Question for the tubular turbo manifold guys
I'm rebuilding my twin turbo kit on my V8 RX7 and this time around I'm building tubular manifolds. I was wondering what ID you guys were using for the primaries, and are you pleased with the size? Too much velocity or to much volume? My heads flow 253cfm on the exhaust side with a cam specd for my heads, and I'd like to take full advantage of that if possible. Any advice or words of wisdom would be greatly appreciated. Thanks!
