[quote]Finally pictures and specifics...

M7 Speed Inc. is proud to announce the newest development in a line of innovative products to be released over the next few months.

The Autorotor Supercharger from Sweden will soon be available for the Mini, exclusively through M7 Speed and Mini Mania. This twin screw SC feaures fantastic specs. With capacity to put out 21 psi of boost with a 57mm pulley, this SC will easily generate 300+ hp.

The system we designed has a new intake manifold with a built-in air to water intercooler system, which significantly lowers the already low charge air even more.

The cooling sytem is another M7 innovation--which utilizes parts of the car to cool down the coolant (water) without the need for extraneous water reservoirs in the trunk or under the car.

As the new SC does not have a waterpump attached, we are utilizing an
electric water pump with a control unit that will sense the temp and adjust
the flow accordingly.

All fastening hardware in the kit are grade 10 or better and the CNC machined brackets are anodized 6061 aluminum. Replacement hoses
are silicone with stainless or anodized fittings.

To compensate for the higher fuel consumption, larger 520cc injectors
have been added to the kit. To control the fuel mapping, M7 is using
a piggyback fuel enrichment computer.

The unit will be C.A.R.B certified and as such will also be available for California Mini Cooper owners.

Price: approx $ 5600.00
Warranty: 1 year
Availability: approx. 4 week lead

Look for more innovative products coming soon from M7 Speed.


Here are the pictures

Waho, finally some serious stuff from M7. Nice to see!

 

found some more articles on it comparing the roots (the same make as the S?) to twin rotor (M7) as tested on a 'stang I think




I REALLY WANT ONE!!!
just imagine with the DEI Cry02, Venom Nitrous kit, CF everything.........

Bet that monster voids the warrenty

 

two questions

1)peter when will this be available

2)can it hang wtih a stock bottom end, or willl the bottom end need to be strengthened?

 

I have seen a similar unit used on a vw cabriolet. From what I have heard it makes great power. If I had the funds I would look into becuase I like the low down power of a supercharger over a turbo.

Keep the products coming.

 

>>So, I am confused, is it a replacement for the Cooper S supercharger or a supercharger for the standard Cooper? (Or both?)

replacement for the S supercharger I think, (doesn't look like theres plumbing in the pic for the cooper) I might be wrong

 

It's for the S only I believe.

You can learn more about it, along with other M7 products, over on my boards, where it's mentioned 1st and Peter will be trying to tend to M7 Q&A ... but he is a very busy person...so obviously he won't be able to answer all the questions at once.

I can tell you though, there will be more announcements in the next week and following.

 

Sounds very promising, except for the piggyback computer. The stock ECU surely can control the new injectors, it just needs the proper programing.

 

Interesting thought.....

 

After chatting with Peter a few times, I know that he likes to not beta test on customers, so I'm guessing that this has already shown some degree of promise!!!

Great news indeed.

I guess if the gearbox can take the gut-wrenching power nitrous delivers (at least thus far), this should fine. Right?

Hi Guy's

The supercharger package is for the MCS only. I do have some sweet morsels for you MC owners by next week.
The unit can be bought with differerent size pulleys to allow changes in boost pressure, these pulleys come of realy easy
basic tools will do it and the cost will be less then $100. I do not forsee a problem with the stock bottom end unless you go crazy with the boost.

OK, this looks powerful.
Here are some obvious questions for an FAQ.

Seem it is only for the Cooper S? Seems to be since it replaces the stock SC. Not for the MC since there is no SC.
Warranty : 12 months
Availability : 1 month
Cost: $5600

Driveability- Ok for street use?
Torque range and amount" 300+ HP
Top speed any more?
Redline- higher?
Performance- 0-60 difference or quartermile times, difference of lap times on track?
Noise levels- much different?
Gas Mileage- much worse?
Fuel requirements- 91 octane
Effects of overall engine reliability over time? Does this wear out the engine prematurely?
Different engine oil requirements or more frequent oil change intervals needed?
Any other unknown(known concerns with unknown outcomes) ramifications of this upgrade?

What other systems are stretched to their limits of design. Cooling, structural mounts, transmission, intake, ECU, exhaust flow, ignition, etc.

In order to balance power with the suspension- what level of suspension and brake tuning is needed/recommended. Surely it would be a bad idea to just add this type of power without addressing other supporting systems. 300 HP and stock suspension and wheels might be a recipe to something other than fun. (Danger).

 

I can't wait to see it installed. I want to see how it perfoms SO badly...

