Well its odd for this time of year for us to get cold weather, but right now i just checked the weather last night and it said it was 39 degrees outside, the past few weeks its been 80 during the day and like 65 or so at night.

Last night, i decided to tune the car for the track wednesday. I was running 8-9 psi, but decided to bump her up to 10.5 psi.

Well it was extremely cool out, and the car was running like a damn champ. I decide to do a few datalogs w/ the ems just to see what kind of intake temps i was running...

At crusing speeds my AIT's were around 85 degrees F. in 40 degree weather, you'd think thats hot, but in reality when you figure the heat the intake manifold is going through at crusing speeds, its a damn good figure.

When i got on it, its fun to watch the AIT's drop pretty damn far. The lowest I saw was 59 degrees F which id say is pretty damn good.

Now two weeks ago, in about 70 degree weather, i did a couple datalogs as well. while crusing my AIT's were about 105 degree's F, when boosting, they dropped to a low 91 degrees.


While in higher heat, the intake temps only went down 13.3%
whereas in the cool weather the intercooler was more efficient to the point of 30.6% cooler.

and we all know the cooler the air, the more dense, the more power

I found this stuff kinda interesting, and thought Id share.

 

interesting...I never gave it much thought that the intake temps would go down as you pushed the car harder. I learned something

 

What gauge do you have? What's the intercooler setup?

Thanks Mang...

 

I use my laptop for all my "gauges" except for my afr, i have a techedge wideband so thats the only display i have besides my laptop.


The intercooler is a HKS.

 

Is this with the sensor in the stock location?

(Heard it helps to move the sensor off the mani to somewhere prior to the throttle body).

 

so you have the iat in the charge pipe? I need to put mine somewhere...its just hanging off my harness

 

interesting find

 

no this is stock location in the intake manifold

 

Thanks mase, i'm gonna put it in this weekend. Hopefully get that headgasket changed also.

Well i've also decided that i'm not gonna sell my car just yet. Gonna tune it, dyno it, track it, to see what kind of potential its got. Most likely still gonna sell it tho. I just want a different car...more comfortable ride.

 

thats what i wanna hear

 

I notice a huge change in power and gas mileage when the temp is 10 degrees here.

Yesterday is was 60, damn my car was slow as ****, but I get hella good mileage now.
