Ok, i posted a thread not too long ago about charging my pop charger filter with cold air from a ram air tube. Well, here is what happened...I drove to chicago yesterday and it was about -2 degrees Farhenhiet. I got up on the free-way and drove for about 20 minutes and pulled into a gas station to fill up. I popped my hood open and felt my throttle body. It was freezing! I was litterally sucking in -2 degree air into my intake and my whole throttle body unit was very cold to the touch. Who know's what my intake temps were....can this be bad? How cold is too cold? Could it hurt my car? Thanks for reading guys...

 

AS far as I know, the colder the better! Don't worry about it.

 

what about your car running leaner??

 

I'd be more concerned about water and oil temp. Oil has to be a certain temperature to work most efficiently. I think it might be as low as 165º. I'd be surprised if you have a problem there. Water temperature might be more critical to watch in really cold weather. That's why truckers have those covers that can zip up to close various sections over their radiator, so they can affect how much cold airstream is hitting it.

 

My car does take a lot longer to fully warm up now....so is this bad??

 

That's what the MAF and 02 sensor are for. If I ever get my intake, I'm going to do something similar. I can't wait. You gonna be in Indy any time soon?

I'd say that if it takes forever for the car to warm up you might want to consider synthetic fluids (oil & transmission anyway) for better protection at cold temperatures. It was 5 degrees this morning here in southwest OH and my car had no trouble staring or shifting gears (the shifter was actually pretty easy to move) thanks to Mobil 1 and Redline As long as it doesn't seem to crack anything (ie hot air inside engine and cold air outside) then I don't see how it can be too bad for the car -- it should make some more power in the colder air, or so I've heard.

 

You have a point...you can never be too careful. I wonder how you can actually measure the intake temperature?

Badaxxima - yeah, i'll be rollin' through this weekend...gotta hit up IIP for some lights.

 

Th throttle body has a hose running coolant through it. I thought it was for this very purpose. Or did you do that mod and take it off?

Can you please post pics and/or do you have a write up for this? Maybe I'm confused and have read of this before. But do you have a write up??

dwapenyi - i didn't remove anything..

 

In that case . . fuhgetaboutit. I'm pretty sure that Maximas in Alaska are the same as the ones down here

Yeah for some reason we all got those weird hot coolant lines running around the TB. Never could figure out what they're for. To prevent high-speed freezing of the throttle maybe?

Str8ridin, what exactly did you use for the ummm... "funnel" again? (I hope the answer just isn't "funnel" )

 

Many folks have nitrous systems that inject LIQUID NITROUS OXIDE into the intake plumbing. How cold is that? I wouldn't worry about ambient air temps, no matter how cold it gets in SW Ohio. You've got a couple hoses running [hot] coolant through the throttle body to keep it warm.

 

Reassuring words...

BMAN - I used a plastic gutter spout and connected it to a small oil funnel (which I moddified to largen the opening) which is then connected to the hose. All of it can be found at a harware store.
