Just got my car dyno'd for the first time at Bisimoto Engineering in Chino, CA. They use a dynapak dyno. Here are the charts from my session. Can anyone tell me why the numbers are so low??? This is with AEM CAI and Fast Intentions exhaust on an '04 AT coupe.

 

well, I don't keep up with the difference b/t dynapack, dynojet and mustang dyno.
But you can't really expect to compare it apple to apple with different type of instrument.
So what's the average result you've found from dynapack user?

one thing I noticed your torque curve took a dump after 4500rpm, your AFR went pretty lean after 4500rpm too, might want to pay attention to that

 

I noticed it started off pretty lean but then corrected itself second time. How about the ratio, were we using the right ratio???

 

You need that ratio about 14.5-14.8 to run well

 

dude on a mustang dyno you wouldn't even hit 200 whp. Idk whats up but those numbers are off.

 

yeah man, i agree with gbiker, on a mustang dyno with load applied i have never seen a 5at go below 200whp, yours seems like it will be under 200, fix up your AFR a bit, maybe that will help somewhat.....or get a tune

 

Just an FYI: I don't have a tune yet and with my bolt ons, 94 Octane gas and a 2 degree timing advance I pulled 258WHP and 242 TQ on a mustang dyno.
