you do you realize when a prototype is being develop you can not expose it to the general public? if a 3rd party company is developing a product for a company and they release pic/information about what is coming up they can and will be sued by the company they have a contract with. i dont understand why your trying to bash on Mac, is there something deeper that happen between the two of you in which you should enlighten us about? is there anything you can bring up that can back up what you disagree with when it comes to Mac? i personally work for an automotive company and a lot of things he brings up about companies development is dead on correct. as far Mac custom making turbos, well i havent bought from him personally but i know quite of bit of people who have and there not a "cheapturbo".

I've had many dealings with Mac and love the products he designs. Hell we talk on a daily basis. So I know what's coming up next and it's going to be huge. Of course it will take time considering what he's trying to accomplish but the end result will throw the turbo world a curveball and will pay richly.

In the 8 years I've known Mac not once has he lied to, or tried to mislead me. He's a very straight shooter and does so for all of his clients.

 

Uh oh. Just got an eBay time bomb lol...

 

Funny last issues of Super Street was a turbo issues and it had the most popular turbo companies and guess what 2 were in the list.... CX Racing and GodSpeed lol.

 

I believe it. Less than $250 shipped for a GT45 is hard to pass up.

 

I passed it and bought a real Garrett t3/t4, I didn't find it difficult to pass up

 

You're obviously in the minority then. Hope that turbo works out for ya.

 

more like the majority sir! its been over a year (12k miles) no leaks no shaft play still solid like the first day i got it in the mail. yes i drive my car daily and its not my daily driver either. of course this debate will go back and forth but the fact of the matter is...i just have better turbo.

 

Well if the knock offs are the most popular as reported, that means you're the minority. Congrats on getting the "better" turbo, I hope that's consolation enough when this eBay knock off makes more power. Lol

 

How many winning race teams are running ebay turbos?

 

That would be none

 

Lol, you think I go out to the track and keep count or something? I'm not building a race car here, not trying to win any class championship, and I don't have sponsors to fund the car like those teams.

I do see a lot of similar combinations running 130-140MPH 1/4 mile with eBay turbos and no issues though. It's just a street car with a $300 junkyard engine in it.

 

To make a fair argument lets make sure you have the same trim turbo as me and let's have the same tuner tune it. I'm glad your happy with your low cost item but you do realize it's the same as the real thing, when you can admit that then it's all good.

 

Yeah, it's not even close to fair.

I know it's not the same as a more expensive turbo like your Garrett, never argued to the contrary. However, I'm willing to bet that it will live just fine and make good power even though its an "inferior" piece.

 

Cool beans,
If you don't mind, share your Dyno results when your done

 

Will do!

 

I'll simply say this, then I won't comment again on this matter as its beaten horse so dead, its just a stain on the road.

I do not like these knock offs not just because of the fact that they use materials that are rather inferior, BUT, because they use inferior parts and claim that they can take the same amount of cycles at the same boost pressure levels as the major names.

What I've found over the years is that most of these companies will improve upon their designs only where they initially see problems, and then call them "new and improved".

For example. Everyone remembers the image of the compressor cover that cracked in half several years back, right? Well, these companies realized how bad of a name it brought to them, so they changed their material designs.. BUT NOTHING ELSE, for several years. After that, another portion would create a trend of going bad, and they'd slowly change that aspect of it as well. You do that enough, you basically come out over the years with a product that actually improves to almost do what a Garrett will, so much that this debate continues.

Here's the rub... These knockoffs STILL have not changed their bearing design, their turbine housing materials to be more robust or their turbine shaft material design, as these the MOST EXPENSIVE parts to alter. Because they know that the average purchaser is not going to push their turbocharger to test even remotely the limits of these materials, there was no need to change them..

Over the last 8-10 years, I've not once see anyone push these turbos past the 25psi limit (just a number I'm using over the typical 8-12psi that is normally associated with them) or have any longevity from being used for HIGHER THRUST LOADS, that those with a Garrett or BW would see because they know what their intended use will be before they even make their purchase. To hell with dyno numbers, that's child's play. Until I start seeing some real thrust loads and high rotational speeds on a consistent basis with these turbos will I give more credit to these companies. But I have yet to honestly see that.

For every person that says "I've seen the real companies turbo's blow up too.". Of course you have. But did you ever understand why it did? The answer is because they more than likely didn't install it correctly or had other issues going on with the car at the same time..To a point where any turbo, regardless of company make would have likely failed.

So, the majority of those that purchase these aren't to just prove that people are wasting time and money with Garrett, in a meager attempt to reinvent the wheel, but because they are unsure of how their mechanical ability is to install a turbocharger, and don't want to take the risk.. Which is really, rather understandable.

So, to those that utilize them.. Prove it to yourself and not the public. It changes little until we start seeing some higher thrust loads and boost pressures. The 8-12psi stuff proves nothing...

All I think about is THIS poor guy and his review.

Sorry for the book..
ONE!

 

I remember that guy in the link lol

 

Dude you are the one that just got an Ebay turbo, he got a Garrett. How would the Garrett not work out, much better turbo than anything from Ebay. The reason the majority gets theses cheap turbos is because 1 people just dont know and 2 they dont listen to those that do know and have been around the block a few times. When the turbo blows up and takes out your motor you will be wishing you would have spent the extra $300 on a Garrett. The minority are the ones that know and stay away from Ebay turbos. I would send it out and have it balance checked and have the seals replaced with Garrett seals, this seems to make the Ebay turbos almost as good as a Garrett.

 

I know of none and for good reason and I have never seen a car in a mag have an Ebay turbo either. Its all about quality and Ebay is all about quantity.

 

And be sure to post regularly to report on the health of your turbo.

 

Sorry to disappoint, but it probably won't be pushed very hard. 15-18psi is about all its going to see, but it should be more than enough. No attempt to prove anything, just wanting to build an affordable turbocharged street car.

We'll see. The last thing I do is listen to Internet banter because most of you have little to no experience on the matters you speak about. Now I've been seeing guys with these cheap knock offs at the track over and over and they're making power and holding up well! It's hard to dismiss that because of a bunch of guys regurgitating what they've read about these turbos.

I have. It's pretty much what got me seriously considering a cheap turbo.

Lmfao yeah right. I'll give you numbers and update if/when the turbo dies.

 

How many "winning race teams" are using cast manifolds? How about stock camshafts? Does that mean they don't work or are a bad choice?

You don't necessarily need a bunch of 1000whp+ parts when building a 300whp car so the "race team" litmus test isn't really relevant.
Just curious, do you have any first hand experience with 'ebay' turbos?

Not venting on you, but it seems there is a lot of "forum" experience on this subject where people that have no experience with the product want to tell everyone how shitty the product is. Not arguing they're good (nor do I have any experience with non-OEM manufacturer turbos) but the consensus on a different forum where a lot of people do have first hand experience with the 'ebay' units is very different than the group consensus here.

 

Oh no no.. I won't be disappointed at all. But you are following right within my premise for the use of these as stated.

Its not an "I told you so" statement as much as it is a "Yeah, he's doing just what most in this arena of use do."

I'm not worried, scared, or emotional.. Just.. indifferent.
