Might think about the DDM R50 CAI system, http://www.autoxcooper.com/ddm_justacooper.html plus you don't need to move the battery.

I have a CF "S" hood on my R50 that sucks in a ton of air, so not sure what temp my K&N is sucking, I bet it's less then 140 at speed.

Wow, I can not wait till you fly out to the land down under to tune some Minis. I had to take advantage of this awesome opportunity. When do you think your cam and header system will be out? I have been thinking of those two things for my R50.

Only in your small little world you live in. Heck I've even had a change of plans. Precious will be returning to stock form in 09' (as the SCCA see's it) and she will still beat your NGGT. All my mods will go on Gina's Mini (when we get it) and I will run HS for all of 2009 while my stroker 2.0 turbo project gets underway. If you were wondering Dee I'm not using the MC motor, tranny or transaxle I will be buying from a salvaged S that has no front end damage or that has been rolled. Jan when the time comes in LATE 09' I would like to bother you with a full custom ECU mapping (I'm told it's a very involved process and it's understood in the industry your the best).

We just haven't found a place to race yet, but I am anxious to do so. Timing is everything...

So I presume the 109.2 hp was before the tune and the 116.4 was after the tune? If so 7.2 hp from a tune is pretty darn good.

Just out of curiosity, how much extra hp do you think a header and cam will add? And if the car was tuned with those on it I presume the gain from the tune would be greater than just from the CAI and exhaust, yes?

having talked to guys that know heads better then I do, I'm told a head and cam would add 15-20 bolted on and tuned maybe 10 more. There have not been any reports of anyone doing it. I know Jan is working on a Just-a-Cooper at this time and will be reporting soon. My plan is to drive the setup I have now till she blows, then rebuild the motor as big as my budget will allow at that time, get a tune and myself.

Im not too sure about a new head, but im interested in doing headers and cam as soon as possible. My goal is to get these two things done so that I don't have to get it retuned later. Its not easy getting a custom mini tune here lol.

Speaking of all these headers, which is the best bang for your buck?

The cheapest you'll find is Ebay headers. But, you're also going to get Ebay quality. This is one example where you could buy 3 Ebay headers for the price of 1 Jan header. But, Jan's stuff is made to specs, looks better, has been scienced out and is a sure bet for making power. Your choice.

another tank still got 34mpg and the other late night had some expressway to myself and without getting into the details, let's just say 4000rpm to 6000rpm at speed is SICK!

Exactly what did Jan do to you MINI? Did he change the programming in the ECU?

The Tune is $350 but you also need to budget Dyno time. Based on NAM postings you will need to budget $100 or more for dyno time.

Assuming my cat pipe build and header install go well next week I'll be sniffing around for an opportunity to get in on a Jan tune. I'll finally have checked off everything on my JustaCooper drivetrain pre-tune list: intake, throttle body, cylinder head, cam, header, catback.

None of this stuff is from RMW as there wasn't any RMW stuff available, but I've chosen the bits and pieces carefully and I'm looking forward to seeing how it all works out. I admit the TB may have been a waste (maybe...), but the rest of my choices seemed right (to me) to work together as a system on an R50.

Hmmm, I wonder how I go about trying to start a "Jan tune in (or near) DC" campaign.....
