Dyno results. MAF data would be good I guess, if the test vehicle is on a stock tune that is. and of course if the dyno runs were done back to back.

We (SARX) all sat in traffic idling waiting to get into a big event last Saturday and we all saw IAT's in the 150F range when ambient temps were around 90F. Two of the cars had AEM/MS intakes and were right at 150F with me (turbo) and the highest was 165F+ in a stock (engine wise) R3. One had the RB but he got separated from us so I wasn't able to see what his IAT's were. I wish I could have.

I guess living in the desert would cause that. I lived in Palm Springs, CA (grew up there) and it would be anywhere between 100 and 115 during the summer.
When I drove my 8 from CA to DC it was 112 one day, but I didn't check my IAT to see what it was. Couldn't be any cooler that 112 and am sure it was way higher...
Cold air is hard to come by in high heat

Hay guys... Chiming in.. on the intakes... I have had the following...
Stock
AEM CAI
RB Duct and intake kit.
Stock with RB Duct K&N Filter
Stock with RB Duct Baffles removed K&N Filter
Stock with RB Duct Baffles removed and Screens removed K&N Filter
Stock with RB Duct Baffles, Screens Removed K&N Filter and Duct cone thing i fiberglassed up.
AEM or RB WITH THE DUCT is by far the best method.. All the stock variations where ok. and the the intake cone I fabricated was ok.. It worked better than stock in higher RPM 4-5k range seemed a bit more responsive over stock but that was it. the AEM and RB feels much more responsive over that as well. in making that cone the result is not really worth the labor.
but it was a fun little project and it was nice to test out the idea i had.

I am currently on the RB with duct and its simple and an easy way to go that provides honest results... Does anybody have any independently done test results on the SR motorsports intake??

I have seen their dyno chart on-line in the past but I do not see it on their website now. My obsession with the MAF sensor data is because, if we are switching intakes around for the purposes of power increases and such, any changes in the torque curve would be presumed to result from a measureable change in the incoming air charge and that change would evidence itself in the MAF sensor readings. I am not so sure such readings would have to be done, necessarily, on a factory map as long as whichever map was used was not changed when intakes we swapped.
As for intake temps; the experts in the alky injection industry have told me that intake temps, in general, are not a concern until they are above 150F.

Same old results as any other intake thread..... if you're looking for power increase then there are better things to put your money towards. Certain intakes may delay heat soak but if your in traffic long enough your gonna see high temps regardless

40th anniversary Edition
Go with the AEM or Mazdaspeed CAI (actually the same piece) . I have had a Mazdaspeed CAI in both my 2008 40th Anniversary RX8 and my 2008 Mazdaspeed 3 GT and both have been bulletproof. A performance improvement with better breathing and denser air. I have owned seven rotary Mazdas since 1973 and several have had CAIs. The AEM and Mazdaspeed model has been the easiest to set up correctly and a completely troublefree CAI. If you can still find the Mazdaspeed version (and they are getting hard to find) you will get a Mazda warranty. But even if you go with the AEM, they are so reliable and easy on your engine, you should have no problems. Enjoy !

If you're set on getting a cold air intake, do NOT get anything other than Racing Beat's, AEM's, or Mazdaspeed's intakes. Everything else is a complete rip off and you will LOSE hp and mpg. The stock air box is already really good so you won't gain much at all, but I would recommend getting the AEM or Mazdaspeed intake. The AEM and Mazdaspeed intakes are actually the EXACT same thing so It's up to company preference/what deals you can find online. I personally went with the AEM intake just because amazon had it for $300 plus FREE one day shipping. It's funny, even the AEM intakes have Mazdaspeed engraved in one of the tubes.

Brettspeed had input into the work sock setup but it will be sold under the "Slidespeed" brand. I just bought all new work socks so I will have approx 10 Sock intakes up for sale on a group buy very soon, as long as they all pass my quality control tests of course ( not too many holes, not too thin ect)
