Hey guys, i know i know YES megasquirt is the only thing BUT
My friend has a slighly built engine.
We got toga engine bearings and millenia s rods installed on DE pistons. Klze heads.
Can anyone tell me around how much psi that can take before it pops?
We have aem wideband and all the goodies, we just need to know a safe level, example.. safe leven on a stock ze is 5 psi, but whgat about this light build?
Slightly built ze with de pistons?

not about psi hec... its about how much power your making....

Re: Slightly built ze with de pistons?
duncan hit the spot on that one. and its Its all in the tune. I really don't think the millyS rods will make it be able to make more power. Yes the rods are a bit beffier but its all in the tune. I personally think when a ZE bends/breaks a rod its not because of too much power its from a bad tune. On almost any engine the rings and or ringlands won't take the excess pressure you get inside cylinders on a boosted engine.
This also sparks up one other question. How is he running millenia s rods on klde pistons?

Re: Slightly built ze with de pistons?
The other thing you could do is calculate your compression ratio (S rod length, DE piston height, ZE crank, and whatever else, what is it now?) , and see what motors with similar numbers are pushing. That will help you a lot with your tuning, too.

LOL that never even crossed my mind.... it is all in the tune but 350whp is really pushing those DE pistons.. some ppl have run even more power than that but they also had one hell of a tune and eventually blew the engines
or just compression test the engine and see what its actual compression is which should be a standard DE compression. and comparing cars isnt the greatest idea there so many varibles like piston crown thickness, material, engine size, ring lands and all

Well he took it to the machine shop, they had to modify the wrist pin and installed it on the rods.
