[400bhpmini]

ok...well i was wondering if anyone knew wether or not BMW was maybe planning on a V6 Mini? I'm asking this and i don't even know if the bonnet is big enough for a v6...dreams dreams...
Or what about a 1.8 T??

It seems our lust for power cannot be fulfilled

[TonyB]

The M3 engine was installed a little over a year ago. It's only 330hp though... I doubt very much that BMW would even think of a V6 in the MINI, for several reasons...

Once over 250hp, the MINI enters an elite weight to hp ratio of 10:1 where only a few production cars reside:

Lamborghini Murcielago 6.370
Dodge Viper SRT-10 6.714
Porsche 911 GT2 6.940
Ferrari 575M Maranello F1 7.408
Ferrari 360 Modena Berlinetta F1 7.660
Chevrolet Corvette Z06 7.698
Porsche 911 Turbo 8.164
Ferrari 456M GT 8.429
Lotus Esprit V8 ('02) 8.694
Porsche 911 Carrera 9.393
Ford SVT Mustang Cobra 9.692
Porsche 911 Targa 9.901
Mercedes C-Class C32 AMG Sedan 10.143
BMW M5 10.210
BMW M3 10.255
=============

At 300hp, on a lightened MINI at 2,400lbs (very doable), that would have a weight to hp ratio of 8! Looking at the rides above, that is awesome. With a more efficient SC, 300hp, as I have read, is certainly achievable. As for 400+, talk with BMP about their turbo aspirations, or yes, consider a new powerplant...

As for me, I would rather have a fat 300hp SC!

Arghhhhhhh.......... Stay away from the turboooooooo...... I really don't see why everyone loves them so much!!

[moorlockx]

From early projections for the new MINI powerplant coming in a couple years they seem to be sticking to the 1.6 format for some reason. I agree with boosting it to at least 1.8. That could probably be done easily with no major redesign of the car.

I take it that engine was from an E36 then???

Only 330!!!.......U experienced 330bhp in something the weight of the mini???

The current E46 one is 343 (sad I know ) but.....can be chipped to 372 which is nice

I'm sure that wud be more than enuff for a Mini, but forget goin round bends

I'm not sure but I think there is a company out there that will supercharge yer M3 engine too

cus they don't take power to drive them maybe????

According to the designers a 1.6 is the biggest they cud fit in, the 1.6 K series was supposed to be going in there but was to BIG

also don't forget weight, it mite make it slightly faster in a straight line but less agile and we don't want that do we

Not all superchargers do!! Rotrex doesnt, also doesnt suffer from lag and runs at lower charge temps

hmmm thats an interesting concept, wots it run of then?????

I never sed that turbos dont suffer from lag or have low charge temps

C10 Superchargers
------------------------------------------------------------------------







See flow chart >>

>> General description

The C10 is a centrifugal supercharger for small engine applications. The extreme compact size makes the C10 ideal for supercharging motorcycles, carts, ultra light aircraft and other small engine application, where weight and size is important.

This supercharger exhibits excellent efficiency as well as extremely low noise and vibration characteristics.

>> Applications

The C10 is designed for two or four stroke gasoline engines with a supercharged output of up to 120 BHP approx. The use of a four to six rib poly-V belt to drive the supercharger ensures a low cost, durable and efficient transmission. Driving the input shaft directly will not affect the gear drive in any way.

------------------------------------------------------------------------

>> Lubrication system

The gear unit runs with an internal oil pump and an external oil reservoir and oil cooler. The supercharger supports all ATF types of oil. However we do recommend using our special traction fluid for better performance and reliability. Max oil inlet temperature: 80º (176ºF)

------------------------------------------------------------------------

>> Gear unit

This supercharger features a gear unit with a ratio of 1:13 and efficiency of 90-95%. The pulley size goes from 60mm up to 80mm. The gear max input speed is 15350 rpm which corresponds to a max impeller speed of 200000 rpm.

It's belt driven so there MUST be parasitic loss. Nice design though.

Let's throw a Whipple Supercharger on there

edit : WTF is up with the faces everywhere

[obehave]

More thoughts to ponder. The more I read the more I realize the Eaton was a pretty good choice.

