Tuners and people with experience with dynoing the 996tt please chime in here. What is the best procedure to dynoing my car? Where should the fans be located? Should the car temp be warm? Should a pull be done and then shut the car down to cool down? Anything else?

Thanks

Come on guys - Ill attach a pic to get some more interest

 

why is ur rear lid OPEN?

 

From what I have seen having that orange fan rite up against the outlet of the IC's and forcing air backwards across them is the most important thing.

Having the geartrain fluids hot will help. Make sure your oil is at operating temp before doing a pull.

 

That what the shop did. But anything else you can add

 

why would you not want to leave the trunk open? you have to let the heat escape since you're in such a closed environment.

i've run mine numerous times. try to get some fans up front too to get some air across your radiators.

the intercoolers have already been discuessed.

finally at least one scroll fan blowing the on motor too. bottom line is that you can't get enough air flowing around your car while in the shop on the dyno.

 

But do you want to one run and then shut the car down too cool off?

 

yes, try and get around ten minutes between runs with the car off and the fans blowing on the car. let it idle for a minute or so before you shut it off after the dyno run.

your dyno operator should know how to do this though.....

 

Thanks and I will tell him to do it this way next time.

 

Also what gear pull is reccommended?

 

4th gear. that should yield the best results. just make sure you use the same gear everytime from here on out to get an accurate comparison when you go back again.

 

Thanks again - so far you and jean are the only one that helped. Where are all the tuners at Todd? Stephen? Neil?

 

On the front of the car, we do one in the middle and two one each side. On the rear, we open the hood and point one at the intake. We will also point two at the rear intercooler ducts and cool those as well. We get about four runs and then the car gets too hot to produce accurate results.

Hope this helps.

 

Wow, there is no air movement going on there. What we do is pull the bumper and place the two fans in the ducts. The car is run from 2K to redline in 4th gear. We have two fans in the radiators and another center fan that moves about 60mph air over the nose of the car. The AC doesn't matter since it switches off during WOT. Cool down is idle for 3-5 minutes. We also leave the deck open and run another fan over the top of the engine bay.

 

Thanks Stephen
