extending a SC shaft? bearing mounts?

[AleroB888]

Here's what the V6 Ford Probe guys have been doing for superchargers:









They run a countershaft across the front of the motor supported by bearings, with pullies on either side. Should be easy for a machine shop to make if you can't do it yourself. Just some ideas

That looks risky, if it's going to blow into the throttle body. If the BOV fails, it could throw a belt on either side. However, there appears to be a clutch pulley on one of those setups, which would provide some safety.

And it looks like the engine would be free to move around in relation to the blower. Other systems mount the blower rigidly in relation to the engine. Unless there is much more bracing underneath that is not visible in the pics.

Looks a bit heavy as far as extra parts needed, but if it works, more power to them.....

Yeah, they're bracketed to the top of the transmission so they move with the motor.

I've seen both setups, with the TB on either side, people seem to have no issues either way. I just posted some pics I could find easily.

I was just throwing it out there as an option cause its kind of an out-of-the-box solution which I think is pretty cool.

Personally for me I'm going to be mounting my charger either right on top of the AC compressor or in place of the compressor. I have my plate done I am working on the brackets next

OR... you could turbo it. OR use a centrical kit that allready exists and modify it to fit... Someone here a while ago was going to do this with a 3400 W-body.. dunno if it ever got finished. http://60degreev6.com/forum/showthre...d+supercharger. RSM Racing in canada used to make a Centrifical kit (very few out there)
TRD supercharger for Scion TC.

I could, and I probably will go turbo at some point, but like the OP I'm wanting to go the SC route at the moment as an engineering exercise and also as proof of concept.

[sassyness77]

Yes exactly. I dont want to use a jackshaft like the probes, i'm just extending the original shaft, building a custom bearing mount and making ducting for the intake and air flow.

I have been playing around with superchargers for the FWD vehicles for a little while now (the pic of the Vortech V-5 unit in the green grand am is mine). I still have another supercharger setup that I am working on that should have been done by now if it wasn't for the machine shop being behind on production runs. What I am working on is a redesign of the RSM kit to fix their drive shaft issues, which consists of a redesigned drive shaft assembly that uses a Eaton composite coupling, and a 6204 bearing rated to 20,000 RPM. The setup also allows the use of Vortech pulleys, so boost levels on the V-9 supercharger can be changed rather easily. I also have mounts for the both the grand am/N-body and W-body for the Vortech V-9 headunit.

A few pics of the mock up pics over the years:

















Some tips that I have found that help:
1. Start with mounting the supercharger as this will effect the length of the drive shaft and pulley alignment.
2. Use wooden dowel rods, card board, PVC pipe and thin gauge aluminum that can be cut with tin snips to help with mockup of the drive shaft.

I am ancious to see how the Centrifical kit works, i know a few of the 3800 guys have had great success with it. more compact and easy to IC.

Anyone else notice that this car has not 1 but 2 BOV's?
