Unless you have a modified cylinder head with larger valve (larger outlet, maybe larger inlet) I wouldn't go further than 15% due to reliability during high speed driving or track days.

If you're using your mini just to get the shopping bags home without going into high revs 17% might be O.K.

Just my opinion.

Go for larger intercooler, GRS or GTT and you could also do enlarged crankpully to make the JCW effectively like a 15% pully

17% might be ok? I have a bone stock head. I have a 17% and my car lives a lot of its life above 4000. Seems ok to me

And anyway, many people run 19% pullies on stock heads without any problems. Go with whichever pully you feel comfortable with

The thing is that i dont know exactly the differences. I use the car as everyday car to go to work, i dont do track days neither drag races. Just i hit it a little bit hard in the motorway and this is just for 1-2 minutes. Nothing more. What pulley to use with this style? 15%? I aiming for about 200 - 210bhp

Whatever pulley you go for make sure that you have a good map (re-map) to go with it as it will protect the engine. Also as Cyprus is very hot (i'm kinda here

) then you will definatelly benefit from an uprated intercooler, especially if you are planning to have a pulley done at a later stage.

Thanks Lohen. I was thinking of an interooler and the water spray system for that reason as you said temperatures here are going crazy. Today as an example is 38 - 40 degrees. Thank god my DS bullet is garaged hehehe. . So you have being to Cyprus then?

KMK163 · Jun 20th, 2006, 07:03 AM

I have found a second hand intercooler that was on a cooper s automatic transmission though. Does it has any difference from installing it on a manual one?

Lohen · Jun 21st, 2006, 11:20 AM

No there aren't any differences as they are all the same in that area, we are kind of out here at the moment.

One more question to Andrey. And to anyone aelse that have a clue, I have also started a topic, does JCW manifold has any differences with stock MCS manifold?
