Hi :smile:
I have some questions about the "connection" between the Supercharger and the throttle body on the Cooper S.
I`m building an custom setup flat-4 vw motor, and i`m going to use an Supercharger out of an Cooper S. I was also thinking of using the original throttle body from the Cooper.
But - is the throttlebody bolted directly on to the supercharger, or is there any kind of connection between them?
Any pictures out there?

My blower is made in september 2004, so i guess it is an Gen4 or 5, does anyone know?

 

the big black square is the charger the small square is the TB they are connected by a tube

 

The MINI supercharger is connected to the throttlebody by a long somewhat flattened tube. M7tuning has produced their Air Gain system that effectively replaces that long tube with a shorter one providing a less restricted air flow path from air filter through throttlebody and on to the SC.

Here is a picture of the M7 AGS and note the short black tube in the middle-
Blue air filter to the right is attached directly to the TB.
Picture is from the M7tuning how to guide.

 

In theory ... and contrary to testing results.

 

Were there test done on flow? Or just HP numbers?

 

Just HP numbers. As far as I know, nobody has done flow testing on the entire system (including the people claiming it outflows everything on the market).

 

So your statement that their theory of a " less restricted air flow path" was "contrary to testing results." is false?

 

<sound of crickets chirping>

 

Yep, it's only been proven that the AGS makes less power than the Alta. It hasn't yet been proven that it flows worse, although it probably does. How's that?

Do you have access to any information that supports the "outflows everything on the market by a margin" statements that were spouted by M7?

 

<sound of crickets chirping>

 

Why would i? I drive an MC and have no affiliation with M7, or any tuner company for that matter. I was just pointing out that you were making another false claim despite your "activism" against false claims. Sorta silly to jump on someone for something that you are guilty of doing as well

*edit* apparently NAM has come down with a cricket problem....who knows the number for the local Orkin man?

 

You may not have affiliation with M7 but a simple search of your posts reveals dozens if not hundreds of instances of you speaking on the behalf of, and defending M7. Do you believe that M7's claim that their intake "outflows everything on the market by a margin" is true until proven otherwise?

In fairness, I should have said:

In theory ... with no supporting evidence for the flow rates, and contrary to dyno tests that show it losing power compared to the Alta. How's that? :smile:

 

Actually, a more correct point would be "contrary to dyno tests that show it making less power than the Alta". Because "in theory", its not losing power, although it makes less power than the alta, it still MAKES power, not LOSES. Hehe, btw I just thought I'd bite since your being a smart-a**. Now, although RallyMINI might defend m7 products that doesn't mean he is in affiliation with m7. I'm sure you defend products you like as well, theres no harm in that. And it's kinda sad how you chose to deviate from the topic just to input how the m7 AGS doesn't perform as well as the Alta and how there are no flow rates posted by m7 yet they claim it to to flow better. The original poster never asked for your opinion about the m7 AGS.

I'm not going to answer the question as it was already answered by minihune and profpatpending.

 

I was simply clarifying/correcting minihune's post, which kindly answered the original question.

 

You will not find me speaking "on behalf of M7" ever. I helped people find public info about M7 maybe, but never "spoke on behalf of " the company. Secondly, while you are searching all of my posts, you will find that i stick up for ALL vendors/tuners. I think people bashing our vendors is pointless.

I have no feelings towards the AGS at this point, no care whatsoever. They can test it, or they can stick to just selling it. Either way, i wont buy one because i dont even have an MCS.

You could say, But what would the power gains have to do with this thread? It would seem that you were only saying that to get in another bash on a vendor. Not much better than the original false claim.

The fact is, you made a false claim and yet you try to accuse other people of the same crime.

 

You neither clarified nor corrected minihune. You just stated that it hadnt been tested. And then went off on a tangent about horsepower....(minihune only talked about flow)

 

You win. Interpret my posts however you/M7 would like.

 

Back on topic, don't forget that the throttle body is drive by wire (no cable connected to the pedal) so that's an obstacle you'd need to overcome. Also, this guy is selling the connecting tube:

Frankly, I wouldn't use the MCS supercharger for a flat-4 VW. The mating surfaces are too weird and you'll have the useless water pump drive spinning on the backside of the supercharger (you could just cover or ignore it, I suppose). A centrifugal supercharger like a Vortech would be much easier to package and plumb.

 

Thanks for the pictures - that was all i needed

There is, i suppose, better SC`s to use on an flat-4 VW, but i got this so cheap, so i just HAVE to use it. This want be a street driven car, so i dont need the cooling (i have lots of space).
As for the water pump drive, i guess it dont have to be covered either, as this will be a 1/4mile car only.
Maybe i will make a custom tube between the SC and another throttle body, thats why i needed to see how the original looks like.

Some more questions: Is it possible to use this supercharger as a draw through with a carburettor? (Fuel and air will go through the SC).
And how many PSI will this unit hold? I remember to have read that the original on the MCS is 6 PSI, but this is very little. I thought of something between 15 and 20 PSÌ.

 

hmmm...flat 4 huh? did it come out of a 'type III'?? (VW) i have a type III fast back (67') big fan of Vw's myself!!

sounds like a helluva project! would be really interested to see how it turns out.

 

Popcorn!

Hot Dogs!

Fresh Roasted Peanuts!

 

Flat4 yes
I will use a Type 4 engine, 2 litre with lots of mods.
And it will be in the back of my Fastback, i have an 66'.

 

Ooh, fastbacks are sweet (almost as sweet as notchbacks). :smile:

Good luck with the project.

 

a bugaboo with the Mini setup is the punky, almost laughable, "mechanical" connection where the SC seals to the intake tube. I'd fix that issue.

 

wow man a 2liter in ur type III thats some serious power!!
what crank & rods?? i have a skat crank w/Carillo rods looking into a type IV w/Porsche shroud & alt. (soon enough...) i assume ur runnin' 48 IDA's or larger??
