New belt for smaller pulley
I received the 3.5” pulley for my 2018 Whipple today. I am thinking that I should be ok with the stock length Whipple belt with the 1/2” smaller pulley but would like confirmation. It’s the HD belt that Unbroken recommended.
Whipple says I need a custom tune to run the 3.5” pulley so I have to wait about a month until ID Motorsports starts custom tuning the 2018 before I can install it.
Between the Whipple, long tube headers, and high flow cats this thing will blow your doors off. Can’t wait to get the extra boost from the smaller pulley and ID Motorsports custom tune.

He said that you can go to a 3.625 pulley if you are running 93 + Boostane, or 109 race gas, or 93 octane and long tubes headers with no cats.
would be very cool if Id motor sports can get the 3.500 to work.
