Dyno requirements for not damaging your Turbo
Hi guys
Given the recent discussions of putting a Turbo safely on a dyno, I wanted to check if it would be ok to do what the tuner below is suggesting:
"We would remove your propshaft and run the turbo as a gt2 on the rollers. I am not keen on encountering expensive differential problems on our rolling road either. This has been my standard practice since 2003 when I was with G-Force Motorsport. "
Here's a recap of the discussions on this subject from the first Plenum thread.
Some additional details on the rolling road they use:
http://www.weltmeister.co.uk/rolling_road.htm
"Weltmeister is the UK's premier dyno tuning and testing facility, utilizing the revolutionary Quad Retarder Dyno Dynamics Chassis Dynamometer - with a collosal 2400bhp power handling capability - at the wheels. This is the largest capacity rolling road system available today - and one of only two in the world."
What do you think?

YOU CANNOT USE AN AWD DYNOJET TO SAFELY DYNO THE 997TT!!!!!
STOP THEM IMMEDIATELY!!!
IT IS AN UNCOUPLED SYSTEM AND CAN DAMAGE YOUR DIFF!!

They will probably just disconnect the front wheel drive to dyno your car. That will solve the problem eclou mentioned.

Cannot disconnect the differential on a 997tt since the stability control is not defeatable. The car then will keep applying the rear brakes to equalize the front and rear wheel speeds - eventually cooking the rear brakes completely. This happened to someone on 6speed and required an entire rear brake assembly replacement

I'll ask sportec, they've been dynoing 996tt s and 997tts (incl mine) since day 1 and that's how they told me they do it. They disconnect front the differential.. One thing though is that they cannot do it with sport mode on..only in normal mode.

I wouldn't do it Ed. The Mustang AWD and Dyno Dynamics are the only 2 coupled AWD dynos available in the US. The Dynapac and Dynojet are uncoupled and can cause diff failures. They are only safe when testing lockable center diffs like on 4wd trucks.
