FBO E85 OPG result

[Dom1232]

FBO, E85, ported 18 manifold, revved to 7850 pretty often for the past year or so and i missed shifts and slammed the limiter a few times as well lol. Pulled these the other day and they look great! Probably more of a FI worry than anything I guess

There was a video of a guy that had over 1200WHP on a TT stock engine GT for MANY track passes and when he finally tore it down to give it an actual engine build and see how the internals held up the only comment on the OPG was that it had "a little bit of wear but was otherwise fine."

OPG's used to be a MUST for a high revving/boosted car, heck almost a "better safe than sorry' on a stock 4.6. Now its just a "better safe than sorry" unless you are doing LOTS of track work.

did you mic them? which brand? That seems like a lot more scoring than I'd want to see. But I don't know if they went in new in such lousy condition.

Those look pretty rough to me...

They need measurement for sure.

These are factory 5 years old with 50k miles, I genuinely wasn’t surprised there was scoring. Cleaned the housing and threw in a set of boundary
