ATI COPO Superchager Video Update

Looks like the belt has less distortion on lower pulley with the new set-up. Three speed helped out a bunch with more mechanical leverage.

Still to many idler pulleys on these supercharged cars.(SCJ+COPO)

Maybe they need to try this pulley setup.

The SCJ uses 6 idler pulleys and 2 different designs. The 2013 used 1 single belt to run everything. The redesigned one used 2 belts and was a better design. Still to many idler pulleys and too long of belt for both for my liking.

Definitely a tensioner with a beefier casting and seems to control the pulley windup better. I think everyone with a 2 step should watch the videos as they ( not all ) might try modifying their routine in staging ( time wise ) with the 2 step. It sure does slap that pulley around and that pulley is just a window to what is going on inside the motor. Just my observance .

I try to imagine what the crank and cam bearings are going through when on a Two Step.....

According to David Reher, it is the valvetrain that gets trashed on the two step.

I'm always trying to pull information from guys who have "been there, done that, got the T-shirt"
