Crank Support help

[allshownogo]

Can someone using a procharger crank support explain to me :confused: (or post pics) of how they work?? Do you use a different pulley or is the shaft just bolted to the front of everything else?? Any help... Thanx.

Heres pics of one on a SBF w/ a reverse F-2. Basically you have a mandrel that bolts to the face of the balancer sandwiching the blower pulley. Then the bearing and support plate that it bolts to. Reverse setups have the mount built in. Standard setups have an independent mount for the bearing plate. All I have here is a BBC revese setup not a standard one. But I am getting ready to do a SBC crank support soon if you need more info.

Thanx Jake... that answers most of my questions. Think the mandrel could be aluminum??? And how thick do the motor plate and bearing plate need to be?? Appreciate it.:)

Given that the plate they use is 10 gauge or less to bolt the bearing to I would think flex could be an issue myself. I like how ASSC does there SBC support. Its machined out of a thicker aluminum front bearing plate. The one for the SBC I am doing is gonna use a front plate of aluminum that 1" thick. This will house the bearing. I am also gonna make the madrel out of aluminum myself so we'll see how it goes.
Here's a pick of a mandrel I machined. http://jakesperformancefabrication.com/gallery/v/1321/Hub+and+fan+shroud+044.jpg.html
It was intended only to drive a vacumn pump. The guy that owns the Supercharger Store saw it and commented how he thought it would be good enough to use as a crank support madrel. So I am gonna run with that and try a similar design as a crank support.

Here is a link to the bearing support (home grown) I created for an F3 on a 8.2" deck SBF.

I need to find a good home for the F3 and custom setup - going Reverse Rotation F2 to better match the 359 CID motor...

Jake-

I am in the process on purchasing an F2 or F3, and I will definitely be in need of a crankshaft supprt. Did you ever finish the one you mentioned previuosly for a SBC? If so, do you have any pics?

We are in limbo right now. May not take the time to build it before we get it running. If we get around to it before so I will post some pics. Sorry.

Food for thought on the plate which the crank support bearing is mounted on. When I designed the crank support, we intentionally went with a plate that would have some give along the crank axis. The thought was that if the bearing seized to the mandrel it wouldn't be as likely to take out the crank thrust bearing..

Aluminum or steel? I just finished my support assembly and everything is aluminum. The plate is 1/4". I'll post pics soon.

The original design was 10 ga or 8 ga stainless steel..

Does anyone make a crank support for bbc that works with ATI brackets?

Procharger offer's a kit that bolts on a reverse setup and they offer a universal type stand alone kit for the standard mount styles.

OK it's finished... finally

Kick ass!! Looks nice! What bearing did you use?

[Mike Coffey]

Work of art!:cool:

Nice work as usual Brent, But one question, If you are in BFE, where the hell am I?

I used a bearing I had in my shop that originally came from another profject. It was out of a primary support plate for a custom chopper I did some repair work on.. It's designed to handle a side load and the rpm. All those high speed bearings are expensive and this one was still good soooo.... Thanx for kudos!!:smt038

Cool! Yep that bearing is about 50+ bucks.

I think he told me they were around $300 can. each??:confused:
