Default intake heat shield?

i read the diy short ram intake heat shield and i really wanna try this inexpensive mod. is it worth it? has anyone done it and felt any gains? or is it just a waste?

waste get a turbo! seriously all the money you put into these little mods saved up can pay for half of your turbo. just my 2 cents. whats the mod say use exhuast wrap? in that case your keeping heat in.

Bah, once the hood is down all the engine heat will disipate all over the engine bay, Obviously the farther away from the enginie the cooler it is (cold air intake) But with just an aftermarket intake, your maybe gaining 1-2 hp at the most. I wouldnt bother with fabbin up some nice heatsheild when the gains of such a task would be very minimal and you would probably never feel a difference. just my two cents

heatshield wont do much, at speeds above 30 there is any hot air really under there anyway

you might squeeze a few real ponies doing a tune on what you have now and beat the same car you drive w/o tune. but i dunno what you would use to tune your engine you have the f22 right?

...let's work on our thermodynamics a little more. insulation doesn't care which side the heat is on, it just restricts the flow (from higher to lower temp)

anyways, cheap and easy... several coats of barbeque grill paint or high-temp paint. this will reduce heat absorption through the aluminum piping (and i think it looks slick...). but it only helps if you're getting cooler than underhood temp air in. this means CAI or fab up a filter box through to ambient air. i chose the later..

lets work on reading skills alittle more, you are correct insulation doesnt care what temps its insulating, if you read the begining of the ops post you would have seen he has a SHORT RAM intake.. I can assure you unless you live in alaska with a CAI is the only time youll benefit from insulating your intake pipe, and even then that mod will still yield you maybe 1 ponie to the wheels. like previously mentioned ITS A WASTE OF TIME.

Now go home and put your high temp paint all over your engine so you can have a colder engine bay.. peace duesch.

Took me 15 minutes to cut bend and seal the heat shield that I had. Did I notice any gains? Not in the seat of the pants but I have two data logs that show the difference in my IATs. Data log 1 without the heat shield has them reading between 31.7°c and 37.2°c. Log 2 with the addition of an engine bay heat shield shows IATs of between 14.7°c and 18.4°c. That is a difference of approx 18°c.

Is it worth it, I'm not 100%. I didn't have the car on the road long after I made this modification to see any MPG gains. Nor did I have it on the dyno.

I'm sure one of the people who said that the differences aren't worth it should be able to tell us, What little gains are to be made in MPG or Hp with an IAT difference of 18°c?

Just a note to my above post. This mod was done on a 96 Accord chassis. In the end it made my $30 SRI into a CAI. The shield/air box that I created allowed only the cool air from in behind the wheel well cover to enter. In doing this mod I also didn't have to worry about having my air filter below the bumper line. Therefore I had no water worries.

good info Ghost, how did you log the IAT temps? So basically your car ran as if it was winter time constantly w/ the heatsheild mod .without having to do the "FAMOUS" mod for the IAT sensor. I researched the IAT sensor mod and played with it for awhile. it made my 96 accord run like it was winter time constantly dunno any horsepower gains though. interesting info.

I logged them direct from the ECU using Crome pro and a second log with logworks2.

I wouldn't say it ran like it was winter all the time. My IAT's were always close to the outside air temps coming off the road. I recorded these logs in the spring of 07, the day before I took my car off the road. So the outside temps were in the mid to high teens that day. The fluctuations between 14 & 17 was dependent on if I was driving on shaded streets (cooler) or sunny streets (warmer)

As far as I know there is no way to make the IAT's colder than the outside air temperature without the use of a cooling agent. ie, ICE or A/C of some sort. You cold pack the insides of the air box with bags of ice. I've seen that done once on a drag car before.

On the IAT sensor as temperature decreases resistance increase, im sure u seen that when logging right? Well the mod on the IAT sensor is inserting a resistor (99 cents at radioshack) between the two connections. you have to look at your manual and see what the IAT sensor will allow, there is a range that if you go over it will have a CEL. I cant remember which one worked for me but it fooled the computer to think it was like 30-40 degrees outside. I say run like winter 9colder days) because when its colder outside the engine feels alittle stronger then the hot summer. thats the only difference this mod makes.

Have you looked at what the IAT hack is actually doing to your AFRs though? A stock ECU that sees your resistor hack saying the IATs are 30°F-40°F (-1°C- 5°C) will add 5-7% more fuel and your timing will not change. So if your actual IATs are in the 70°F-80°F (21°C-27°C) your running warm air with a 5-7% richer fuel mixture then you should be. So you may or may not see any gains from doing this. Probably not going to do much on a stock engine other than lowering your MPG and adding more of that black suet to your bumper. You still physically need more air for the 5-7% fuel increase to be a benefit.

There is no electronic substitute for real cold air. There is a reason your car works and feels better in the cold air. Tricking your ECU to think it's colder out doesn't do the same thing.

interesting info guys. idk im just trying to squeeze power out of what i have now. i wish there was someone who knew if there are any real gains though.
