I suppose we'll see.
My car is already at 170whp, from 159 starting, with just a downpipe and axleback.
I expect intake to add 3-5, and headers to add 10. 183-185 whp... (the car is on the dyno right now). After a tune, who knows, maybe 190-195. From there, some simple things like pulleys, lighter suspension components, etc, and it'll be at around that level.
