Drivetrain Twincharged MCS
>>OK two question on twin charged motors. First the twin charged motor that feeds into the intercooler is the air still going through an air flow sensor. Dumb question but I cant see the set up in my mind unless it goes air cleaner- sensor- then a split one path SC other path turbo. Next question on both twin charged cars could you use a SC pulley that is like an AC pulley? Clutch style so that when turbo spools up a boost switch could release clutch and let the SC freewheel. And I know the water pump issue so a elec. water pump would be used. I think I have seen a clutch pulley on a blitz add.
The MINI engines do not have a MAF. They use speed-density so there is no airflow sensor.
Mercedes uses a clutched pulley for the supercharger but I haven't seen anything like that in the MINI world.

What is speed-density? And is it still a sensor that gets a reading of the speed-denstity? If the pulley clutch could work would it not free up some hp? Seems like I read somewhere that the SC uses 60 hp at full boost.

Speed density uses a TMAP sensor to measure air temperature and pressure in the manifold, a crank sensor to measure RPM, and a lookup chart of volumetric efficiency values stored in the flash ROM of the ECU.
How would a clutch free up hp if the clutch needs to be engaged to turn the supercharger to create power? The Mercedes system disengages the clutch for the supercharger to slightly improve off-boost fuel economy.

Doesn't this just seem a bit much? I mean it's a $24K car (with options) and $5000 for these turbos.. Why didn't you buy a 350Z? Or perhaps that Neon SRT for a hell of a lot less and Oh.. A warranty. Does anyone else think this is just a bit overkill? I mean you know your car is not going to handle 250hp for more than 10K-20K miles.

For those of us with "the need for speed", no car in stock form would be sufficient. If I bought a 350z or nEoN, it would still get a work over of speed parts. Most of us here could afford either, or much more, but the MINI gives us something other cars lack--------->uniqueness. The guy who rolls up on you in his ______ would never suspect that a MINI was about to wipe his ****!

Isn't there a way to beef up the tranny so that you can get a reliable, long-running experience?
I'm not necessarily talking about this twin-charged Mini, but more along the lines of something like Mini Mania's Stage Three Kit with a Quaiffe LSD. $5,000-ish for 245 hp is a pretty good deal if it won't destroy the life of the drivetrain.

Not too many truckers in this crowd I guess eh? I am new to this site and just found this thread..
The turbocharger feeding into a supercharger is called "Jimmy" and Diesels have been doing it for.. gawd.. better than 20 or 30 years I guess. Trick is.. Diesels are REAL low RPM motors.
I am now going to look into this as an option... tres cool!

Look up Jimmy & Diesel in Google and you will learn an interesting phenomenon with a "Jimmy" if the drive system (blower belt in the Mini) breaks. I have seen it happen....
I was a heavy duty mechanics apprentice and the blower input drive shaft broke on a cummins "Jimmy" The system was twin turbos feeding twin 671 blowers.... when the blower shaft breaks the air from the incoming trubos spins up the blowers, which spin up the engine, which feeds more exhaust to the turbos, which spins up the turbos, that spin up the blowers, then... you see the circle formed? It ended with both blowers in the engine, in pieces.
I have spent a long time reading this thread, and I would like to do this modification. BUT, I would install a drop flap on the intake that chokes off the air... the devlopers have likely thought of this though.

>>I will shoot it when the car gets back from the west coast...should be back soon, I think its in route back to NJ...
Thanks Ace. Guys over the pond (especially me) are very interested in this. If possible in car and out of cars shots please. Thanks very much. :smile:

I am sorry I didn't get any video yet, but I am out of school now, and not in NJ anymore. I should be going down there this Tuesday though. I will call Hubie and see if I can shoot some footage. I will keep you informed...

the car has been to several shows. Hubie is about to release the kit; I've been working with him on a few bits and pieces. A teaser: you will get the Apex'i and specially fitted larger injectors, Ball-bearing Garret turbo with integral wastegate and custom lingage, larger intercooler, custom exhaust manifold and 3" downpipe, blow-off valve and probably a modified bypass valve. Hubie is a turbo-maniac and spares no prisoners!
