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!

Set em about .021 and forget it. I am not a fan of blowby either and the wider you open the rings the more blowby you are gonna get.

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!
