Hey guys i have a 98 cobra 5.0 stroked novi 2000 about 20lbs, Saturday i got the car tuned but ran out of fuel pump.. im running a a1000 8-an feed 6- return aeromotive rails, and 1 to 1 reg. bosch 95lb injectors.. my base psi is at 43lbs on the dyno it was climbing with boost but once hit around 52psi it fell down and tried to climb back up...:shrug: i have a 12 gallon fuel cell now i know the easy thing is to figure is i need a bigger pump but the thing im thinking is if i go to big then im going to be recirculating the E85 so fast that there is a chance to either boil or have issues with vapor lock:fm:
I need help i got another appointment just don't no what to do because its a e85 daily driver

PM 04Sleeper he is very good with E85.

Set your base pressure higher maybe? Whats your duty cycle on the injectors?

a local drag setup evo makes ~800awhp on a mustang dyno with twin wallies on e85, with the same sized fuel lines.
