Good Evening Van,

I'm curious about belt lengths, as well as idler pulley size recommendations for the following setup:

• 2009 GT500 with a 2.8 Kenne Bell
• 10% Overdrive
• 3" pulley (pump gas tune)
• 2.75" pulley (race gas tune)
• 2.5" pulley (race gas tune)


Also would these belt sizes be available in the new blue belts?

There are only 13 - 84" Blue Belts remaining that are new in existence. There are 12 - 85.3" Blue Belts remaining in existence that are new as well. 86.4" new blue belts are gone. Gates will not be making blue racing belts moving forward they will make racing belts in black moving forward.

As to the size you are looking for.

3.00" with 10% OD Lower is an 87.9" Belt and it drops to 87.0" with the 2.75" and 2.5" upper pulleys.

Thank you for the response Van, is it possible to run the same belt by using the 90mm idler for all three combos?

Most likely not as you're lowering the pulley size by 1/2" and asking the belt tensioner to take up the slack. I've had a couple guys try it and end up ordering a shorter belt for racing with the smaller pulley set up.
