There is no belt dust around the sc pulley but the 2.85 I bought is a high traction. No belt dust anywhere on the serpentine side. I went ahead and ordered the high traction jackshaft pulley. Wondering if I should go ahead and change the sc belt also?

Can you guys give the part numbers or link for the pulleys that you picked up from Vortech? Or let me know how you communicated your needs to Vortech. I want to change up my pulleys now for the high traction design given my lower-than-expected boost issue to see if that might help. The CRC dressing got me .3 more psi haha

I saw this one, Part# 2A038, on the Vortech website. It is the same part number for the "normal" 8-rib supercharger drive pulley and the "high-traction" pulleys...

The high traction category doesn't have a 3.4 option... Otherwise, I'd go back to the 8lb serp side and do the 3.4-3.0 jackshaft-SC on the SC side like Topz

I was thinking of keeping the 9lb serp side and ordering two 3.15 (is this what y'all are calling the 3.2?) high traction to replace the SC side.

And to answer the question, you might as well replace the belt, knowing that you've worn the belt a bit and having everything apart.
