I purchased my procharger d1sc set up a week ago, but when I asked for the 12 rib upgrade, they said that they didn't have one listed for our cars. How did everybody else get theirs? Do I just have to call procharger and get it from them? Also, what size crank pulley do I need?

 

I have a F1A 12 rib kit installed on my 89 camaro. The brackets are just a sbc kit not just designed for the camaro, I also then have the relocation bracket that bolts onto the head to lower and move the charger out to clear the hood. If your interested i have the brackets and steering pump for that set up Im going to a manual steering rack.

 

I ordered mine throught Lonnie P. http://www.lonniesperformance.com/

Std crank pulley is 7.65"

I upgraded to a 8" or 8,25" can't remember

 

Procharger has them, lot of money. Iv heard the 12 rib is a tight fit at best.

 

Looking at my reciept/packing list and the 12rib stuff is packed at procharger so call them and they can set you up with the stuff you need, basicly the pulleys and som bolts.......

and yes its a tight fit with 12rib

 

So would these 3 parts complete my upgrade?

I'm running 12 rib belt and two v-belts plenty of room up front.

 

There are two option.

Std chevy kit or for a serp.setup.
With serp.setup ( so called TPI kit for thirdgen) its a tight fit with 12rib.

Will check the part.nbrs later today..........

 

here are the partnbr I got.

Double check since its been 9years ago...

DC009A-12 crank pulley
DM002I-7 adj. idler bushing
BO06CI-56SS Adj. idler bolt
DC004A-12 3" OD Idler with bearing
DC003A-12 2.3" OD Idler with bearing
BO06CI-48SS Idler bolt
DM002I-1Idler bushing
BO06CI-40SS Bolts
DPxxx-12SC Blower pulley ( should be a offset if using std tpi kit.)

 

Thanks for all the help so far. I called procharger today but didn't have any luck ordering it yet.

 

Would I need all of the idler parts from them? I am going to be adding a dayco tensioner onto the main bracket as a few people have done on here.

 

No, I guess not, depends on how your planning to use. There are a few diffrent way of doing it.

I use one Idler on my spring loaded setup.

 

I never had a problem ordering pulleys or belts before.

For my tensioner setup I used no extra idlers and rev to 6400 no problem so far. You might be able to get away with the 8 rib and spring loaded tensioner. How much do you plan to spin the d1sc?

 

Probably no more than 6000rpm

 

Try doing it with a cog setup using ATI's sprag clutch pulley on the blower...

Anything other than the standard belt setup gets very tight on the radiator with the serpentine TPI setup.
