I noticed the other day on my Gryphon CS that my Intake Temp "IAT" was at 130F. It went anywhere from 120's to the 140's depending if I was in traffic or cruising on the highway. I did install the GOTTS mod but it's totally inside the wheel well, so it's not sucking in hot engine air. I live in Florida so I expect the IAT to be above 100F, but the temps I'm getting seem really high. Thanks for the help!

 

Yeah, that is really hot. Be glad you dont have a commercial cold air intake. (emphasized for sarcasm)

1) The fender well is not perfectly sealed from the engine compartment so you will be seeing slight increases from there, but only slight because there are only relatively small holes and gaps as compared to the air's source.

2) Your fender, where most of the air is coming from, is a metal wall to the outside. If it is painted a darker color it will absorb more solar radiation and heat up. If you are sitting in traffic the panel is not being cooled by airflow like it would if you were driving.

3) What breeze you can get while sitting or moving very slowly is going to be the ambient temperature, meaning if it is 100F outside, that is what is being used to cool off the fender. That is also what your starting temperature is, but in reality it is probably even higher since pavement also absorbs solar radiation and gets hot (same as #2).

 

Thanks for the detailed answer That makes sense. So I shouldn’t worry about the high temp? I was thinking of getting the Airaid JR, but most people seem to say the GOTTS mod is just as good. Thanks again!

 

No need and wasting any money on the Airaid Jr, unless you just like the looks. I too have the GOTTS and also run the same temps you are seeing right now. Nothing to be alarmed about, just makes less power.

 

I have found that with the Gotts mod, you run significantly higher IATs when idling. It will affect take-off power, but I don't think it will matter much once you get going. It may make the engine run a little hotter when idling though.

 

I have a JLT intake and dont' see temps that high at all. While cruising its about 12* more than ambient temperature. Even when stopped its only gotten about 50* warmer ( about 120*)

 

Comparing IATs in Florida vs. Alaska isn't a fair comparison. Ambient temperature has a lot to do with how much warmer the air gets through the intake tract.

 

Yesterday (in NC) with a 98 ambient, the highest IAT I saw was 104.

This was 'city' traffic, travelling 25-45 MPH with frequent stop lights.

I have a completely stock intake.

 

50 Degree spread leaves your ambient around 70 degrees...It doesn't even get below 80 at night over here. The OP is in Florida, you'd have to cross more than a just few latitudinal lines

 

X2!....

 

I was simply sharing my data with him. Which is why I gave the change in temperature instead of total temp. I realize Florida is warmer than Alaska a little bit lol I'm sure if I was sitting down there and it was 100* out, then intake temps of 150-160* would be expected, and driving the highway would show about 110*.

(Btw, I noticed no change in driving temps from stock vs Gotts vs JLT, idling was a huge difference though! )

 

Also, they only real "Cold Air Intake" you could get would be achieved by placing a bag of ice on top of your intake.

 

Thanks for all the good info guys!! It's good to know I'm not the only one seeing these high temps. I'm sure when I get in my truck at 5:00 pm the interior is close to 130F so the fender has to be just as hot, or hotter. Makes sense. I think I'll switch my CS gauge back to TCL and quit looking at how hot it is outside.

 

Lol sounds good

 

Yeah don't be surprised. I see 130+ all day when idling in the city. All that engine air rises under the hood and gets sucked in. As soon as you do 25+ it blows out the bottom.
