Max power output safely??

[myersroofer614]

I have JLT, sct BDX, no cats, Roush exhaust, sb air cleaner, looking at procharger variable boost... How many psi safely as max? Plan on 6, 8, max..
Eventually heads n cam. But drivetrain Max power?

There is no “safe” PSI on a factory N/A engine. It’s a matter of how many precautions have been taken in terms of preventative upgrades, tuning, fuel quality, and the manner in which it’s driven. Pre-ignition, especially at high load/low engine speed, can crack a ring land or put a rod through the block the first time it happens.

As far as Heads and cam, they essentially do nothing on 6.2. In one of the more popular threads on here people actually lost power and driveability after “upgrading” the heads and cam. It’s limited by the factory design.

despite the haters, theres been many folks with great hp numbers, that have put many many reliable miles on the stock 6.2L engine. not too sure about the procharger, but whipple has always been the gold standard for the 6.2L.. anything can happen to any engine that isnt tuned properly, and he's right theres no magic boost number thats going to blow it up. best bet is to get it to a reputable tuner and get all the EGT and AFR numbers right on a dyno..

Thank you, Livernois motorsports is near me in Detroit

Have a 5 Star tune rn

Not sure who’s hating, it’s reality. The stock 6.2 is plenty reliable, but that is irrelevant once F/I is added. And that applies to any engine designed to be N/A from the factory. Engine design is not interchangeable between N/A and F/I applications.

Livernois a reputable tuner. They will most likely recommend oil pump replacement before the addition of any supercharger, as the harmonics and shock loading from the supercharger drive can crack the oil pump gerotor gear, resulting in engine failure. The pump is $500 plus installation, so probably ~$2k total for that.

As far as the rest of the drivetrain, the 6R80 seems to handle a decent amount of power over stock without common failure, although they tend to exhibit planetary thrust bearing wear when subjected to higher torque numbers.

The Sterling 9.75 is a stout rear axle, but the issue is keeping it under control. Even in stock form, leaf springs will exhibit significant wheel hop under load. Combined with pinion angle deflection, you can take an axle that can manage the power but will fail due to shock loading, movement, and deflection. Traction bars are a must have at minimum, but will significantly limit axle articulation off -road.

Deavers spring are in the future, and oil pump is covered on my warranty. What brand pump i need?
Ty for the info.

What warranty do you have that covers oil pump failure caused by aftermarket modifications? Must be a best kept secret lol!

Livernois pump is a Ford OE pump that is upgraded in-house with billet gears:

As far as suspension, Deavers will not prevent wheel hop or pinion deflection. Traction bars are necessary at minimum; the torque output will overwhelm any leaf spring setup.

They don't need to know about the add ons..
