Belt size with Unorthodox main pulley, Greddy WP and ALT pulleys, and air pump
I did lots of searching for this belt size but found nothing beyond "get some string, measure, and then go to Pep Boys". Even Banzia Racing's belt guide did not have this combination listed.
It took a few trips back and forth, but eventually I found that the 1385mm (54.5") belt did the trick. The Goodyear Gatorback part number is 5PK1385 (or 4050545). This is a 5-rib belt.
I also found that the 1000mm belt recommended by Banzai for the Unorthodox main and stock AC and PS pulleys would not fit and I needed a 1015mm belt (6PK1015, 4060400). This is a 6-rib belt. I had the idler pulley to the maximum open position too. Not sure what other peoples experiences are here.
FYI, the RX7 Store and cheapo eBay WP and ALT pulleys are the same size as the Greddys.
