Where can I find a supercharger new or used? bbsports@msn.com

Downing Atlanta makes the only bolt on supercharger for our cars. They use the Eaton M45 if I am not mistaken. So if you are creative, you can make your own. I would not pay more than 800 bucks for a used one, However on ebay, I just saw one go for 1800 bucks with well over 150K miles. Honestly, I would put a s52 in the car. More power for the money.

God luck finding anything close to a full kit for $800, and for those who want to keep the balance of the 4 cylinder weight, there's nothing wrong with keeping your m42.

DASC kits used the Eaton m62 similar to the merc c230 unit.

is it the idle control valfe on the top?? if so where does the hoes go that curves to the left side??

It doesn't look like his is connected yet. On the original kit, it plugs in where the original ICV connected. If you emliminate the mess under the intake, I believe it plugs into a connector on the boot between the throttle body and the AFM.

thank you for the reply.. I will be doing the same job next week actually.. I had a eaton m90 thunderbird cs kit..

I have two questions: 1) where does the pipe that goes into bypass walve comes from?? I mean where will I I take the boost for bypass??

2) It is possible to put a boost gauge on a SC system?? If possible where and how??

thank you for your anwsers..

There are boost/vac ports on my intake, icv goes to intake boot. Boost gauge is easy, tee in anywhere after the point where s/c pressurizes air.

I'm probably misunderstanding your question but the ICV outlets before the SC but the bypass would be open while idling. Under the ICV is the bypass path. The bypass is external on the SC Downing Atlanta did. I think some newer units have it in the SC housing.

here is what I am wondering.. I put ared arrow on the pipe and I am wondering where it goes...

and here is the SC kit I will install..

doitover · « **Reply #9 on:** July 18, 2012, 10:24:16 AM »

That looks to me like a vacuum line that is used to control the bypass.
It can tap into any other vacuum line. I'll try to get a picture of where
mine goes later today.

actually I saw a photo on the net that show the pipe I showed goes somewhere just after the throttle body.. but I believe it should go somewhere in the intake manifold.. I am really confused....

doitover · « **Reply #12 on:** July 19, 2012, 09:32:17 AM »

I didn't get a chance to take a picture yesterday but I did have a look. It does go to a port on the throttle body. That is correct as you want it before the supercharger.

here is another mystery

what do you mean by It goes to a port on the throttle body

ı saw it goes somewhere between throttle and supercharger.. never saw somewhere on the throttle body.. Luckly I still have time to do it.. tomorrow I am starting to make the flanges for supercharger.. but not more than one or two days.. If you have a chance to tka a picture during this time I would really appriciate it..

by the way if you have a boost gague I also kindly want its connection photos..

thank you for your help..
