That's similar to a RSX type S. And on a RSX type S I think if super charged/ turbo'd it can reach up to 290 Horse power.

Absolutely ZERO way to tell. Depends on other mods. Depends on boost level of supercharger. Depends on octane. Depends on YOUR driving ability. You could have a 1,000hp car, and never reach top speed, because of bad driving. Also, you don't have 180 horsepower. The engine does, without restrictions. Minus drivetrain loss, and the rest, and you're down to around 140. At best, and assuming you do nothing else with the engine but bolt the supercharger on...expect to see around 180-190 at the wheels. Maybe.

the person above is right pending on ammount of boost desiring if you can only hit 135 on 180 you will need a fine tune as well my integra was able to do that at 145 hp... so you need to work on your driving=) superchargers add what 30-40%? not familiar with superchargers according to some math 40% of 180 = 72 hp increase ( hypothetically) ergo 180+72 = 252 bhp but you lose some at the crank so i would guess maybe 220-230 max again pedning on your other mods, driving abilities, tires being used there is no way to tell after all the money you spend on the supercharger you still need to get it tuned

It depends on a lot of things, namely the boost level you're running her at, and all other modifications done to the car. If your car has a governor, you will need something to eliminate it. Greddy offers a Speed Cut Controller, which is available through most aftermarket superstores. Here is one I found that was particularly affordable
