How many times did I have to tell you not to drive in swamp waters... hydrolocked? what? HOW!? Im just messin with 'ya...

So, I had a camry once, with an anjen intake on it... didnt void any warranty... anyway... here are the simple rules... The reason you have an airBOX is so that built up pressure gives you more power in the low end... the open element filters get better airflow when youre at speed...etc.
What I would do is install a K&N air filter on the stock airbox and tube... and then seal it in... its a little of both worlds... flame me if I didnt make sense

 

at racingsolutions.. they say the weapon r has a "12.91HP " gain. is that a little far fetched or is it just me?

 

SCC did a dyno run of the AEM CAI w/ the TRD exhaust. But there is a discrepancy in their results. In the body of the article, they state that the CAI and exhaust put down 141 whp and 152 wtq. However, in the result summary, they show the results as 152whp and 141 wtq. My guess would be that the latter is correct, since intakes, particularly CAIs, tend to sacrifice low-end power for more power up top.

Those gains are from the initial dyno run of the prototype. A follow up dyno of the intake resulted in only a 6whp gain. However, they have since made further changes (to correct issues with CELs), and no dyno's have been released yet of that final version. I believe lvnurs will be doing another dyno of the final design, along w/ CC's complete exhaust kit w/ high-flow cat, soon.

That dyno is for the xB. The tC dyno is here, and shows a 6hp gain. However, heat soak appears to be a particularly nasty problem w/ the K&N CAI for the tC, according to feedback from people on this forum.

 

Well, then thats good new for me then!

 

hey there people...ok i got the K&N CAI and havent put it on yet, I am waiting for the spring...anyway, what is heat soak?...if anyone has an answer let me know...thanks people

 

As you know, the inside of the engine bay gets really hot, some areas more then others. Depending on the position of an intake (and the material its made from), its piping may begin to absorb a lot of the ambient heat, more then it dissipates (given the weather conditions) causing the temperature of the air being pulled in through the intake to rise. The hotter air gets the less dense it gets, therefore the volumetric efficiency in each power stroke is reduced, causing a loss in power. On colder days/nights, it wont be a problem, but on warmer days it can pose a big issue. Wrapping the tubing in heat insulating wrap (you can find it on eBay cheap) reportedly helps alleviate the problem, but even then the heat will eventually seep through. There are cold air boxes available for some of the short ram intakes, that attempt to shield the intake cone from the ambient heat. Alternatively, you could wait for an intake that is not made out of metal, such as Volant's. Theirs is made from polyethylene which will not be as prone to heat as a metal intake. I contacted Volant a few weeks ago regarding an intake for the tC. They said that they are currently looking for a tC to test fit one on. FYI, Volant is located in Rancho Cucamonga, CA, if anyone is in that area, you might want to consider contacting them. Here's their website, I heard about them from "Two Guy's Garage" on SpeedVision.

 

i have been reading about all of this for a while now and there are so many replies w/ positive/negative comments that I do not know what to pick. K&N was one choice I was thinking about.... can someone give me a good reason why not to get it?? OR - how about the one that you can get from the factory??? Please let me know cause I ordered my scion and I have a week to think about what I want done to it.

 

I would suggest you save your money and wait for more dyno results from Weapon R, Injen, AEM, and K&N. It's not like you have to have it installed as soon as your car gets in.

 

wow man....that is some good info...thanks alot man...i think i might try to get sum insulation...but that wont till be the spring...anyway, thanks for the help man..peace

 

what should i do guys? I am gonna get a catback and need an intake that will match it. ... what should i get? I know K&N has always been a good company for many years.... is there something better?

 

I hear that the K&N exhaust (or was it the intake?) sacrifices low end tq.

 

you heard that the k&N intake sacrifices low end torque because that is what i have heard also but I dont know if thats fact. I just might spend the few extra bucks and have scion put on the intake they they say to put on.... i forget the name of it. Does anybody have any view on me doing this?

 

That's the Borla exhaust. I don't recomend that sense it's just an axle-back. Go for the full cat-back if you have the money.

 

that's hilarious that the two of you are going on and not really paying attention. one guy's talking intakes and the other is talking about exhausts!
just read this post, it answers your questions, bro.

 

Wups . I guess I got mixed up lol.

 

i wonder if heat soak is the problem, or if it's the heated TB. doesn't the tc have a heated TB?

 

i posted this elsewhere but i dont even know i cant find the AEM one anywhere but here http://scionsport.com/store/product_...dd8737d5d636fc
so i dont know if its out or not anyone know?

 

it's not out yet, but people are taking preorders it looks like

 

I think I am going to get the Injen today. Can someone stand up and give me reason why I shouldnt? I looked at a dyno of the K&N and it showed a very small amount of torque decrease at a low rpm but I cant give you the exact numbers. Truthfully, I really wanted to go w/ the K&N still because I know they have always made good products.

 

How's the dyno on the Injen???

Supposedly the Dyno report on the Weapon R (which is NOT a CAI) is around 6 hp, which is the SAME as the K&N CAI. and is cheaper

How much are you getting the Injen one for?
