Hot air intake - Toyota Nation Forum : Toyota Car and Truck Forums

Wibbit · 05-28-2004, 01:35 AM

ok this is the problem i have: having a short ram intake makes the car run fantastically when the ambient temp is cooler or when during the first couple of min of driving... after that it sucks up crappy hot air and the car gets all sluggish and the exhaust gets louder... that really sux!

i dont really want to buy a CAI or make holes in my bonnet and id like to keep the pod if i can. i have a little so called 'heat shield' but it does jack all

do you guys experience the same thing? what do you guys suggest??

you can make a cai!

or buy the obx one for 80 bucks:

because our camrys are v4s... makes me a little suspicious about the quality/fitment of the product, if nothing else... anyone have experience with them obx cais?

Stock air box, K&N Filter

(hahaha, anyone from the other thread must hate me right now

)

make a cai...it costs around 100$ with a new filter

hey i have heard that this might work. take sum dry ice and put it on the air intake. my friend did that to his eclipse and it kept that engine nice and cool so maybe it will do the same for your air intake.

but wouldn't that flood the engine with co2 as that what dry ice really is??? compressed solid co2?

you could use the stuff that they sell at shoe stores to remove gum. it freezes the gum off your shoe and hair. my buddy 3yrs ago had a gts and he did that alot.

yup, carbon dioxide, which is pretty harmful...

i'd say maybe create a special "dry ice tank" next to the intake, and let the dry ice cool the intake...

but then again, i think it'll get TOO cold, and freeze the metal...

Wibbit · 05-29-2004, 04:04 AM

really? too cold you reckon? the engine bay is pretty warm, the other half of the intake will prob suck up the hot air. anyway im not really too keen on adding more carbon dioxide to my intake...

im think of jus buying another intake with a full heat shield and cold air feeds, the BMC one shown by the link is i think a good option, its also included on our Ford Falcon BA GTs i believe

Being a chemical engineer and reading this thread, I'm going "WTF???" the entire time. Dry ice??? What, you're gonna keep refilling your engine with it every few minutes after it frickin' evaporates or something??? Yeah that's a great idea. Dry ice tank? Dude if that's somehow supposed to keep the CO2 from flooding the engine bay, that ain't gonna do shit, cuz when dry ice evaporates, the CO2 expands, and that nice tank of yours is gonna explode. I'm pretty sure that shoe people use liquid nitrogen for their purposes. You're going to run into the exact same problems with nitrogen. You'll just end up flooding your engine with an inert gas. Way to go. Either way, dry ice and liquid nitrogen are ass expensive for the consumer level unless of course, you have a machine to make your own. But hey if you want to stop every 5-10 minutes after all your shit's evaporated to refill... well in that case you're just a retard.

Some drag racers have nitrogen sprayers that sprey it onto I believe the intake to keep it cool. Although it may have been something else it was sprayed on. I can't remember the article exactly.

Wibbit:
Your engine is displaying the characteristics of too rich a mixture at low speed settings.If your engine get better as it warms up, its too lean. Watch your temperature for that.

For the rest of the thread:
maybe spraying nitrogen onto the intake, not into the intake.

Unless you have the intake supercooled, i do not think the air passing through actually has time to cool. To introduce cooling vanes or anything else will restrict airflow etc. besides, engine is heated up, intake valve is right where fuel burns. So how would one get around that?

There is another school of thought, where heat is desirable because it helps the fuel/air mixture atomize finer. I don't know about that, but I do know I would like my engine at designed operating temperature.

So unless you are doing a total reengineer, forget about it.

Edited for accuracy, excuse me

Well, if you wanted to keep your engine cool, and the engine bay cool, aong with power gains... You could always thermal coat yout pistons and combustion chambers. That would prevent heat loss and overall bay temp. And by conserving heat, you transfer all the power to the wheels instead of off the engine.

And you can do it at HOME!
