R55 Cooper S

[CoolHands]

Are you replacing the turbo oil feed / return pipes at all? You know the feed one gradually gets blocked up cos of heat. You can get oil line types instead of hard pipe if you want. I intend to change mine at some point. Also thinking about changing my oil pump chain too as it’s possiva but noisey.

Keeping them stock for now, they are clear, I did soak them in gunk & blew them out, may be a job in the future.

2.5" stainless cat back exhaust just bought, something else to fit. May not be ready this weekend now but might as well get all the spannering done in one go.

Arch liners and headlights, exhaust (new shiney one) top up oil, and fill the coolant and I think it will be done!

Go on, show us the exhaust!

Should sound pretty good with the new DP and the exhaust

Okayyyyyyy, daft question / have I done something stupid time. Is a Standard Cooper S exhaust stainless and 1 piece from the downpipe to the back boxes? I have a funny feeling it already has a go faster exhaust on


Oh and it running like a good-un :-) Seems very raspy (admittedly I have the cobra downpipe on) have a sneaky feeling it is an after market exhaust. Just have it idling at the moment to burn off all the oily bits off the engine, garage is a bit smoggy.

Quick OBD scan reveals no codes, happy days. Being a tight git I may wait until feb 1st before I tax it, if I can, will see.
Anyway, this should be a video of the exhaust, is it standard?

Had a proper poke around under the back, seems it is a mini exhaust, will get the new one fitted up

[GaryF]

Tremendous progress.

I have the standard JCW exhasut on my R58, bar the DP which I swapped out for an Akrapovic 100 cell cat as part of the Lohen Performance Pack 2. The exhaust sounds absolutley lovely now - raspy and with some occasional pops and bangs (when not in Sport) but not at all hollow or boomy.

In Sport, it's a bit too poppy and bangy, but fun for short bursts. It's the map that is doing that though in the main, so it will be interesting to see how yours goes on a standard map ad how much power you are getting. With the DP and the AEM induction kit mine was dyno'd at 239 bhp before the Manic map on top of that, so you may be somewhere about there.

Did you have to mess about with the headlamp fittings? I replaced one on mine and it’s a bit of a faff. I guess it will have to be put on an alignment machine now (mine as well as yours).

Didn't need to move the adjuster mounts so hopefully they ill be okay, will check on the garage door.

Is that a JCW? if so what was the increase over stock?

[scrw.]

Well after discovering its a stock exhaust...it has to go LOL. And I can confirm swapping a 1 piece exhaust with a car on axle stands on your jack is bloody hard work!

Had to cut the centre section rubber mounts, so will need to fit some tomorrow before I finally get it all set up and wind down the exhaust clamps fully, not quite 100% happy with the back but no point messing until the rubbers are all in place. My cheapo ebay exhaust seems to fit okay, only idled it so far, a bit late for giving it some beans, will have a play tomorrow during the day.

What diameter is the new exhaust over stock?

Yes sorry, mine is a JCW rather than S. Standard is supposed to be 208/211bhp depending on what you refer to I think, so a decent jump with the DP, AEM induction kit and the Airtec intercooler in place for that reading on the dyno. Here is the chart for reference :-


Map C (the most powerful one) gave:
269.7 BHP
380.9 Nm (280.9 lb ft) with peak at 3864 RPM

Your new exhaust looks good quality from what can be seen in the pics if it is just "a cheap ebay" number - the pics are a bit blurry, but put that down to your hand shaking like a leaf having had to manhandle the old one off and new one on single-handed whilst on stands

Camera on my phone seems to be having a brain fart of late, blurry photos are becoming common :-/

Exhaust seems good, however not keen on the clamps that come with it, having to torque up with a breaker bar to get enough bite on the exhaust to stop it slipping.

front rubbers on, exhaust all tightened up. Not 100% happy with the exhaust tips, one is about 10mm further out than the other, but they are central in the bumper (despite not looking so in the photo below). Last job is to fir the cowel under the alternator, a job for later.
