Is the 5.0 designed for boost?

It was also on a 2 step only reving to 3100 RPMs. It was not bouncing off of the rev limiter

sustained start stop..... that's what it doesn't like.
That's an opinion. While 2step use would not prolong the life of oem OPG's, stating definitely what the issue is without real data is simply an opinion.

what happens is when over reving the coyote you suck the oil pan dry. if you check the clearance on the bearings the coyote normally should use a 40 weight so 0w40 or 5w40. there's always exceptions
Show me where a 40WT is recommended by any engine machinist for a main bearing clearance of .0009-.0016"

I mean that is true for every car and nearly every mechanical piece on a car.

I personally don't see how the OPGs were being stressed any more than normal under the Trans brake and 2 step. Anymore than it would be from foot braking it to 3k.

With a 2 step you get power pulses when the ign cuts on and off. This could cause the gears to hit and the hard stock gears break. The soft aftermarket gears gall.

When on the foot brake the power is steady, no pulsing.

Makes sense!

Doesn't the transbrake just hold the rpm vs the 2step which is an ignition cut? It's literally like bouncing the rev limiter. If it is, then that's like cruising in 4th with MT82, that's not a problem that's a constant rpm.

If this is an opinion you can't accept without fact, just ask around how many people have broken opgs with 2steps. I personally think that's harder on them than revving it to 8k.

I read where a ford engineer literally says using a 2 step is something those OEM coyote opgs aren't designed to do.

The crank is rapidly accelerating and decelerating to maintain a specific RPM based on ignition cut. There is alot more inertia and force involved at 3000rpm vs a normal startup.

The transbrake doesn't do anything to the RPMs. If you have a transbrake and no 2 step it will simply rev to whatever you throttle it to or blow up.

The 2 step is what attempts to hold the RPM constant. I can see how that would strain the OPGs as it is bouncing off of the edge of that. I just didn't think it would stress them that bad since it was only around 3k RPMs.

The transbrake simply introduces reverse when engaged. You can use the transbrake at any rpm you like, 1000rpm or 15000 rpm. The 2 step uses ignition cut to maintain your specified rpm while on the transbrake.

So, it's like launch control. Just steady RPM. That doesn't 'compare to a 2 step

Yes it's literally launch control. What do you mean it does not compare to a 2 step?

The 2 step holds the RPMs at the designated setting and the transbrake allows you to put the car in gear and then load up onto the 2 step?

Without the transbrake the 2 step is not that helpful. Your brakes cannot hold the car with 6 pounds of boost and 4k RPMs sitting on it.
