Do you have a pulley from ATI that is specific for the procharger or are you trying to use the pulley that comes right from the kit?

Oh, and sorry I didn't see this. SVTPerformance has been doing some weird stuff lately.

Haha yea I get you, it wouldnt let me PM you for some reason. Nonetheless, I was concerned with the 12 rib not using all 6 bolts from ATI on the balancer. ATI stated to use all of them, but procharger was like yes with regards to using only three. I managed to mate everything up.
Other question is if you managed to wastegate your setup- i wanted to go this route but couldnt really find anything.
thanks again!

Glad to hear you got it all mated up. I used the ATI on with my 10 rib setup and the only thing I needed were the longer bolts that came with my balancer.

As far as waste gating the Procharger, I have not done it. I actually spent a lot of time chatting with the techs at procharger and also talking it over with my tuner, and it kind of sounds like doing this can damage your centri blowers (yes, I know others do it, but alas, it can wear them out pre-maturely).

With that being said, of course the reason for doing this is to make more boost down low and attempt to get more torque that the centri's don't make compared to twin screws. I can tell you this, with my D1SC, on the dyno with only 9lbs of boost, I had a flat line of 500lbft of torque at the ground from 2800RPM to near redline.

I run a sticky 315 out back and it's not enough to hold that torque in 1st or 2nd. There is really no reason to make more. However, as you pulley down, your procharger will make more torque down low. I am now making 13lbs of boost and getting about 15 degrees of timing with my smaller pulley and it's a monster.
