I just got back from a little ride... got on the car a few times, nothing to redline or anything.

When I returned, I popped the hood and felt around the intake. The passenger side was hotter than the drivers for one. The radiator hose is HOT and part of it being under the passenger side airbox might be an area to help cool things off... the tubes going to the intake manifold are also pretty warm. Keep in mind that it's also only 60 degrees out today and very windy... my oil temps never even got to 200 degrees even getting on it.

I think that i'm going to cover pretty much all of the intake areas at some point just to be safe. The boxes weren't hot, but you can feel they are well above ambient temp.

Did you check interior temps on the tubes?

My new HPS post MAF tubes installed

This is from another thread where the internal temps had been measured...

Yup, I referred to this post somewhere back on page 4 before god knows what happened and we veered off into brake ducting and 5.0 hatred.

this is interesting... but from someone who has only 60 posts and i'm not sure how accurate his set-up is... I would still like to get more measurements.

Jordo!

That corroborates with what I've seen logged via Osirus uprev. 60 posts here doesn't mean he doesn't know about cars -- sounds like he has good datalogging devices on hand

You may be able to bring IAT's down some with additional shielding, but in practical terms the major benefit would be seen staging at the drag strip rather than on the road.

That said, if you are curious and want to tinker, the easiest solution might be to pick up a good OBDII datalogger cable that can be used with software on a PDA (e.g., the auterra) so that you can datalog changes in airtemps and get good estimates of mean temps with and without extra shielding over a range of circumstances.

no no, this was just a pop the hood and sort of feel around where I could feel the most heat... the passenger airbox most definitely gets hot with that radiator hose close/under it though... the drivers side was surprisingly much cooler, but like I said, this was most roads being 40-45 mph with little engine load. I did get on it on the highway a bit, but this is only about a mile stretch both ways and then it was back to another 10 minutes of the lower speeds. For being only 60 degrees and very windy, it was warm... on a 90 degree day with heavy engine load I can only imagine.

Iat's are somewhat separate from straight tube temps.


The heat conductivity of the plastic is very low, although the plastic is somewhat thin so you see some heat transfer.

With the stagnant air in front of the inlet, though, you see a huge iat spike when sitting. You can alleviate this a little with ducting, but for the most part it is unavoidable.

lol oh hell no... i'm not running anymore wires or laptops or any of that crap in my car... i'd rather just shield everything and know it's ... well just cooler lol.

not gonna happen, no money in the Budget, only way is if we can find a way to trim some money somewhere else to offset the cost of the beer and travel expenses.

jordo...i guess we are a dying breed....

Pro Tip: Keep more than a 1/4 tank of gas in the car.

Red__Zed

1: no one tracks with a full tank
2: about 5/8ths full when it happened
