Dynapack awd dyno

Recommended Posts

Hello!

 

Is it possible to dyno a 996 TT on a Dynapack AWD hub dyno?

Reason I ask is that I am afraid to destroy the viscous as I have heard that the 993 dont like Dynapack dynos.

Anyone know if it possible without remowing the front driveshaft?

 

Thanks

First of all, I am not a big fan of "hub" dyno's as they have not shown me a reasonable level of reproducibility.  Secondly, I would only dyno a AWD car intact on a four wheel roller set up, rather than trying to compensate for the hub dyno's short comings, otherwise you could end up with misleading data.

Thanks for your reply

 

I have had this dyno since 2007 and are very impressed with back to back tests. Can easily see if that + or - 1 degree of timing gives more power or not. No wheel spin, very silent, very safe since the car can not fall off, no discussions like "you strapped the car so tight thats why I have got so little power..." etc. I am very happy with the unit, but I havent used other brands for tuning, so I can not comment on that.

 

Do you think it will work with my 996 TT as a 4wd, or is it likely that I will damage the viscous?

 

I have done other 4wd cars with viscous with no problems, but have not tested the 996 yet, because of things I read a while back regarding the issues on a 993 on a hub dyno. I just bought the 996 TT some months ago and I dont wont to destroy it on the dyno...

That I do not really know as I have never run an AWD car on a two wheel dyno.  I would suspect that the viscous coupling would not take kindly to being run in this configuration; perhaps someone can chime in that has acutally run the car on a two wheel dyno.
