Thanks ab

Did anyone have an answer to this question?

Also some people seeem have to have the question about the popping disappearing when the JCW CAI is installed and that is untrue. I still have that popping. Now I have two sounds I love, the popping and the high whine at high recs. NICE. Recommend it to anyone with a Mini.

besides the price / and airbox repacement what it the difference between the 2 products? pros/ cons

performance?

Yes, it’s under the intercooler. NO! Don’t remove the intercooler! If you already have go ahead and install a larger one while your at it you should get some benifit from all that work. LOL;)

But seriously, you will find this vacuum line near a round valve just to the right of center as you face the car. It will appear to be impossible but I have large hands and long fingers so it is possible to connect the lines. I’ve done two. First remove the hose from the valve that you find under the intercooler. If it will not pull off easily, pinch it between your index and second finger like a cigarette and push it on. This might sound crazy but it breaks the seal and allows the hose to be pulled off. Once the hose is free push the end of the new JCW (Y- connnector) into the hose under the intercooler. Taking the hose free of the intake helps a ton. Again I used my index and second fingers (on both hoses) because my thumbs wouldn’t fit. Now with the JCW hose connected gently pull the hose toward the valve and it should go on easy. Reconnect at the intake and rev to 4500 and listen to the music.

After reading the well written review I decided to buy and install myself even though I know better with my VERY limited mechanical skills. It’s been fairly smooth (thanks for the white and red and not red and white tip)except for the vacuum line. I have been unable to locate the vacuum unit. Is it underneath the intercooler about halfway down the length of the intercooler? If this is the right location how do I get my hand in there? Do I need to remove the intercooler? Any assitance will be appreciated.

Thanks,

BMW pretty much pioneered the sport button altering throttle curve and steering weight, changing the aural characteristics is bound to be next.

The last 911 i drove (an ‘05) had the sport exhaust – a dash switch allowed the bypass valve to open at low rpm for more rumble.

Last weekend i followed an R32 through the hills and flagged him down to ask about the exhaust – it looked stock but sounded even nicer. he had rigged the flapper valve open and other R32 owners install a dash switch to force it open at all rpm or have it open only at high rpm.

The RS4 does the same thing when the sport button is pressed.

(Not that this tech is that uncommon in exhaust systems: 3000GT, Acura RL, E36 328i for example).

so to make a long story short, BMW insiders if you’re reading this please give us more cockpit adjustability for such things in the future – sometimes you feel like a nut, sometimes you don’t. i’d tolerate iDrive if it let me get in and set up the car the way i wanted.

sorry to veer off topic – having driven the JCW kit with and without the new intake I love the way the intake helps the mtor pull cleanly into the limiter. The MCS and oriinal JCW always felt a bit congested to me.

p.s. Mike Tiger – read up on the JCW kit for the NA Cooper. To get that kind of gain JCW had to rework the head, ECU and exhaust as well. : – /
