Now that I've got my ScanGauge installed I've been watching the Water Temperature and Intake Air Temperature (IAT). This morning with an outside air temp (OAT) of 71F I had a moving IAT of 110F. While sitting at a traffic light it went up to 118F. I'm not sure I want to check it this afternoon when the OAT is supposed to be in the 90's. I'd say the MCS is a great candidate for a Cold Air Intake. I didn't start monitoring my old Yaris until after I had a CAI installed, but IAT was never more than around 15 above OAT when moving. So a CAI should be a cheap source of increased power for this car.

 

I was just reading on this or another forum that some generation of MINI ran cooler in Sports mode.

Did you have to enter Volumetric Effeciency or Brake Specific Fuel Consumption?

 

I could see where the Gen 1 or Gen 2 Minis might have run cooler, but I don't know what the Mode would have to do with it.

All I had to enter was that I wanted to display intake air temp. Nothing else enters into this. The heating above ambient is pretty much a function of engine compartment design and airflow thru it. My guess is the Justa has a lower temperature rise (cooler engine compartment) based on the smaller block size and heat generated. But maybe it has a better Brake Specific Fuel Consumption than the MCS.

 

The Justa is just better! :-)

This one!

 

Interesting thread, but a totally different topic. I was referring to the temperature of the air feeding the turbo and entering the engine. It seemed the intake air charge temperature is awfully high in the F56S. And since cooler is better and translates into more HP, I believe the S will benefit a lot if a Cold Air Intake can actually reduce this temp.

While I monitor Water Temp on my ScanGauge, I expect some fluctuation in temp but in a narrow window. I've found my S runs pretty tightly around 220F unless I really start to push it. If anyone else has a ScanGauge or individual gauges I'd like to hear from them to compare readings whether they have an S or a Justa.

 

I'd think a bigger intercooler would be better to keep the IATs in check than a CAI. The process of compressing the charge-air greatly increases the temperature. Remember PV=nRT?

 

Wait where is this IAT being measured? Pre or post turbo? Pre or post intercooler?

 

I don't even care about the extra performance. I just want to hear that turbo spool up.

 

I second this! Also, wondering if things would be helped temperature wise if you made the hood scoop functional?

 

What he ^^^ said.

A couple of degrees one way or the other at the intake of the compressor isn't going to mean diddley. "Cold air intakes" (Where were they getting all this WARM air, anyway? Even the most modest of vehicles I've seen has an intake duct that runs to either the front or side, away from air heated by the engine/radiator.) are one of the great sounds-good-on-paper scams foisted on motoring enthusiasts. You'll notice that there are doggone few before-after dyno results on these things.

If this really keeps you up at night, find a larger aftermarket intercooler and/or arrange for more air to be ducted over it.

 

I'm seeing the same results as you are with my MCS and Scan Gauge II. I think Mini could of been a little more creative with the air box. Maybe they're setting us up for a JCW air box.

 

Papa - Can you post pics of the gauge setup in your car? Would love to see how and where you mounted them

 

Did you use the same exact ScanGauge to monitor IAT on your Yaris?

Different IAT sensor, different sensor location in the intake, different intake design, different vehicle, one with CAI (Yaris) & one w/o CAI (MC) - maybe not a accurate comparison. But comparing the IAT before & after the CAI installation on the same MC would be an interesting finding. And yes, a forced induction engine would benefit from cold air intake for sure.

 

You may hear it since air would be a bit denser!

Seriously though, I've done CAI modifications on 7+ cars in the past since early 80's (first was the 1980 Celica 2.2L)) and barely ever noticed a measurable improvement in performance or fuel economy, but then I never dyno-ed either those cars. One thing I certainly noticed was the LOUD intake noise, and that kind of gave me an illusion that I was getting more performance. And, in all the cars, the air filter was located just behind the front bumper or next to the fender, far and away from the exhause as much as possible (in other words, you can barely see the filter when looked uner the hood). Yes, they were mostly home-brewed CAI. But MC might behave differently, who knows.

I usually do 3 basic mods to gain performance out of IC engines - intake, exhaust & ECU tune (jetting if carbed!). In my experience, exhaust and ECU tune gave the most noticeable gain in performance and fuel economy. But as I mentioned, who knows, MC might gain some. Let's find out!

 

The Scan Gauge has an "X Gauge"feature which is Mini specific. It uses all the stock sensors via the obd II port

 

now that the MAF sensor is actually a fixed part of the air box, bolting on a simple CAI isn't going to be as easy as it has been in the past.

Someone is going to have to design one to accommodate the MAF sensor and do quite a bit of testing to ensure the car likes it (MAF's are highly sensitive to proper airflow going over them)

 

Just velcro'd it to the dash. Set back just enough so the steering wheel doesn't block my vision. Routed the cable out the back and down the door jamb area to the connector below.

 

I realize the differences between R56 and F56 are literally all encompassing, but when I put a CAI on my R56S it made a massive difference in the volume of the turbo. It was bliss. I hope it's the same for the F56 because I can't hear the engine at all in my Justa.

 

on cars with forced induction more air (volume) is more important than cold air. For keeping IATs down an upgraded FMIC is good. Aslso adding water and or water/meth injection is usefull too.

 

Does the job. Thanks for posting.
