I built a 03 Mach 1 and made 9xx on e85 through a single MP 4303, but it was maxed out. Just bought a 97 cobra and I am going to twin turbo it and shoot for anything north of 1k, not sure if I am going to go auto or manual. I would like the fuel system to be 1200 (or more) rear wheel capable. What are you guys using? I was thinking dual 4303's (one on a hobbs) but worried about the voltage draw from two when in wot. Thinking about one 4303 with a smaller external such as the .044 or aem 340 designed for e85. Lets hear it thanks in advance.
