[QUOTE="SnakeBoostE85, post: 15757868, member: 160175"] Well I know my solution is not the safest, but I can absolutely attest to the benefits of cooling the fuel down to basically ambient temperatures. Its pretty amazing. All my drivability and hot starting issues are gone. I'm also getting much more consistent AFR's. I also had tweak my MAF transfer table a little. In theory, injecting cold oxygenated fuel into my intake is essentially further cooling the charge hitting the cylinder. When I first installed my whipple, injectors, big pumps and switched to E85, we tried to set my car up returnless, but the AMZ1 computer couldn't keep up, the fuel pump wouldn't respond fast enough and it would go lean. So we just said screw it and installed a return line and pressure regulator. While their is certainly more plumbing, its a far simpler system from a computer stand point. I wouldn't go returnless on an AMZ1 making 700hp. Maybe its possible, but it didn't work for me. If I ever install a stand alone ECU that can properly control fuel pumps I would definitely re-consider returnless. The AMZ1 is a piece of crap, its slow and not reliable for controlling returnless pumps IMO. [/QUOTE]
