First run...shredded the supercharger belt, found lower pulley alignment off and did some machining to the tensioner bracket spacers, much better. Second run ..shredded belt #2, figured out that rpm was ballooning and colapsing tensioner causing belt to come off pulleys. Fabricated solid adjustable tensioner to keep belt from being able to move TRD spring type that comes with S/C kit. Next few passes ..FUN, got to turn on nitrous, methanol etc. Pulls like crazy under boost when tires aren't spinning. Latest run, barely pulled boosted load on freeway on-ramp, engine starts fast high pitched/loud clatter :Wow1: Gonna pull pass. side V/C next week and take a peek, but already made a call to LC engineering to start building a stronger bottom end.:sombrero:
