Octy RS - Dyno results - stock as a rock

[DanSA]

Had a chance to get her on the rollers today with some of the Renaultsport boys.

She went well and posted 132kW at the wheels - very happy with that considering 30% drive loss :cool:

So we have a base line now.. :rolleyes:

Mainline dyno, 4th gear, ambient of 22 deg. Running BP98. Will post the curves when i have a chance to scan it.

Nice healthy motor..

Thats impressive...

Don't they only make 147Kw @ 5100rpm / 280Nm @ 1800rpm as per manufactuers spec?

Looks like you have a live one there!

Well done!

[DanSA]

Correct. I put it down to a healthy engine and good run in process. :D

Dyno seemed to be on the ball too, as some RS Clios where making 98kW as they should (124 at the fly) and Megane 225's 140kW ish ( 167 i think at the fly)

Old skool Sierra RS Coswoth put down 187kW at all 4 :o

Alpine A110 a nice 68kW from 1600cc air cooled out the back.. Looked sweet :)

Here's the results of some Vagcom logging I did, yesterday as it happens - stock as a rock also. 24.5 deg ambient temp, third gear.

I measured several things at once, so each measurement only occured about three times per second. The torque figure is a theoretical value produced by the ECU based on the crank angle sensor, and the power is calculated from this in Excel...

I don't think that FWD has 30% drive loss - my AWD Liberty had that much.

Having looked at a few dyno results & using the bum-dyno on my old Golf I'd think they lose 15% at most (but closer to 10%).

15% - fwd
20% - rwd
30% - 4wd

Rough guide! :)

Well the MK3 2.slow gets around 92hp at the wheels with a rating of 115hp at the crank making it a loss of 20%, I'd say its 20% anything less would be optimistic to say the least :frown:
