I've heard that: www.madmanandcoracing.com will do conversions to cog setup but he is in Texas I believe? But someone closer to you to try would be Mike Moran at Moran Motorsports in Detroit. Another place that could also do it will be Fast Times Motorworks in IL.

Hope this helps.

Unless you absolutely have to use a cog belt don't do it. They are very noisy and extremely unreliable. Not to mention $85 each, if you can get a deal on them. I've seen someone go through 4 belts in 2 days, then again I've seen a car trash two brand new F-3 blowers in 1 burnout and 1 half pass before

 

I bought a kit from Auto Specialties as above. Nice stuff, but ended up fracturing the gears on the blower (at least that's what I was told by an independant dealer who wasn't being asked to warranty it).

If you're swapping due to belt slippage, get a brace for the blower and one of Scott's tensioners; it will work. I ran 16 psi of boost on a D1SC with only an 8 rib belt. Slippage issues with the factory ATI tensioner (plus the bearings don't last very long) so I swapped the SDCE tensioner to the car along with a brace he made; all issues gone.

You can reach Scott at (401) 732-4047

I just always wonderded - what is it about the cog setups that make them so "unstreetable" - in the end what's the effective different between them and a normal timing belt - is it the length that does it, the "cut" of the "teeth", etc. - if a timing belt can last 80k miles what is it about cogs that prevents them from lasting 10-15k miles?

The LT1 cog systems I've seen all had problems. Even Madmans car goes through belts fairly often. Now if you only run 10-15psi you shouldn't have any problems but if you do then why would you need a cog belt?

 

I would also recommend going with an SD concepts spring loaded tensioner.

 

How much do they run roughly? I dont want to call because I dont have money and will get excited talking about it.

 

If I remember correctly it cost me 450.00.

 

The above is about right if you already have a system and need it modded for his tensioner. If you buy the system and tensioner from him it's considerably less as he'll delete the ATI tensioner from the kit and credit that back to you. His tensioner needs some mods done to the main bracket to work, not a direct bolt on. It is WELL worth it though to eliminate the belt slip issues.

Jody

 

What kind of mods did you have to do?? The reason I ask is because mine was a direct bolt on.

 

Maybe Scott has a direct bolt-on for yours; if you bolted it on without sending the bracket back then he must have. He told me that all of them need the main bracket sent back to him for machining for his tensioner to work.

Jody

 

Nevermind I just confused myself.

 

Did you send yours back to him for mounting or buy the kit from him with that tensioner installed? Or was it a bolt-on to the stock bracket? I don't want to give out bad info!

Jody

 

I had to send him my blower bracket which he modified to incorporate his spring loaded tensioner. (You info is good)
