Exactly my point. Even on the 997TT, they are much more pronounced than on our cars.

 

+1, yup they make ours look tiny!!!

 

You have mail.

Motec... You're going all out.

 

Yes sir. Email sent. Thanks Steve!

 

You can barely see them if you are looking at it from the front.. look like little slits.

 

IIRC, the 991TT IC ducting is actually fairly small despite the 'scoop' being more pronounced

 

This is most likely done to increase the speed of airflow over the IC. By enlarging our intakes, we would effectively be doing the same exact thing.

 

A lot of great contribution to this thread you have created Pwdrhound.!


If this was me, I would scan the current intake with this cheap scanner,

I would design a formed prototype to the scanned image and double tape a 3d printed prototype to the cars current intake and log the change in intake temps.


Maybe create two models, one very extreme (ugly) and, one at the minimum (very cosmetic.) Swap between both designs within a few runs back to back while logging the Intake temps.


You could also use "flow design" from Autodesk to create a controlled environment simulation but, real time data in this case should suffice with environmental variable's.


Just some of my "Food for thought."

 

I agree, perhaps testing could measure pressure differential in the duct pre/post IC...and maybe compare with 997 as well to show the variance in flow due to body/duct design, since they share the same IC's....

 

Let's chat this week. I forgot you have access to all that fancy equipment. Might be of some help here. Thanks!! One way to test these would be to install the inlets on only one side of the car and measure the speed/volume of air flowing through each duct. The side with the inlets should show greater flow. If that was the case, we would have a confirmation of a successful outcome as greater air flow = greater cooling = lower IATs! IATs could also be measured on the respective sides post each intercoolers. I think Earl could do this as his car was set up for this during the intercoolers testing he's done.

 

Not sure how you could measure each IAT bank. I cant with my current setup. It only measures the IAT as a whole prior to the throttle body.


Guess this would be the next question in order, where are the intake temps censored? Does the Maf record this?

 

Earl had a set up where he had a IAT probe inserted in each side of the Y-pipe so that he could record the IATs on each side to compare the two different intercoolers he was testing. No, you could not do this on a stock set up. I thought IAT was measured at the throttle body but I may be wrong..

 

Need more info on Earls setup. Sounds great for logging.


on my 997, I have an intake sensor just before the throttle body. Not sure on the 996.

 

interested on a set as well!

 

Understand now, thanks. I'm still interested to see what you come up with.
