Ok well yesterday me and James(wankel7) got to putting one of our air temp guages into my FC. I bought a NORDSKOG air temp guage that reads from 0-200*+ F for this to be used in our intake tempereture reading tests. It took us a while to do it but we finally finished all the wiring and the instalation of the guage itself after about 3 hours!lol

Anyways i am adding some pics here and to our website later on. John is taking a well deserved break from coding. He has really done a straight up job(specially since he hasn't received a dime for his hard work)

Pics:
That is my New guage while it was still off the car.

Pic:
Guage is now installed. It took me for ever to dremel out that hole and it still looks ghetto!

Pic: Here we are idling at a stop light. kinda hot eh?

Heat SOAK!
This is what the guage read when I turned off the car. The heat was getting on the pipe and there was no more air flow on it so it got hotter than when idling!

Pic:
Here we are again at another stop light idling.

Pic:
Check out the rain!!
Won't the intake get wet? Its sooo low ........

The lowest intake temp I recorded was 83* F cruising at 70mph. Sorry I didn't get a pic of that.

EDIT:

The ambient temperature was around 75-80 last night.

Here is the rund down of our driving last night. We would let the engine warm up and then turn it off to see what the heat would do to the air inside the intake. We basically saw temps ranging from 106-110* F watching the guage for around 5 min. After turning the car off.

When we turned on the car the intake temp would slowly but surely go to 100 or below and keep falling untill it would settle at around 93-98* F. Idling at a stop light or at the Burger king.

Cruising and doing 50-90mph runs we would see the temp drop from mid 90's to high-mid 80's. The lowest temperature was on my way home driving with the cruise control on to ~70mph. We did see 84* on the highway doing around 80mph but that run wasn't too long since traffic was not clear enough for it to be real safe.

Ew! Cheap, nasty AFM adaptor! Get one with a decent (i.e. smooth) transition.

Where exactly is the temp sensor mounted? Those temps seem OK. 108degF is still a lot cooler than the engine bay temps I've measured. Try 140+degF at the filter when not using a heat shield!

BTW, next time buy hole saw.

Yeah I didn't think of that till after I was done!

Yeah well the ambient was low lower than 80 most of the time so 108-110 isn't too bad. THe AFM adapters from HIGGI are going to be ordered when I have more people in the group buy with S4's. I know its a cheap ebay one. That is why I tell people to get HKS or Higgi's adapters.

The Air temp sensor is set up after the AFM so it reads as close to the UIM as possible. It is indie the top coupler after the AFM and before the elbow.

Overall, I really am pleased with the initial numbers we are seeing. Even though it was a cool and wet day we saw a temperature difference of 25-27* F I am sure it will be interesting to see what the CAI can do on a HOT texas day where temperatures soar to 100*+. Too bad summer is just about gone. Hopefully we can get in some testing at mid to high 90's. I will be removing the CAI and testing the stock air box and a regular cone intake and the cone intake with my carbon fiber heat shield. Comparing the different temperatures will reveal how well it does against heat and the performance of other filter and intake setups.

Yep, this is Wankel7. I was really impressed with the temps that we did see on his intake. He is on to something with this intake setup.

Even I was worried about the water being drawn in. However, there was nothing in that intake. I expected to see water collected in the couplers. Nothing. There was no streaking on the intake pipes (on the inside) indicating water has been flowing by. Dry.

If I had a running NA I would be on it

Good to see some actual evidence that cold air is getting in! I'm thinking about picking up one of those guages to monitor and improve my setup as well.

Can you post a pic or two of your actual box? I can't remember what your design was!

1987RX7guy

ok he is a direct link to the site. All you have to do is use the drop down menu at the left top corner and select cold air intake: http://www.aztechrotary.********



Here is a small pic of it if you want to see more please go to the site. :



The exact part number from summit racing for the Nordskog air temp guage is: NRD-M9009

For the price is it a nice guage.

did you notice a preformance increase? I used to have a cold air intake on a honda I owned cough cough prelude cough peice of ****, but didn't notice any real preformance increase. Now I know the obd2 vehicles really detune most of the intake and exhaust mods that you put on there but I guess this might work with old 7s.

