toastemcutlass Posted April 7, 2003 Report Posted April 7, 2003 http://mae.wvu.edu/~mhawkins/super34.htm he made his own computer wtf. i wish i was that smart. Quote
slick Posted April 7, 2003 Report Posted April 7, 2003 Very smart man. He must of sat down with the computer, and figured out everything he could about it, and using some good programming skills, loaded the program onto the computer. I know how to program, but i couldn't image doing something like that. Quote

Redfox340 Posted April 7, 2003 Report Posted April 7, 2003 I've seen that, and thought you guys knew about it. I e-mailed the guy a few months ago asking specific questions on the make-up and programming for a boosted DOHC and got no answers. Bummer... plus, the lower intake need to be smaller (in height) since that M62 supercharger is sitting high to fit under a stock hood. - RedFox340 Quote
GnatGoSplat Posted April 7, 2003 Report Posted April 7, 2003 Awww heck, I knew about that project way back in '96! Well, maybe not that long ago, but pretty close. It's been posted around on some of the old forums that were around 5yrs ago. On a 3.4 DOHC, I wouldn't bother with a roots blower, centrifugal would be the way to go due to space constraints. That, plus a centrifugal is more efficient, or so I've heard. Quote
JS91Z34 Posted April 8, 2003 Report Posted April 8, 2003 If I went with the roots style s/c I would definitely have to get a different hood! Quote
brian89gp Posted April 8, 2003 Report Posted April 8, 2003 na, a csc has lag like a turbo. a roots blower is that, a roots blower. If i had a choice i would pick the roots and mount it in place of the a/c system then do all the ducting work. Quote
GnatGoSplat Posted April 8, 2003 Report Posted April 8, 2003 Why would it have lag? It's already spinning??? Quote
skalor Posted April 8, 2003 Report Posted April 8, 2003 na, a csc has lag like a turbo. a roots blower is that, a roots blower. If i had a choice i would pick the roots and mount it in place of the a/c system then do all the ducting work. A CSC doesn't have lag like a turbo car. I will say that it is not instant full boost like a roots style, but it's much more linear than a turbo. It's definitely a step between the two as there are factors that link the CSC to both the roots and a turbo. The adiabic efficiency of a CSC is much better than a roots, which would lead to lower air intake temps. Plus it's much easier to plumb an intercooler, which would lower your air intake temp even more. You can run a lot more boost than would be able to with a roots(assuming the engine can take it).

slick Posted April 8, 2003 Report Posted April 8, 2003 Where can you find csc's at besides for brand new or ebay? Were there any cars that came with a csc from the factory, or just turbos and super's? Quote
skalor Posted April 8, 2003 Report Posted April 8, 2003 The only car that I've ever heard of that you could get from the factory or least a GM dealer with a CSC was a Corvair in the late 60's. Otherwise it's pretty much all aftermarket. Anyone else know of a factory CSC??? Quote
brian89gp Posted April 8, 2003 Report Posted April 8, 2003 Yes a csc is more linear but it is still quite peaky in the airflow. After all it is basically a compressor side of a turbo that is belt/gear driven. Maybe i shouldn't call it lag...how bout dead spot in the boost. The way the impellers in both turbo's and csc's is that they have to be spinning at x amount of speed before they start compressing air (those wonderfully complex compressor flow charts). This is probably a bad analogy, but a turbo is always spinning, just not fast enough to produce boost. Same with a csc. While the effect is far less severe with a csc it is still there. Now a roots blower, it doesn't compress anything, it only moves air. Thats why there isn't any lag and why it is used so much in drag racing. Quote
skalor Posted April 8, 2003 Report Posted April 8, 2003 You're absolutely right about everything you said. I just wanted it to be clear that a CSC is a good median between a turbo and roots style blower 8) Quote

GnatGoSplat Posted April 8, 2003 Report Posted April 8, 2003 Where would a twin-screw Whipplecharger fit in? Quote
GnatGoSplat Posted April 8, 2003 Report Posted April 8, 2003 I did some searching and it's actually a bit different than a roots charger. http://www.sportcompactcarweb.com/tech/0107scc_garage/ Quote
