I'm proud to say that I've finally done a ton of testing with street driven Z's and raised redlines. 7800-7900 on a completely stock motor that's beat on everyday and it hasn't had a single failure.

I also worked on 1slowZ's car and we revved that thing to 8700 every single day and for 60+ dyno runs (the rev limiter wasn't working as intended as I had it set to 8300 but it was revving higher. That car has JUN cams, stock VVEL and again, no valve float, no cracked crank, and no issues at all.


Cars with upgraded oil pump gears will do 8200 all day just fine, but keep in mind this is strictly for daily driven Zs and not a track car that sees all of it's mileage at WOT and redline.
