how big of a TB do you guys reccomend going on a setup with crower stage 2's, I/H/E, V-AFC, & ported manifold?

on a stock TB, i believe (from enquirees with other ppl) 62mm is about the largest you can go.... with highly agressive cams, and the lift your getting the more air in the better i'd assume. But if you do it, get your intake manifold port matched otherwise its kinda not really doing anything at all.

But i think Mugn bores out to 60mm. (stock being 52)

i think its 52mm. i'll check my manual.

But stock on a f22 is 52mm. h series might be alittle bigger.

Stock bore is 60mm on H series engines. RC engineering bores 4mm over to 64mm.

I was gonna say 50mm sounded a little small.
