This is for the 4V people that have busted your oil pumps. To help put the "UDPs break oil pumps" thing to rest I'd like to know the circumstances/setup that lead to your oil pump failure.

Piggyback UDP move the dampner further away from the crank which lessens it's ability to dampen harmonics.

So far only 1 person? With all the horror stories floating around the interwebs you'd think there would be more.

I didn't vote because I never broke an oil pump.

Bumpity. Please post if you've busted the pump. I am trying to get the misinformation regarding this subject sorted finally.

Bueller? The lack of responses are making me think that there is more fiction to this than fact.

Ok well I will tell you what 2 of my friends had when they shattered their oil pump gears. Both had BBK pulleys and both did it at the track. I'm gonna guess they were around 6000rpms when they shattered. I personally like the BBK pulleys because I got to rebuild both of those motors $$$.

Were those on 2V's or 4V's? The more detail the better.
