I’m sorry to hijack the thread. But let me ask the OP since he is in the engineering side: would you be interested in manufacturing an adapter tube for me so a manual transmission SC would fit my automatic MCSa? |

Hope all is going well. On the upside a friend of mine was kind enough to lent me his r56 MINI for a full engine 3d Scan !!! I already did some small designs but that's for later ! |

But let me ask the OP since he is in the engineering side: would you be interested in manufacturing an adapter tube for me so a manual transmission SC would fit my automatic MCSa? I could order the original charge pipe from BMW, 3d scanned it and have many reference points but I would not be happy without a full engine scan plus an actual car with automatic gearbox. So yes I want ! but... how ? :confused: |
I could buy it and have it sent to you. I can buy the pipe. But ai cant secure a Sprintex SC for you. |
Sprintex ?? I thought it was an OEM unit. Sending to me the OEM charge pipe it not going to change something, I can buy it from the local dealer, that's not my problem. The actual car is ! I need to measure something :lol: in order to proceed. Do you have anyone with a 3d scanner around your location? The problem is that I have to available my designs and test fit every small detail in order to be sure.
|
Forgot to mention: so far I drive my car in a daily basis for 4.000 km + . And around 2.000 km with the printed heat shield ! . I use it everyday, in heavy traffic, high way and some spirit driving in a local mountain.
|
Sorry man. No 3D scanner in my area at all! |
Cool I know you had the fires around you and everything. Wanted to make sure you were good.

I like your pipe idea more than the air filter idea. The filter up by the cowl I think provides better (cooler, more) air movement. Question, do you have an idea if the pipes will be printed plastic, carbon fiber, or... The reason I ask goes back to my original comment about a rotating/spinning air stream. If it were printed, it would be easy to install a divider or vanes to keep any air swirl down. A carbon fiber tube would be more difficult to do. My reasoning for commenting on this, is I've been porting cylinder heads for a long time. I know how easy it is for air (or even air/gas) to start swirling/rotating in a port. When air starts rotating, the center gets hollow, as in...no air flow. One BIG reason intake ports are...not round in performance engines. The big "Tunnel Port" Ford heads were pretty much a failure because of the round ports. I'd defiantly be interested in buying your charge pipe if it had some way to keep any rotating air movement to a bare minimum. Mike |

I'd defiantly be interested in buying your charge pipe if it had some way to keep any rotating air movement to a bare minimum. Mike Design is not my problem. The problem is the manufacturing. The way it is designed my charge pipe keeps pressure drop and vorticity to a minimum (Minimum for this application) . The only limitation is the available space. In another engine bay, with space etc etc you could have different results. My main thinking when I started designing the charge pipe was the plug and play fitment without any cut or modification. I haven't done any dyno yet, but so far I have seen an increase in the boost pressure throughout the RPM range in all the gears (peek and average values, so yes it performs better). Yesterday I saw 16 psi at the rev limit in all gears , it was a first (always comparing with the OEM setup, same temperature) and especially with 26 degrees outside temperature. I posted some graphs from some data logging I did the previous month. For sure it performs better than the OEM unit I can see that every day, I loved it, the problem is that I have to dyno it first to back up my words! But with 30 degrees outside temperature around 11 am I dont feel like taking my daily-project car to a dyno session. That's why I would wait a bit more for the weather to cool down and see some back to back numbers ! |
I'd say, getem made.
A straight, or "even cross section" tube is MUCH preferable to the convoluted/squeezed tube from the factory. If this truly does fit a stock R53, sign me up now, I'll make up my own anti-swirl parts. I can be a test subject..! Mike |
Some great work there! I too would like to see the air filter up in the cowl makes more sense to me.. I'm very interested in your results, how far away from production are you?

6000 km of testing and everything looks good ! I am so happy with the charge pipe ! I remove everything again just to inspect everything.
I also had my B14 Bilstein ( all 4 of them) completely refurbish as one shock was making a terrible knocking noise the last 5 days ! Currently I am also working on a Ducati and an R56, trying to make some nice stuff :) I could share with you guys if you would like to see more stuff! :popcorn: https://cimg1.ibsrv.net/gimg/www.nor...1b556a57aa.jpg Carbon Fiber Charge Pipe ! |
That looks great, ready to bolt one up to my car.
|
I forgot to say that I also ordered more fuses and cables from BMW in order to make the TH extensions kits. I will update with that as soon as I start with them :lol:

I'm still in for one.
One observation, the throttle body flange seems very thin. I'd say double the thickness, like you did the standoff pipe below the flange. Since the throttle body isn't really a light weight, it's safer than to be sorry, I'd think. Shoot us a price and delivery schedule..! Mike |

Printed model of the JIG. I used PLA as material, something cheap for now in order to do a pre-check in the upcoming 4 charge pipes. More or less I consider all of them prototypes as I want them to be used in cars that I know the owners in order to have feedback. Next JIG will be printed out of NYLON 6, which is usually the material printed jigs are made with some design improvements.

And some small details that I was working on previous week.
Left photo: Mock-up bracket. Still playing with the idea of making it from carbon fiber as well. Not sure yet! But at least the bracket, design wise and fitment, it's done. Right photo: I added a spacer to the bumper, I used an OEM spacer (all our MINIs have these spacers) just to give a bit more clearance. So far I had no touching but I prefer to be on the safe side. https://cimg3.ibsrv.net/gimg/www.nor...76b818413b.jpg |

Definitely want to follow this.
As was briefly mentioned, getting cooler air from the outside engine bay would be advantageous. |

Thank you guys for your nice words!
Yesterday I went for a drive up in the mountain with a friend of mine and I made a small video. Nothing crazy just playing around with video editing :lol: and smooth 4 (phone-camera stabilizer ?? ) I just got :lol: The red r56 you see in the video is my friend's car, a very nice and tidy r56 :cool:. He was kind enough to lend me the car for a full engine 3d scan !! I have some nice ideas which I would like to play around later in the future !! But for now the charge pipe should be finished :) |
