Don't be Just Another Failure!

[Roh92cp]

Whipple usually knows what they are talking about and if they don't think it's needed I'd go with their recommendation. If you're a track junkie though it's probably worth the peace of mind.

I would agree, and if I was gonna track my car I would have OPG, TG as well. Race damper for now will hold off the daemons on my street ride.

The bottom line is that these parts DO fail - even if the percentage is small, is it worth the peace of mind to address the potential issue prior to making more power? For me, it is

I plan to beat the piss out of this car so mine is getting the OPG and crank sprocket. No sense in >600whp if you drive it like a Camry.

Thousands of Whipple SC S550s out there?????

Time to stop making suspension. Joining the SC club!

I think the percentage of failures is much lower, but yes who wants to risk it right, well I did and only becuase mine is a street car won't be raced. According to Whipple they have thousands of cars out there without OPG and timing gears without issue and they have extensive and harsh durability tested with many hours on there calibration. Whipple has assured me that it's safe to run there cal up 700 whp and of course that's not a guarantee and it's always better to be safe than sorry.

Yep, and they even offer a warranty. I'm skipping OPG's and timing gear and just sticking to a damper.

shoot, if youre on this forum it seems that way!:frusty:

Just dropped my ride off to have the OPG and TS installed. Cost justification was easy "replace motor or gears?"

Paxton and Procharger need to up their game and offer an engine warranty as well.

According to Whipple yes.

The "peace of mind" reason can be used to justify almost any upgrade..

An actual Ford engineer saying that there is an issue with failure when going higher in RPM or power should be good enough for anyone.

It's a shame the post was deleted from the forum.

Right but what he actually said was the torsional vibration and harmonics caused by forced induction and higher RPMS was out of the scope of the stock dampener. He further stated that a race damper was the key in dampening the harmonics that break the OPG and timing gears.

I found the post by the Ford Engineer for those who didn't see it.

The following excerpt is from personal email exchanges from April, 2016. It is posted with permission courtesy Mike Robins, Supervisor, Ford Performance:

This is coming from our engineering team and also the party that inspects every engine we look at that has experienced issues.

Uncontrolled torsional vibrations break the oil pumps.
It is not the oil pump gear material or the heavier oil that breaks the pump.

The large mass of the flywheel /pressure plate or flywheel / torque converter control the torsional vibrations at the rear of the crankshaft. The vibration damper controls them at the front of the engine.

The production vibration damper is designed to work within the production vehicles RPM limit and power level.
At 8000 rpm you are past that limit.

Changing engine internal components and or installing power adders can change damper requirements.
Just installing an aftermarket race damper is not always a fix.
Some aftermarket dampers are not tuned correctly and do not control the torsional vibrations.

Why do Ford Performance and other companies sell oil pumps with steel gears?
The steel gears will survive longer in the harsh conditions of uncontrolled torsional vibrations.
Some of the other components that are subjected to the damaging torsional vibrations are the timing gears and chains.

People that blame the oil pump gears or the timing chain gears and chains as being substandard do not understand the damaging effect of uncontrolled torsional vibrations.

Regarding your ATI damper question, the ATIs seem to be fine, we use them in the Cobra Jets. We've seen issues with other brands I won't name. You can certainly pass the info along! There's no objection on my part as long as the context is fitting, you may even want to paraphrase, etc.

Thanks again!

If it was such a huge issue WITH the right damper, I doubt Whipple would offer their warranty.

So just finished getting my ride back from the OPG and TS being installed. I was talking with the owners of the shop and he was telling how fragile the stock OPG really is. I was already sold on installing them and in fact all I paid him for was labor but he asked if I wanted to see how fragile they really were.

He took a stock OPG and then an MMR and held them them both by his side. Standing over a wood floor he dropped them both from around 3ft in the air. The stock OPG shattered (MMR was fine). I then offered to sacrifice mine to ensure it wasn't pre broken and it busted in half!

Now I know opg's are not meant to be dropped but damn! If a small drop will bust the gear 600+hp boosted coyotes are sitting on a ticking time bomb with the stock gears.

Thought I would share; just another confirmation I made the right decision.
