A few months ago I took my '10 WRX Premium (not that the premium matters) to Snail Performance for a dyno day.
After 2 pulls. The numbers seemed rather impressive, almost too good, for what I thought was generally stock. I bought the car used from a local dealer back in march and it seemed to have a few little things done but overall everything looked and felt stock I guess. I have included a copy of the dyno graph for numbers.



Current mods that I know exist:
- SPT CBE
- SPT short throw shift
- steel-braided brake lines.

My question is, what could I be looking for that could pull about 60hp to the wheels from a stock setup. Travis says it's a Wednesday car, but the more I think about it, there's gotta be something I'm missing.

One going theory is perhaps the engine has a tune, but does the dyno pull graph look like its been tuned?

 

Have you looked at the injectors/fuel pump? Maybe a lightweight pulley?

I wouldnt be surprised if it had a tune on it.

 

Checked the pulley, looks stock, as for the others, haven't checked.

Its possible it might be tuned. Does the map give any indication that its been tuned?

 

Ported exhaust manifold, injectors, pump and a tune would net a fair amount of power, but would be relatively "hidden". Easiest way to check for bigger injectors would be to pull the tune and look at the injector scaling.

 

Thanks Rob. I think at some point I may hit up that one tuner guy from sac.
