Piston Ring Gap for 3.905 Wisecos Kinda curious what everyones running. Pistons came with Instructions that stated for mild boost gap rings 3.905x.0050 which gives you .019 and of coarse you have to gap second ring bigger. Really dont want a **** ton of blow by and I've heard peple running .026-.032. I'll be runing about 15psi boost. Any advice? Yes I've searched. Thanks!

Yea I was kinda curious what people were going to say too.. So many different opinions. I saw some like .032 and .036. Lil much in my opinion. Wiseco said
Street Moderate NOS/Turbo- .0050x3.905=.019
Circle Track/Drag race- .0055x3.905=.021
Drag Race Only-.0060x3.905
and so on.. I was thinking .021 is where I need to be also.

You have a lot of Blow By? What kind of PCV system you running? catch can? But your also running E85. Wish we had it in southwest Oklahoma. Kinda miss my hometown Albuquerque!
