I don’t know about all that, but I know Federated makes these speed pro pistons.
Just a big circle.
to be fair... my engine has turned over 8k if im not mistaken @lwarrior1016 but yea i drive it on track and bring the rpms up to 7100 at times (usually shift around 6950)
Those carnage pictures were cringe worthy for sure!
And not to help my argument at all but I’ve even heard the guys use them in the circle track cars down here around MIR. OH WELL. Lol I put boost to them and they did not like it at ALL. lol
Wish I could upload the choo choo train steam video of the blow by coming out of the breathers. It was more of a gag than a cringe for me tho when I saw em. Heh.
The pistons were fine, it was the tune..I have seen the same thing with forged pistons.
Have you noticed all the high end Ford/Chevy factory crate engines come with hyperutectic pistons
I learned a TON of knowledge when i built that 18.1comp engine. Pistons were forged, bores were propetly sized, the fuel however was not correct for piston heat expansion. Meaning the piston never fully expanded to running temp due to me running E85 when the pistons were designed for propane. Propane being a hotter fuel.
