Supercharger cog belt being constantly chewed

Pro4Jackster · 01-26-2015, 01:14 AM

It looks like he shaved down the lip on the pulley to help it clear the motor. I had to do the same thing. I don't know the clearance differences between the HR and VHR, but I could not cut a notch big enough to clear. So I had to have a custom idler pulley made. It was 2.5" if I remember correctly. JTran did the whole thing, and may still have my entire cog setup. That will give someone a smaller idler to be able to run a 34T/30T cog combo without notching into the motor.

I am looking at the picture you sent me and my supercharger cog pully is much narrower than the one in your picture, I went and measured it and it was 35mm in width (not 50mm) and I doubt that the shop that did the install shaved anything of the engine to get it all to line up. I think I will have to go with the 50mm wider supercharger pulley (2A032-030) and build the brace to help with the flexing and hopefully that does it.

Also, look how shiny the lip on your idler pulley is on post #1. I can't tell if it has been shaved down, or if it's making contact somewhere. But, keep a close eye right there, the cog belt can try to walk over it under load. A fix would be a smaller pulley with the lip left intact.

Car is at the tuners shop now and I emailed him the link to the thread LOL. Thx for all the help guys, hopefully he comes back with good news.

i had this exact same issue. Had this bracket installed that Nut_n_much referred to; works like a charm:

Nut, Great info man! All things I looked at to before I popped. Now that you mention it they did the same thing to my timing covers( Cut a grove) but there never could get the belt from chewing :/ So I took the cogs off and popped anyways :? The cooling tank can be found on any Mustang performance site, they make them for the SVT Cobra's

This time around I'm using GTM Kit. Should be fun.. I liked the larger heat exchanger you used, we got one for Kelly's car but ran out of time to put it on. He moved to Kentucky. The sheep got nervous day 1

ANMVQ · 01-30-2015, 08:24 PM

Definatly wanna see that kit on the dyno when your done . They made a very good kit to bad they went :O

clkio · 01-31-2015, 11:07 AM

So much great info guys, thx you so much NUT. I couldn't find much about this issue before this thread which surprised me because I am sure lots of guys did this and ran into the belt problem but ended up giving up maybe.

JWillis72 · 01-31-2015, 12:42 PM

Great idea! If my new cooling set up doesn't stop my heat problems I will be doing this, thanks for the info!

Just a small update on this, the tuner shimed the pulley and added spacers on the blower side and that seem to have did the trick, been driving the car around and everything seems fine so far
