[QUOTE="Beffastang, post: 12778933, member: 123909"] Either one is a good choice I'm running a 3.4 whipple crusher with 25lbs of boost on my car on E-85 I'm currently running the BR7EF's gapped a .020 and my car runs perfect. The BR7EF's are a one step colder burning plug than the TR6's. I had TR6's I'm my car with my ported eaton and they worked perfect.when I put the whipple on my car with them in gapped at .028 I had spark jump so we put the BR7EF's in and gapped them at .020 and it ran perfect. For your set up I would stay with the BR7EF's and gap them at .020 and I guarantee that it will run perfect. We also could of gapped my TR6's at .020 and they probably would have been fine, but the BR7EF's come pre gapped at .024 they are ment to have a tight gap and they are a colder burning plug so it just seemed like the better choice to go with them.
