I might be slow but the 03-04 cobra piston is 8.5:1 comp. due to the boost app.You will lose a full compression point with these pistons.That will calculate to about 10% hp lost for each point of compression.
No that won't happen...the Cobra heads are @ 53cc combustion chambers where the PI heads are 42cc so compression will stay the same. The 03/04 Cobra piston is a 17cc dish and thats what a stock PI piston is.
