Always wanted to put a temp probe in that damn box and get the actual reading, doesn't seem to holdup long enough to bother. The Idaho trip is the longest it has been under a sustained load and did run considerably cooler using Red Line 50w racing oil @ 3 quarts (I will NOT run the recomended thick gear oil ever again) The noise I heard at the end of the trip has not been identified yet, but DS and I are leaning toward axle/suspension bind of some sort (hoping so anyway..) It was something very different that the last noises of a failing Jeffco. Will know more in the next few weeks..
What did you end up finding on the noise?? My oil pump died during the first 3 hours of operation..Granted it was used when I picked it up.. It didn't agree with the gear oil..
When I drained the oil to do the inspection, a few pieces of ring gear dropped into to pan. Viewing through the fill plug, I could see about 6 teeth with the edges missing. Plugs went back in and car pushed out of the way. Jeffco box is a complete failure that can't take a boosted Busa, period. It will be removed from the car and I will not sink another penny into it.Soooooo, sprocket drive will be going in it's place!
I have a near new Mocal lpump if you're interested
That freakin sucks... you've ruled out the rpm box or just over the expense ..
He's more interested in going forward without haveing to worry. He likes to mash the fun pedal!
well that's like trying to find unicorns that Poop Rainbow colored ice cream... worry free on a ( correct me if i'm wrong ) 350 hp busa package.. nope.. lol
