Is this part out yet for the TC? And if not any info on when it will be?

 

I don't believe its a TRD/AEM item, just an AEM item. Also, the part is out its just in limited supply right now is what my understanding is. I'm just going to wait for a WAI because I think they look better than a tube that goes down to the ground.

 

WAI...?

 

Warm Air Intake, aka Short Ram Intake.

 

Exactly, stays in the engine bay, doesn't pull in cold air, just frees up restriction more or less.

 

ah i c... never heard it called that before ;)

yea, on the RSX-S the Injen "WAI" performs better than AEM CAI or even Inejn's CAI.

 

I haven't heard it called that before either, it's normally called a short ram. And no RSX short ram performs better than a CAI. They are sometimes less restrictive, but it only takes a few minutes of normal driving for heat soak to completely negate any gains from a short ram. They can also make you bog pretty bad off the line if you've been sitting at a light for a while. Dyno numbers are meaningless since they usually have the hood open with a fan blowing on the engine compartment, so you have to use 1/4 times to get a true picture.

I'm a former RSX-S owner who has done extremely **** research on RSX mods, so I'm not just making this up. The fastest NA RSX's out there wouldn't even consider putting a short ram in their car, and they have the times to back it up.

Oh and I didn't register just to reply to this :D I'm considering getting a tC.

 

I find this a little hard to believe - if the Short Ram outperformed the CAI from the same manufacturer, why would they even make a CAI? Just to increase the price and chance of hydrolocking your engine? I don't know what kind of performance enthusiast would buy a more expensive, less effective, heavier part. I know that K&N will not make a CAI if the SR outperforms it in the same application.

 

so lets say injen makes an intake for a car and they only make the short ram... is it safe to say that the CAI setup is either outperformed by the shortram or is user friendly(water)

 

Short ram/WAI same thing. Anyways, i think the intake provides more of a look cool effect than actual performance effect. If you notice all the fastest cars, they don't bother talking about intakes.

 

You can't always go by dyno numbers for numerous reasons. CAi or WAI your not gonna see a difference in performance, maybe 1-2 whp if that.

 

I know this is the case with K&N - I think it is pretty safe to assume that if a manufacturer makes a SR intake but nothing else, it is because there is either no reason to make a CAI or it just isn't justified. As for the water friendliness, there are ways around it with a CAI, so I would assume the water issue isn't stopping anyone from making them.

 

listen, i only made that RSX/Injen comment because the four friends that i know that have RSX-Ss all told me the same thing. remember this is JUST FOR THE RSX-S... Since i always heard CAIs beating short rams, this was a surprise for me as well but they all confirmed it. they've done their research as well so that's where i'm coming from.

the heat doesn't well up under there as much as you think... maybe from a stop light the heat will build up but since the pipe is metal, it cools immediately after driving once the airflow comes in. same goes for AEM CAIs since their pipes are metal... this was once an argument between AEM CAIs (metal) versus Iceman CAIs (plastic)the AEM design isn't always the best and the more angles in the pipe CAIs usually have may actually have a negative effect analgous to the reason why catback exhausts try to have the least amount of bends as possible, sometimes resulting in an angled muffler install. if you don't know what i mean, this is a supra from someone i know... look at the muffler. the Injen also has a heatshield which may help.

as far as CAIs go, obviously they most likely perform better because of the marginally cooler air they pull in... if i had a choice between short ram or CAI, i'd probably go with CAI. however, that doesn't mean that they rule and if you can't trust dyno numbers, then what are you gonig to trust? your butt? your gut feeling? what the manufacturer says?

 

I know that in an RSX-S, a CAI can mean running a 14.5 instead of a 14.8. Depending on the car, they can give quite a bit more than 1 or 2 horsepower, more like 8-12 to the wheels. They're worth the money, IMO. Dynos are also more accurate with CAI's, because of their position below the engine. Of course you would want to take the manufacturer's dyno results with a grain of salt.

 

Trust 1/4 mile times and tuners who actually race their cars.

And yes, in my experience, your butt dyno can feel a 10 horsepower difference pretty easily :D

 

but the butt dyno can't feel just a CAI or short ram install, nor does just a CAI or short ram give ~10hp. henceforth, dyno results are key.

 

Oh but it can feel a CAI by itself, because they do give ~10hp by themselves.

Gains from mods aren't cumulative, so I/H/E which by themselves might total 25hp will not actually give you 25hp when combined. But a CAI by itself will give you ~10 (depending on the car of course), and you can feel it. A short ram you probably won't feel, although you might think you do, since they can be obnoxiously loud.

Here's a great example dyno of an RSX-S gaining about 8-9 from a CAI with other mods. If they had done the CAI before Hondata, you would have seen a few more horsepower out of it, and a little less from the Hondata. This test was done by Hondata, hence their reason for putting the Hondata on first - it shows the most gain that way. Clever!

 

has anyone else heard of an intake giving 10hp???

what i want to clarify, is that i'm sure you'll be able to FEEL 10hp, no doubt... just saying that i've NEVER heard of an intake itself giving 10hp. my question isn't whether or not you can FEEL 10hp, it's that an intake would give that much. i'll stand corrected if someone confirms that an intake can give that much.

 

While we're awaiting answers from others, you might want to think about it this way - an intake will give more hp depending on how restrictive the stock intake is. On cars that are designed more for grocery getting than performance, they will be extremely restrictive to reduce noise. For example, you can get 1-2 hp out of an RSX-S just by cutting off the fins inside the stock airbox. A CAI on an S2000 doesn't give you as much, since the stock intake is already designed to flow more air than the grocery getter's.

 

Actually there is a part out from the toyota dealerships. They have an option to put int he AEM cold air intake im not sure about the price, but i think it's around $320. But that is avaliable along with many other TRD products that toyota is offering for the Scion tC. I hope this helps you.
