I found that my K&N was drawing in 140deg air!! So I put the stock air box back with a hi-flo air filter and saw a noticable improvement in power and gas millage. I will be going with a CDA filter and cowl-indution CAI once the battery is relocated to further drop the air intake temps.
BTW I had Mini-Madness due a tune to my R50 with the same results! An ECU Ttune for the R50 is a must!!

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.

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).

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.

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.

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.....
