What can the 2015 Ford SHO stock internals handle?

[SHOHARD]

I have researched on line and can only seem to find the Gen 1 & 2 internal power. I would like to know what the stock internals can handle? What is the MAX power AWTQ and AWHP? I believe the stock turbos can handle max 17/18 PSI.

Thanks

Generally speaking, if you want a mix of combined safe power, and long term reliability, then a range of 550chp, or 425whp is the norm.

Have there been anomalies above or below that, where failures have occurred? Yep.

But that's a general target range for stock internals.

Keep in mind, FMC rates the 3.5L @ 365chp, and average stock whp ranges in the 277-281whp.

So, to expect 550chp from the stock internals is not too shabby really.

The internals on the F150 are forged, and are stronger, whereas the internals on the SHO are some poly metal something or other.

Basically what bpd said. That 420ish whp is the standard for keeping it reliable every day......as far as I know. No one has really just tried to find the absolute limit of the block until it sends a rod out the side.

Thanks bpd that makes me feel alot better. I really want to be around 415 WHP, then I will decided to upgrade my internals. I really wished they would of put forged internals, I hate when designers go cheap to save money.

Everything that I've seen is the F150 uses cast pistons.
