How is it better? Well, first of all, all EQT is doing is buying the same housings you can get off Alibaba, and having their name laser engraved into the machined area. Same thing Tomioka is doing as well. I will not out them as far as their suppliers, but we know who they are.

Tomioka now actually sells N54 knock off's of a turbo we designed 4 years ago, but with much worse flowing wheels etc, that is their business model.

As far as these "new casting" MQB units on the market currently. NONE of these turbos are addressing any of the factory inefficiencies, etc, etc. Case in point, EVERY ONE of them still uses the outlet muffler, every one of them is still running the restrictive factory style inlet. WHY? If you are having a "better" turbo cast for you, would you not remove unnecessary, poor performing aspects of that turbo?

The answer is yes, but the facts are, all the housings these people are using are simple factory housings recast to fit bigger wheels. No changes made to them. If they want to say that is not true, have them submit even one 3D drawing of their turbo in the design or casting phase. They will not be able to do so. Also if you are going to spend the time, and money to DEVELOP your OWN BETTER MQB turbo wouldn't you want to protect that investment and have your logos cast into the housings? Of course, you would, none of these people do it, because simply, they are NOT having these housings cast, they are mass produced copies of the factory housings, with various wheels stuffed into them. That is the difference between our turbo, and theirs. Ours is designed from the ground up based on the factory turbo for plug, and play, but it is NOT a copy of the factory turbo. This is why it's been 9 months since we ran multiple 10 second passes, and no one has run quicker, not even AWD cars. Its bee a long time, we acknowledge this, but it takes longer when you are not simply copying a factory turbo, and you are as picky as we are. We have refused multiple "final" production samples to get where we are now, do it once, do it right. FACTS...


Do you have proof oh how much inefficient the turbo muffler and the outlet is? Have any data that provides hard numbers? Most people upgrade to a Muffler delete and a bigger outlet. Once that is changed, do you still feel those parts are inefficient?

Very interested!

Proof that the turbo muffler restrictive? Do a quick google search of how many MQB turbo muffler "deletes" are on the market. Why does the aftermarket delete things, such as cats, mufflers, etc? Because while they serve a factory purpose, emissions, sound, etc. When it comes to performance they are a hindrance. Hence they are deleted when performance is your main goal.


As for the inlet. The factory design introduces multiples connections right before the compressor wheel and also limits the size of the inlet. From a performance standpoint, you want the smoothest possible flow into the compressor wheel, as well as the largest possible opening. The more air you can get into the turbo the more easily it can flow. The inlet size is actually much more important than the outlet side, but we have addressed both.

Hi Tony. Looking at that 3d printing image did you switch that housing size based on is38. I remember your prototype was an is20 housing.

What bogus logic. Yes, some of the parts are performance oriented - the rest of them are there to separate fools from their money. If you can build it and say "it may increase performance", there will be someone with confirmation bias to prove it works.

Yes, there are a ton of turbo muffler deletes on the market - and there are nearly as many threads documenting how the delete doesn't do a damn thing.

Lol rather than a google search we'd have preferred some in house research, maybe some cfm numbers, something tangible.

Not saying it DOESN'T, but...

If you prefer turbo mufflers, and multiple connections before you compressor wheels you have many options to suit you needs. As far as logic, we are not speaking from logic, we are speaking from experience. 40 years of it, but hey what do we know. Keep doing what you do guys, we will keep building products with things removed that serve no purpose, and hinder performance. People wonder why do not come in here much, its because we have no time argue with people about why putting a "muffler" in your turbo outlet is a bad idea. Next time we have an update we will be back. Until then, Cheers!

Nothing has been switched. The very first sample we tested was simply our CHRA in IS20 housings, we never had any housings made modeled off the IS20. That housing designation be it IS20, or IS38 is no longer valid, as the internal dimensions of our housings are completely different. The remain stock appearing externally only.

So do you have a release date yet out of curiosity??

So your whole logic that the turbo muffler is hindering performance is that "we are not speaking from logic, we are speaking from experience. 40 years of it,"? There is a fallacy in your argument there...

I prefer logic, science and hard facts. Experience is great to help make design choices, and then science tells you if it is actually any good.

I love these posts by Tony. They serve to build up more animosity and contempt for him and VTT than anything positive. At least that’s the impression I get. When I read these posts it seems like everything is “we are the best and we don’t have to prove it, it’s because we say so and all that disagree don’t know any better. P.S. all other turbos are crap and made in China. Peace!”

What should he do, knowing all of the direct attacks he's receiving? Most from people who have no interest in the turbo and are only posting to harass him?
