CDTI - Clutches and Mapping.

[Goodluckmonkey]

Putting an '09 N22A2 (inc. a fresh set of chains) in an '04 wagon shortly to commute to work in, and will be looking to have a stage 2 map for it.

I'm in a position where it'd be an ideal time to change a clutch too (as i'd also ideally not want to open it up in the next 100k)

If the dual-mass flywheel's showing significant wear, I'd also consider changing it.
Has anyone swapped to a single-mass flywheel? and has anyone had a DMF failure? (What hp output and mileage?)

Do I just go SMF and uprated clutch and forget about it?

Or do I go DMF and OE?

I had clutch and DMF changed at 45k it was about 5 years ago when I had 180bhp, now I've got 204bhp from about 3 years and oem clutch and DMF are fine, but if I wpuld have to change it once again I will go for some uprated aftremarket or OEM ATS clutch slightly reworked

Great info. Thank you.

204hp! That's good going. Hybrid turbo?

You can make up to 208bhp on the stock Turbo and a healthy engine but it's the absolute limit of the injectors.

That's quite a testament to what Honda have built!

Must be well into the range of finishing returns by that point though?

 

[brodziu]

when mapping I managed to get 216bhp, but after 4k rpm it starts smoking as temp was to high so I decided to stay clean with 208bhp, everything is standard apart FMIC, if it will be bigger then I could get about 215-220 clean bhp

 

[Goodluckmonkey]

That's incredible.
My post above should've said diminishing returns.

At that point are you throwing loads more fuel and boost at it for small gains?
