The Edelbrock Perfromer X kit comes with an intercooler. The 177hp number is at the wheels on a chassis dyno. The stock 00 Civic EX D16Y8 is rated at 127 hp at the crank, on an engine dyno. On a chassis dyno The Civic stock makes 105-107 hp at the wheels. So the power increase is 70 hp at the front wheels at 6.5-7psi. If you compare proportionally the chassis dyno numbers to the engine dyno numbers 177 hp at the wheels is 210 hp at the crank. Comparing by adding the power loss stock to the turbo "at the wheels" number the power would be about 197 hp. I would say that the power of the turbo kit at the crank would be between 197-210 hp.

Edelbrock is finishing up a D16Y8 engine right now to run on the engine dyno that will be able to handle as much boost as the Performer X will put out. When I find out the power numbers the kit makes at different boost levels I will publish that data. Soon Edelbrock's Open Track version of the Performer X kit will be available.
