[QUOTE="biminiLX, post: 16389865, member: 7795"] Thanks Cat. I do plan on trying the 8s this year as we found the limit of TR6s on my brothers turbo E85 Terminator. I think I’ve learned E85 on decent boost and timing let’s you run a hotter plug than gas fuel. The hotter plugs supposedly run better off boost, but I’ve ran 8-9 range on my turbo 427Ws, and never had plug fouling problems. People tend to forget heat range and also don’t realize the 5.8 moved to a slightly colder 7 plug so if you’re turning the wick up on pump gas or race fuel, go to a heat range 8 or a quality NON-projected tip 7 you change more regularly. I always choose non-projected plugs on boosted cars. -J [/QUOTE]
