hello,

Does anyone have experience with fitting a header on a Cooper s?
Not just connecting to cat. But fitting in the the engine compartment without mod. I have also seen pricing from $200-1k for it.

Planing on doing this with Thumper head and cam.

Cheers,
jb

 

There is not a header for the R56 S. I have an aftermarket exhaust manifold that I am going to be installing once I get my Bentley Manual. There is one the WMW offers for $350.

I know a couple guys running this header and are very pleased. The price is definitely right!

Not on an R56S...

 

I dont see there being large gains on stock turbo with a manifold upgrade.

 

There is no proven gains at the moment but, you can not say that there is no benefits from some better exhaust flow. With beeter flow there good be lower turbo lag.

 

I am planning a larger cam and head port and polish that is why looking at a header now.

 

Again...the R56 doesn't have a "header"

Exhaust/turbo manifold yes...but you funds are better spent elsewhere (ie. on a different turbo) especially if you are doing headwork.

 

+1

 

point taken on not much gain for header, others are saying the same. Still think other reasons like increase air flow and maybe a bit of sound improvement would still be a plus. also went into my thinking.

 

You probably won't hear much of a difference in sound with that turbo in the way...

 

Apparently you are not understanding that there is not a header on an r56 S

 

you will lose power and tq with a tubular header on a street oriented turbo motor.


For a street driven car you want to keep the exhaust gas hot ,for a track only car that operates within a narrow powerband
a tubular header is the way to go.

 

How is my old downpipe working for you?

 

AWESOME!!! Love it. I had to cut up the stock heat shield though. No big deal as I plan to replace it with WMW one.

 

^^header




^^Turbo manifold.

 

Alright so the R56 has no header, but does have an exhaust manifold. Then what? The downpipe is directly connected to the manifold?

 

Manifold -> turbo -> downpipe -> exhaust

A turbo is essentially a pair of turbine wheels connected by a shaft. As hot air escapes the engine and hits the turbo, it expands and spins. This spinning turns the shaft, which spins the fan on the intake-side of the turbo, compressing the air that's entering the engine. The "increased flow" that you're looking for is in the downpipe that you've already installed.

There's not really anything gotten out of swapping the manifold unless you're installing a larger turbo.

Here's a cool video I found explaining some of this stuff:
