So whats going on here ???

luigi90210 · 09-17-2013, 02:49 PM

im confused

what happened when the motor blew up?
did you retune when you lowered boost from 12psi to 8psi?

Ok so update:

Have GTM shipping forged rods, pistons, and head gasket. Forged crankshaft also otw. Some other misc. stuff also. Hopefully parts will be here by end of the week. Will post pics and new dyno map after the tune. Say a prayer for me, I miss my baby. I be fiendin' for my z!

And 12, imo, is in the upper range of what I would consider a reliable setup with stock internals. Maybe you are lucky, who knows. All We know for sure is that someone else had rod failure at the same boost that you are running.

Someone also mentioned another failure, I wonder what boost he was running...

The amount of boost that's safe to run varies based on what is making the boost, right? 12 psi on a Stillen sc isn't the same airflow as 12 psi on a turbo kit. Maybe we need to look at cfm rather than boost.

whatever boost keeps the a/f ratio in safe parameters?

12 psi is 12psi. Doesn't matter what form of induction u are running.

No, 12 psi out of something that doesn't flow a lot of air is very different than 12 psi out of a huge compressor. If you blow 12 psi through a cocktail stirrer, you're moving a lot less air than 12 psi through a garden hose.

Only if you can produce the air to fill that garden hose

Now you're talking volume of air not pressure. You need the pressure to force the air into the engine. The volume comes from the size of the intake all the way from the air filter through the valves to the cylinder. Am I right? Or am I missing something. Seems like a simple physics problem to me and I'm no physicist.

This is so far from the truth.

Care to explain why 16psi on a T25 turbo makes less power than 12psi on a 16G turbo?

Here is a good way to look at it, when you're fighting a fire, which works better, 12psi of water through an aqurium hose or 12psi through a garden hose?

There is some truth to your statement but you're not taking into account for flow since a bigger turbo will be pushing more air at the same psi then a smaller turbo would be.
