Would this be enough fuel??
well this winter im going with a gt35r, woohoo, from RPM performance from the land down under. I only wanna run 12lb this summer or until i have enough to put some big numbers out on the dyno.. My question is if i have bored out 850 to 1300 from rc enigeering and keep the 550's and have a walbro 255, will that be enough fuel to only run 12 psi. I plan on daily driving her in the summer

I would think a 550/1300 would be more than enough to run a GT35R up to 14-15 psi, depending on how high duty cycles you are willing to run. That being said, if you don't have to worry about emissions, it would probably be better to just go with a 1600s in an aftermarket rail.

Hooray For Boobies!!!
My fuel setup is close to yours. I run 14 psi and sometimes more, 17psi. I see at most a duty cycle of 89% (which is high and close to the safe limit). I have also bumped up my base fuel pressure though.
I will move to 850's and 1600 when I upgrade again, just to make sure I have way too much fuel. But you should be ok at 12 with that fuel setup. I would pick up an aftermarket FPR and a gauge also.

r85 blows a hell of a lot more than a 35r

550/1300s should be good for 390-400whp. everything has to be in check though. i have 550/1200s and i ran out of fuel at 13.5 psi and 335whp. i believe i have a fuel pressure problem though and i need my 550s cleaned, they have 80k on them. rewiring the fuel pump seems to help most people. i plan on doing that myself. also chalies7 sent you a pm....
