Here are some data sheets.


Boost Curves



EGT



Intake Air Temp



Regarding IATs:

We are measuring via the OBD sensor which is in the intake pipe on both cars. Therefore, we are unable to measure the true temp right before the intake valves on the GT2 where the expansion chamber is. However, look how hot much hotter the IATs are compared to our 700S kit! There better be a lot of temp drop going on in that expansion chamber to make up for the high IATs! Hmmm....

 

nice stuff there Mike. Make sure you post this for the rennlisters too!

 

Already done, baby!

 

wow, looking good

 

So let me see if I understand this.

GT2 VTGs produce more boost, 1.4 bar, but also more heat. Air induction cools air (not sure how much) but also drops boost to around 1.0 bar.

The more you use drive, the more heat is absorbed in the engine, turbos, etc. Hence, the more you drive, the less effective the air induction will be.

HUH?

Does this seem like a cat chasing its tail?

 

damn that car is sick...looks so mean.

that stock exhaust is a nice piece from akrapovic...i have an akrapovic on my sport bike and the quality is absolutely top notch.

 

hmm many problems with stock car. Imagine modified turbins with bigger air wheel and 1,55 bar boost which I'm running.
I decide to install turbo intake back.

 

Mike,

AWE 700S kit compared to stock GT2, it is the one for the 997TT right?

Cheers

Subscribing. Definitely want to track this bad boy...

 

You are correct!

 

LOL!

 

My friend send me comment to this measurements:
"Hey Karol ,

I thought the temperature data of the AWE 997GT2 dyno was interesting. ( for a dyno run that takes maybe 5 seconds )
I wonder what the temperature would be for a 20 second dyno run?"

 

First, our dyno run sweeps take about 12 seconds.

Second, tell me the last time you were able to hold full load for 20 seconds in one gear on the street or track.

Third, since a 20 second pull is far more loading on the engine than one would ever see on the street or track, the fact that there is not a chassis dyno fan set-up in the world that can exactly mimic real world air volume and velocity at that roll speed becomes even more of a factor.

In other words, doing 20 second long single gear pulls on a chassis dyno is loading the engine for an unrealistic real world scenario, which means the data gathered and the tuning done for that environment is meaningless.

A chassis dyno is for simulating real world conditions. Too many tuners lose sight of that and take all their data out of context and begin to tune for the dyno, not how the dyno represents the real world.

 

you should try 0-300km/h run, than you will see how hot it will be.
So Olaf Manthay GT2 is finished. 603Ps and a bit over 700Nm with secam intercoolers, ecu and performance katalic converters.

 

Karol I did run mine (AWE 700 kit) 0-300kph at the Texas Mile. High ambient temps and 30kph headwinds. Car ran consistent 185-186mph in a standing mile all day long.
