Probably anywhere from 135whp to 145whp depending on your engine's state of tune. I ran 135 with POP charger, custom exhaust and UR pullies.

Here's a good page on SE-R.net with a nice graph of dyno runs to give you an idea.

Sorry whp=wheel horse power

I only ever talk about wheel horse power because that's what really matters. Adding the 15% to get crank hp is really just an estimate.
