Do we have a lower pulley also?

[blackonblack06]

The reason I ask is that on the Cobra they have a lower and upper pulley. Changing the lower pulley adds more torque for some reason. I haven't really looked at the engine cause its been raining the past few million days and don't feel like raising the hood. THanks for the input.

I assume that you're talking about the crank pulley? Or some of the other accessory pullies. Although, once you make those larger, reducing the parasitic loss of the accessories, then you HAVE to use a smaller pulley on the blower just to make up for the lost speed. The reason they use those pullies, is to slow down the accessories so the suck up less power. I'm sure that we do have a crank pulley, it would be pretty odd not to, but you would have to get a smaller pulley than we can currently fit on there, just to get the boost back up above normal.
