twin screw accessory configuration

[lifespeed]

I'm at the point where I need to pull the trigger on the supercharger purchase. I'm going with Kenne Bell 2.8L for numerous reasons. I believe there are two basic belt configurations for Mustang, dual belt (Cobra) and single belt (Mach 1 supercharger add-on kit). But I could be wrong.

Given the different accessory drives between the Mustang and Marauder I will still need to get some eaton swap accessory components, probably the alternator bracket at a minimum. I would like to understand which supercharger configuration from Kenne Bell, Mach 1 retrofit vs Cobra, is most appropriate for the Marauder application. Are the snout lengths the same for the two applications? It might seem simple enough to ask KB, but they don't really want to entertain a non-standard application like the Marauder. Seems best not even to discuss it with them.

I have a 2.6 Kenne Bell installed by Matt @ Performance Evolution. You may want to give him a call to see what he used. Worth a try...

The 03/04 Cobra configuration is what you want, doesn't matter what s/c you go with be it Eaton, Whipple , or Kenne Bell.

Did it previously have a boosted set up, or was this a virgin build?

Would you post a clear picture showing your accessory drive? Close up of the alternator, tensioner, blower and water pump would be good.

I hesitate to call and take up his time with questions when I won't be doing business with him given we're at opposite ends of the country.

There are dozens of pictures of eaton swaps on this site at your disposal 24/7

Same thing.

Here is an eaton swap thread (http://www.mercurymarauder.net/forums/showthread.php?t=60366). Still wouldn't mind seeing the kenne bell implementation.

I don't see a kit for the mach 1. But you can't go wrong with a cobra kit and the eaton swap brackets from Jerry.

It's the exact same thing, only with a KB on top. :confused::confused::confused: :confused::confused::confused:

It's a long story, but KB makes CARB-legal kits for Mustang Mach 1 and Mustang Cobra. They have different accessory drives, with the cobra being the more traditional eaton-swap style with a dedicated blower belt. This may mean the blower snout length is shorter for the Mach 1 single-belt drive.

The Mach 1 kit did have a shorter snout and a single belt, but that kit is discontinued.

I think for $6K they'll sell me whatever I want, at least that is the impression I got when I spoke with them. Which may well be the CARB EO number blower for the Mach 1 with the longer Cobra snout. Or I may have to buy the snout separately, who knows?

I just need to be sure of what I am asking for and why. I guess trying to run the blower off the same belt that drives all the accessories (like their Mach 1 kit) is asking for trouble. And while they may have made it work on the Mustang, it would require I invent such an arrangement for the Marauder timing cover, assuming it is even possible. It sounds like Cobra drive setup is what I want.

I know it's all personal preference, but I've used Kenne-Bell once and only once due to it being almost impossible to get a hold of their tech support and when you do, they act like all questions are idiot questions.

If I did it again today, it would hands-down be a Whipple. I've driven the same car with a factory unit, then a KB and then the Whipple. The Whipple was far superior.

Interesting feedback. KB has a good reputation for paying attention to airflow all the way through and getting high power at low boost - an indicator of efficiency and that their approach works. It sounds like their tech support could use some work.

But I have heard good things about Whipple as well. Of course, there is an added complication of California smog which influences my choice.

There is some confusion in this thread.

All 03/04 Cobras used two belts. One for the S/C and alternator and one for the water pump, power steering, and A/C compressor. This setup used a pullet bridge and located the alternator down low. You could use this setup, but you will have to notch the frame for alternator clearance.

The other option is to use Eaton swap brackets such as Jerry's brackets. This relocates the alternator in a reverse position and all accessories use one belt, while the S/C has i'ts own dedicated belt.

The 3rd option would be to use a single belt like the KB Mach1 kit used. If you can get the kit.

I never saw one, where is the alternator in that set up?

[Blown3.8]

Just found this. http://www.mustangandfords.com/how-to/engine/m5lp-0412-the-kenne-bell-supercharger/

But I would go with the terminatr kit to be able to get stuff that is still available.

YES it relocates it backwards like the eaton swap kits do.

Great link! I know what the Eaton swap looks like, but it is nice to see the KB approach. I'm still wondering if there is a potential disadvantage to running a single accessory belt.

I would prefer a dual belt setup , if a single belt setup throws a belt your stuck wherever, with the dual belt setup the blower belt can fail , and you can continue to drive the car, plus the single belt setup is under a heavier load spinning the s/c and the other accessories on a single belt.

Off the top of my head the dual belt sounds sturdier. But the reality is the supercharger draws far more power than any other accessory, so that may not be that significant.

Possibly the biggest advantage of dual belt is it would be easier to switch to 8-rib for added margin against slippage? You wouldn't have to come up with an 8-rib A/C clutch and power steering pulley.

I would go the dual belt route , converting to an 8 rib setup is easy , i have the part number for the ac pulley, and the power steering since i did an 8 rib setup.

And to further muddy the waters, it appears that KB offers the parts to make the single belt an 8-rib setup!

I guess you have a centrifugal so the setup is different. Did you use a single belt, necessitating you convert the AC and PS to 8-rib? I don't understand why 8-rib would be used on the accessories if the SC has it's own belt. The eaton swap configuration has the SC on it's own belt, so only the crank and SC are 8-rib.

The centrfical s/c applications use a single belt , i converted to 8 rib to help with belt slip , i have sold my Vortech setup in favor of a twin turbo setup I'll be fabbing up.

Turbos are the best, although practical considerations preclude me from considering them for my car. I had a twin turbo setup on my waterski racing boat that would stand the boat up on the propellor. It was quite the ride.

Did you have any slip or belt throwing issues with the 8-rib? How many miles per month did you drive it?

I had stupid belt slip even with the 8 rib setup, then i went with the cobra 96-99 front cover which has a 3 bolt tensioner versus the single bolt marauder cover , still had belt slip until I went with the A&A grooved pulley (basically a ricard racing pulley) that finally stopped the belt slip entirely, never had a problem throwing belts it's aligned perfectly.
I have about 3K miles on the new setup.
