LT1's with Vortech Systems....
 

does anyone have pics of an lt1 with a vortech setup and aftercooler? also whats kind of power are you guys making? do you hear it wine?

anyone?

I had one but no pic's. I had the T-trim with the Vortech aftercooler. I used the 6.66 and 2.75 pullies. On a 383 with AFR 210's and a 224/236 cam, it made 13 psi and ran 10.40 at 133 mph. Through a TH350 with a loose converter, it made 550 rwhp.

im having a motor built for the car thats all forged components and everything going through abuilt 6 speed. can i run high boost like around 15 pounds or something?

In short, no.

- Yes, you will need all forged components, but you'll also need low compression. Around 8.5/1.
- Engine management becomes a problem. The stock ECM can be made to work with 15 psi, but it's jury-rigged. You really need aftermarket EFI for it to work right.
- Fuel system has to be stout. At 15 psi, you're talking 600+ rwhp (assuming decent head/cam). In that range, you'll need 2 fuel pumps and some big injectors. Perhaps even low-impedence injectors. If you run those on the stock ECM, then you'll need an impedence converter.
- 15 psi is fairly tough to get out of a centrifugal supercharger. When I tried going over 13 with my T-trim, I had trouble finding the right pullies to do it. Then, when I got a custom pulley made, I had belt slip problems. My point is that you'll run into a bunch of SC drive issues when you get much over 10 psi. That's part of why I switched to a turbo.
- Your goal should never be a boost number, rather a power number. Why would you want to make 15 psi? Isn't power our goal here anyway?

contact speed inc, they are in schaumburg not too far from you.

what about with a procharger f1 or d1sc?

Same issues.
