will i notice a gain with an 11.5:1 compression piston(11:1 stock) on my piped, jetted, and filtered mojave. stock bore*.

 

You bet!

 

I don't think you will notice much if your engine is in good shape right now. I have a wiseco piston and it is bored.020 over and I noticed a slight gain but my top end was tired and I had the valve seats reconditioned and the bore job done and then I ran it. I don't think the 1/2 point will give you much. It definetly won't give you enough of a gain that its worth taking the whole top-end apart. Wait till it gets tired then use the wiseco as a replacement piston.

 

ok thanks for the info.
