Running 8psi
Do i need a boostdependent fmu running 8psi? My fuel setup is this: rc 440cc injectors, apexi vafc, b&m regulator, and airtek inline fuel pump. Can i run 8psi safely with this setup? thanks

Re: Running 8psi (D-SPEED)
y does everyone just go around saying get hondata. I know i need hondata. I dont have the money yet. I was just wondering if i could boost reliably at 8psi with that fuel setup.

Re: Running 8psi (BoostedSi)
Yes you will need the FMU! It will raise the fuel pressure when you go into boost. If you just run a base fuel pressur eand run 8psi. you can kiss you motor good bye. Also, when you get the money, I would suggest getting Hondata.

Re: Running 8psi (BoostedSi)
Yes I would get the FMU. Get a lower ratio though, like a 4:1. Then use the VAFC to lower the fueling as the boost increases. If not I think it will be very rich during boost. If you have the VAFC setup correctly, it should run reliabley.

Re: Running 8psi (Bryson)
Its vortech. I could've sworn its was a 12:1 disc tho. I could be wrong. Wut disc do the drag3 kits come with? And also can u buy just the discs if i did have a 12:1?
