Intake Pipe Gets Hott

[totalreborn]

i have a weapon r secret intake connected to an air duct ((in hopes of getting some cool air in the filter)) and its great good air flow and makes a beautiful deep tone..but the thing is the aluminum piping gets very hott from heat coming off the engine and warms up the air going into the motor thus lessening the potential of my intake...i heard theres some wrapping or tape to keep this from happening...any one know where i could get it or is there any other solutions

You could use the tape or you could get ceramic paint. You should have just done a DIY. With weapon-R you are paying for looks.

Depending on how hard you run your car, the intake pipe will get somwwhat warm, especially if it's a short ram(it's just the heat from the engine). I have a CAI on my 97 5sfe and it gets warm every now and then, the only time it gets hot is when I autox. I had a Weapon-R Dragon intake and I had the same problem. At least you are getting more air sucked into the engine. I would not worry about it, you are still getting some cool air into your engine VIA the duct work. Thats about all I have to contrubite.

There are complete wraps for intakes that lace up and everything... look around at various import stores. I think I saw them at Options.

Edit: Here

im constantly down the high way at 120..and the intake gets very hott haha...so ill probably get ceramic paint or the tape...thenx

^ Jesus... glad that you can drive recklessly

Be more careful please. You're still a young kid... you get pulled over going that fast, you can say goodbye to driving til you're 21.

NJ is like the speeding capitol. I haven't done 120 but they do speed a lot. 120 on a constant basis is ridiculous. Forget the license lasting till 21 the car won't.

don't worry...he'll learn like I did....8 points on my NYS liscence and a close relationship with courtrooms later. Glad he isn't in NY. and for the record, Akimoto makes aheat wrap for intakes in various sizes for your intake. Oh and try to explain a 120 mph speeding ticket anywhere....you'll def lose your liscence

[CrawlingEye]

Stop speeding.

Now if you want good info, the heat wraps aren't worth it, nor is your intake.
The best way to cool down the temp of the intake itself is by bypassing the TB coolant lines. It's actually the lines that run to the IAC.

I've done this, and with my CAI+ceramic painting and with the bypassed IAC, you can't even tell I've driven in the car, no matter how hard it's being run. My friend and I did some quick WOT tuning with my S-AFC II a couple nights ago on the highway (late at night, no serious speeding, just WOT then slow down, then WOT again). After the whole trip, he was very surprised by the fact that my intake was in fact cool to the touch.

Stop speeding and bypass the TB coolant lines ... my intake is always fairly cool even after a while of driving since doing it

[totalreborn]

how would i do that??

[Super Kaioken]

120 mph!?! dang i saw that on Gumball Rally lol! only in europe!!

Bypassing the coolant lines didn't make any differance in intake tempature, or any real noticeable differance in HOW LONG it takes the intake to warm up. (v6, not little i4)

If you don't want it to be hot when you touch it, you need to break down and do what I did. Make a spacer for the entire upper-intake air chamber. I did mine from aircraft grade plywood with a spare gasket and a dremel.

The entire upper intake is touchable after an hour or two of running without being close to "uncomfortable" tempature. DO NOT confuse this for being "cool". It's still warm, and can get hot... It just normally stays warm (compaired to scalding), and takes a very long time to reach a scalding tempature.

Phenolic plastic would be a better way. Wood tends to start burning between 450-520F depending on what it's make up is.



I said upper itnake air chamber spacer... NOT throttle body... There is a *huge* differance there. One actually works and is usefull. The other is stupid and people that have them get made fun of.

im constantly down the high way at 120..and the intake gets very hott haha...so

That's very... The wrong impression you're giving everyone.

The intake get's hot becase the engine is running. If you ever actually watch tempatures in the engine bay / engine / coolant / oil related, once you get between 40-60mph, the tempature drops from the increased airflow. Not jsut because the car is moving through the air, but because the pressure differances on surfaces grows exponentially.
I can tell you the temps on an ES decrease a bunch between 55mph and 70mph, then 105-110mph.

I would almost go as far as saying the tempature of the engine bay / engine / coolant / oil related would be LOWER on cruize control at 105-110mph for 10min than it would idling for 20.

The point I'm rambling about is you're engine isn't running hot because you're driving 120mph... If Toyota would actually calibrate the temp gauges to be useful, you'd see it varry during driving around town, and driving on the highway. But they don't... Most people worry when the temp gauge doesn't sit in one spot. (I blew my radiator on the itnerstate, drove another 30-40 miles and the needle didn't move).
Yaaaa Toyota! A tottally useless gauge LoL!


(Take a volt meter to the ECT sensor and watch it as you drive around for a few days... You'll see it!)

^^^^hey stop encouraging him to speed...

i'll admit i've done 125 a couple of times but in the late evening (2-3am secluded highway, so the only person i'd kill would be myself ) but not all time. I guess u'll figure out sooner or later...

considering CAI's dont make much HP (actually free it up) i can tell u it's not noticeable if u wrap it in heat tape or whatever...
