very cool and idk what you're concerned about that's as clean as you could ask for...great job

and just wondering what did you do to make it look like a red bull can? just a decal or what??

 

Good info, I appreciate the time and effort put into gathering the data and posting it up. I'm also running a PRM, but just cut out the fake AP2 brake duct on the passenger side. Eventually I plan to run a duct tube right up to the PRM air horn. The headlight mod is so balla, great work man.

 

Thanks I got good feed back from some local members over the weekend from the meet, I guess it doesn't look as bad as I thought! I just wish the ducting blended in a bit more on outside

It is just a big Redbull can trimmed up and stuck on to it I hated just seeing the can hanging there. Not to mention all my guys are domestic guys and always make fun of my high strung little toy... Can explains the high strung to them

No problem. I thought about doing that but I am partially concerned with hydro lock hence I didn't go with an AEM style intake but it is a long run and I wanted to make it as short as possible, but I do also plan on doing some brake ducting this winter. Not sure if I will use the AP2 bumper inlets or just go into the main grill area with a larger intake I'll cross that bridge when I get there

 

well if concerned about hydrolock could add the aem bypass valve somewhere along the tubing before the throttle body.shouldn't effect heat to bad should it?

 

The IAT sensor on the '06+ AP2 is in the intake duct, which I believe is a better spot for testing improvements like this.

 

Ahh... I didn't know that 00-05 is mounted in the Intake manifold.

Would it be a better spot? I would argue that it depends on where the car is actually reading from to make it's trim adjustments for air temp. In the duct then the test should be in the duct, in the manifold the test should be in the manifold. The goal is to affect the sensor that the ECU is using to make a decision on the trim.

 

I don't know which location would give a better IAT for the ECU to use for ignition and fuel trims, but it seems intuitive that the intake manifold would be better. However, for the sake of testing the net result of a modififcation like the one you did, I believe an IAT sensor right in front of the throttle body would be best, since it would eliminate the error associated with the intake manifold.

 

Great work, I'd love to see how it compared to the oem intake system for a comparison. Thanks for posting.

 

 

Cool thread. Im always watching my IATs as well. I have FIPK but have always toyed with the idea of wrapping the box and tube with gold thermal tape. From my experience the biggest factor in IATs is ambient temps. It may be possible as well that the IAT sensor is suffering from heat soak itself not giving an accurate or up to date reading of true intake air. From a cold start, the sensor seems to reflect accurately the temp outside when compared to other thermometers for what its worth.

I generally see 38c to 60c cruising, however on a side note im not entirely sure that high intake temps are the cause of bucking some complain about.

a few thoughts/questions:

Does anyone have data on how adding a header or removing the manifold heatshield affects IATs?

Has the OP thought of adding a heatshield in front of the engine, between the intake?
