All Around Great Guy
Will you still grenade the engine if you do not go over 5700 rpm's with a motoblue underdrive pulley installed?
viper1 said:because these pulleys are allegedly balanced incorrectly for the high revving hemi engine? so its been said and proven in more than one case. do your self a favor talk to Bluebeast or STU over at DTW and I am positive they can steer you in the right direction.
Yeah Matt...I still feel a little guilty about that.HEMI450HP said:Its true guys. For a while everyone was running a Motoblue/ASP underdrive pulley and they were breaking their toner rings and having to have their motors relpaced...so STU at Heat Performance made an upgraded toner ring. I WOULD NOT run an underdrive pulley without one of STU's stronger toner rings.
You notice how nobody has broken a toner ring lately?? Thats because they stopped buying the pulleys after the scare a while back.
It is at the back of your motor and it is what your crank positioning sensor gets its readinf from. The toner rings were breaking causing them to shatter that crank sensor...then the pieces of the toner ring will run through your motor damaging almost anything it touches. I know of 14 guys that have replaced their motors because of this problem and all but 1 of them had the pulley. I had one on mine for about a week and took it off immediately.varedneck said:thanks i should have known when it did not line up very good and they sent a narrower belt, so what is a toner ring and do
I did...Thats why I took mine off. Mine would leak about 1 drop of oil every hour with the pulley installed, so I took it off. With the stock pulley back on, I dont get any more vibration, and the oil leak went away.varedneck said:did anybody notice any oil leaking around the seal of the pulley not much just visible
