I am running twin 70mm turbos on my 363 sbf and am just wondering if my current housing are too small. They spool very fast and just thinking they might be causing excessive back pressure, what are you thoughts?

hard to say on a motor that "small". does it have a good flowing head/cam? you probably could make some more power with bigger housings but you'd be best off actually doing some calculations or talking to a supplier/manufacturer. how quickly is it currently spooling? where does it make full boost?

Heads are AFR 205 renegades, and cam is custom solid roller 656/653 248/252 @ 114.2 lsa, have not built to full boost yet but will build 12# on the brake at 4200 and still ramping up.

More info on the turbo may help. Exducer wheel size, DP diameter size?

But im strongly leaning towards, yes. That is to small.

Its twin on three 70mm turbos, but i think i will just have to fab up something to measure back pressure.
