Paying $500 for an induction hose and intake were worth it to me, just to clean up the god awful mess that the stock airbox and induction hose with sound generator were.

Still haven't had a chance to dyno it to see if Mishimoto's claims of +16HP over stock are accurate. But I can feel a difference, that's for certain.

I was about to look up which intake to get... just to get the most out of the engine for autocross. Seems like everyone suggests the drop-in... which I already have.

That is one solid reason to change to a different intake as it certainly does clean it up.
The claim of +/- 16 or so hp improvement is fairly standard to all the different intake suppliers but the independent dyno numbers I have ever seen never seem to come close to that (not without a tune to go along with the intake at any rate).
What they do actually help with is slightly improved throttle control and smooth out the 4000 dip a hair which can be a noticeable difference.

Don't forget stickers add hp too.

No where in that thread is the dyno doug at topspeed did of his factory manifold that was decatted that made more hp than all those did. Search his sn topspeed. He beat all of that with the factory header with the cat cut out of it and a stock airbox.

But hey this community is slowly becoming all about looks and Internet engineering anyway.

Do you mean this thread: http://www.ft86club.com/forums/showthread.php?t=57270

Seems he didn't have just a decatted header...he had an e85 tune and other mods.

CAI is pointless unless you are turbo. If you're just dying to dress it up under the hood, it's your money. If you want to do something that MAY be helping, get a 50 dollar (or less) drop in panel filter and call it a day.

I pretty much agree with this statement with the exception of the GrimmSpeed intake.

There was so much R&D put into that unit and it has actually shown gains that are worth while of spending the money on. 15+whp with just the intake and tune isn't bad.

Otherwise, I would definitely just spend the $50ish and get a drop in filter and call it a day.

Very important to understand!^^

Sooo, 14hp from the tune then?

Obviously...

No. It was like 10whp with the intake and no tune. Then another 5-7 or something with the tune.

I've had the Greddy intake for over 2 years and I like it. Before I bought it, I already had the Greddy Evo3 exhaust. I tried the K&N for the hell of it while waiting for the Greddy intake on preorder. The K&N was a slight improvement over stock. The K&N oiled filter in hot climates is a recipe for MAF sensor contamination. I went through that with my Tacoma 4x4 and had to buy a new sensor. But the Greddy dry filter has been better than the K&N drop in. With the GReddy Intake, the car is defitinitely more responsive and sounds a whole lot better than stock or K&N with sound tube. I did remove the intake snorkel when I installed the intake. I connected the sound tube but I didn't drill a hole in the Greddy intake. I left the sound tube installed for future smog checks when I have to switch back to stock for inspection.
The Greddy intake matched with the Greddy Evo3 exhaust and the car breathes and responds way better than stock or with K&N drop in.

I would never ever use the word "obviously here"!
Next thing you know some dude will be posting "got the intake you said and only got 10 hp out of it. I read that it should be 15. Should I take it back/get a different one/beat the crap out of the guy that sold it to me/is there something wrong with my car/etc"

I have the TRD intake. If you want it for performance then don't waste your time cause I don't believe it will give you any. If you want to clean up the bay, get rid of the damn sound tube, and stay with Toyota parts then I say go for it.


PS: I LOL at getting 10 WHP from the Grimspeed intake.

Damn I thought Victoria Australia had bad EPA rules. You Cali guys can actually get fined for a sealed aftermarket intake?

I have the aFe Takeda (Same as the Greddy), but I drilled a hole for the soundtube. Also removed the snorkel, cos the intructions explicitly recommended it.

Your best bang is a K&N drop-in filter replacement. I believe intakes are a waste of money for this car unless you are doing an NA tuned setup or are doing it purely for aesthetic reasons. The stock airbox has been proven to be pretty efficient for what it is. I'll stick to that until I turbo one day.

If I have to convince myself that a mod does anything, then it isn't worth it to me. I know I'm not capable of feeling a 5-10hp difference in a car. Maybe everyone else's butt dynos are just better calibrated.

