yup I loved my Helix FMIC.
Former....you realize that you cant directly compare any test I did and test you did right?

But I still think that the intake temp makes a significant difference, albeit much less of an effect than a larger FMIC. Using the calculator if the input temperature is 100 degrees the IAT (plenum temp) is 121 degrees, so this would simulate stock or a "cold air" intake like RR, UR, injen that attempts to draw in cooler air. Compare that to an input temperature of 135 degrees the IAT is 131 degrees. So if you are using a DCI that is drawing in air that is 35 degrees hotter than a "cold air" intake type setup then you have a resulting IAT that is 10 degrees higher.

Again, I'm not saying a cold air intake is more important than an FMIC for lower IAT. The upgraded FMIC is going to lower the IATs more than the intake, but if you alredy have a bigger FMIC (like me and many people on this board) then colder air into the intake will further decrease IATs.

Now, put 135 in as the IAT.Press enter on the first tab. Then Press enter on the second tab. You get 131 degrees F. 121131=10

I will test your CAI if you send it to me and log runs to show you are simply wrong.

really? damn, all the turbo race cars I see must be wasting their time pulling air from outside the engine bay then.

Are you kidding me? We are not a race car and they are looking for tiny advantages over long, long runs. Do the math and you will see. I will do that testing to prove it if you send me a CAI. Helix already did the testing, but no one will listen. Look at almost every supra with gigantic T72s or T88s and you will see the same thing. You guys just won't listen even when facts are placed in front of you!

You at least mentioned that race cars are looking for advantages, so that must mean a well designed CAI has its advantages...no? I want advantages too, but maybe thats just me. now if the CAI design chokes the turbo's b/c it doesnt allow enough air to flow, then thats a bad thing. Best case scenario  cold air intake with ample flow (can we agree on that at least?) as for the Supra's.....a lot of them are running a straight pipe out the passenger headlight to suck in ambient temp air. Please dont tell me this is for a ram air effect. This is at the track where the headlight is not missed, but if you could do this on a daily basis and keep your headlight obviously they would. For street driving the owner of this Supra removes that black coupler and the extra pipe and puts his cone filter there. such as:

Sniz, if the temperature difference was 50 degrees, then yes. I can tell you after data logging AITs for a long time now that the only difference you will ever see is when the engine is standing still for a while. Once you pass any air across this Active Autowerke intercooler, then AITs drop to within 1015 degrees of ambient every single time.
