What was your trap speed?

Going from the top time for a stock car in the 1/4 times thread (12.938@108.31) and the curb weight of a base sport (3232lbs), the LRT calculator for getting hp from mph and weight spits out 331 hp. The other two methods are described in the article as being less accurate. That's why I posted the specific formula for the one that was closest- hp = (mph / 215.39)3.3135 x weight (lbs)

So just a cat back?

The formula feeds you crank hp, so you would need to add back in the drivetrain losses to your numbers.. I checked it against times in the 1/4 mile thread and it was close.

I thought we were all showing SAE which is why my numbers are lower, but here is STD. My SAE numbers are in my sig.

Stillen headers are shorties and make no power. They're a waste of labor. Either long tubes or stock manifolds if you want power.

Stillen stated that with their headers+hfc combo added with thier pulley and exhaust you should achieve 320-340whp with a decent tuner. I already have a full cbe and gen 3 longtube intake......I would add an uprev tune.

Think its possible?

They are the only ones to have success with their headers.

Some people here have tried them. The only people who have shown a power gain with shorty headers are the same people selling the headers.

No tune? I wouldn't expect that much you got without a tune. With a tune its probably a little low.
