After a long time searching, I have decided to buy the Injen and use it as a short ram for my Tc (we get quite a bit of water on the road in Montana). I need to know if this will have any impact on my fuel economy?

What about the full CAI?

Thank you for your info/help

 

shouldn't affect fuel economy that much by itself...If anything, may increase your mpg. Unless your driving like a race car driver now that u got an intake ;} But under normal drivin conditions should improve fuel economy a tad...(i don't have it {yet} but I know enough about air intake/fuel economy tech to tell u that for sure.

 

It should help I know it helped me about 1 to 2 mpg. When i had my Civic yes i had a Civic, it help it as well. The car will also run smoother cause the car can finally breath without restriction.

 

It won't effect mileage in a negative way at all....

Unless you plan on driving through 2 foot lakes... Go CAI... the engine bay is too hot for SRI's...

I like in Oregon... It rains insanely here... and no problems...

 

It is true that engine bays get hot...but actually, when your car is moving at speed, a lot of cold rushing air is coming up thru the bay from the undercarriage and also thru the grill. Dont get me wrong, a CAI will make more power, especially on a dyno where the car is still so the engine bay is hot but the undercarriage (where the filter head is located) is cooler, making for lower intake temps and producing power gains. But driving on the road, the difference is very small and IMO not worth the risk of hydrolocking your motor. ALso the long piping of CAI's means the air has to travel further to reach the manifold, reducing the pressure and density of the air and resulting in a loss of low-mid range torque.

IMO CAI's became popular based more on the concept/technology than actual performance enhancement.

 

if u want a CAI u could always get the air bypass valve from AEM that will reduce the risk oh hydrolock.....

 

yeah thats the key..."reduce", its still possible tho. But in all seriousness, as long as your vigilant and a somewhat intelligent person and smart driver, you probably won't have a problem....but I just don't see enough of a gain to outweigh the minimal risk. .02

 

brilliant post. nuff said.

 

thanks bud...couldn't agree more! ;) heh heh

 

You will not have to worry about the tC hydrolocking w/ the INJEN CAI. The filter sits high enuff that if it did hydrolock, you would have to be sitting, in the driver's seat, with water in the interior.

As far as mpg, mine dropped slightly becaue I developed a lead right foot. I wanted to hear the air beng sucked into the intake. On my xB I still get 30+mpg going at highway speeds of around 75 mph.

 

I'm not sure i understand what yur getting at...but I think your saying the only way you could hydrolock YOUR MOTOR is if your car is half submerged and water was fillin up the interior???? Ah actually all that would have to happen is to drive thru a deep puddle or any water body that may cause a splash of water to go up thru the undercarriage and get sucked thru the filter.

 

Its going to take more than just a deep puddle to hydrolock an engine.

I didn't run my inner plastci fenders for a while, and during last year's rainy season I didn't hydrolock. I did it to prove a point to a few people who had the same concerns.

Better yet, how about starting a thread asking who has hydrolocked their Scions? Under any condition.

 

Here's the thread to see how many have hydrolocked their Scions.

i feel the same way.

 

People still talk about hydrolocking?

You won't hydrolock any car, with any CAI so long as conditions are right as to being able to drive. You can't drive through 8ft deep water, if you can, wow.

Seriously newbies, i love some of your posts. It gives me short lived free entertainment. (no offense, of course)

i have to agree with squirrel... hydrolocking is practically impossible with how high the filter sits...the filter will suck in water only if it's submerged... and that means your car would have to be half-way submerged for that to happen. even if the filter got wet itself, that this not even close enough to cause any risk of hydrolocking. big splash from a puddle or not.

people need to stop worrying so much.. sheesh.

 

Newbie?? who u talkin about? YOU're 19! haha...You obviously didn't see my post about my buddy who hydrolocked the b16 in his civic the day he picked it up from the shop! THe filter head does not have to be submerged in water...its like a vaccuum...it can suck water right into your intake manifold.. I don't care how many scion owners its happened to...I don't know Exactly where the filter head is but its still a risk, and the bottom line is the hp gains aren't worth it in the eyes of any professional (whos not trying to SELL u one!) I really don't care what u 19 year olds think...it happens more than u know! Maybe not in Cali...but def here in philly!!!

BTW IF u happen to seize up your motor cuz u hydrolocked it due to your CAI....a new motor ain't covered under your warranty!!! SO yeah, I'd worry a little if I had one.

Ps...Duh, even cars with stock air intakes can hydrolock, happens everytime theres a mild flood and some moron tries to drive thru a deep puddle!

CAI's sound great in theory and on paper, but they're just a passing fad...in 5 years everyone will have Short rams

 

And you are 24, congrats on reading my age. Age rarely has anything to do knowledge as far as forums go. Since 17 i've been modding cars, not too long. But my knowledge goes back further than that. I started learning about motors and different cars at age 13. Started working on various small projects, and helping with projects since around 15 or 16. So, yes, compared to a lot of people on here, i have more experience. Setting that aside.

Wow, you know one person to hydrolock a car. Its actually very difficult to hydrolock a car, i'm sure its more prone to happen depending on where you live and what kind of weather typically occurs but, yeah. The water has to be pretty deep for there to be enough water to cause hydrolocking. Just a little spray of water while driving getting on the filter will not cause a hydrolock, and with typical rain and typical driving, the filter will never even see water except when you take it off and clean it. It doesn't matter what car you have, intakes are intakes. I used to own a 97 gsr, so what?

Forgot to add:

If you actually read my post you quoted earlier, you will notice i said its near impossible to hyrdrolock a car under conditions available for driving. A mild flood highly consitutes as driving conditions. Anyone that would drive during any kind of flooded area is a retard. Puddles won't cause hydrolocking, even "deep" ones that exceed 6'' (which, i might add is rare for a puddle to be that deep. not talking about side of the road puddles, anyone driving that close to standing water is also a retard. but, even that wouldn't cause hydrolocking) so long as they have the walls to protect, anyone running without them is asking for lots of dirt and water spots in their bay.

So, read my post before you start bringing my age. Thanks.
