CAMARO6 - View Single Post - Max power capability of the LT4 sc, other adds?

The factory sc has been ported by Kong, but we didn't do the xport. I'm debating on just going to the 2:45 pulley or instead going to a 2.38 pulley and running it back to the tuner with the increased ethanol to check it out.

The tune was done in Phx at 1200' elevation and I live at 6600' elevation so I'm guessing there would be no problem running the 2.38 pulley here as I lose about 2-3lbs of boost but hardly any events up here to run the car.

If I just went to the 2.45 pulley I'm guessing we'd add just 1lb of boost and with additional 20% of e we'd be good?

Tuner has said we now have the capability with the new cam, bigger injectors and upgraded pump to run to 850whp without leaning it out for safety's sake, but what does that do for us performance wise without additional tuning?
