 5w-30 & the old girl just now creeped over the 30k mileage mark.
Skull i run mine on the dyno in 4th too... i think we have to in order to have the correct gear ratio or some nonsense that i don't understand haha

03-27-08, 08:50 PM
You run in whatever gear is a 1:1 ratio. In our case, that's 4th. (BTW, 5th and 6th are overdrives.)