You'd probably need Niki Lauda's butt to detect a 5-10hp difference on a 200HP car.

Honest question. How on earth could that mess be efficient?

Airbox volume is key. Also the oem box takes into account resonance. Checkout some Superbike airboxes. Like the r1, s1000rr, ducati Panagale.

Just seemed like a waste between the extra tube with the sound generator. And as I'm pulling out all the stock components, noticing how restrictive the air diversion channel seemed compared to the new plate that I installed.

Now you guys make me want to take the intake out, dyno it, put the aftermarket back in and dyno it. Should a intake companies dyno results be thrown out the window? And if so, how are they able to advertise those numbers without being in trouble for fraud?

No doubt there would be some improvement and I don't think anybody is saying the stock one is perfect. More just a matter of for a stock set up they are pretty good compared to many other vehicles set ups. The original question was what is the best "bang for the buck" and in that context the drop in filters probably are.

If you are really ambitious and want to try and find them, there are already dyno comparisons between stock and aftermarket intakes on here someplace. Been a while since I saw it but seem to recall almost none made the numbers that the manufactures claim. Now add a tune on top and ya they made it. It isn't all that hard to push any sort of measurements up to what you want if you know how to tweak the system just the right way. Maybe they did 20 tests at 2 but then got one at 10 and said "ahhh there we go the max is 10 we don't need to discuss the other 20".

How many products of any type live up to the manufacture's claims? If they all did what they say they will there would be no obesity because a couple of special shakes would keep the weight off, every car would get the top mileage listed all the time and the average size of a dong would be 12 inch's!
How do they avoid fraud? Simple as putting a small print disclaimer on the product literature that says "results may vary". You will also frequently see statements such as "up to XXX" which of course can be argued that if you even have any increase at all you have met what they claimed.

The whole thing is that if you are happy with what you have and it does the job for you then why bother trying to prove that everything else is no good? No matter what you have somebody someplace is going to think theirs is better no matter what numbers you throw at them.

Very efficient without the cat.

I did a K&N drop in (might replace it with one that doesn't need to be oiled soon) and the Perrin intake tube/sound tube delete. Cleans up under the hood a bit and gives better air flow. Like a lot of others have said so far, the drop in is all you want/need unless going FI.
:cheers:

its all in the tune boys

You resurrected a 2 year old thread for that gem of wisdom?

I like how you always call ppl out because they didn't use the search feature to find "2 year old" threads to find information... Now you are calling me out for using the search feature, since gee idk, maybe im looking to install a CAI..

Contradiction, pass it on.

The thing is your resurrection contained no new information (useful or otherwise), humor or point of interest.

So in a similar vein I give you

Attachment 146454

Please indicate one place I told somebody to search. Did you resurrect to ask a question? Did saying it is all in the tune help you make up your mind what intake to go with?
Anybody is free to resurrect whatever they want for what ever reason they want I just found it funny that a 2 year old thread came back with info that was already said several times.

The motor doesn't require more air than what the stock intake can provide.

I didn't realize how old this thread is. Sorry

Eh... research the grimmspeed development thread

Actually, yes... You helped me out, thanks cuz

Thanks man :barf:

U can research grimmspeed, mishimoto, perrin etc. A proper tune will all but negate any gains from a quality aftermarket intake. They might show some gains on the cheesy stock tune but those gains wont stack on a good tune.

Eh....research the grimmspeed development thread.

No thx, im running a velocity stack with a wad of foam in it. Butt dyno says 20 more hp.

:iono: I guess I like science and proven testing. If nothing else it is a good read, and shows I think 60-70 different combinations of parts along with air fuel ratios, tuned / untuned results and more hard data. It has been awhile but I think 100 miles or so of dyno tests.

Wad of foam and a velocity stack? Do you also have the highest na hp frs? :popcorn:

No doubt they did their homework and their products are high quality.
