Dyno Numbers *PICS and VIDEO*

finally made it to a Dynojet for some numbers. a local speedshop had a Dyno Day today.

Power Mods:
-K&N FIPK
-Ported and Polished FRPP 70mm Throttle Body
-Ported and Polished C&L Plenum
-Steeda Timing Adjuster at 14*
-MAF Screen removed
-UPR O/R X-Pipe
-Mac Flowpath Mufflers Dumped

plus 4.10 gears, which actually reduce power on the dyno.

you can see at the bottom of the dyno sheet the humidity was 79%

View attachment 386890

and a question: why does the tq dip from 2500-3200 RPMs? any ideas?

How does the a/f look in that area?

 

[DerekStangGT]

i didnt get a/f with the pulls. i was the first on the dyno and they gave me the "we didnt have it set up yet" BS

 

[CobraRed_96_GT]

ouch about the A/F, thats prolly the culprit, given a more steady line you prolly woulda seene some slightly higher #'s, good #'s none the less man

The raw data will have some peaks and valleys and the software tries to smooth it out. Your picture is chopped and I can not see the upper right hand corner where it will tell what smoothing was used.

smoothing: 3

 

[Stan Weiss]

I believe 3 is in the middle with zero not smoothing and 5 max smoothing. Even for smoothing there still maybe of few small peaks and valleys.

Nice #s Derek! Heck, you beat my cars old #s! I made 248/284 I think with almost every bolton! So your definatly doing very well .

And as others have said, your AF probably dipped, or your computer pulled timing due to a momentary increase of tempature seen by the IAT. If you want another run goe to the guys at maxwell dodge off of 620, right after you exit off 183. Gives AF and the guys are really friendly...they will let your car cool between runs for basically as long as you want too!

thanks cody. from what ive seen, the 99-00 GT's dyno a little stronger than 01-04. not sure why, maybe the T-45 losing less power??

mine made 241/282 but it wasnt completely warm, and mad 236/274 the previous pass... had mine been warmed up all the way im sure it woulda put down 250/290... btw thats with my stock manifolds/prochamber/weldinflows and 4.10's and 17x10.5" whells...

show me the dyno sheet and i'll believe your 250/290 claim. until then, its just speculation. i didnt think bench racing was possible even with a dyno
