some of you might have read that I'm getting ready to install my vortech kit. I'm planning on moving into the 3.12 pulley ultimately but am wondering what is involved in doing that?

Is it a lot of labor to install the vortech with stock pulley, then later change to the 3.12 pulley? Am I better off going to the 3.12 pulley from the start and not bother with changing it? Maybe it's easier to change out before the kit goes onto the car? Or is going to the 3.12 pulley really not all that big of a deal and is simple to switch to later? Does the blower have to be removed to install the 3.12?

I was thinking of starting with the stock one and reaching 380ish whp and break in the SC before going with the smaller pulley and a more aggressive tune

 

No need to break in the blower. When I installed the Vortech I went straight to the 3.12 pulley. My break in consisted of me flogging the chit out of the car to see what it had as soon as I drove away from my shop.

A few weeks later I was going to install the 2.87 and a crawford plenum, but I swapped the vortech for a Greddy TT.

 

hmm ok cool I guess I'll just do it all in one go then

 

Sentry,

I think the pulley swap is a pretty easy process in itself. The main thing is that you'd want to have the car re-tuned once you do the swap. I would go with the stock pulley to start, and if you decide you need more power, add the pulley later. Gives you room to grow, and time to break in.

 

Yes, it is easier to put the pulley on prior to assembling the headunit on the bracket.

 

that's cool, good to know it's easy.

i'm thinking i'm going to want that 3.12 pulley anyway because i'm shooting for 400-440whp. Maybe I can get it without the pulley, but I think I'd rather get my target power with the pulley and less timing than the stock pulley and more timing.

Plus it'll save me having to retune it again a few weeks later.

 

I would just go right to the 3.12 pulley .Save some money on retuning .
Although its an easy install . You can do it with out taking off the blower , but its not the right way to do it . The 4th bolt on the blower is a ***** to get off from up top , and its much easier to get to with the front wheel well section off . Same way to pull the oil squirter out to clean it
