Crank Support? Aj 481x Screw Blower

Is A Support Necessary When Using A Psi Screw On A 481x? Kinda Gets In The Way And I'd Prefer To Run Without It... Any Opinions?

 

We ran an RCD support with our roots. not sure on a screw

 

We Got It On Still, Dont Really Think It Does Much, Especially When The Bolts Get Loose. It Sure Makes It Hard To Change And Or Tighten The Bottom Pulley

 

And change blower belts....

 

(6) 3/8 bolts, quick release clamp on the pump,
two bolts on the idler,..change the belt,..wow whats that take

3 minutes tops,...

Buzz kill.

 

I'm Putting The Car On A Diet Also....if It Isnt Doing Anything Up There It's Gone

 

I have an old BACMAN support on one motor.
I love the concept!
Buttttt,,,,
I wonder about this, why do we line bore/hone to get within a thousandth of being inline. Then we bolt on this bearing plate 5-6 inches away and expect it to be inline and helping???

Maybe it does, but doesn't anyone else wonder about this?

 

Psi Manual That Drazy Wrote Says Everything Out There Is Really Too Weak To Do Any Good
It's Not Hurting Bearings Now Sure Wouldnt Want To Create A Problem

 

Shawn,
Those Crank supports sure do make it a little tough to put the big ol` "dinner plate" on the crank hub...

Ive seen a few guys NOT run one with no problems... But all combos can be a little different. Does it really save much weight??

 

Jason I Think I Hate Tightening That Lower Puller With The Support More Than The Weight Concern... But It's Cheaper Than Buying Titanium Parts!
