Has anyone have experience with vito's super stock pistons for the banshee? Is there a noticeable difference in power? Also is this HP increase due to increased compression or for other reasons.. Another question is What is the highest compression you can run pump gas (93oct)domes for cool heads... 21cc..20cc? Since I have to get pistons and cool heads, am I better of getting regular pistons with higher compression domes on the cool heads, or vito's pistons with regular compression? SORRY ABOUT ALL THE QUESTIONS BUT I REALLY NEED TO KNOW BECAUSE IM ORDERING THE PARTS tomarrow.. THANKS FOR ANY REPLIES..

The increase in performance doesnt really come from added compression with Vito's Superstock but from the fact that they are "ported" pistons.They simulate a mild port job, the crown has been machined on the exhaust side and therefore alterate the exhaut timing, yes they do produce more power than stock pistons or regular Wiseco pistons for that matter is it 8hp i dont know...Are they worth it?...Id say yes they are, if you are running unported jugs that is but if your cylinders have been previously ported do not run SS pistons unless your engine builder advises you to...
