I'm gonna put a higher compression piston in my Wolvy this winter, and I was wondering which piston you guys would go with? I am running 10.5-1 .020 over Wiseco pistons in my H-D Shovelhead. I like them well.. look to be well machined and gave me a strong increase in power. BUT...I have heard a LOT of good things about J.E. pistons... I see a lot of you guys running them. Let me know what you guys think about either brand...GOOD or BAD

 

I have ran both in the raptor...........but have had no prollems with either..........
but the JE piston holes kinda scare me........considering I'm running a JE right now.......

 

Big Scary- I am with you. Looks like JE are prone to fail. I have gernaded one ( it was lighteen beyond the max) but i have seen others that have given away are about the give way. Not impressed with the wislico either. Looks strange next to a JE with the skinny skirt. I did not like the dome area of the wisleco. Custom made Ross piston are the future of raptors.

 

I don't here any good things bout Wiseco Pistons.

If I were you, I'd go with JE.

 

JE is a bad company they dont like to make up for there mistakes they sent me a chunked up piston and tried to pin it on me. Wiseco is where id get it from.
