Air Intake Wrap, Is this stuff worth it? Options

[TRDDawg]

I have heard that the insulation or intake wrap lowers the temperature of the air in the intake by 15 degrees. Is this worth to buy? I think a kit costs $50. How much hp do you gain by using them on your intake?

If you buy it and send it to me just for June 28th weekend...I will tell you and send it back. I'm going to a place where the dyno is really cheap to run on that day.

my intake pipe gets burning hot. so if it prevents it from getting hot it would probably prevent power loss with build of heat instead of adding hp

Yeah well I am going to get intake tubing with insulation already wrapped around it. I don't know when though. so I can't send it in.

Hi,

Any insulation that can reduce radient heat will help with HP.
The problem with radient heap swap or soak is that once she gets hot she usually stays that was unless you get some cold air flowing in and over.

Meaning if you are driving in traffic then heat swap will occur & takes longer to go away then form..(Unless you turn the engine off and let it cool.)
Thats why you always have this great power gain in the morning on a winter day....until eng heats up too much.

The other thing to consider is are you runnig a metal intake pipe from the inj manifold to the air filter.
A lot of after market models look great and come in many colours and shapes but radient heat from the engine creaps along the piping heating it up and the air that travels thru it.

I would recommend keep the rubber factory one if you can and wrap it in heat proof foil or foil tape..!
Also piss off any high flow exposed pods and put box back with a high flow filter, but run a 2.5 to 3 inch pipe(wrapped in foil) from under the car up and into the bottom of the air box to get flowing cold air thru the filter..insead of dead air from the side guard.

Cheers

Do you have any pictures of the intake that u have?

[CelicaSX]

I'll try to get the camera under the hood & see if I can get some clear pics for you guys.

Considering that intakes only add about 1 HP (to these low-end motors), wrapping the intake will probably help by adding an additional 0.1.

Well thats the same as a K & N drop in filter.

[ghostdog]

come on ray, be nice. 1 hp isn't fair. mb 3 at the most... lol

"The first pull on Friday showed power at 92.4 horsepower with a stock air filter and stock exhaust system. (1.1 more than pre-rebuild). Looking over our notes, we noticed that the last pre-rebuild dyno run was with a K&N drop-in air filter and the ECU recently reset. We popped the K&N air filter in for the second run, which yielded 93.7 horsepower, with a consistent gain from 4000 rpm on up. The ECU's fuse was then pulled for approximately 30 seconds and the car was run again, this time showing 95.3 horsepower and 103.6 lb.-ft. of torque."

Ok... fine... 1 + 2 = 3.

Now let's factor in the extra 2 ponies to my last comment. So that would maybe about a 0.3 increase in HP by wrapping the intake (or possibly at most 0.7). hehe

"dead air from the side guard"? If you were to compare the air from the side guard, and the air from the bottom of the car, I believe you would find absolutely no difference in temperature. Don't fool yourself, you can't get anything close to ram air effect from an intake, no matter where you put it, and the side guard is far from a airproof box.

[CelicaSX]

Yes you are correct in what you are saying, but under the hot sun & heak soak from the engine block the inside of the side guard is more than likely going to be a little warmer than the air you get from outside the car. Plus if your pipe is facing the filter the air moving over the pod helps keep that end of the filter business a little cooler from radient heat from the engine....bit like the radiator.

[HyperDeathKill]

Ah yes that's true. I don't know how much cooler the air would get, but every little bit of HP counts. Actually, if you remove your fog lights then air can directly hit that spot.
