Hey everybody!!
I have a JCW car which has a (~) 11% reduction pulley (i.e. a standard JCW pulley which is 11% smaller cf stock S pulley size). My car was build prefacelift in 04 so will have the non-teflon coated Supercharger. When my car got the JCW upgrade it was the 200 version (i later added the kit to bring it to 210), so I assume it wont have been given the teflon coaten SC that later works cars are given? or did all JCW kits get the latest generation SC and the only difference between them (the 200 and 210 kit) is the air filter/injectors?
I was thinking of getting the JCM 225 kit but it has a 19% pulley which I dont like so was thinking of getting a custom JCM 225 kit - i.e. it has the mani cat and upgraded supercharger but with a 15% pulley....
...but I wanted to know what the actual gains are likely to be.... the difference in standard s (with the different SC - pre/post facelift) went from 163 to 170 some of this due to ecu changes im sure but the rest down to the SC (?) so if we assume about 5bhp for the SC (if i dont already have the gen5 SC???) what sort of increase are we likely to get from the 15% pulley???
In short:
1. What gen SC will I have - is there a way to tell from looking at it (without looking at the internals)?
2. What are the likely BHP gains from going from 11% pulley to a 15% pulley?
3. What are the likely torque gains from going from 11% pulley to a 15% pulley?
4. Does any of this make sense or am I typing too quickly cos im at work??? :) :) :) :blink:
Help/advice is appreciated.
