What size injectors for a 50-trim??

fmic w/piping, 2g ehxuast mani w/40mm wastegate, 2g o2 housing, 2gmas, 190 walbro, 550cc injectors. that's about it right now.

The Walbro 190 might work. It will depend on the boost pressure, fuel pressure and HP being made. At a base fuel pressure of 40psi + 30psi of boost a Walbro 190 @ 13.5 volts will flow around 38 gal/hr. 660cc injectors can supply around 42 gal/hr of fuel maxed out, so they max somewhat near each other. A really good 50-trim setup on race gas and high boost would be able to max both 660s and the 190 pump though, but most people won't ever do that.

i'm hoping to do pump gas, around 350hp...

I think you are hoping a bit high. 3" exhaust? What kind of FMIC? I would guess 310 awhp on pump.

that's fine. 300would be great. thanks much.
