anyone using these ? i just seen one on a dyno make over 1000 whp on a supra ,,,are trhey any good ?? will they last???

 

I've been told they work great but need to be repacked/rebuilt just like wheel bearings every 20-30k or so. You also have to run coolant lines. This is from the guys who are very tight with comp. I'd love to try one but I don't have that kind of money. I'll settle with my precision and run an oil line for the time being.
