I had ATI build me a cog setup for my F1R. Looks like they did a good job cant wait to try it out. The crank is 74 tooth and the blower is a Super Pulley Sprag 45 tooth.

 

What are the other pullies for?

 

They are ALT pulley, tensioner pulley, power steering pulley and blower spag pulley. This setup is a direct replacement for all of the stock pullies just as the 8 rib would be. The belt is 30mm wide. This kit is like the c5-c6 corvette cog setup but for a truck. They have had god luck spinning F1Rs anf F2s with it.

 

How much did it cost ya? Well hurry up and install it and let me know how it works out for ya. Outa be pretty awsome dude.

 

Its the same price as the 8 rib 1200.00 and the Super Pulley sprag for the blower is 550.00.

 

Should be a very clean set up once done. The cog I think will also be a little louder then an 8 rib set up.

 

I can't wait for you to get that on your truck. I want to see how much boost you are going to make. Awesome.

 

I second that

That would be a tasty little add on for this:

 

what unit is that Brian?
