You can short route the belt on an SN, but it doesn't work as well as having a delete pulley. The angle of the belt on the tensioner causes it to jump around a lot. I ran it the short route for a long time before I gave in and put a delete pulley on.

Yeah I did that up until now and it only squealed at startup but just looking at the belt at idle, I thought it looked like it was flexing slightly and that could be what's causing my miss issue this whole time. I ordered the UPR pulley yesterday and hopefully that'll not only solve that squeal but also the miss feel that was going on. I'm thinking the belt was slipping and causing that feeling. I hope that's all it was anyway.......

Wouldn't have guessed that. Good to know.

Apparently my ex-husband made that mistake.

I think I have the UPR pulley too. My friend bought one from the beginning, and I think he got a good 20 years out of it. Probably 80,000 miles or so if I had to guess. It did eventually go bad, but it didn't fail in a way that was catastrophic. It definitely made obvious noises for a period of time where it was easy to replace it.

Nice man I'm really hoping this all is my issue and I mean everything that I've been experiencing so far after installing the vortech
