A seller on eBay has a "Mina lower supercharger pully" for sale, although I didn't know that Mina ever sold them. Did they? The "Mina" pulley on eBay is anodized black.

Powerhouse UK sells a lower pulley new, and theirs looks identical but is just raw aluminum or clear anodized silver.

Anyone know if perhaps the black "Mina" pulley was just a black anodized rebadged Powerhouse unit, or...

Curious if they are the same size, any different, or any other similarities or differences to be aware of.

I bought ( but have not yet installed) the Powerhouse unit. It's very nicely machined, and also came with a new belt and instructions. I've never heard of Mina.

 

Any chance you can measure the diameter of the Powerhouse UK pulley?

Regarding Mina, they are a Jaguar aftermarket vendor:

Jaguar Performance Parts and Accessories


I've dropped a note to Mina to see if they do sell an XJR6 lower pulley, although it isn't listed on their website, or if they perhaps sold one in the past.

Eurotoys did, or currently still does also sell an XJR6 lower pulley, and their documentation says it is anodized black. So maybe it is a Eurotoy:

Total diameter is 8 1/4". Diameter across the top of the grooves for the belt is 8 1/8".

 

Thanks, they also confirmed 205mm


Any idea what the stock pulley diameter is?

.

 

7 1/2" total diameter, 7 3/8" across the belt grooves. The Powerhouse one is 10% larger, as advertised.

 

Thanks, can you post the new correct length or make & model number of the belt that was provided and is now required for the larger lower supercharger pulley?

That will be a good reference for anyone else using that pulley in the future.

I don't know the length, but the belt is a Goodyear 7PK1220.

 

"the belt is a Goodyear 7PK1220"


So the effective length is 1220 mm

 

I had no idea that was how the numbering system worked!

 

Jagbio64,
As far as belt designation goes, you have probably realised the 7 means 7 ribs, but may not know that PK defines the pitch and angle of the ribs. The alternative is PL.

 

Did the kit include torque values for the four pulley mounting bolts?

I also asked that question here:

I'm trying to get all the information together to mount mine.

 

No, just "torque to Jaguar specification"
