It still doesn't address the heat issue the turbo guys are seeing...300 degree belts. lol
If you are seeing 300 degrees it really doesn't mater which belt drive or chain case you are running, Install a heat shield. If your turbo kit did not come with a heat shield then shame on them for sabotaging your machine and it's reliability. That's what one would expect from the low bidder in the turbo wars.
Don't expect the manufactures to be Physic and foresee what you are going to do; and then thru your ignorance try and destroy their hard work and reputations.
