intake

[JICdrifter]

which company makes an aftermarket intake system for the y33

[Solini]

Not sure if you want to call it a system, but JWT makes an actual intake for the y33. I think you should be able to get one from Joe. Actually my friend might be willing to part with his, as he took it out.

[elwesso]

not sure whyd youd waste your time with a cone filter.... more dirt and more hot air... sounds like the kind of things that goes through ones head in order to think a cone filter is gonna do anything.

[Q45tech]

A common concept that engineers limit engine power to make owners suffer with reduced acceleration and gas mileage. That these same engineers hide power increase tricks so they can magically increase power and keep it from the general public and the companies customers.

That they would forgo a big bonus and extra vacation and awards from finding a little more power to beat the competition.

If you produce aftermarket parts you must lie [bend the truth] and manipulate power graphs otherwise no one would buy your products.

[maxnix]

One former board member did. It was a little peaky if I remember the graph he published correctly.

You may be able to find it in an archived post. Zinkie13 had to use it with his HID conversion. Was the member TGvince?

However, engineers have to consider other factors other than power. On a luxury car like a Q45 they also have to consider noise and packaging. I would bet that 90% of Q45 owners would not trade 5 HP for an interior resonance at 2500 RPM. Similarly, the engineers have to consider whether or not a particular intake is easy to install/interferes with any engine component.

Are you saying that all aftermarket companies are dishonest? That's a pretty blanket/bold statement.

[superuber]

Some of us have run our cone filters under or inside the bumper area.Lower noise and very cool air. Also water can be a factor if you drive in rain.As far as company's being dishonest, I thought only politicians lie?

[TXCumtrensh]

i have the stillen pop-charger on mine... I noticed no difference in power, gas mileage, or anything, other than sound... This is souly a Sound upgrade..

with the big venturi of the pop-charger, i do notice a "turbo spool" whistle at like 18% throttle though! its extremly noticable, and its extremly ear piercing.. And no theres no vaccum leak either (for those who would suggest it)

As far as there being an aftermarket intake (piping, couplers, MAF adapter) etc etc thats made for the Q45, Your out of luck, the only thing availible to us is the Maf adapter, and a cone filter...

[elwesso]

what im thinking about fabricating some day is a air dam that goes behind one half of the grille and then goes directly into the airbox... Talk about a COLD AIR intake, and you lose no filtering...

you gotta have a little bend in there somewhere, and a place for the water to sink down when driving in the rain... has to go down and back up.

[superuber]

Thats pretty much what I did except mine is right inside the lower air dam,off to the drivers side. But why bother others are saying after market parts make no increase in horse power.

[Falkdesigns]

Yeah, that's because every car is tuned for maximum power from the factory with no thought given to longevity or noise

I wonder why race cars don't just run closed factory style intakes, since open intakes don't make any more power, I mean, it's just noisy right?

Here, this is from SPEED yesterday, written by Autocar refering to Nissan's 350z ,

Quote »The obvious next move would be to do something with the induction system to help the engine to breathe better, and a lighter flywheel would make a big difference as well, helping to overcome the 3.5-liter V6’s rather lazy-revving nature.[/quote]I'm sure they don't know what their talking about either.

[superuber]

I guess i should throw out my Summit catalogs?Kinda makes the JWT and NICO ecu's pointless, right?

[Q45tech]

After market companies tend to publish the best graph they have and never all the graph or the worst one...............bending the truth or selective presentation of their results?Aftermarket companies pay dyno operators to test products........there is no independent publically funded test lab to qualify products.

Everyone who studies Statistics KNOWS that one needs 20+ samples to validate an assumption. Few take or show 20 dyno runs under identical conditions.

[Falkdesigns]

Again, that's why I think race cars across the globe should adopt factory style, closed intakes since they're just as efficient.

And again, I'm sure the guys that write for all the automotive magazines across the globe also have no idea what they're talking about.

And I suppose when I've seen dyno results of buddies cars, the operators were secretly paid off to make the results look good.

You're likely correct that an intake is not worth much on a Q. However, I've seen hundreds of dyno runs on dozens of mods for various year Mustangs and they almost always show an improvement. To second Falk-why don't super high perfromance cars have an airbox and several bends in the intake tract then??

[superuber]

Actually, I'm looking for Nascar to go with the stock chevy 3.5 litre v6Monte Carlo engine. That thing is out of sight, stock! And yes, i had a friend with an Impala. He dynoed it and I saw him hand the guy a two dollar bill and said make it look good. I mean the feds should really get involved here! It's anarchy!

[superuber]

Sorry guys, I got kinda carried away. We are sorta bored here at the shop today.

[elwesso]

Some of the posts here are absolutely ludacrous.... Itd be interesting to see how some of you would respond to these had someone else posted them....

1. We're not talking about race cars.... For engines that get rebuilt every few races, why run an air filter??? Only the big chunks of stuff will cause any damage... Last time I checked, most race cars like described dont drive for hours on the highway with rain and puddles.... Nor do they drive on gravel roads or anything like that....

2. You will technically gain HP from removing the air filter... So, why run an air filter at all???? I know a lot of people that run open MAF.... But, if your running an air filter, why bother using an air filter that isnt worth a damn. Go big or go home... Running no filter is better than wasting your money on a cone filter.... UNLOCK THE MAD TYTE HP BABY!

