OPG Needed on 2020 Models

[m3incorp]

In this case, I would say go ahead and change them out when doing the supercharger install.

Whipple blower to be installed.

I have done them on a 15 and now a 19 when I did my whipple. No need to worry about the oil pan tbh. I think it took longer to get the bolt out of the pickup tube on the 15 than it did to pull put all the bolts on the 19. And I dropped the bolt in pan, but a magnet at end of flexible rod all that was needed to pull it out. The drop on the pan from removing the bolts on the 18+ is all you need to pull the pump out.

I know the 17s and below models had problems but I haven’t heard of any recently that broke.

15-17s do not have a OPG problem.

 

[engineermike]

Does anyone know of any 18+ that have broke the OPG recently?

I’d like to know this as well. And more specifically, how many gen3’s have broken opgs when using the stock harmonic damper. I know an f-150 did but they have a smaller opg and didn’t get the fluid damper the car got.

Gen3 has been out since late 2017. How often do we hear about opg failures? Seems like pistons are the weak point on these...

I haven't seen or heard of hardly any piston failures on the gen 3, no more than gen 2 cars had.

One question that nobody seems to be able to answer is how the balancer / crank pulley changed again for 2020. It is indeed different than 18-19. If you install a Roush SC on a 2020, you must also change the balancer. My personal opinion seems to be they went back to the 15-17 elastomer balancer. ON a ProCharger stage II, 18-19 do not use cam locks. But on 15-17 and 20's they do.

This is all relevant to OPG's in my opinion

Then why won’t this issue die.

Don't believe everything you read on the net/forums. 99.9% of the time it's the peeps bouncing the engine off the limiter like a tard, or improperly installing a balancer. Roush offered supercharged s550 with FULL FACTORY WARRANTY w/ factory OPG. THink they or Ford would do that if they thought it was a problem ? 18+ OPG never changed as well.

Then why won’t this issue die. It’s seems to be turning into urban legend at this point.

Because vendors like to sell parts. I bet gen3’s break pistons 10:1 over opgs but it’s harder to convince people to change their pistons “for peace of mind”.

 

[Ruby_Ruby19]

I think the 18+ upped compression is harder on pistons. The consensus leans towards pistons being the weakest spot in the motor. As with all these issues though it’s hard to compare any failure to the next.

Yes they did have a bump compression, but the VVT makes it not really that high all the time.

Pistons are not the weak spot on the Gen 3 motors. Just wanted to correct that

So the lesson learned on OEM OPG survival is bumping the hard cutout REV limiter to 8000 or so RPMs?
I’m only asking, I don’t know the answer.

Hitting the rev limiter under full load sends harmonics through the crank which travel to the end of the crankshaft.

I remember the "cylinder 8" problems that made it all around the internet about 6-8 years ago as the weak spot on the Coyote. I almost got caught up in that hype and did the cooling tube deal at the back of the heads. Glad I didn't

Back then I had a Roush TVS2300 on my 2011 Brembo (6 speed, 373 axle). The car made 600 rwhp and 520 rwtq. I put well over 100 passes at the dragstrip on that car. It ran, idled and drove flawless. Had the blower on for 20+K miles before selling it.

My only engine failure was with upgraded OPG on a blown (550 rwhp) 2015 auto GT. The OPGs did not fail, the tuner did and broke ring lands on 2 pistons. They rebuilt the engine with forged parts and the pistons failed AGAIN! No OPG issue.

2019 Bullitt no opgs with Whipple and drag raced it before selling. Ran excellent.
2009 Bullitt (4.6) Vortech 488 RWHP drag raced, no OPG, Ran excellent for over 20K miles
Current 2018 A10 Procharged with guessing about 600+ RWHP, no OPGs.

I really think it is a blown up worry and once it gets into your head it's hard not to go out and mod. I look at all the guys doing one piece driveshafts, which I put on 2 of my cars. Loud. More clunking if shifting manually for sure. Many of the failures I have seen were with cars in the 600 RWHP area and aftermarket one piece DSs.

Every time I see a used car for sale with OPGs installed I always ask myself. Did they do it correctly? But, I am jaundiced as the only car I had OPGs installed along with a blower was my 2015 and the only Mustang engine failure.

Guys put these stock gears on a two step and don’t have problems.

Two Step stutter launch control doesn't cause the same type of harmonics as bouncing off the rev limiter @ full load peak RPMs

 

[WildHorse]

It’s the harmonics this engine produces that worried Ford enough to put an expensive balancer to get the 7500 redline

No, it was cheaper for FORD to go with a aftermarket vender. Just like they did with the Gen 2 coyotes. Coyotes balancing/harmonics are on par with some of the best engines in the world.

THANK YOU! THANK YOU! The gen 3 got some much bullshit from mainly gen 2 nut-swingers.

Every gen 3 car around here that I talk to is on stock OPG, boosted to NA. Unless the NA guy is cammed then they do them.

 

[GregO]

So Roush uses 5W-50
Is there some type of magic going on with 50wt cushioning the OEM OPG ?
Again, I haven’t a clue. Just asking.