Thanks - now I remember your plans - looks good

I know the guage.... I was the one who told you about it!

Any ill effects from putting the AFM on it's side?

1987RX7guy

iTrader: (3)

Where I personally feel the EXTRA power is UP HIGH after 4-5k rpms which is, I am guessing, where the regular style intake starts to ingest a LOT of increasingly HOT air. Also the higher the speed the MORE outside air rushes around it and cools it do to heat transfer.
I have also NOTED that my car sounds a bit different with the intake on than the old one. It has a little more rumbling to it at WOT.

Santiago

EDIT:

Nick- It is not SHOWING ill effects but I am going to switch it as soon as I have time. I will be placing it upside down probably which will make it not be affected by gravity.

Hey nice on the intake and gauges, i was looking at your pics on your web sight i noticed that it went down pretty far infact part of it is showing under the bumper just curiouse arent you worried about scraping it of on some driveway or speed bump lol that would suck!!

I know i would be worried around here in UT its not as smooth as other places lol anyway nice job guys.

Please read the web site carefully!

Under the pictures there is a caption that reads something like: NOTE* In the first pic the filter is shown for the purposes of showing the location of it in reference to the front of the bumper.

Once everything is set up properly and I make the remaining brackets for it it will be flush and the underbody cover will be used again.

WHOA nice intake to bad i am stuill saving to get one not bad temp's eather i still think if u cut a hole in your hood u get better temp readings

1987RX7guy

iTrader: (3)

I am not making peeps cut their HOOD are you crazy? lol!

looks good, are you going to dyno test it. either way I'll probably pick one up

1987RX7guy

iTrader: (3)

Unfortunately to dyno test it I would have to travel about 150 miles to another city. The whole thing would probably cost US around 500 dollars for some good runs with all the setups. Sadly I do not have that kind of money.

Just remember: That I know of no intake maker has dynographs. If I can get some of our customers to send me their dyno charts I will gladly post them.

If you are interested hit us up with an E-mail. I will be glad to take any questions. Please allow some time for me to respond though. I am doing many things this week.(I am also attending a univesity so I dont have much spare time)

When will you be begin testing on TIIs?

1987RX7guy

iTrader: (3)

I have to change things around for the TII since I want the straightest shot possible the TII intake will be lower than the N/a intake.

OBD2 has nothing to do with it. The fact of the matter is that intake/exhaust mods will not do much, especially on newer cars. On older cars the exhaust is really restrictive because the cat technology was terrible. And intake mods never add much hp unless your filter is getting dirty or something.

You should get some temp readings of different intake set-ups. Get one of the OEM setup, one with open cone in the engine bay, one with cone and cold air box, and I would say with cold air setup, but you already have readings of that.

Yeah I hope to be able to crank that out by wendsday or next weekend at the latest. i will be taking ambient temp readings also so things don't look dis-proportionate if it suddenly gets hot. Yesterday like I said was around 75-80 at night but during warm days it will go up to 90's and 100's some times.

Update: About 30 min. ago I went out side to get my book bag out of my other car and put it in the FC.I turned the key to "on" so my guage lights up and starts registering temps. Like it usually does it starts jumping to high temps and slowly settles at the regular temp which is just about ambient. It settled at 75* F after a couple of min. so I turn on ther car and let it warm up. The guage takes a while and then registers 76* F I let it idle for ~5 min. and the temp actually fluctuated back and forth between 75* and 76*. It didn't go up very much only 1* F

I then came into my room and checked what ambient was(weather station and my PC's thermo app) They both said it was 73* F wooo hoo. The intake kept the temp within 3* of ambient while at idle. I can't wait to drive tommorow

nice, do some t2 tests
