My cost from Vortech was $ 147.00 took about 3 weeks for them to do, Talk to a guy named Jamie in tech. Best 147 i've spent yet for HP gains!
Ryan, Keep us informed on the 2.87" swap I've though a lot about that!

 

has anyone tried swapping the cogged pullies instaed of the 6 rib pulley?

If you stayed with the larger 3.33"pulley and then you switched out the cogged pullies, you wouldn't run into as many belt slippage problems...maybe.

 

I switched cog pulleys..I had a custon 34 tooth [ instead of the stock 32 tooth ] made for me . Im running the 3.12 serp pulley

 

I think auto specialties makes a 34 tooth cog for vortech applications already.

 

I got mine from Vortech . It was about twice as wide as needed . I had it cut and milled to fit . I think it was for Vett kit

 

Anybody upgrade there Vortech Blower Trim, still on stock internals ?

 

The shop got my motor back in and running good . SGP did a great job on the motor . They dropped the compression to 8.5 to 1 with CP piston this time . This is going to be one stout motor . It feels stronger even with the lower compression . Didnt feel any loss from it . I only went to 1/4 throttle to about 4000rpm's was running pretty lean and I saw 4psi so I didnt try to throttle it up any further . Im glad I didnt because the blower started to whine real bad . We checked the oil feed and return lines and they are fine . So the blower is going back to Vortech . The SGP valve body shifted great and is going to help alot . The 31+12+4 intercooler and 3in. pipe to the TB is going to help air flow a great deal . Cant wait to see what she will do . Now if Vortech holds to thier said 7 to 10 day turn around [ lol ..took a month last time ] it shouldnt be much longer

 

NIce to hear you got it almost worked out, I have almost the same setup as you except maybe you have a few things you maybe keeping secretive
