Not sure what each extra pound of boost is worth in term of HP but this was more than I was expecting on this old car.

You will probably see roughly 12bhp per psi of boost.
My car with a few differences made 260/260 at the wheels at 14psi also. This was on a DynoJet which may account for the difference. The Vitesse stuff works very well though, the AFR on the chart is the out of the box tune. No changes made at all. Basically 11.6-11.8afr during the runs. The noteworthy..
Stock 26/6
LR Stage 1 head
Vitesse MAF with 72lb injectors
Full 3" exhaust, no cat
Tial dual port
Here is video from the dyno day, the wastegate is dumping to atmosphere; thats why its so ungodly loud.

Hoping to see atleast 325whp at 15psi in the next month or two. Many changes since the last time i dyno'ed it.
