Don't be Just Another Failure!

[Doctor Fishtail]

I don't think anyone is lying, but really that is besides the point. What does dropping the gears prove? I don't think the engineers considered surviving the drop of gears on a hard floor as a design requirement. I don't think there was any question the aftermarket gears were stronger. The only question, which hasn't changed, is what is the failure rate on modified cars. Anything else is just white noise in the debate.

After the failures we have read about and been posting about I do not think anybody cares what the failure rate is. I don't. I bought mine 3 weeks ago and had them installed last week as well as an ATI Super Damper. The only weak link left IMO is the Timing Chains. And Quackfoo in his/her post was calling BS. What do you think that means? I took it as calling MyLilPony a liar.

If your doing any kind of build for power pump gears are excellent insurance! If your leaving it stock I see no need to change them!

Here ya go....this broke is 3 drops...


"But wait it wasn't on wood" "you threw it at the ground before" "that's not real" "wasn't the same distance" blah blah blah figured I get all the flame posts outa the way..

That, could not be more of an perfect example of cheap quality gears. Why Ford would install such an obviously inferior product is mind boggling. Crank Jerk is the reason they break in the engine. This can happen simply by hitting bumps in the road while under WOT.

im by no means an expert, but i would say if you are already installing a supercharger or upgrading internals then it would be an obvious choice to add OPG's during the same install, but I would not spend the $ for 8hrs labor just for this job on its own...

More videos of destruction testing of the OPG!

I thought about this long and hard. Read many posts and articles. Came to the conclusion that spending more than $40,000 on a car and not doing this is like not buying insurance thinking I will not get into an accident.

Damn! But it is powder metal guess that's what's supposed to happen.
In all seriousness, the wooden floor thing. I've seen hardwood floors in houses of course and wooden sidewalks and bar floors in ghost town or mining town type tourest towns. Didn't know that they would still be in place in actual businesses. Thanks for the video.

I'm with the other guy, still not thinking it makes a whole lot of difference in that there haven't been a crap load of failures with all the superchargers out there. I saw that where the ford engineer said the OEM part is good to 8000 rpm, which I doubt my engine will ever see. Sure is tempting though for that peace of mind thing. Thanks again for taking the time to video that.

We have a load bearing part on one of the products my company makes that was recently switched over to powder metal for cost. It could seriously hurt the user if it fails during normal use. Lots of testing went on with the design and it was deemed totally acceptable since it was designed with plenty of safety factor built in.

Not quite. You aren't putting $40,000 at risk.. You are spending ~$2000 to insure ~$7000 (failure recovery). Keeping the insurance theme going, to pay so much to insure so little would mean the failure rate would need to be almost certain. Think about spending $1000/yr to insure a $500,000 house or $1200 year to insure a $50,000 car. Statistically, it is probably as likely a modified Mustang will be in a car crash as have their OPG break.

Let's be real though, this isn't a dollars and cents issue. This is emotional. It makes people feel good to avoid this pending danger. It is a warm security blanket in a heated home.

I'm not sure he actually said that. He said that uncontrolled torsional vibrations is what will cause opg to break. The engineer said the oem damper was good for factory rpm and that at 8,000prm, one is exceeding factory limits.

Probably stands to reason though, if one gets an aftermarket damper, the stock opg will be good for more power and rpm as the uncontrolled torsional vibrations should be minimized/eliminated.

Until this weak gear fails then we will hear you change your tune. Or we will not hear from you at all. I drove car very little until I did this mod. And did not cost me $2000 it was $1500 parts/Labor. :thumbs: Mine is done. I can sleep at night. No more emotional sleepless nights.

My "friends" car is stock but it is sometimes at WOT (in 1st, 2nd gear) when there is a defect in the road that bumps the rear wheels which seems like it could transmit shock back toward the engine.

 

[mustang1]

I thought the OEM OPG would require more than just a drop, even if on concrete. Maybe a throw or a hammer strike to simulate "shock loading".

Anyone have an MMR gear they can test on?

My first concern was whether the OEM OPG was really that fragile. My second concern is what happens if the Chevy / Dodge people see this video. :lol:

 

[MyLilPony]

Kinda right on the math. I spent 750 for install, $550 for gears so roughly 10% of my total build. For a centry like me I do not have to worry about the motor blowing and taking my supercharger with it. For PD guys that could happen. So 10k spent then a total 15k to rebuild so essentially for what could be a total of ~$25k all in, if if all fails you are less than 5% of the total build/rebuild total. There are A LOT of what it's in there though...

Either way you are right. This isn't a rational cost justification insurance debate. It boils down to "I do not want to potentially rebuild my motor right now" issue. Which could all be out the window if I pop a ring anyway... I do plan on going above 650 at the wheels so for me, well, why not put them in?!?

I am not so shallow that I can't admit I'm wrong. All we know is there isn't enough data to prove or disprove anything. The history of hyped automotive fixes on forums that didn't pass the test of time is extensive and should instill skepticism in all of us.
