HOLY CRAP! Billet compressor wheel for the factory turbo.

Hmmm, the more I look at it, the more I'm thinking its flank milled. Meaning: second order surface.

You generally want to see point milling on these things. IOW: third order surface.

Layman's terms is the blades are not going to be as efficient as they should be due to the limits in the shapes/dimensions you are limited to with flank milling.

I'm quite curious to see what shows up in the mail now.....
 
Got it installed, so now we have to wait and see if the customer notices any differences. He took some pretty good notes.

BTW, the shaft hole needs reaming, its way too tight, luckily the machine shop around the corner had the right reamer.

Pics later.
 
I talked to him, he's going to make sure the wheels shipped out are reamed out and the manufacterer will fix them at the source.

Weight wise, the OE wheel was 74 grams, billet wheel 61 grams.

The material removed from the OE wheel to balance it is nuts, :(

Well that's just bloody great. Mine is already in the mail and no machine shops in this bloody remote location that I'm stuck in for the next two years.

If it doesn't fit, it's going back for replacement or refund.
 
Sorry, fell asleep, pics later, lol.

Also, I ran it without the compressor cover and it was true, so that's a good sign. :hihi:

Customer called and left a message, he's very happy, said it seems to have more power. Will call him and talk to him later.
 
Totally disappointed in the guy that's selling these wheels as turbochargersystems.com.

I just sent a message on Ebay yesterday inquiring about whether there was a sizing issue with the wheels. What I got back was totally unprofessional and I got a world class scolding about how there was nothing wrong, and that if it didn't fit I had no business dealing with the wheel. I got three 1/2 page messages from this guy chewing me out.

Oh, by the way, he said that everyone on this forum is an idiot... Just saying. Guess you are then?

He's got one chance now to make it right or he's getting the negative feedback.

So, I tried my wheel last night. Took a shaft and tried to install the wheel, not possible. It only goes on 1/4" then stops in a bind. I took two other compressor wheels and tried to install on same shaft, went on smoothly. Hmm, not the shaft huh?

I wouldn't by a single damn thing from this guy after this!

J
 
Never mind, this seller sucks I'm so pissed of what he wrote. I'm posting the negative feedback. Steer clear of this piece of crap!
 
Good job for inquiring and standing up for positive craftsman ship chevydiesel. I'd have done the same thing. People like that are just scared because they sell crap.
 
Sorry to hear that, I talked to him and he acknowledged it didn't fit right as did the manufacterer. Oh well, so far, my customer is very happy with it.
 
Here ya go:

Here is the simple question I posted to him:

Dear turbochargersystems,

So, I've read on the forums following this wheel and discovered that some others are having trouble with the bore size being too small for the shaft. So, I tested the one i received on a spare turbine wheel shaft and sure enough fits too tight to even get it to go all the way onto the shaft. This was compared to a stock wheel. So what's the deal?

Here are his THREE replies:

"We have heard a little feedback on this issue. There are a lot of different turbo manufacturer's out their manufacturing this IHI GM1 thru GM8 turbochargers (IHI, Borg Warner, Rotomaster, and last but not least: Chinese knockoffs). The shaft size has been known to have as much as .0001" to .0003" of an inch variance. A piece of notebook paper is roughly .003" of an inch thick. That is over 30 times more of an increment or thickness than the variance that we have seen in the shaft dimensions where the compressor wheel sits on the turbine shaft. The IHI shaft is exactly.2795" when measured with the proper tool. We use a new Mitutoyo Model IP65 micrometer that is as precise of a fine measuring tool that money can buy. We use precision "gauge pins" as well for measuring the bore of the wheels as well. We can easily slide a .279" gauge pin through the billet wheel we sell (it will actually fall through if we invert it) and we cannot slide the .280" pin through. The only way known to man to measure finer or smaller increments than this is a laser. that kind of machine will never be found outside of a multi million dollar manufacturing process company. It is the intent to have people employ the services of a qualified turbocharger builder to be doing the assembly and rebalance when doing upgrades. A professional turbo shop will face variances and have tooling to address these minor issues when and if they arise. We offer this service as well. We offer to sell this wheel with no mark up when someone sends in their turbo for a rebuild. Many people now days assume their is nothing to building turbochargers. That is a fairly common mistake. It may be the wishes for everyone to have their cake and eat it too, but the reality is that specialty parts and specialty items require specialist's who are actually trained in their field of employ. "

And...

