Dyno Day

[gareth_oau]

Hi Polo,

was reading another thread, where Gigitt suggested the following info.

Can you please check with the dyno place to find out how they will manage AWD vehicles?

Cheers

With AWD you can have issues with bias F/R wheel bias etc
This then can induce problems with F wheels spinning at a different rate to R wheels which then can through the ECU and other black boxes into a tiff reducing power to the wheels to try and control them. Yes some cars you can turn all the safety electronics off like Stability control and Traction control.
There was a car on the dyno that spat the dummy because the driver did not turn off traction and stability control - he through codes and had all warning lights light up on the dash saying there were brakes and ABS faults etc.

That is why turning car into AWD into FWD gives a better indication to engine power.

true, but is there a safe way of turning an r32 into a FWD? I dont wanna have to change haldex after the run

Yes you can disable the centre diff we had mal's S3 on a normal dyno.

Was just reading the Syd Dyno thread & found the post Gareth is referring to.

There was an R32 there as well as an S3 in the pics, and it looks like all 4 wheels were spinning on both of them.

Might be worth a call to this place to confirm how they are setup before we lock in the booking.

was chatting to a racecar builder today and he said he gets his AWD racecar dynoed/tuned at Speedworks in Myaree

I'd like to bring both my cars along, but I've only got one bum to occupy the drivers seat(s).

Would anyone be willing to volunteer to drive either the S3 or the GT-P there for me?

heh, I'll drive your S3 up, but someone needs to take my VR6

Cheers runamuk, sounds like you have a solution!!


I could probably just about fit the S3 into the boot of the GT-P

any idea how?

[evorobin]

Not sure but it involved smoke + mirrors and a vw tech unplugging a lead I suspect...

[polo_spec_d]

I have to find a new dyno....long story short they wouldnt touch our cars so im on the hunt, could be xspeed the next place.

[MattyT]

I have vague recollections that tenegah motorsport in wangara has a 4wd dyno. Ask em!

[gareth_oau]

did a quick search

what about:

speedworks, osborne park (not myaree as mentioned earlier)
PSI performance wangara
maximum motorsports wangara
race torque engineering wangara-ish

[MattyT]

speedworks closed down towards the end of last year.

maximum do alot of Subaru work so should have a suitable dyno for the all-paw amongst us.

[geoff_gti]

XSpeed is in Myaree right? They're the ones who wouldn't do my car last time cos they couldn't tie it down.

Suggested kicking out my meshed bumper and putting the ropes through there lol (it was a joke but still...) :O
