Hey today the guys at S&R were gracious enough to let have a free pull on the dyno, to get some more base numbers for the TurboTrix tuning session this weekend....

I have a stock WRX wagon 2003 with only an SPT short Ram air intake...

Well my numbers actually were lower than I thought..

Max WHP= 147.0 @ 5658rpm
Max WTq=168.6 @3068rpm
Max Boost not measured probably around 12-13lbs on a stock turbo.
A/F Ratio was right on! Perfect curve readings we great, so not running Rich or Lean.

Are these numbers normal??

Seems kind of low even for a stock WRX I was expecting about 175whp.

I will doing a up pipe and 3.5" TBE no cats next weekend, so I wanted to get a base line to compare to.

Something doesn't seem right. Let me know what you think might be wrong??

 

Sounds about right for a "stock" car. You may have been injesting some warmer air due to the intake and not being moving, but that sounds about what it should be.

The target boost for stock would be about 14.5 though.

 

mine measures in bar's its max's out at about 1.2 bar's. I'm going to attatch the dyno sheet so you guys can see it.

very low numbers. most stock wrx's pull 170-175. that's what ive seen.

 

exactly! What the hell!!
Could it be the dyno is not calibrated right?

I'm not blaming them at .... just wondering if thats possible?

 

Every dyno is different. Those numbers sound similar to what you would get off of a mustang dyno.

 

My car with headers and TBE only hit 251.9 hp and 258.8lbft. Jeff's stock STi hit 222hp and cant remember torque. IMO the dyno is relative and Land & Sea say "the bull stops here" so versus other dynos that always spit out huge numbers to them I say who cares that with identical mods on another dyno my car "should" make 284hp and 289lbft so its not important as long as you see the power gain thats all that matters IMO.

 

realistically a dyno number is best for measuring yourself against yourself. it gives you a change from before to after.

 

a better explanation was never spoken
