How much effect would a slipping clutch (pressure plates) have on dyno for NA XR6? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I was just wondering if having had buggered pressure plates in my BA NA XR6 would have affected its dyno results? I realise it loses a fair bit of power at the rears on the road (I know this for a fact, especially the last week) but does this translate to dyno results? Basically I am curious as to whether my current dyno results (with slipping clutch) are accurate or should I get it dynoed again after the clutch is fixed?

I mean, it's not like I have a heap of power in the NA to start with, so finding a bit more would be nice!

Thanks

The simple answer to all of your questions is "yes". Depending on how bad the cluth is slipping you could be losing 10-30%.
Think about what it is doing on the road and then translate that to the dyno, which is really a rolling road.

Yeah, I thought so.... I mean I know it is kinda the same as being on the road, but I thought the dyno would somehow compensate for that. It is slipping constantly though, even when gear changes are way passed..... I can really feel the loss in power on the road, it has gone down hill really fast lately too - a few weeks ago I could only pull level with an auto AU, but now I reckon I wouldnt even come close to doing that even.... I can actually feel the engine wanting to do things that are not coming out at the wheels.

I am not sure how bad the clutch was when it was on dyno though, so who knows.... but at least it should have a bit more power once the thing is fixed!
