Who knows GT500 and Math?

[Torchy]

So doing a Whipple tensioner, SPE fixed Idler and 2.6" pulley. All else stock.

SPE's table says 69.5" for that combo with stock tensioner. It appears the Whipple Tensioner wants you to reduce the belt size by 1.71" for a stock application.

If my math is correct I should be looking for a 67.79"-68" belt.

Anyone get anything else? Anyone does this combo?

I'm running the stock belt with the SPE adjustable aux idler and stock tensioner on a 2.6 ATM...

I have the whipple tensioner, but as of right now everything seems to be running solid so I'm going to hold off installing. With that said, I have NOT been ripping on it and my tune isn't complete since PBD is kind of a cluster **** right now for Remote tuning... Just gonna run it down there in June and have them throw it on the Dyno.
