#113198, "boost, not turbo" Apr-24-03 07:02 PM by theallpowerfulme
ok, if you don't know what is going on in that pic, don't post here. I just bought an ati procharger with monster-ass intercooler, piping, wastegate, msd timing retard box (retards timing according to boost), and aeromotive fpr w/ mechanical gauge. All of this came off of a 383 stroker. Now I did not buy this for the rs, I'm just toying with this idea. I know I will have to get that "driveshaft" custom machined, custom brackets, and re-locate the battery to the trunk. The procharger is good for 30psi, and yes I know a low-comp. rebuild will be in order. Post your ideas, thoughts, and suggestions. TIA

go for it! then make a writeup and become a god of 2gnt. i want to see someone on the board, boosted without a turbo. it must be a very different feel with a supercharger.

My first suggestion, don't drop compression. Second get a lot of good fuel info from the turbo section if you don't know how to set up a fuel system. Or just duplicate one of the higher end fuel set ups: Adj. FPR, upgraded pumps and injectors. You may want to concider an 8 injector set up to keep driveability and idle. Third the pulley shaft, with such a long run I worry about flex. So I would have whoever is making the shaft, put a u-join in it to take some stress out of the system. Fourth, bye bye AC, and power steering most likely.

I think those shafts are run through a bearing tube so that they won't flex or have exposed motion....I could be dead wrong though.

I think you should consider the size of the supercharger. If it came off of a 383 and can build 30 psi boost, then it probably isn't ideal for a 122 and 10 psi. I'd find the model number and try to find specs for it. Procharger may provide compressor maps or something. If you are really going to attempt a supercharger install, then I think you should start with a properly sized supercharger. With some ingenuitiy, time, and money, there is no reason why you can't build a 420 supercharger system.

well, I have a p600b (http://www.procharger.com) its the smallest supercharger they make, but mine has been upgraded to handle more boost. When it was on the sbc, it was making I think 26psi, but with proper pulley diameters I should be able to find a happy medium, no? Keep the input coming.

That pic in the beginning of the thread, is that your's and is it done already or is it photoshopped? Personally here's my thought on the matter. I'm very partial to turbo's because they are much easier to upgrade, don't take power to make power, and are more efficent. In the long run I think it's going to cost you more in custom work to supercharge your car than to turbo it. However, if you're like me and want to do things that no one else has done, more power to you. I will tell you this though, if you think one has traction problems with a turbo car, wait until you drive a supercharged car!!!

that pic is supposedly real, yet nobody knows whos car it is. Def. not mine. There are two reasons I am asking about this, 1) It hasn't been done by many people b4 (apparently one, and nobody knows who it is), 2) I got a killer, killer deal on all of the stuff, mucho less than I would pay for a turbo with intercooler, piping, etc. But like I said before I didn't necessarily buy all this for the eclipse I just bought it because of the price.