3. SPEED Channel is the ultimate source in professional unbiased automotive engineering...

4. NO one ever said that aftermarket products do nothing.... Must have been all that hot air again . It was stated that an aftermarket INTAKE would not significantly increase HP.... Somehow that means everything is meaningless??? Man, that stinks, i guess ill skip buying a couple of turbos for my Q....

Why people chose to trust sources that want to sell products as unbiased and trustworthy imformation is beyond me....

The point is, i know everyone here is smarter than that to make these sorts of crazy comments. Just think about how you would react if someone posted these things.

[qsiguy]

Well, people did get a little carried away but we all know Tech's point of view.......that the stock Q45 is perfection and we shouldn't modify it because anything we do will reduce performance. He's said that time after time. What's the fun in that? If nobody was experimenting with performance mods we wouldn't have much to talk about. It would get boring just telling each other to clean the MAF, how to change the oil, and put a new fuel pump in when it makes a buzzing sound.....

[Falkdesigns]

Amen brother.

Wes, if you've ever watched racing, the cars go off track all the time, in F1 for the past decade, gravel traps were used to slow down the cars that go off, and so often they get back on track and drag gravel all over it. Now I realize that they rebuild the engines after ever 2 races, but these are 20k rpm 2.4 v8 w/ 850 hp. LeMans cars race 24 hours and cover around 2500 miles in that time. Extreme abuse.

Now I'm not saying that you should run with no intake at all, I'm saying the factory intake is NOT designed for ultimate performance and air flow, it's designed to be quiet, clean and efficient. If you don't mind a bit of trade off in filtration capacity in exchange for a few HP (I know the best intake isn't getting more than 5 or 6 HP, if that), then go for it. Without people willing to try stuff out, we'd still be riding horses.

Personally, if there was a nice intake system for the Y33, I'd get it, but I don't just want a "pop charger" from Stillen, I want a complete system.

[elwesso]

you guys know how I stand on the subject but this was getting sorta out of hand....

I have no problem with people putting any sort of aftermarket intake thingy, but just be prepared they arent all theyre meant to be. You mention 5-7HP gain, that is probably not feelable really..... usually it takes at least 15HP to notice any sort of difference. Just need to know that first... One must be AWARE OF THE TRADEOFFS. Theres no free lunch....

I agree with what you are saying falk...

[Rex]

The real quesiton is if it will gain you 5, 7 or even 10 hp, where in the RPM range does it make these gains?

I spend much more of my time in the meat of the RPM range, though I see "the red line neighborhood" daily .

Also, if you're looking for more engine sound, then an intake may be just the thing for you??

[bullittandy]

Two of the first replies (from knowledable sources) to the question about a Y33 intake state that cone filters "are a waste of time" and that engineers design cars with no hidden power and that aftermarket companies "lie" about their products.

I think that these statements may be true about Q45's but they are not true of the aftermarket in general.

The answer to the question is that no one makes an intake for a Y33 and if they do it is unlikely to worth more than a few H/P on a Y33.

Thank you for making that point..... I was going to but i managed to forget... THANKS!

Remember we are solely speaking of intake mods that PRECEED the MAF assembly in this thread. We are also only discussing the 90-2006 Q45.

No fair to bring in other makes or models which may have more [excessive] pressure loses or less exotic designs.

Those with ODB2 scanners [96 and later] or Consults 90-95Q have an easy way to measure improvements in air flow [come to think of it those with a MAX HOLD VOM can measure MAF voltage directly at the MAF connector or inside at ecu.

Just drive the engine from a stop thru redline or let transmission shift and view the 4.200-4.500 peak reading from MAF [usually occurs around 6700 rpm].

At these high flows even 0.001 volts is significant, although the Consult only shows 0.01 increments so 4.02 is better than 4.01

[qsiguy]

As long as we're on the subject, have any of you seen the intake system that is in the front of the radiator/behing the bumper? I pulled out the entire thing and it's quite a complicated maze of tubing. I'll get it out and take a photo of it. I couldn't believe all the crazy tubes running off in various directions and the sheer bulk of it. Probably weighs 20 lbs. (that might be an exaggeration, I'll check.)

[Q45tech]

And it probably cost $500,000 -$1 million to design and create the tools to mass produce.............then the physical cost of manufacture.

Probably a $300 expense [EACH x 70,000 units] to create this work of art.

Spare no expense in making the engine produce maximal power and at the same time making sure the engine rings will have minimal wear at 300,000 miles.

Not the decontenting in the 97 and later Q when they need to save money.

With all due respect and appreciation. These are a bunch of qualifiers that you did not use earlier in this thread.

[Jesda]

Hey, did someone crank forward the date on this old thread?

Most Y33s dont have that many miles on them yet, with the exception of those owned by salespeople who live on the highway.

You can get an aftermarket intake, enjoy the sound for a few years, and yank it off when you sell the car with a dirt-worn engine to some poor sap at 170k.

[zinkie13]

I'll keep this short and simple. I have a custom intake. I know it worked for the amount of HP gained which was advertised. I did feel a difference when I installed it.
