The 150hp at the crank may only deliver a usable ~120hp to the wheels (I'm guessing). An unknown and variable percentage will be lost in the transmission and axle.

3800lbs and 112mph shows about 410hp at the wheels. Add the guess of an additional 120hp (530), and you could be around 122mph.

Every 10 hp increase is approx. 1 mph, but only till you hit a certain point then gains are less.

So I would guess 10-15 mph increase and a drop of approx. .75 - 1.0 seconds.
