I merely stated a fact. I am not being confrontational. I know this is a forum and we are having a conversation.

The JCW engine and drivetrain is very different from a Cooper S. It is a lot more than an upgraded turbo and pistons.

I am merely repeating what Jan told me when he tuned my car. That flutter is there from a map lifted from the ECU of the MINI Challenge car. It keeps some back pressure in the turbo so that it does not need to fully spool. Therefore the turbo has more power available on the next shift.

It is very noticeable on my car because I have the NM Engineering hard pipes that delete the muffler on the hot side and the noisemaker on the cold side. I also have the DoS intake. All that combined makes for a lot of engine music that gets transferred to the cabin.

I like it. I think it sounds great.

 

Oh no its not, the engine differences are, Exhaust manifold, Turbo, Exhaust downpipe, Pistons, Air box/intake tube, Spark plugs, That's it.

 

don't forget the muffler itself. I love my fat pipes sticking out the back

(i guess technically it isn't part of the engine)

 

Sorry "czar" you are rather misinformed.

Engine
-More aggressive ECU tuning
-Turbo back exhaust system. The exhaust and catalytic converter have been reworked and enlarged to aid the unrestricted flow and reduction in back pressure. Also NO second cat.
-Upgraded turbocharger - larger and strengthened twin-scroll turbocharger and exhaust manifold resulting in a pressure increase from 0.9 to 1.3 bar
-Upgraded pistons
-Upgraded Getrag transmission
-Upgraded clutch and throwout bearing
-6 speed manual only

Upgraded engine components: The engine is fitted with reinforced and specifically ground pistons as well as a cylinder head with optimized rigidity and modified gasket. The cylinder head wall thickness is increased to reduce potential stress during peak output. The intake valves and valve seat rings are also made of a specially resilient material, and compared to the engine of the MINI Cooper S there is a slight reduction in compression.

The air filter, air mass sensor, exhaust system and catalytic converter have been modified so as to achieve a power-enhancing dethrottling on the induction and exhaust side. The through-flow capacity of the clean air duct to the turbocharger has also been increased.

BRAKES
4 piston red Brembo brakes with painted JCW logo and larger rotors, red rear calipers and larger rotors
12.4" rotors-front
11.0" rotors-rear

DTC (dynamic traction control)
EDLC (electronic differential lock control)
17" Challenge Alloy Wheels.

Different enough to make a difference.

 

..........

Sorry onefish, I think he's more informed than anyone on the forum.

 

Thank you Thumper.



Thank you for your information above ^^^^^ about the JCW model differences to the S, however I am aware of the model differences.

I was simply referring to the differences in engine components between the JCW and the S, and I have not been misinformed, I have examined both engines side by side in my workshop.

 

Whatever. I am done with this thread.

 

This went from hardpipes to people pissing on each other because they think they are right.

 

Anyway, referring to the WRC cars...

I didn't JUST say WRC cars, but they too do it. A lot of street guys do it. The GIAC and Unitronic aggressive tunes for the GTI and 1.8T Jettas both keep the BPV nearly closed during shift, resulting in turbo flutter.

A lot of skyline guys run closed systems.

A lot of Subie guys run closed systems or extremely aggressive tunes that keep a lot of boost in the system between shifts.


As for the JCW... The turbos aren't much different. The JCW turbos are k03s with k04 internals. So it can take a little more air. If I was just making a street machine, I would much rather start with the lower tag on the S and work from there. k03/k04 hybrid for 800, bigger intercooler for 5, hardpipes all around for 6, custom turboback exhaust for 5. Tune for 800. That's $3200. Tag on another $300 just in case I'm wrong about some prices. $3500 to smoke a stock JCW... compare that with the $6K price difference.


...Just sayin.

 

Anybody mention the K&N intake yet? It has a hard pipe with K&N filter enclosed in a fabbed box. I haven't installed mine yet but shall report when done

 

OneFish2,

Could you provide me with the title of the youtube clip that you have posted on here? Since i am at work I cannot view it since I am using work's computer, but i can watch it using my iPad on the youtube app.

 

First 2 videos...
