Steel J-Bracket for procharger... which company!?
 

So I was looking into the steel J-Bracket and I see two company's mentioned while searching. Automotion which I haven't seen referenced for about 5 years, and this company that has one on their website.

Is one better then the other? Did they change company names?

Should I just order it here?

Whats wrong with the aluminum one?

Flex.

How much boost are you running? Seems like a crock to me. I'm sure there is SOME flex, but more from the spacers than the bracket itself.

im not seeing any flex in mine im just saying that why you would want a steel bracket

Oh I agree on the reasoning behind it, I just don't see the bracket being what flexes. I see the spacers and bolts flexing before the supercharger bracket itself.

Thats what I would think too. Thats a serious piece of aluminum compared to the studs in the alternator and aluminum stand off nuts.

Seen a few posts of people saying it helped so I figured while I'm in ther eputting it all in may as well get the better one?

I called True Tech last year to order one, and they didn't have any made at the time. They took down my info so they could call me once they had a new batch made up, apparently they never made any as they never called... lol I'd be curious to see if it helps. Bob

I just bought one recently from True Tech, it seems very nice.

I had two SDCE setups, one with the aluminum and one with the steel bracket. I switched between them a couple times and there was never any difference I seen really.

With the stock 6 or procharger 8 rib where you have to tighten the crap out of the belt it may help some.

A little hint is to take the aluminum bracket and drill another hole and use an extra bolt to hold the blower on, you dont even have to countersink it. That really helps out the stock J-bracket.

we make a steel j bracket for the f body cars,here a couple pics of the prototype we made a while back.the stands are also 4130 chromoly

How much?


FWIW, a nice brace from the block to the J bracket will pretty much eliminate flex. Its cheap too.

i would like to know

that looks bad ass!! how much for the bracket and cog set up??

The true tech bracket has served me well for many years.

Nice Shawn, for some reason that looks very familiar...

Is that bracket spaced out more than the factory ATI bracket? The cog looks quite a bit wider than my 8 rib pulley, and mine *almost* touches the alternator pulley as it is, if the blower came forward anymore it would be inside the radiator...

Yes, it's considerably further out than an 8rib setup. The whole assembly was purpose built for the cog drive.

The j bracket normally sells for 139.95,if i could get orders for 10 or more i would be willing to drop that down to 120.00,the assembly with the stands,and hardware is $400.00-the stands can be made for 6,8,10 rib belts as well as a cog setup.

Oh okay cool... dream crushed!

I'll check on the price for the cog setup-that one is pricey due to the fact we used a sprag pulley on the s/c

hmmm.....

Buzzard Alert
Anyone have a used J bracket they want to sell? PM me

Can I order that j-bracket with 6-rib pulleys?

Probably, but with a 6 rib you'll slip way before the bracket flexing becomes an issue.

I ordered the bracket last week. I asked if he had the standoffs and he said he just sold the bracket. I didn't ask about pulleys, but I am guessing he just does the bracket for existing users who have everything already?

I swapped out the aluminum for the trutech bracket, picked up 2-3 pounds of boost as shown on the gauge, im assuming from less flex and thereby less belt slip.

I've got a homemade steel j for sale.. currently on my car... PM me

Any pics or ideas on this?

Shawn, you have a PM.


TopFig

Shawn, you still have a PM.

Just wondering if this was still available for a 10 rib belt driving an F1R? Do you make a 10 rib pulley that bolts onto the crank pulley (ATI crank pulley). Thanks

so is the steel bracke treally that much better than the stock procharger bracket? stock procharger is cast right? or am i thinking about vortech?
cant rmember right now:chug:

Shawn, can you pm me about your steel 8rib setup? thanks

No the stock Procharger bracket is machined out of a .75" thick piece of aluminum plate, definitely not cast.

thats what i thought. i must be thinking vortech. remember seeing a cast bracket on a c5

Damn that last pic with the cog set up looks sweet! Anyone know how much that will cost? Also if I only plan on running 9-10 psi, will 6/8 rib pulleys and an alum J bracket suffice?

Yea jason. For your goals a standard J-Bracket in a 8rib setup will be fine. I wouldnt run a 6 rib setup though.

Dang, I have all 6 rib pulleys.

Plus my J-bracket has the Chevy Chad mod where one of the stand offs is milled down to include an extra pulley for more belt wrap around the head unit pulley. I wonder if that will make using a 6 rib system acceptable?

Maybe. Could an 8 rib belt still fit under the pulley? What about swapping off the pulley for a thicker one? I have a couple 8 rib blower pullies if your in need. I have a 4.15,4.00 and the 3.7 thats on my blower now will be off soon. I also have a 3.70 in 6rib. I would try to figure out an 8rib setup.

The thing is if I try to put a thicker pulley onto the stand off that is milled down, then I need to mill it down further to get it to fit. How much would you sell that 6 rip 3.70 pulley for? And if I do figure out how to get the 8 rib pulley to fit, then I also will need a 8 rib idler pulley and a 8 rib stand off pulley (I need three pulleys for my brakcet 1-procharger, 1-idler, 1-stand off pulley).

Looks like this:

I was lucky and bought one off a member that was steel. It looks like someone just took a stock aluminum one to a machine shop as a template and told them to make it out of steel for them.

$50 bucks? Its bran new and never used. They sent me the wrong rib setup lol

Sounds good. What do you think about that set up I pictured?

Its a start. Seeing as how you already have it and isnt gonna cost any more money to set up I'd try it. It looks like its going to have a lot of belt wrap which will be your saving grace. My only concern is that its a 6.2L and shes gonna make some nice torque. Try it out, get her running and work out sll the bugs. You'll know pretty quick if its not gonna work lol. Let my know when your putting her together and I'll help you out. I musta had my car all apart a gagilion times lol

so is this a cog only from va speed or do they offer an upgraded steel j bracket and tensioner setup?

i think they sell bracket seperate and as kit.
what is the thickness of the steel bracket?

Shawn, can you pm me about your steel 8rib setup? thanks