Quote:

The only significant disadvantage of the centrifugal supercharger is that it must be spinning at a relatively high speed before it begins to make a significant amount of boost. For this reason, it is not helpful in creating boost (and power) at low engine rpms. Normally the supercharger only begins to create boost at around 3000 rpm, and the boost curve gradually and increasingly rises with engine RPM. Many centrifugal superchargers do not have a self-lubricating oil system, and draw oil from the engine's oil supply. The disadvantage to this is that you must tap the oil pan for the oil return line. However, in doing so, the supercharger becomes virtually maintenance free. Some manufacturers make a "self-contained" centrifugal supercharger that is self-lubricated like roots and twin screw superchargers.

Randy Webb reported he heard from a source that next engine (2006?) would be turbo twincam 2 liter peugeot at 256 HP.

[NEMINI]

2 liter twin cam? be nice if he's right but somehow I have doubts that would even remotely fit

[TonyB]

I just chatted with Peter at M7 today, and of the many things discussed was his twin screw SC that is getting some CNC work done now. I believe that it does have engine oil plummed through it. Should be exciting when it is ready for release...

[minimc]

Regardless of displacement or turbo PLEASE tell me its going to have variable valve timing and direct port injection!?

Is there any info on the new engine stating or suggesting that these two features will be incorporated?

... Or maybe this is just pipe-dreaming? Maybe MINI's preordained status is that of half-breed / bast*rd child in the BMW stable? ...2nd to its 100% true Bavarian kin?

Hopefully this doesn't sound too pessimistic , as I absolutely love the car! I just occasionally find myself musing about the wealth of engineering and planning that went into MINI project. ...Then I think of the power plant. While it's good to the point of receiving acclaim its still missing these two very common & useful features.

Best of the season to all of you fellow MINI folks!

[NEMINI]

one must remember the market the MINI is aimed at also, all these engineering marvels add to the price and then it will no longer be a MINI.

[PW51CAR]

Rotrex is just so easy to turn, thats why it takes practically no drag off the engine, takes about as much as an altenator would, and they do bigger chargers than the C10, think the biggest they do just now is the SP30 that goes from 64-134 model size I think, the top one is designed for 3.6Ltr engines and above but with a little work they can easily be put on a Mini, one of my mates does Rotrex kits for the Saxo and he puts the 3.6Ltr and above on them think the fastest one so far is 180 atw and thats with a massive restriction (only running 10psi) on it just now while its breaking in, will easily be above 230atw without the restriction.

Sorry red didnt mean to sound offensive in any way was just saying some points

Currently planning stages for a project begining in Feb for a 350bhp Cooper S, going to take a good few months to complete though because alot of the parts are having to be made from scratch by engineering companies and obviously thats a tad expansive, and I aint quite neveau riche (cant spell either) so can't really afford to get it all done in one go, need to space it out over a good few months. Should be pretty cool when its finished heheh really looking forward to getting it started

[400bhpmini]

well....the fact is 1.2-3 tonnes is a tad heavy for 115hp (my MC)...couldn't a small turbo do the trick?
the 1.8T of the Audi A3 seems nice to me....with the chassis our mini's have we should all have a heck of a ride??

I know what you're saying GMINI03... but I really don't find the Honda Civic and Toyota Celica to be vaulted competition - and they both use VVT.

I understand that Mini's supposed to be a bargain compared to (?) other BMW - One series et all, and thus there are spending limits. ...But it would be cheaper to have developed a power plant that had flexibility of displacement & tune. An engine which could be shared between the One series & MINI. But then there's the branding issue and that of space - which only reinforces the opinion that the engine was 2ndary consideration.

Sorry for straying from topic

I'd love to see a Mini with Porsche-like horsepower to weight ratio. The car livens up so much once 200 HP is attained. It'd be nice to have that additional bahn-burner factor.

Several MINI2 members creep closer to 10:1 by the week.

I am hopeful that folks like jlm (and his project MINI) will demonstrate for us what the current lump/blower (with proper flow) is capable of.

Good things also coming from Randy of Webb Motorsport & the boys @ Helix (Garrett chip?) and others...

Its going to be an interesting winter.

Cheers!

how about a swap involving the same family motor (Dodge) Swap in a Dodge neon SRT-4 The turbo 4cyl with a stock 240 hp may take some massaging to make happen but oh wow!!!
