hey guys i have a big problem with my car..i have toda headers..arc intake with chamber..spoon throtle body...70mm test pipe...full pipe with n/a apex n1..i dynoed my car and it dyno at 206 hp! i saw stock s2k's there with only exhaust that did 220hp.. what could be wrong with my car??? my clutch is sliping a little would that make a big of a difference?? what should i look for if anything??

 

That ARC intake is killing you. Those are known for robbing power while proving JDM bling at the same time. Switch back to your stock airbox or a CAI your numbers will be back up to par.

Also, a number of other variables can skew your numbers on a dyno.

This may include:
tire pressure
tire size
wheel size
x-factor
temperature
humidity
elevation
type of dyno (dynapak, dynojet, mustang, etc.)

With that said, no two dyno's are identical. As long as your power curves resemble other cars with the same modifications, I wouldn't worry about anything.

 

hhmm ill try that next time.. but would that intake give me that big loss of power?? im running 16 rims on my car and the weather was good...hmm

 

The ARC airbox does not help for sure,but to me,it's only a matter of Dyno.
Some read low,some read high.
If you want BIG numbers,go to Church automotive.

 

what kind of dyno did you use..