 

minihune, i dont know much about cars, but will try to help out a bit on the FAQ


>>Driveability- Ok for street use?


henessey makes power upgrades kit for dodge vipers. the stock viper has 500HP, and the henessey kits make them about 800-1000 HP...are they daily driveable? well i think the question is relative. is 500 hp viper daily driveable? some would say yes and some would say no. i think with this supercharger you can certainly use the mcs for every day use, then again a mc is fine for everyday use, so i think its all relative.




>>Performance- 0-60 difference or quartermile times, difference of lap times on track?


being in drag racing for many years, that time you get at LACR in palmdale will vary GREATLY from the time i get at california speedway. so i think after a few customers get this on thier car, at that time #s will be be available. he said there is a 4week leadtime on the product. i dont think he is out on the tracks (infinion raceyway) trying to get the track times for the mini yet





>>Gas Mileage- much worse?



if u gotta ask, its not for ya 300 HP..forget about efficiency..



>>Effects of overall engine reliability over time? Does this wear out the engine prematurely?
?




as with all motors, when there is extra pressure, there is chance of degradation of the engine reliablitly. my stock crx came with 110 HP. after turbo'ing i was putting down 227 HP at the wheels. i drove that car for 2 years with 0 problems, and put in about 36K miles on it. however i have seen people build honda's wtih 180Hp that blew the motor. it all depends on how you drive your car and such. as you know many people have probs with thier minis, ,but me and you dont have any, there lies the differences. whoo knows why. will people who got their pulleys from randy have premature engine failures? we wont know till they get higer in the mileage. so i believe you cant really ask this question fairly.

 

Arrr Maties! If you run an electric waterpump you're asking fer trouble.

Sounds very cool but I have some questions and concerns:

1. Spending the 5600 + 1k+ (install) on this seems ok but this is still only 3 pieces of the puzzle to gain all this boost and power. You still need to spend the cash on Head, intake, exhaust, Throttle body etc. I would imagine that you will not see all the gains unless you have these other pieces. What do you guys think?

2. Can the drivetrain handle it? Gearbox, clutch etc ??

3. It sounds like there is speculation about what it will really do. I guess this means no one has actually tested it on a Mini S yet? if so please post the data and pictures, how too's etc. I would not touch this until after 6+ months of proven testing but hey thats me.

4. Is that in the pic 4 throttle intake pieces? This would mean that you need 4 custom throttlebodies required for this conversion? That doesnt seem to be mantioned. I bet thats going to be expensive also about 5-600 per and the piggy back would have to control them cause the factory ecu wont. Does a 1.6L really need 4 throttlebodies?


5. Do we really need to change the Supercharger to get to 275-300hp or is there another way? Maybe just go to 2.0l with intake, ecu, head, header, exhaust, pulley etc.. I think that some cars out there are 240-250hp already with 1.6L and the factory supercharger. It looks like you could spend 10k really easy with this supercharger upgrade after its all said and done.


What do you guys think?

hi Coopertino



>>1. Spending the 5600 + 1k+ (install) on this seems ok but this is still only 3 pieces of the puzzle to gain all this boost and power. You still need to spend the cash on Head, intake, exhaust, Throttle body etc. I would imagine that you will not see all the gains unless you have these other pieces. What do you guys think?

The idea with a more efficient super charger is not to go to 300+hp and hope for the best. The Autorotor unit
is incredibly efficient allowing you to run lower boost with higher horse power rating more torqe and less strain on the intercooler and periferal equipment. If you add head, header, cam and throttle body you will gain more hp.


>>2. Can the drivetrain handle it? Gearbox, clutch etc ??

Again 300hp is pushing it but you can gear the unit down to 200-220-240-260 etc with our replacement pulleys
I have been pushing 250hp with huge torqe for a while now with no ill effects.



>>3. It sounds like there is speculation about what it will really do. I guess this means no one has actually tested it on a Mini S yet? if so please post the data and pictures, how too's etc. I would not touch this until after 6+ months of proven testing but hey thats me.

We are beta testing right now and putting 7000miles on the unit to make sure their is no teething problems.
All requests about data, how to's etc will surely be answered in time. This was only meant to wet you guy's
appetite more will come guaranteed. Also about speculation...there's no magic here this unit has been tested
on thousands of vehicles and it works. No units will be sold untill it's perfect.


>>4. Is that in the pic 4 throttle intake pieces? This would mean that you need 4 custom throttlebodies required for this conversion? That doesnt seem to be mantioned. I bet thats going to be expensive also about 5-600 per and the piggy back would have to control them cause the factory ecu wont. Does a 1.6L really need 4 throttlebodies?

