What fuel requirements for X-charger with XS intercooler?
Guys, buddy of mine is putting an X charger, XS intercooler, and air intake on his Speedster 150 jetboat (basic 215 sc/intercooled motor).
My question is, what size injectors will he need for this setup? I think I read Jerry thinks 42s may not be enough. Should he go with 50's?

That or another ECU ... the stock ECU is calibrated for 38s, it will run fine with 42s, but not with 50s ... way too rich. If he wants to keep the stock ECU, then the RRFPR is really the only workable option.
Truth is we know that a Green Wheel or a Riva S3 wheel and 42s works fine ... but we don't really have much data on the AFR with an IC, 42s, and the X charger. So if he wants to use the X charger he is in somewhat uncharted water and the RRFPR is the safest option.

So he can keep the stock 38's and get a RRFPR?

Or an AEM F/IC and whatever injectors you wanna run (up to 79#ers). . .
