Ive been going back on forth on doing a fuel system for my GT500 since I live in Arizona. Per state law, we only get what amounts to E54. Ive decided that I should bite the bullet, as the 91 octane out here wont support the blower upgrade I want to do. (VMP TVS with 2.4" upper and 15% lower).
Since all we have here is E54, can anyone tell me about it and how it compares to E85? I heard E54 has 90% of the anti-knock and octane rating of full on E85. Is there a limit to its performance and the amount of boost I can run on E54 versus E85?
Since there's more gasoline and less ethanol, would I need a return system or could I upgrade my fuel hat, pumps and injectors and stick with returnless?
