I'm looking to get my XR rebuilt/replaced. I love the SCX/SC combo but don't think I want to spend the dough on a 1997 boat. My engine is a custom 496 with a Blower Shop 250 w/7lbs of boost. Base engine dynoed 600 hp w/o blower so I'm guessing engine is making low 700's for power? I used to run a Procharged/R-tech intercooled package that made 825 hp for about 90 hours through this drive. I never had an issue with my 130 hour XR but I'm told I must have a good one! Just figured I better do something before it bites me. I saw some videos on You Tube for Max Machine and I've heard good things about the Teague Platinums. Thanks in advance!
