Dyno Results For Factory Standard Xr6t And Xr8

[VII13B]

Hi Everyone,

I am just a few days away from becoming an owner of a 2004 XR6 Turbo Ute.

Just wondering if anyone has seen any results from facory XR6T's and XR8's on the dyno. Just wondering how close the factory power claims are to what they are actually putting out.

Any info would be appreciated.

Thanks,

Matt

factory my t went 194.5rwkw hope that helps

Ok thanks. So it is losing around 45.5kw through the drive train?. Seems like quite a lot. I didn't think it would be that high.

Remember the factory 240kw (BA) and 245kw (BF) ratings are measured at the FLYWHEEL not the TYRES.

Thanks Falc

Yeah I realise those numbers are quoted at the flywheel. Just did not think there would be so much loss through the gearbox and diff.

Have you raced many 8's? If so how did you go?

[MrBean]

There's approximately 22% loss through the drivetrain, so 195rwkw+22% = 238rwkw - quite close to factory spec.

This is assuming the 195rwkw is the average, it amy be higher, or lower.

If you had 200rwkw, which should be closer to the norm for XR6T, you will be sitting at 200+22% = 244fwkw.

So yes, an approx 40kw loss seems to be acceptable for drivetrain losses.

yep, mine went 192rwkw stock.

I had a little play with an 8 the other week... no contest, then again, my car isn't stock

I got pumped by a BF XR8 few weeks back.. but turned out it was supercharged though

[Mildman]

Mine measured a little high and had the dyno operator pretty excited. 245rwkw BF T Manual. I'm assured his dyno was accurate....but you be the judge.

I was able to flat shift through the gears as well, which is meant to be impossible in a manual T (Unedited) so who knows maybe I had a police tune or something...
