Can this run e85

Asked by: Wink
The Injectors in the Holley Sniper EFI system are not rated for E85. The system is rated for unleaded fuel only. I have heard of some racers who run E85 with the Holley Sniper System at the track but must flush the system with unleaded gas when finished for the day.
