I went to the track last night and ran horribly, lol. I KNOW I need a tune, and will be getting one soon enough, but I've also noticed that my charge pipes and IC->throttle body pipes are pretty warm most of the time. I have planned on getting my hot side of my turbo, and my downpipe all jethot coated. That should help some w/ engine bay temps. It seems like i'm going to need something else to get this bad boy to cool down some. Anyone running any kind of intake cooler system? Like a nitrogen spray setup on the IC or anything? What could be some options for me to look into?

Ohh and btw I ran a 12.77@113 w/ a 2.0 60' on 22lbs.

The plenum and IC pipes will be hott. (even to hot to touch) That doesn't necessarily mean that the temps are going to be warm as well. Intake temp gauge/sensor is the only way to know.

85 degree F day. Mine were 29-30 degrees C at the starting line then 32-33 degrees at the 1/4. Then slowly cooled back down to were they started. Keep in mind I couldn't touch my plenum w/o getting burned for long...

Jet-hot coated exhaust manifold made a world of difference, moreso than a downpipe would. I can set you up with my old manifold cheap if you wanna send one out and not have down time.

Power FC won't log AIT. However, if you have datalogit I am sure you could figure out how to rig up GM air temp sensors with a 5v feed to read the air temperature. Sounds like a good idea, maybe Ill try it.

Evan

yea, wasn't sure about the PFC...i'll just rig something up w/ the datalogit or something to see.

What kind of manifold is it? I have a T4 flange on mine now...i can take it off and have it all coated fairly easily. I have a gredy intake mani w/ a FMIC, so no heat soak from there...just under the hood, lol.

Just throwing it up...as FYI

I really think you should get it coated, it made a very big difference in my underhood temperatures..

Evan

You should be able to find a curve for the GM AIT sensor somewhere on the net and use 5v to log it. Lemme know if you bother to do it, I am curious to do this as well.

I.e. they change resistance with temperature.

So to log it and make sense of it will take some knowhow.

Can't just feed it with 5v and expect to get any meaningful data from it.

1) Buy the GM IAT
2) Either find the temp vs. resistance characterization. OR just measure it yourself by sticking it in different temperature environments and measuring the resistance.
3) Next you will need a solid +5V source and will need to look at the characterization curve and choose a good bias resistor to get the resolution you want through your specific temp range.
4) Mathematically recharacterize the Voltage out (with your now bias resistor) versus temperature... so that in your logs you know what voltage corresponds to what temp.

After reading, I stand corrected. PLX does make a unit that you can wire right into your power FC 0-5v input if you are so inclined.

Decent thread here on honda tech;

Just make sure you're not detonating and egt is inline

i'm not detonating...i know that.

I know the car needs a tune, badly...but thats not going to drop my intake temps...I guarantee that they are hotter than it seems like. I will get it tuned shortly, and then i'll install a intake temp gauge, and we will go from there i guess.

Maybe- maybe not, cooler egt's = cooler exhaust manifold=cooler engine bay temps.

But the reason for wanting cooler charge pipe temps is for cooler cylinder head temps right? That's where a tune would help.
