    raven, it's possible, Lancia have don it, and may other have don it too.

    And that centrifugal clutch device, I was thinking of that first but I came up with a better option..

    And I'm not thinking of to high boost max 2 bar (20PSI)
    But with twinturbo and a sc working nice, that will get a real good engine even in low and high rpms..

    but I'm not sure what to do...
    I might just go with twinturbo...


    Have a nice day..

      Nobody said it was impossible, just pointless. Check your math again....2 bar = ~30psi, not 20. Running 30psi on a street car just isn't feasable, which is why the twin-charge concept won't be worth the hassle. Besides, with today's turbo technology, you can run 25+ psi on turbo alone. Lancia used the technology because they were limited by the rules to a certain displacement, so the higher boost presure allowed them to make more power.

      Running 15psi on one of these engines will make more power than you can use in a FWD anyway, so anything more is a lot of hassle for no benefit.

          i dunno about that, eer her about what a 400hp a 600hp and a 80hp supra have in common? they all run 12's!

          i forget where i got that but i thought it was funny.

            That's because anymore HP won't make the car any faster without traction. Same thing would happen with one of our engines pushing 20+ psi....without traction, it does no good.

              I thought it was a joke, cuz according to ricers all cars out of japan run the 1/4 in the 12's
              I wish 10% of the people on the road knew how to drive

                Around here it's "what does a 500 and 1000 hp supra have in common? 12 second et"
                Perfect example of traction being a problem, of course It's got a lot to do with driver too. The IRS in a supra doesn't lend itself well to drag racing, and neither does a first gear that ends right before the 60' mark.

                But of course same point, 20 psi in a 660 in a front drive car and you're not going to have much fun on the streets. It would be a different story in a fiero though.

                    4wd is a whole new playing field when it comes to traction, I bet you can make some nice launches... is this in like an S10 or something?

                      Today begins the process of another engine conversion. Here we will be installing a 3800 Series 1 Supercharged engine from a 1995 Bonneville into a 1988 Fiero with a 5 speed 282 Getrag transmission. The reason for the series 1 is that the customer had bought an engine on Ebay that was supposed to be a 2003 3800 Series II, instead received a 1995 ( never installed ) Series 1 with no accessories, no
