I see alot of F body guys using larger crank pulleys to make more boost as opposed to smaller blower pulleys and dealing with more slip. Have any of your guys looked at this or is it unavailable to us truck guys. Is this a difficult job?? Im unsure as to what this would entail or how it would affect the rest of the engine. Ive been searching to find out more about it, but cant seem to find much.

 

Seems like that would be a good idea but im not sure myself how this would work for us truck guys.

 

Does the vortech use the factory belt line up? If so you have to remember that a larger crank pulley will speed up all the other accessories with it......not good for cooling or Power Steering.

 

Yeah that would be the only downside to that.

 

I think it does. Im a little unsure of what exactly you mean. I thought it was a bad idea to slow them down with the underdrive pulleys . Could you explain a little more?? Thanks

 

If the type blower you are using has a separate belt, you could have a larger pulley custom made like I did. I had to send in the original Whipple pulley so they could make a blueprint off it, then they made the new one to my specs. I had ASP do this, and it cost about $250. Other pulley companies might be able to do it too.

 

IF the Vortech uses the same belt line as the factory accessories then this will be an issue. When you speed up the Alt, P/S, and water pump you are basically putting more "miles" on them. Not to mention you will be over boosting your power steering and the coolant will be going through the radiator faster, not allowing for it to completely cool.

 

It uses the same belt. I didnt think of the loss of drivability that this would require. Anyone else have any thoughts/ experience??

 

With the procharger it wouldn't be an issue my camaro used a seperate belt to drive the blower, as long as the trucks are the same,,,no problems there, but i guess the vortech uses the same belt as everything else which brings about the problems listed above.
