Gotcha!! If you go with any Centri you want to swap the intake out. The Fast is not very strong when it comes to boost. A stock LS7 intake will handle 21-22psi where the Fast is rated for 15psi but is prone to crack. I would do a G3X and start with a 3.8/10%.

Balancer is an Innovators West, not sure if under/over driven


How is customer service on the ESS head units? Heard some stories...

You can measure it. OD will be 8". The UD pulley is 6.75"

I haven't had any issues with them. They have a place in Arizona. Do you have a supercharger setup now?

Reason I ask is because ESS does not sell a kit for the C6. They sell brackets and a head unit. No hoses, bov or intercooler. You need a A&A kit and have to use their idlers pulleys and tensioner.

ok, so I would need to buy a complete A&A kit minus head unit? Could either buy without one (if possible) or sell the 1500 unit and add $ for G3X...


Maybe just try and find a used setup (brackets,intercooler ect) then

If it were me from scratch I would do a Procharger Race IC ,procharger piping with one of their Race Bov's and radiator spacers . Then order the tensioners and idlers from A&A. Brackets and Headunit from ESS
