Well I will tell you that you need thicker then 5/16 plate for the bracket.

I'm into this issue right now. It looks like I'm adapting a 10 rib LS pulley onto a dual keyway ATI Chevy front damper. At last PRI they were all hot to custom build a damper for my needs, ie integral 10 rib and 60-2 reluctor ring. Later on the phone, oh yeah, that will take 8 months and cost a fortune. Brackets I'll just build. 5/16" would likely only be correct if it was widely spaced, boxed and or braced. Starting with 1/2" would be a better starting point, but then we don't know your real boost or application targets.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

1/2" at least, you can trim some weight off the ends but the center (longest open area) must be really stiff.

Kit pics. The blower mount, which includes the idler pulley, is quit involved - hence the $. Just the tensioner alone would be tuff to duplicate.

The adaptor you see ( at the bottom of the kit pic and on the front of the engine adapts from a mopar to a chevy pulley.

Notice the kit also includes the H20 pump because it is included in the mounting.

Do yourself a favor, bit the bullet and buy the kit. Alternator shouldn't be a problem as it is on the right side. P/S sits below the blower mount on the left side. I went to manual steering, so no problem for me. If you intend to run lots of boost ( over 15 psi ), you will need to run the belt tensioner almost to the stop ( use all the tension spring ).

Thanks for the replies everyone! PM's sent to 80arrow and spareparts .
Crizila, thanks for the pics of the blower setup. I have a couple of questions on it if you don't mind. When you say the H20 pump is included in the mounting, is there anything special/custom about that water pump to allow for the blower bracket mounting? Also, the crank pulley adapter piece, does that fit hub centrically into the balancer and hub centrically into the blower pulley or does it just get aligned by the bolts? I ask because I ran a custom procharger kit on a Chevy LT1 made by a now defunct company where the included spacer/adapter piece didn't have a hub centric end for the blower pulley and I was never happy about that. I actually had a CNC adapter made to align it up.
A few questions for the guys who say to run as much SBC stuff as possible, are you referring to the bracket too? Has anyone tried to modify one? My concern with that was that it could be vastly different in where the bolt hole locations are, seems like it could require more modification than it's worth and may be easier just to cut my own out.
Point taken on the 5/16ths. I was thinking if I made it two pieces and connected in the middle with spacer blocks, but if I make a custom bracket I might as well just use 1/2. The last blower setup I did on a 96 Impala SS used 1/2" 1 piece bracket and I welded up some support bars to bolt from from the bracket to the heads/block. it worked great at 15psi/670rwhp.
That tensioner looks like a Procharger one. I have never had great luck with them, they aren't bad but they have less travel than some others before the springs bind. I have seen a few setups running 15+PSI using Dayco 89401 and good belt wrap. On the last procharged car I had, the kit didn't use a spring tensioner and just had an idler pulley mounted in a slotted hole on the bracket that the tension could be adjusted with. On a 12 rib belt, I was able to run 14PSI at around 590rwhp with no belt shreds or slip. It was a VERY simple setup, but it worked (probably thanks to the 12 rib belt). For now, I don't think I'd be running more than 6-8psi but I'd like to build it capable of more if I can.
Honestly, the Supercharger Store's price on the complete kit seems like a very good price. It's just that I don't need more than half of what comes with the kit. I already have the D1SC, pro-flo bypass, A1000 fuel pump and I wouldn't use their piping as I wish to run the intercooler I have here as well. The price on just the bracket/pulleys was just too high for my budget. 1300 for a bracket, tensioner, blower pulley and crank pulley plus adapter is steep.
