Is installing the Procharger also a good time to install a pulley?

Default Is installing the Procharger also a good time to install a pulley?

just as the title says, i looked at the instructions for installing the ATI and i jsut thought it would be an easy and convenient time to install an underdrive pulley, any thoughts? thanks!

LOL! They use the crank pulley to drive the S/C and it will affect the output of the unit so I don't think it is going to happen.

Yes....the blower belt does not utilize the harmonic balancer at all.
The only install I am familiar with is the GTO, the procharger pulley has 3 pins that contact the OEM pulley webing. I went with an aftermarket fluidampr which allowed for a different procharger pulley that is bolted to the fluidampr.

In either case you must drill and pin the pulley to the crankshaft. the only question I would have is will the procharger pulley bolt up to what ever underdrive pulley you want to use????

that is a good point which brings me to this question, are there people running, say, an ASP pulley with a procharger? id be very interested to hear this

There was someone over on the LS1GTO.com that was having an issue with this, I believe he wound up having to get the fluidampr setup like mine.

Best bet would be to call Procharger and see what they say. Also I think Bob at EPP would know as well.

The ATI ProCharger D-1SC 8 rib assembly for the F Body's require a new harmonic balancer, made by ATI Performance Products, which is a different ATI company. This balancer goes for $475.00, and has the accessory pullies built into the back of it. You can indeed purchase it with the accessory pullies being driven at a 10% underdrive, which happens to be the one that I always order. I figure why not, it goes for the same price.
The ASP will not work for your application. Bob
