I'm actually in the process of testing one out and will report back with it after I've put some miles on the car with it on.
Well it does not say if it is one from the KARMEN batch or if he has gotten a 62 mm sc pulley from somewhere else. As Rudy is the magician and has connections I took it for granted that he was talking about another one. Heck, he may even have made on himself.

Re: SRT6 62mm Supercharger pulley??
I got the following information from the seller:
Hi There, 10 months of effort was put into designing this pulley, hours of testing and lots of money.
The 65mm(code3) pulley have thickness issue inherited from its original form, the OEM. It is essentially an OEM pulley with modified grooves. Not a whole lot of engineering going on. The 65mm has a wall thickness of 1.7mm and can't go any thinner.
This pulley, the Karmen Pulley, is a new born. It only uses the OEM pulley as a reference for fitment. It is design to use smaller bearing ***** for increase speed and with smaller bearing outer diameter to improve wall thickness. This leaves the wall with plenty of thickness to work with. The inner bore of the Karmen pulley is 47mm and the outer diameter is 62mm. In radius they are 23.5mm and 31mm respectively. The bottom of the grooves is 3mm lower than the top. So the wall thickness is 31 -3 -23.5 = 4.5mm. Problem solved. The idea here is simple. To make the pulley smaller, we reduce the outer diameter. To properly reduce the outer diameter, we have to reduce the inner diameter.
Warping and wobbling: The Karmen pulley doesn't cut corners by using AC compressor's clutch plates that are in production. The AC compressor's clutch plate (armature) has a strong tendency to warp and causes wobbling or rubbing against the magnetic clutch. The material we use for the clutch plate is Grey Iron. It is as tough as a brake disc. It surface is as flat as can be. It is guaranty no wobbling and rubbing!
I'll make you a great deal plus a 3 months warranty. If I will make more of this, I will extend the warranty to 18 months and you will be included in it as well.
Best,
Khang

Re: SRT6 62mm Supercharger pulley??
call me stupid but how do you reduce the inner diameter and still get it to fit on the s/c snout? the oem or c3 is a extremely tight fit. no room for reduction there
and for the math guys, how fast would the s/c spin if this pulley is stacked with a 178mm crank?

Re: SRT6 62mm Supercharger pulley??
The inner diameter of the pulley is the outer diameter of the bearing (øD).
The inner diameter of the bearing (ød) is the same as the smaller diameter on the SC shaft. As long as the step clears the SC shaft (ØD) all is well with the world.

Re: SRT6 62mm Supercharger pulley??
it is interesting and if they had shown up before i went stacked i might have tried it. what worries me is they came out of nowere and havent ever posted on any forum i can find. just seems odd that someone goes to all this effort to build a pulley for a car no longer produced and a total run of engines less than 12,000. less than a couple months worth of engines from a ford plant
Re: SRT6 62mm Supercharger pulley??
This also something I'm interested in. I'm affraid that maybe the boost preasure would be to much at higher speeds. I will port my s/c by 2-3 mm to allow an increased flow of around 150cfm. Maybe the preasure will drop enough to allow for this mod.
Re: SRT6 62mm Supercharger pulley??
i called and asked rudy and didnt understand it then either . i guess i needed pics or someone to explain it in canadian cause english wasnt getting it!!

Re: SRT6 62mm Supercharger pulley??
178÷62=2.87
At an engine speed of 6,000rpm the SC would spin at 17,220rpm.
This has all been done before in earlier threads.

Re: SRT6 62mm Supercharger pulley??
i made an offer and was counteroffered at 750$. im not really a fan of someone who tries to sell their product by degrading another product. him telling me its not a c3 pulley which is a oem pulley with smaller grooves is incorrect. i run the c3 with zero issues and it has always been a quality product. so for now ill pass and wait till someone else does the testing for a change. 20 psi boost should keep me busy for a while

Re: SRT6 62mm Supercharger pulley??
The two former pulleys have had some problems, maybe down the road these new pulleys will be the ones to get, who knows.
The secret to a good pulley is the spring, the design and material of which is crucial. The dimensions of the pulley should mimic the OEM one and should fit with no changes to the shims, maybe a few thou ±, no more.
I think I will make one for myself, after all how hard can it be? LOL
Re: SRT6 62mm Supercharger pulley??
Surely something like that could be said for the C3 and EC pulleys.

Re: SRT6 62mm Supercharger pulley??
I was under the impression that when Code3 was doing initial testing, one of the main reasons they didn't go smaller was that there wasn't enough surface area for sufficient belt contact, thus causing too much belt slip.
I previously had one of the 2nd generation Code3's and I did notice I got a bit of belt slip at high boost/RPM's. Thus the reason why they engineered the belt wrap Kit.....??
Feel free to correct me if I'm wrong.

I also got the $750.00 offer.
