Has anyone foundout how the GP gets the extra HP out of the engine ? Is it new cam,or ECU flash,better exhaust or anything else? any info would be appreciated.

 

thats 8 hp over JCW 210. Check on motoringfile.com. The info is there. If I remember right its SW and headers.

 

i thought it was ecu and IC.

 

It also has a bigger supercharger!

 

WHAT? That's the first time I've heard that, unless you are joking.

My guess is that if any of the new owners were to check their actual horsepower on their GPs, they may have the basis for a lawsuit.

Let's wait and see.

 

I heard the same thing.

 

I was bored and searched:
http://motoringfile.com/2006/02/27/t...-kit-in-depth/

"Modifications to the intercooler on the compressor and the electronic engine management increase engine output on the MINI Cooper S with the John Cooper Works GP Kit to 160 kW/218 hp clearly symbolised by the throaty sound of the twin-pipe sports exhaust."

 

So does that mean they played with the sc? There's not a whole lot you can do to the intercooler w/o it being pretty obvious. And what could they have done to the sc? The only mod that would be cost effective would be to tweak the pulley sizes, which might make sense being the the JCW pulley is not even a full 15% reduction.

 

 

Larger intercooler = 8hp??

Just a question...

 

The Ic Cover Is Also Redesigned To Flow More Air, Providing A Cooler Intake Charge.

 

I totally see how this new IC cover could provide at least 1-3 hp!

 

The IC is covering the spark plugs so it is surely larger.

I can see a 8hp increase with a larger IC and ecu tune.

 

Yep, just feel the difference on anyone who has an aftermarket i/c, esp in cooler climates!

 

Modified IC, New ECU program, modified Supercharger, changes to intake system. I'll let you know when I pick mine up this weekend in NJ.

 

hmmm... that pic of the gp makes it look like it doesn't have hte lower radiator that my 06 mcs has. I have the one that the new m7 air diverter goes on top of and this gp looks like it doesn't...

any ideas>?

 

Yes, that GP doesn't have the airconditioning radiator installed.
I saw 5 GPs at the Sandia Motor Speedway in Albuquerque on Thursday and they didn't *seem* to have 218HP...but then again, the owners weren't letting the locals who knew the track behind the wheel! Good thing too.
They look cool, that's for sure.

 

Power is nothing without control

 

Thats right. The JCW 225 Kit adds the headers.

 

they bumped the red-line a few hundred RPMs. That makes a few HP. The IC is larger, reducing pressure drop accross the core. The new cover doesn't really do that much, but if they didn't make it no air would get to the back of the IC! There are no changes to the SC itself....

YUP ...

The GP horsepower rating is at 7100 RPM compared to 6950 for the Works kit.

Also, the 218 HP rating is metric horsepower which equates to about 215 ponies

 

So, can we flash our ECUs with the GP software and get the higher RPM? I could then put my Unichip back in and get more HP...
(my guess that someone has tried this already - I'm never the first.)

cheers,

 

I just bought the GP IC, it has exact the same dimension
like the ALTA and GRS IC´s.
The best about it is the price - only € 148,-!!!!

 

Amazing price, considering the stock intercooler lists for $250 and the JCW intercooler cover lists for $170 in the US.

Did you have to replace the underhood air duct which seals to the top of the cooler?

Please provide the part numbers.

 

I bought the GP IC too. The cover of GP IC costs 116 €.

+ 55 € for assembly material (underhood air duct )
