Very interesting reading. Do note in there is no listing for any Genesis's.

will have my Weapon R in hand by end of day and will put into my Rspec sedan this weekend and will give you my thoughts on it in a few days.

Wow that write up is interesting, but I really don't trust it. I hate when I see intake companies claiming that there product can get much more air into the engine, the only way more air will enter the motor is if the factory was so restrictive that air couldn't flow through it at a reasonable speed. The intake can only aid in the flow of air it can't "force" it in. An engine will pull in as much air as it needs.

Air also always moves slower against the edges of the tube in the boundary layer, by adding the inner tube you add 2 more boundary layers to the system. If the air would move faster in the smaller cross sections then why wouldn't someone put a smaller tube to speed up the air?

And when it says the air is shielded I'm assuming they mean heat, but the air moves through intake tubes so fast that picking up any significant heat in the process is unlikely, at only 3000 rpm the intake air of a 4.6L motor is moving at 56.36mph that means its only in the 16 in long tube for .016 seconds.

But that's all just what I've gathered from my time working in the performance auto market, intakes definitely do have their advantages, looks, sound, a few hp here and there, but most the marketing things you see are just that, marketing. From my own perspective, I can't wait to have my own intake on my Genesis next week or so from R2C

Glassman I agree, but my experiences with intakes have all been great. I also have a 07 pontiac grand prix, supercharged. I would race my buddy in a 04 mustang gt and pull him a half a car to about 110 or so. I added an k and n aircharger intake system. Raced him the next day 4 times and pulled him a consistantly 3cars with that being the only additional mod. Different cars handle intakes differently, but that made a believer out of me..

I believe there are 2 or 3 other guys whom place orders for their weapon r intakes. Guys if you dont mind post your thoughts. I'm sure they will mirror mine. I'm just glad we have something that add's a little more excitment to the genny. Note: I noticed the first few pulls I did with the esc on the engine bogged a little. After I drove for some time and allowed the engine to get use to the new air flow. Throttle response was amazing, even when normal driving the car responds so much better. I was a little surprised that no one on here had installed the weapon r before now..

Cooler air flow is beneficial for all engines but I think it makes a greater difference when forced induction is involved (particularly if there is no intercooler).

received my weapon R yesterday and it came with a ram air addition as well. have any of you installed this along with your air intake. and those who have installed how long does it take to install, doesn't look that difficult just by looking at what comes off car and the addition of the intake.

Anyone dyno this yet? This is great bling, but does it perform too?

I think this subject has been covered extensively elsewhere, without ECU tune, the gains if any are minimal, which maybe similar to removing the air intake door/restricter/flapper and in some cases some have noted a small negative impact.

So for now, I would suggest that other than the 'bling' factor and some extra grunt the proformance gains, if any, are within the margin of error of any given Dyno setup, ambient/engine tempreture the person who is performing the test etc (upto 1.5%) ...

Not entirely true. Take a look at this link. The local guys here Abel Racing dyno tested a 5.0 RSpec with a setup almost exactly like this. They recorded 15whp (wheel horsepower, don't know the engine horsepower gains but I'd rather see it at the wheels anyways ) gains over the factory air box with a K&N filter drop in. This is more like a ~4.3% gain in horsepower to the wheels. The evidence, from what I have seen, supports that the factory air box is restrictive and replacing/modifying it can release some additional horsepower.

While this isn't a significant gain, it is a gain none-the-less, not a loss in horsepower. And with the almost complete lack in after market products and modifications for this vehicle, it might be worth it to some like me. I want those extra ponies!

Well got the intake installed and I am real happy with the aggressive sound when at full throttle. Seems to have a little more umph but that is just a seat of the pants test. Would like to hear some dyno results with this intake. But at least now with the aggressive sound it sounds more like a muscle car.

flynblind, welcome back. Thank you for all your contribution to this forum and for making my point for me...

In the link you have provided someone announces "354" with the CAI in place! However here is another video that confirms that the base line (stock) should be 365 HP:

https://www.youtube.com/watch?v=Ld-pTsd3EOM&feature=youtu.be

Inside line agrees as well with that number (ok 364 close enough):

http://www.edmunds.com/car-reviews/track-tests/2012-hyundai-genesis-50-r-spec-dyno-tested.html

So where does that leave us?

1 - Abel Racing dyno is a tad wacked.
2 - The other two Dynos are way off (although interesting, since they both agree on the same number).
3 - The CAI setup caused 10 WHP loss!!!

I might be reading something wrong, but if they truly added 15 hp I would expect the number to be around 380WHP ..

I would suggest that without resenting the ECUs there is HP loss, even then I believe any HP gains noted, can easily be replicated by weakening the air box magnet/removing the air restrictor door assembly completely....

But there is more, even resetting the ECU has limits because the safe programming utilized by Hyundai! This may only be overcome by an ECU crack/tune...

Please do not get me wrong, I love this upgrade but purely from the looks as well as the sound/extra grunt and I might install the Weapon-R, even though some HPs might be scarified in the process...

Of course each to his own... After all, this forum is all about sharing ideas, conclusions and learning from each other...

You also need to account for each dyno, I read that a local dyno reads well below other dyno's I do not know what causes that though. I think the only real way to find out is run with stock and then on the same dyno run with new, after giving the car time to cool down of course.

 

[flynblind]

Thanks for the warm welcome back!

I always enjoy talking about the Genesis because there just isn't that many out there!

Abel Racing did state that there was a 15whp gain over the standard air box with the K&N drop in filter. While they may not have their dyno calibrated perfectly, it does mean that they did experience a gain in horsepower.

I would assume that if they got 354whp and experienced a 15whp gain, then their original dyno test was 339whp. That doesn't match the 364whp that Edmunds recorded so their equipment could have been out of calibration. Or the car they used could have been "used" versus a new car that Edmunds used. But, it doesn't mean you can apply Edmunds' baseline test to Abel's intake test.

Lots of factors come in to play here. But, there is some evidence (even if not within expectations) that there is a gain from an intake such as this.

I am definitely interested in getting a SRI/CAI depending on design and performance after I get my exhaust system changed.

 

[2011 Genesis 4.6]

I just commented on another thread I removed the flapper, and pulled the foam filter out, and removed 2 of the resonators in the stock intake system, the 3rd appears to be molded in and not removable. I blocked off the holes for the resonators.
With those mods and my custom exhaust I feel it spins 255/45/18s almost too well. I may have to go to 275/40/18s for the rear.

 

[20124.6]

Anyone put on the ram air kit that comes with it? I haven't yet and wanted to know if worth it

 

[JBoogie]

has anyone had a problem with the metal shield being in the way of getting the filter to slide on? I hope Im doing something wrong because i cant get the filter on with the shield installed...

What did u use to block off those other openings?

Well in the pic you can see that the left opening has an extra oil filler cap I had in the garage placed in it and clamped down.
For the other side the cap for a bottle of windshield cleaner. Those were all I could find in the garage when I was looking, but anything that fits and will not leak air will work.

That's kinda cool since the CAI i received was a total POS!! The fitment was terrible. The pipe wouldn't align with the MAF, the screw that was to go into the manifold wouldn't align if the pipe to the manifold was installed. The shield would rub against my engine and the pipe would have the filter pointing up (where the hot air would be) instead of down (where the cooler air would be coming in). Cant wait to sent this POS back to!

 

[blkgenRspec]

Jboogie, you have a 5.0 right? I didnt have any fitmit issues with the shield or the filter.. can you take a pic of what your experiencing? It did take me a few minuntes to figure out which way the pipe went.. Look at the pics I posted. If that helps..
