This discussion was started in a different thread, but I started to think about it more this past weekend.

The question is really towards the people who did that their resonator off, but didn't feel there was any gain.

If you did take your resonator off and didn't feel any difference, what type of tranny to you have?

I ask for a specific reason...

 

I did the ECU reset. I notice that below 2700 rpm there seems to be less pickup. However, at high rpms there seems to be a bit more power.

But then, it could be just the noise.

The question still is, "What type of transmission (6MT, 5AT) is on your TSX?"

 

My sig didn't come up. Sorry. Fixed.

 

See what I'm thinking is that of those people who don't feel much difference if any, that the Auto's torque converter is hiding it or negating it. Basically, of those who did feel a difference were probably driving manual transmissions.

Interesting thought eh? Kinda makes a CAI for an Auto useless if my assumption is correct.

Basically, the CAI will help the overall HP and high end torque, but it won't have a difference in feel b/c the torque converter is going to hide it.

 

i don't see how a tq converter can hide anything. If anything it would help as the slipping allows one to get into a higher rpm where you would see more gains from the intake. If anything I think the issue is that with the 5at cruising on the freeway you are turning 2400-2700 rpms. Any loss of torque in that range is going to be very noticeable. That's why i'm still debating on if a cai is right for me. The extra horses would be great but the loss of toruqe in freeway cruising range would suck.

 

No noticable gains (other than noise gains) w/6 speed.

 

I would disagree, but that's my opinion. It isn't so much that it hides (that was just an easy way to say it) as much as I think it makes what little gains there would be with a CAI more linear and less noticeable (mind you that a CAI will require the removal of the resonator anyway).

 

I'm glad you posted. It is important to see that if someone hasn't noticed anything in both transmission configs that it gets compared to those who do get the CAI whenever that happens.

Also, I'm thinking you and I are the only people who have painted their fog light plates. It is not so noticeable on my CG, but very complimentary on you AB. I've seen some people with the white and really wish they would paint their fog light plates. It would looks sooo good.

 

I know you probly already know this but Injen has already dynoed there CAI with an Auto TSX and found 11HP. Wheather that can actually be felt is another story

 

+11hp at 7000rpm would be barely noticeable, IMO.

 

This and sauceman's response are the core of what I'm trying to get at.

Mostly what I want to try to prove, without a dyno at my disposal, is if my simple and inexpensive mod generates even 50% of the horsepower claimed by a product you have to buy.

What fun that would be!!!! I could help rid the world (at least in terms of the TSX community) of useless marketing ploys to take our money when we are bright enough to solve the problem ourselves....


Sorry for the ranting, but seriously. What fun it would be to not have to spend money on a good mod.

 

Hmmmm, maybe it is all a marketing ploy, but would'nt someone have figured out by now that the same or similar gains can be obtained without the need to spend $250+ on a CAI?

I'm thinking someone out there must have dynoed a Injen or AEM CAI against a home made one and posted results?

I mean why would these companies spend thousands or hundreds of thousands on a product that can be duplicated by anyone with some creativity? The risk is too big and the true answer too easy to find out.

 

if i had access to a dyno I would totally make a bunch of custom intakes and see what works best.... personally I would prefer a cai that gave good low end/midrange gains. That should be accomplishable by making sure the intake has a cold air source; making sure the tube is relatively narrow and long to ensure good air velocity, and using a design that steps down pipe diamater from inlet to throttle body to further increase flow speeds. Also putting the inlet on the front of the car...like where the foglight cover is might make an improvement.

 

tinkySD u have access to many dynos in ur San diego u can go to pann autosport off of clairmont, engineuity in national city, AEBS in miramar and a few more hehehe if u need directions ask hehe

 

Vtec.net has had this article up for awhile now, which includes a dyno for a 6spd TSX w/o the resonator. According to them, they saw a gain of 5 hp.

I think it is interesting that moda's 50% prediction turns out to be true!

 

Thanks for posting Thrawn. I'm still running without my resonator and loving it. I'm not against CAIs by any means, but it is interesting that I didn't have to spend a dime to make potentially 5 more horsepower.

 

bringing this one back from the dead. Check out this link. If you can't access it i'll save the pictures and host. I might do something like that as I have some old mandred bend piping laying around.

Similar.

If you go to that extreme, make your own CAI and add a K&N cone filter. You just made a CAI.

I'd like to cut out the chin vents as well, but I'd prefer to do it on a drill press. I also want to verify that I would not create a huge back pressure in the resonator cavity and start to bend the wheel well trim outwards.

 

I did make one on my previous car which is why i have leftover tubing sitting around. I think the real draw with that kind of setup is the stock airbox/plastic tubing to avoid any types of warranty hastles. I'm betting the bestway to pull that off is to run some metal conduit(dryer type stuff) from the bottom of the stock airbox directly to the chin vent. Cut out part of the chin vent so that air flows directly into the intake. Would be a pretty sweet setup

 

hmmmm what kidn of metal tubing would be ideal for that sort of setup? Something light weight..possibly flexible but with a smooth interior.

 

if you pipe it to the front vent, you increase your chance of sucking up water, small rodents, and broken crack vials...

If you want to custom bend something, hook up with a place that make custom exhaust pipes. They can bend large radius tubing without a problem.

 

using a 180 degree bent mandrel bent tube i made my own cai. ill take some pictures if you guys want to see

 

Pictures please!

 

here are the pics

finally took off my bumper b/c i am installing hids in my fog lights.

 

So you have to remove your front bumper anytime you need to clean the filter? Why not just keep the stock airbox, drop in a K&N and put an intake tube into the resonator cavity w/o the res? Since the gains are only a few HP with the CAI, the difference between that and a K&N and no res couldn't be noticed - except for the sound.

 

yes i went without the stock airbox for the sound. and also taking off the bumper is no hard work and you dont need to clean the filter too often

 

on mine you dont need to remove the bumper just th elining under the car...my design is almost identical to the injen..but half the cost muahahaha

 

I would also agree that you don't have to take off the bumper to clean the cone. I've seen the post were someone didn't take off the bumper to put on their CAI, which I knew you wouldn't have to, but I bet my install involved a lot less knuckle bleeding and monkey wrenching around inside the cavity trying to feel for the bolts.

I also plan to do the K&N drop in when it comes time to replace the filter.

 

yea, it is true that CAI doesnt do good at 2500~3000 rpms for AT.
but regardless of the pros and cons of the CAI, CAI makes driving more fun^^...i said this prob cuz i am a kid

by the way, is AEM gona make CAI for TSX as they did for RSX and TL?...any inside news?
