Blower belt slippage cross post re new Monster Mustang.

[PhoenixGTS]

I recall AB and maybe others mentioning that sometimes you blower guys have serpentine belt slippage issues. Looks from this picture that the new Monster Mustang GT500 uses an eight groove/nine tine belt instead of out six groove/seven tine (I am assuming the GT is the same). It would obviously be a heck of a project to make all the pulleys for a convertion, but if this is a big issue for you boosted folks it looks like Ford SVT votes for a wider belt.

Belt smelts! Who needs them anymore! Just playing!

I had a 10 groove on my Heffner setup!

What did you do with the alternator and other pulleys not on the blower? Someone makes a 10-groove pulley kit?

They aren't run on the same belt. The centrifugals use an additional pulley on the crankshaft in front of the stock crank pulley, and the only thing it's running is the blower.

Thanks. I did not know that. Let's me know I could do a centrifugal without goofing up my underdrive crank pulley/overdrive water pump pulley combination.

It's amazing that Ford needs to use a blower to make 450 hp on that new Mustang. On the other hand, if DCX used a blower on the new coupe . . .