The cool thing with our unit is we re-engineered the intake manifold with an integrated air to water intercooler
allowing a shorter air path to the engine. The throttle body looking things are the intake runners which are
venturi shaped for higher air velocity, we are still using a seperate throttle body, regular size for lower hp
or our oversized unit (61mm) now available at Mini Mania for $399.95 plus core


>>5. Do we really need to change the Supercharger to get to 275-300hp or is there another way? Maybe just go to 2.0l with intake, ecu, head, header, exhaust, pulley etc.. I think that some cars out there are 240-250 without this upgrade that looks like you could spend 10k really easy with this supercharger.

To push high 200 or in to the 300hp teritory forgett the stock unit(SC) specialy if you are concerned about reliability
charge air temps, water cavitation, bearing seals etc. The otherway with all your above mentioned pieces expect
a hi-reving hard to drive monster no fun at all. With a small supercharger like the M7 unit expect stock driveability
and a realy fat torqey low end that a twin screw unit can deliver.

The piggyback computer we are using is for the 520cc injectors which are necessary for the high hp needs
it will allow us to take advantage of the stock ECU parameters but in the same time add fuel mapping forhigh loads.

Also available now are our new 380cc injectors that fitts in the stock location.

I am not sure if this is true as most v8 guys who build their blocks always go with electrical pumps. And you I am happy to see someone taking Talk-Like-A-Pirate day seriously!

 

Peter,

If someone with an MCS was interested in planning to get this upgrade what mods can be done now that would NOT interfere with adding your product. Obviously doing any stock SC mod would be a waste.

Lets start with engine mods.
Any restrictions on the following:
Intake- should work with Alta and hose?
Throttlebody- you already mentioned 57 or 61mm avail.
ignition- work with pilo upgrade and plugs, colder plugs, MSD coil/wires?
Exhaust- work with header like London stainless, any high flow or backpressure problems with Cat back exhausts? Like some systems might be too restrictive- cause too much backpressure?
Intercooler- OK to use Alta larger intercooler?
Radiator- need a larger radiator?

Obviously you can add any suspension and wheels/brake system upgrades.
Thanks for the info and planning. Got to save up.

Also how many hours to install- labor estimate costs?

 

 

>>Lets start with engine mods.

Yes no problem at all, the stock location of the TB will be retained for now.............
.
>>Throttlebody- you already mentioned 57 or 61mm avail.
>>ignition- work with pilo upgrade and plugs, colder plugs, MSD coil/wires?

we are possibly adding the M7 Plasma Booster to the package and the Pilo uppgrade could be worthwhile......

>>Exhaust- work with header like London stainless, any high flow or backpressure problems with Cat back exhausts? Like some systems might be too restrictive- cause too much backpressure?

We have a new exhaust system comming at about the same time as the SC will be released, and of course you can use
anyones exhaust, we will do some testing with different header/cat systems.

>>Intercooler- OK to use Alta larger intercooler?

You will not need one as the system integrates an air to water intercooler system that is much more efficient then
your traditional intercooler and takes a smaler space. This will allow for more efficient packaging less hood height
required.....Which allows us to............ :smile:

>>Radiator- need a larger radiator?

When you get closer to 300hp or for racing a new radiator would be prudent as the end tank s are plastic on the stock unit which could burst at higher pressures. Our new water pump is fantastic with a computer module sensing
temperature variations slowing the pump or speeding it up when needed out performing any mechanical pump with
a wide margin and on top of that no worries about water cavitation.

>>Obviously you can add any suspension and wheels/brake system upgrades.

It's a day's work easy..

well maybe 2 days...

would it be possible to install DEI's CRY02 system over the new intercooler?

_________________

 

maybe I am confused so help me understand.

You have a more efficient supercharger but you are still running 15 PSI. At 15PSI the only gain you will see is you have less drag on the engine so you get a few HP back from what it took to drive the old supercharger with the belt. The other thing I am reading above is that you CAN get more boost.

The only way your gonna get ALLOT more power is to change the pulley size and add boost to the 20 somthing level. You might get 10 to 20% efficiency difference over what it takes to drive the screw type vs roots from the load off the engine?

So you have been testing it at 15 PSI for several months. I am sure you have had it dyno tested then? Please post those numbers. I am wondering what the efficiency is compared to our stock one and not the mustang. Also Since you have already provided pics of the unit do you mind please snapping some pics of the unit on your test car?

Trying to see if this adds up cost wise. I am sure you understand. Thanks for all the info so far.
