Oh yeah that's why I assume a lot of the c5 guys move their racks forward.

But this is a c6 kit. Says so in the title.

C5s suck anyways. I get pissed off everytime I drive mine..

The engines are in different locations for the ZR1. I can see the 12 rib working with later generation engine location.

I dont know exactly the differences but- 09+ torque tube is 1.5"~ shorter, but trans/diff are in the same location. Bell housing is different as well, and ZR1 engine mounts are ZR1 specific.

Some of you may have noticed that there are two sets of engine and diff mounting holes in the 09+ year model cars.

Through these differences, you can fit a 12 rib.

The 12 rib will not fit on an 05-08 car, to my knowledge.

Louis Gigliotti

Someone needs to fact check the engine location, because I have not. I just know from working on all of the variations. I have not taken a measuring tape to anything but the torque tube.

Blackonblacksls

Quick google search tells you the different mounting spots are because the same cradles we're used in he Cadillac xlr

Blackonblacksls

I wouldn't think things like headers and mid pipes and cat backs would be interchangeable between all models if the motors we're in different places..

Not to mention as tight as the body is to the bellhousing I don't really even know how much it could be moved back??

Louis Gigliotti

The entire torque tube Is shorter, significantly.

I've not taken the time to find out where the differences lie, in the rest of the setup. Bell, mounts, cradle...

Damn ppl are slipping a 10 rib? I'm
Guessing the full racers with 25 + boost maxing out the blowers??

Ive never seen my YSI slip with a 10 rib.. 2.75" upper and 8" lower to 7200 rpm, constant KPA gains all the time.


If a 10 rib is slipping, there is something else at play. Bad bracket design, blower creating to much drag, something... 10 Rib is plenty for these smaller blowers. I know at least one guy driving a F1X with a 8 rib and making over 1100whp without issues through a auto using the Cartek bracket.


As far as a 12 rib setup goes.. Not sure how that fits on a C6, not sure how you would change the belt. You can move the steering rack forward though, many of us did it with the C5's to fit 10 rib drives and actually be able to change belts when needed. Its a rather simple process..


Remove the rack, Cut off the forward mounting tabs for the rack, make some new tabs from plate steel and bolt them to the front of the rack, install a spacer behind the rack and the rear mounting tabs to push it forward to the new steel tabs and bolt in the rack..


This guy showed exactly how it was done, a good "how to" for people.

The 12rib system is designed for those goes well above 1100hp.
Now with people pushing F-1X's to 1,200/1,300/1,400/1500rwhp.
Getting as much belt traction as possible was a design factor.

It could be a 8 / 10 / 12.
However since the 12 fit fine, we went with that.
If a person wants to run their own 10rib, and blower pulley thats cool.
We will only be doing the 8 and 12 due to availability.

SquatchMachining

I agree that it is a great idea as long as it fits and is serviceable. In theory it should not be any more expensive than a 8 rib. A pulley is a pulley is a pulley... The amount of extra material and time required to machine is negligible, you are talking a few bucks and a extra 30 seconds on a CNC lathe.


What will these "race kits" be priced out at? MSRP of course and minus the blower head?

Only reason I'm not super excited and possibly looking into this is I'm not moving away from a cogged DD setup. Way too many issues without it. Looks like the 12 rib moves into the cogged area, which means 4 rib for accessories, which can work ok on a race application, but for a daily driver I'm not doing a 4 rib accessories drive again. It was painful to deal with. This sounds like a great race setup for 1400+rwhp cars, but I'll stick with a 10rib/cog if it was a street setup. I would still take a setup like WhiteLight over this IMO.

I dont think i can even fit a 12 rib on my 08 my 10 rib Crank pully is a TIGHT fit... i dont see 12 rib fitting. The rack would have to come out every time a belt needs to come out. my next step for belt life.. will be a th400

Unreal

I think they are adding belts the other direction. That is the only way this works. Basically filling in the area between the 4 rib ac belt and main belt with ribs. Same place ECS adds the cog setup.

0ProChargerTech

OK,.....

For those that keep asking YES, the belt can be changed with ease.

- You don't have to remove the blower to change it
- The race is in the stock location

Just unload the tensioner (below the blower) and the belt comes right off.

In high load testing we have had NO issues what-so-ever for the accessory drive, in high heat with AC on, high load (alternator), etc.

Has anyone installed one of these 12 rib setups yet?

Is this still active ?

No. It's a 2-year old thread and the OP is no longer a forum vendor.
