Power Being Made Beyond Redline - 8,000+ RPM

That engine likes to rev high.

The Predator is a freak.


Pick your poison.

We've revved one higher. More info next week.

At point is failure likely....that is what I want to see. On somebody else's car of course.

What sort of warranty does Ford offer with these cars that they KNOW will be run SUPER HARD??

Probably none. You rev it that high continuously and if something happens they'll check the ECU and u r screwed.

It'll be 1 Predator engine for u on your dime not Fords.

Wonder if it'll make more/better power with turbos instead. That's gotta be a lot of parasitic loss with the s/c turning that fast

Damn.

Raising the redline isn't a news item.
Getting more hp by raising the redline isn't a news item.
Those minor tune tweeks void the warranty, a game Ford can't play..

Anyone who knows the equation to calculate horsepower from torque isn’t shocked.
The question is when does it make peak power?
I’m going to guess 8200rpm range stock, and I’m sure it’s on one of the vids from the max effort cars from Lund or PBD.
I do like Evans channel, bringing great content.
I bought a fully built Lasala 6R80 threw Sam at Costal. He was great and good to put a face to the name.

Based on formula’s, it’s eating about 100-125hp on top.

I like the valvetrain stability of these 5.2’s. Unlike my modular 5.2, which has been tricky to keep happy above 7500rpm, these seem to handle it fine.

Power wise, it’s not a stretch to just look at what gt350’s make with turbos and then factor down for compression.

It would be very easy to make 800whp on a predictor mill with a custom twin 62mm system on 10-11psi. It’s already been done with ported fgt head/stage 3 cam 5.2l big bore modulars running 9.3/1 compression.

Center it on a gt350 intake manifold, and let it eat. It would need some tuning and boost by gear/rpm/load like fat house has been doing to be able to 60ft for anything worth noting though. Taking 200-300wtq away from a 4133lbs car at 2500rpm will be like cutting balls off a pit bull.

I wish I could recall which Coyote development article I read that mentioned Ford's incremental improvements to valvetrain stability. I think it was a patent for an improved rocker arm design for the 2015+ Coyotes.

Tasca Parts shows the same part number for 2014 or 2015 rockers (BR3Z-6564-A) 2018+ shows a different number - JR3Z-6564-A

With all the race experience on the DOHC applications over the years, including not just the Coyote and CJ/GT4 cars but the Ecoboost in GT and Raptor; Ford has shown how to make them work in extreme applications.
So yes, I do feel like these cars at 20psi and 8000rpm will live.
Time will tell right?
I believe the input shaft limit on the DCT is 9000rpm....
