VII13B Member 38 Member For: 18y 4m 24d Posted 03/02/07 09:28 AM Share Posted 03/02/07 09:28 AM 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 Link to comment Share on other sites More sharing options...

VII13B Member 38 Member For: 18y 4m 24d Posted 03/02/07 10:38 AM Author Share Posted 03/02/07 10:38 AM 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. Link to comment Share on other sites More sharing options...

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? Link to comment Share on other sites More sharing options...
MrBean Member 400 Member For: 18y 10m 28d Location: Melbourne Posted 03/02/07 12:01 PM Share Posted 03/02/07 12:01 PM 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.

Mildman Member 149 Member For: 19y 4m 23d Posted 04/02/07 11:53 PM Share Posted 04/02/07 11:53 PM 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...
