Hi,

I am considering having the 225 upgrade done on my 210 JCW.
I am aware you get the motorsport manifold with this plus a New supercharger with a reduced pulley.

Please can any body tell me which version of the Eaton 45 supercharger this is and the % reduction of pulley .

Wouldn't adding an exhaust header and oversize crank pulley offer the same result and cost less?

also the jcw 225 kit is no longer anvailbe as JCW motorsport ceased to exist last year far better off going to see Roland @ GTT imo its where i would go

if you have the 210 kit then already have the new charger as the old jcw charger became the same as the stock one from 07/04 onwards the only differnace between old and new is a teflon coating in the charger that part is only shown in the jcw upgarde as it would be fitted to a pre a 07/04 car

163bhp MINI's have an Eaton 3
The Original 200bhp JCW Replacement Supercharger was an Eaton 4 (with Coated fins and smaller Pulley)
170bhp MINI's have an Eaton 5 Supercharger (Coated fins and other improvements).
The Newer 210bhp JCW Replacement Supercharger is an Eaton (same as the 170bhp just a smaller Pulley).
The 200 to 210 upgrade doesn't include any changes to the supercharger.
The 225bhp JCM Supercharger should be at least an Eaton 5, however its polished/ported aswell. Not sure if the pulley size is the same as the 210 and 200 ones though.

But as MINAC and JWF said there are cheaper ways.

so if you have an eaton 3 charger and can pick up an eaton 5 for cheap money, is it worth doing at the same time as you do a pulley change???

i assume the teflon baldes are for strength etc, and assume some flow changes too

An Eaton 5 is always going to be better than a 4 or 3, however not sure the cost involved in changing a supercharger vs just a pulley change.

from what i have seen chainging the charger is a meduim ish job as most of the front of the car has to be removed were as changing the pulley is a far small job AFAIK

What is your source saying that a 3rd generation Eaton was used on the MCS?

Eaton’s first generation supercharger debuted in 1989 on the Ford Thunderbird Super Coupe. Over the next decade, Eaton continued with design, performance and noise, vibration and harshness (NVH) improvements in its second and third generation applications. The Ford Lighting SVT and MINI Cooper S used Eaton’s fourth-generation supercharger and introduced a patented island bearing plate port configuration, which improved noise and vibration characteristics.

In 2001, Eaton’s fifth-generation supercharger was made even better with the introduction of a patented abradable powder coating to increase volumetric efficiency, and a patented integral shaft bearing, which provided a packaging and cost improvement.

Not sure the 3 4 5 realtes to the generations, maybe just the variant or version for the MINI. But defo read somewhere the numbers 3 4 and 5 relating to MINI.

Either way ther Supercharger on 163bhp is not the same as the JCW 200bhp version.
And the 170bhp Supercharger and the 210bhp JCW are the same but different again to the 200bhp JCW.

The 4th generation Eaton M45 was used in MCS models built prior to July 2004. The 5th generation Eaton M45 was used in MCS models built July 2004 onward and in ALL Works Kits. The difference in horsepower between the 200bhp and 210bhp Works Kits is attributable to larger injectors plus associated ECU remap and an intake.
