2005 Mustang GT
S.O. Vortech Supercharger (8-9 Lbs Boost Currently)
3:90 Gear Ratio

I am getting a custom dyno tune on Sept 16 and am also swapping the supercharger pully to get more boost. I am trying to get an idea of what most people think should be the maximum boost I can safely put out without hurting my otherwise stock 4.6L 3v engine.

This is what happens with boost + Nitrous and no tune. With a good tune and 8psi you should be fine. However your engine wasn't designed for boost so someday it may pop. just start saving for a new short block sometime soon just in case.

The stock powdered metal rods just like the ones in the 96-01 Cobras and 96-06 GTs are the problem. Those rods could fail at 400HP at high RPMs

The reason those rods flew apart inthe pics i posted was because of detonation.

It's all about the tune man
