Intake temp difference
 

Hey guys I have this thing about the intake temp, what is a good intercooler and what would the Intake Temp be. When using the Pfc what is a good efficent intercooler and a good intake temp reading in a twin turbo setup?

It depends on the ambient temps and the usage. There many good intercooler setups, all of which have pros and cons. Please do a search for FMIC vs SMIC vs v-mount...this has been discussed ad nauseum.

Intake temps should be below 40C in most circumstances.

I installed a small digital thermo on the outlet of my stock IC, (just to see how effective/ineffective it is). Idling in bumper to bumper traffic on a 28 deg C day the IC outlet temp can get up to and over 70 deg C.

really? i have m2 medium and m2 cf intake (arguable the best setup outthere) and in the summer (june july august = 75-90 ambient) i rarely see intake temps of or below 40. I am talking hwy cruising too. city or nonhwy driving is almost always above 50 degrees. Now in early spring and fall i will see 20 and 30s.

forexample sunday was 85 F ambient. HWY temps were 45-46C while city was 54-56 C as measuted by the power FC

Ha! Maybe in Alaska.

The air filter inlet air would be over 43 here and an IC can never cool down to amibient. I think an intake temp of 56 C is good

Location of your air temp sensor makes a difference. In the stock location under the UIM, it heats soaks there and gives false higher readings . Move it to the IC outlet neck or throttle body elbo.


Heat report from Houston. Yesterday afternoon the air temperature was about
35-36C/96-97F, driving in slow traffic of 35-45mph, my engine air temp was 39C/102.2F, and water temp was 87C/189F. I have a FMIC.

Agreed ^

Since I moved my IAT (intake air temp) sensor to the output neck of my FMIC I seldom see IATs of over 40C in normal daily driving.

It is interesting that I was checking some things yesterday and had run a datalogit log, the results are real close to Chuck's

Yesterday was 92 F/34 C here in lovely southern Illinois with a humidity of about 80%.

In town coolant temps never exceeded 88 C (although in slow traffic and at idle I was looking at 84-86 C) as measured by my PFC and 191 F as measured by my Nordskog digital coolant gauge. IAT's were between 35 and 36 C / 97 C. (point of interest... sometimes it appears my IATs are LOWER than ambient temp by 1 or 2 degrees C. I really need to get some time to check that out more closely).

Running down the road at 90 mph after a couple of good spirited accelerations at .93 bar/13.5 psi to raise the temps I saw 208 F/93 C coolant temps and IATs were around 41C/105F.
