Just a shout out to all you turbo fans, there is a bolt on high-hp turbo kit that is in the works for the cooper S from a Florida based company. The prototype has alledgedly put down 322hp to the wheels on a dynojet dyno(about 375 crank) on stock internals with a modified fuel system, and greddy fuel computer. The turbo is a mitsubishi unit pushing 16psi, and the entire kit with downpipe(you provide custom exhaust) will cost between 5,500 and $6,000. Stay tuned for more info on this later this year!!

 

>> The prototype has alledgedly put down 322hp to the wheels

Hmmmmmm. 322 Hp to the wheels. I doubt it.

 

I find it hard to believe that it would be possible on stock internals.


Heck, an RSX on stock internals at 7 PSI with a 2.0 is 275 hp at the wheels and 16 psi is around 312. Something seems wrong with your source.

 

>>I find it hard to believe that it would be possible on stock internals.


Heheh... at least not for more than a few moments!


320...321...322...BANG!

 

16 psi is 16 psi. If the turbo makes the same boost as we're currently getting with the supercharger, the power should be very similar. Differences would be due to the fact that the boost on the turbocharged engine will be less linear. The turbo will not peak boost at the redline, it will peak earlier. That should make less power. More power will come from either higher compression or higher boost at the high end of the power band or from raising the compression. The compression is not raised, though, if the engine is stock internally. What gives? Where did you hear these numbers?

Oh oh, time to get out the:

 

keep in mind that the blower is an engine power parasite, gobbling perhaps as much as 30 hp at full crank from what goes to the driveline.

the turbo, on the other hand, generates its boost without using engine power.

 

322 hp at the wheels?

Not a chance.

...and about the SC robbing HP - it's not enough to explain the difference. We're talking about (at the wheels) 175+ hp gain from a bolt-on.

Sorry, folks. For me this falls under either the 'gotta see it to believe it' or 'would ya like to buy a bridge' category.

 

and what's a 'Gunmetal S' ? is that DS? PS? Something custom?

 

is there anyway to get the kit installed if I already own an MCS?

 

It's very possibly, may not be driveable since the turbo would hav to be pretty big to make that much power by 7kRPM's. Also if the bottom end is built up enough its totally possible that this was on a stock bottom end, someone with a 1.8t wsa making 400hp at the wheels for quite some time before his motor let go and that was with a stock head, and block. Like I said with a good size t3/t4 its possible it just won't spool til like 5k RPM's and well who wants that

Another thing to remember about turbos (and different superchargers) is efficiency. Although boost is boost, there are other factors at work. Exhaust backpressure (with turbos), parasitic losses (with superchargers) all vary. I have seen two turbocharged cars running the same boost make wildly different amounts of power due to differences in IAT and in backpressure due to turbine restriction.

 

>>the turbo, on the other hand, generates its boost without using engine power.

Kinda like magic isn't it.

Of course the turbo doesn't generate its boost without using
engine power. That's just ignorant.

Where DOES it get its power from?

It causes backpressure, and increases the load on the engine
just like a crappy exhaust does.

No magic involved.

 

pick up some back-issues of Turbo magazine sometime, and look at the 1.6 liter street -driven hondas and small displacement mitsubishis making 400-plus at the WHEELS...Do you see them running superchargers? I don't think so. Just because the factory mini supercharger gets 16psi with the pulley does not mean that it will make similar or less power to a turbo st the same level of boost.. Do your research on turbo technology, turbos are wayyyy beyond the efficiency capability of ANY small supercharger. The Mitsubishi 20G and 25G ball bearing turbos can make more power with the right size turbo and intercooler and the proper tuning than any small supercharger out there. The ball bearings allow them to spool quickly too, so driveability is not compromised as much as you'd think. I say small supercharger because Ideally a huge supercharger that would never fit on a mini would in the end be most efficient, but when it comes to power in a small package, you simply cannot beat a turbocharger, period. 320 hp impossible on stock internals you say?? Again, do your research...The Mini S engine has 8.3:1 compression, and it also has forged pistons, and can rev to over 8,000 RPM with no valve float. It was also engineered in part by dodge and is based on a smaller version of the engine found in the new factory turbocharged neon. Without getting too technical, this means that these engines are basically bulletproof, over-engineeered in many ways, and very de-tuned. But I did say the car "allegedly" made that much power. The truth remains to be seen, but don't be so quick to jump to conclusions. The cooper S engine may be more capable than you think. And horsepower-per-dollar the turbo system like all turbo systems ever made can and will become the way to go for big horsepower. Thats all I have to say until the kit is finalized. Happy ,motoring!!

 

The power is possible. I wish i could say we had this one, but no.

The biggest problem is overall drivability and working withe the computer system(ECM).

Turbos in many ways are better than a supercharger, free HP , vs it takes power to drive the supercharger. The key to all is to have a car that has the power and the driveabilty.

good luck to all.

 

no...gunmetal S means that I have a dark silver cooper S

you're completly wrong here...a turbo's power is essentially free. You run a much larger exhaust to compensate for the turbocharger. The free flowing exhaust helps spool up immensly and lets the car really breath at the higher RPM's...the turbo itself causes no parasitic losses to the engine itself, meaning spinning the compressor will not make take any HP away from the engine. The only thing that could and sometimes does is the excess heat, but with a proper intercooler this can all be kept in check. A turbocharged engine is much more efficient

for more info e-mail me, the shop is in FL, all installs will be done there, after final testing is done. We are campaigning this project with a race team, but there will probably going to have 3 stages available. E-mail me at Rokitpokit@aol.com

 

Trippy...? What the heck are you trippin on dude? Must be some bad acid cuz I work at a shop where we do nothing BUT turbo upgrades on many european and japanese cars. What you just said made absolutely no sense...I don't think turbos care about ignorance. YOU are ignorant if thats how you think turbos work. You really think that turbos "create backpressure like a crappy exhaust" How about I give you Turbonetics' phone number and YOU tell them that!! Better yet I won't, I'll save you the embarassment. Go learn how a turbo really works first before you make yourself look like a fool posting something like that, seriously.

 

Hmmm, why is there no discussion of a turbocharged Wankel engine for the Mini?

I still think this would be the magic silver bullet.

 

Mike, thanks for also not agreeing with Trippy's logic :smile:

Jay...NOW you're talking!!! A 2-rotor turbo in a Mini,that would be something to see!! It wouldn't be too hard...HMMMMMMMM...:smile:

Have youse guys heard about the VTEC Mini? They are putting them in classic Minis and there are efforts underway to put it in the new...
VTEC MINIs

 

I thought the wankel took up an enormous amount of space? I could be wrong, but when you look at the skeletal pictures of the rx-7 and rx-8 the wankel and tranny take up a huge amount of hood real-estate. I wonder how you could stuff that into a mini. Would be sick though.

Now a K20A in a Mini would be an incredibly sweet thing. That RSX-S engine is a true jem and a half. Heck the new detuned 2.4 in the TSX is a beauty too.

I still find it hard to believe, but you wouldn't see me complaining if you proved me wrong. In fact I would welcome it.

Someone I think that much power on a FWD car would effect daily driveability slightly, but I would love to hit a nice, reliable, controlled, and non-lagging 240-250 hp. :smile: Is that asking too much? Is mid-12's in the 1/4 too much?


Rofl, would love to see the look on the service man's face as he chokes after opening the hood too. :smile: Even better with iVTEC!! Lol, get your car serviced at an Acura dealership! Now that would be trippy stuff!
