I'll ask for input on here since Holleys sucks. Ive been contemplating switching over and running Ignite E90 ethanol , its much cheaper shipped to my door then race fuel . Me and a few buddies need high octane and we burn a lot with a mega truck and ultra 4 car and rockbouncers so we are looking for cheaper options. Ignite claims some large hp gains from their fuel alone. My biggest question is , I can't find info if my Holley terminator efi is compatible with ethanol or not. I see some forums that people run it with stock systems and some go to 120lb injectors but I have no idea where or what else needs to be changed , ofr the ecu will self tune to e90? I'd like to hear anyone's experience or input . A few people have strongly urged against the switch but at 270$ a drum vs. 650$ a drum for race gas there's a significant price difference . Also hp to be had and cooler motor temps .
