AVO Turbo Kit Owners Topic

[nataku]

With my open filter I can hear intake hiss like crazy but the turbo itself doesn't really make much noise. Nothing like GT3xxx jet turbine noises.

I hear the turbo on the AVO kit when I have an aftermarket intake on the car. I put a stock airbox with a panel filter on and I don't hear the turbo much anymore. So yes, to answer your question, the stock airbox does muffle the sound of the turbo.

The Perrin CAI on the other hand, being a long tube intake, doesn't muffle the sound, but has a different resonance being metal instead of ABS and that the intake end is more of a snorkel.

Any of the various other intakes with cone filters that lie within the engine bay of the car unimpeded would accentuate the sound of the turbo spooling.

Well, my data and fact were checked personally, but you knew that already...

It was pretty noticeable and accentuated inside the cabin, outside, etc. and going back to my initial post, moreso than stock airbox.... Maybe we are both saying the same thing and that's why I got confused on what you meant

So are you saying it's

1) Not louder with the stock airbox?
2) Louder with the stock airbox than compared with a Perrin CAI or
3) Louder with an aftermarket intake?

It's louder with Perrin CAI when compared to stock airbox and there is not much performance to be had from an aftermarket intake when compared to the stock airbox. Nothing more, nothing less.

I haven't put my car on the street yet so I cant attest to its reliability , however I feel compelled to add that these flange issues are limited to a 4 or 5 incidents on a kit that has been sold to a couple of hundred customers globally.

For a failiure rate as a % of volume, I'm sure it's nowhere near as bad as some people make it out to be.

indeed.

Indeed. I'm told that I've done more than 10% percent of last years total production numbers for the globe, which is about 30 percent of what what was shipped to the US alone. I do believe I have have more insight to this kit than most.

I have also done 3 Vortechs / 2 KWs / 1 JR / 1 Innovate / 2 ESCs & 1 custom top mounted turbo kit with a total of about 74 dyno tunes on GT86s / FRS / BRZs of assorted configurations. I confess, this does not make me an expert on all things GT86, but it does give me some leverage as to the experience my company has in this matter. And based on my experience, AVO has got my vote.

Having been doing R&D on other things with AVO (and other companies), has also given me a clear look into their inner workings, and if I felt otherwise, I wouldn't be working with them if I felt that their stuff was not up to snuff. Obviously, if I had as many problems as you and others might want to lead people to believe, it would be easier for me to drop the entire line and just do SC kits and get paid more, with less hassle. This obviously isn't the case.

Course, I suppose you're beyond suspicion, but I digress.

"pouring" was an obvious exaggeration due people willing to accept this and spending extra for buying new gaskets as "normal".n obvious exageration
unfortunately not many people state who did the installation.

my 2 cents on top of your 2 cents.

It's funny how both your posts come up at the same time, almost in unison. It appears to be concerted, but yes, your cause for concern hasn't gone un-noticed. Maybe you're getting the same turbo kits too? Meh. again, you're not getting this kit, we got it. It's cool, move on. Last I read it says it was an AVO owners topic.

Thank you for that clarification - I was under the impression that you were saying that the stock intake was more for the turbo sounds purposes.

Bob from @Drift-Office tuned AND INSTALLED my AVO kit and realistically I have ZERO PROBLEMS!! Quality is amazing to the point of it looking OEM.

I personally haven't had any issue with the kit. That being said it was installed/tuned by Drift Office. So as far as the flange issue is concerned, I don't have one. I can say I only have exhaust leaks from my catback (shitty slip couplings). Usually you should use flange gaskets when installing an aftermarket exhaust, I wouldn't think any different for a manifold... For the few that have an issue with the manifold, I'd say ask for a replacement.

i don't have a bias, i'm just confused about AVO response that there is no problem. Somewhat reminds me of Visconti's "looks good!".

If there was a problem across a large enough percentage of the headers, I'd say so. However, one reason people thought there was a problem had nothing to do with the flanges, but with the known quirks of a tubular Subaru header.

People that have actual problems with the flanges themselves being significantly warped, that will get down to me dealing with them on a warranty basis if they arrive like that. If they are like that after a significant usage period, then it will get down to how much boost they were running, how much timing they were (or were not) running, and how high their EGT's were when this happened. Unfortunately, not many tuners log EGT's when tuning out to high boost, so probably don't know if they overheated the exhaust manifolds. Metal is metal, if exposed to a high enough heat, it'll start warping.

This is my opinion as well. I bought this piece for the looks. Not for performance. As data has shown the stock air box is quite good.

It does sound much nicer with the Perrin.

[InvalidJohnny5]

Also I have about 20k on the kit, and am in rather rough conditions....hot exhaust temps in -20 weather should cause warping, but thankfully none have occurred.

I was thinking of getting the Perrin CAI, does the induction sound fairly naice?
