I'm in the market of buying a MINI JCW
CLUBMAN very very soon. However I was just wondering whether or not I could fit a dump valve on it ? and will it void my warranty? also are there any performance enchancements?
I've never driven new turbos like the RS56/55 where i virtually felt no turbo lag at all. Now the turbo vehicles that i used to drive (early 2000s and late 90s) had turbo lag and the dump valve helped performance.
I'm just trying to figure out whether or not the JCW
performance can be improved even further, not saying that it isnt a great car and a really fun car to drive (i've only had roughly 30mins on a RS56), but i'm just wondering whether or not there is still room for improvement that won't cost the world.
