Hi

Yesterday i went to Finlant to http://www.amworks.com/eng/index.htm (near here isn't very much 4wd dynos), beginning all work fine and we make a soft test run/tires warm up, then mechanic sprays litle glue in to tires and we are ready to get numbers, but front wheels aren't any more running fast, mybe 5km/h, when rear ones are 50km/h....in test run front ones seems to spin as fast, as rear ones...
We wait ~20 minutes and tried again...same thing...front wheels aren't moving...
So I get no dyno graph....
He had dynoed plenty 4wd audis, subarus, skylines, evos, etc ant porsche was first car, what doesn't give reading :s
Can anybody say what was reason why front wheels aren't spinning on 4wd dyno?

 

same here ! i try to dyno my two weeks ago ! same

 

I pulled the front drive shaft and dyno'd as a rear wheel drive car. Pulling the drive shaft is easy as long as you can get the car a foot or so off the ground.

Same problem happened to me while trying to dyno. Gotta change the car to RWD for dynoing it seems...

By the way, when are you coming next time to Finland? Perhaps we should meet! There's some nice Turbos in Finland but of course it's a rare car...

 

So I need to convert then to rwd...
Kaizu I let u know, when I come to finland

thanks for replies!
