Cool Inputs about my fuel setup?

550cc primaries
1000cc secondaries with K2RD fuel rail
Walbro 255LPH fuel pump
Aeromotive FPR

And I have Microtech to tune everything... how much power would this setup be good for? I'm gonna shoot for 330-350rwhp when I get an FMIC... I made 285rwhp@10psi so I think I can get somewhere in 330-350 at around 15psi. What do you guys think? Any inputs are appreciated

On the FD, the 550 primaries and 850 secondaries are good for about 330 rwhp, which puts them at about 85% injector duty cycles.

dont know how much this info helps..

That's cool. I can always decide to move on to a real turbo instead of hybrid if I decide I want more power... W00T!

Anyone remember that website where you type in your injector size and max duty cycle and it pumps out the estimated HP that it can handle?
