F8-DOHC limits tested! Fail.

[Fred]

I recommend you only push about 8 or 10psi down the throat of any F8-DOHC on an efficient setup. I pushed 18psi down mine for about a week with a very efficient setup, and BANG bent a rod in half, then snapped, then exited the block. Fail. Sorry GURLB8, it was GREAT while it lasted, but those rods are far smaller and weaker. No small end bearing, either.

PS, I keep blowing up engines by over stressing internal engine parts, not melting pistons... Anyone that melts a piston is basically to blame for their engine's death.

On the small end, 30 next to forging seam, 31 on it - for f8 rod, and 33/34 for the fe rod, f8 shank is 14.5x20 and fe shank is 15.5x22 + taper to 27 before curving out to big end, f8 are straight, no taper... mm for all units!

I have a plan, stan!