I just took an authentic IHI Shaft and one of our billet wheels we sell for this application and slid it right on by hand to it's correct position on the shaft with very little effort. Then did a reversal and took it right off by hand with very little effort. No problem. Will I argue with people on forum's: NO. Pretty big waste of my time to attempt to educate people who cannot or will not hire specialist's to do their specialty work. Everybody is a turbo specialist now days. Just ask them people on the forum's they know far more about sizing, application, installation, problem solving turbo issues, turbo assembly, turbo selection, "who is and who aint". I have found over the years that Diesel tuner and repair shop owners and mechanics to probably be the worst place to ask questions or advice when a turbo issue arises because they have just a little bit of knowledge but truly not enough to actually find the real problem. I know a diesel shop owner that absolutely must have the most powerful truck in a 3 county area, so what did he do? He went and spent $40,000.00 buying a patent right and a half dozen ball bearing turbo's from one of the three largest aftermarket turbo companies in the US. Only to install and attempt to tune his monstrous turbo ($2500.00) turbo to be exact, and realize it flat does not work on his application almost at all. Horrible surge at 16-17 psi when he wants 40 psi. Do you think he would step up and be man enough to admit he is outside his scope of knowledge and skill. Shit, who are you kidding. He apparently thought his wasted $40,000.00 was easier to deal with than humbling his pride and going to see a Turbo Professional. Glad it was not my $40,000.00=OUCH!! When peoples pride stands in their own way: that is on them and no one else. My suggestion: hire a professional. Not someone who thinks they are, and stay off the forums. People on forums are looking meet their needs in ways that should be met in other ways. Nothing but trash talking.

And...

People on forums are pretty sketchy at best. And that is on a good day. Most of the audience is made up entirely of enthusiast's who have no formal education in what they are trash talking about and have very little understanding about what they wish to accomplish because they are too frugal to hire real specialist's or just plain and simple can't afford too. But, by God, we are still going to have our cake and eat the damn thing too! And then trash talk the real specialist's who can easily resolve their issues but won't get hired because Johnny Boy's little wallet is just a little too lite this month because Johnny just had to go to 2 or 3 night's a week to keep up that sacred vow they made to their wife by wasting what little money they had on lap dances and alcohol. So now we have to make up that savings loss and "Do it ourselves" when we are not even remotely qualified and when it does not go just right (did I mention that 99.9% of all people are not qualified to work on turbochargers?). Now we throw our little tantrum's and cry foul because we wasted our money, chose not to hire someone qualified, and have a general overall malaise. Now what? If you would like: send me an offline email address and I can send you a 30-45 second video clip installing the wheel on to the shaft and then removing it. Issue solved. Pie holes globally closed.

Then I posted in reply:

"Dear turbochargersystems,

Sir, wow, I mean WOW!

I got a great scolding here after making an inquiry about a product you've sold and support. Way to go on the defensive.

I on a forum post that's studying this wheel and whether it works as advertised that the shaft hole had to be reamed to fit the turbo being installed into. The poster said he had contacted you about it and that you said that future wheels would be reamed to an appropriate size. That's what I read. I cannot vouch for the forum posters turbo, whether it's a OEM or knockoff turbo, but it seems as though it's an OEM.

I grabbed an OEM IHI turbine wheel and shaft that I had outside of a turbo to test fit it and it wouldn't go but 1/4" on the shaft. I used a light oil on the shaft to see if that helped. It did not. I compared the fit to two different IHI compressor wheels I have and they both fit the shaft fine. This billet one did not.

No, I'm not a turbo builder by trade. I have rebuilt them. I don't claim to be an expert, but I have installed a few compressor wheels in my time. None of them this tight.

I do not appreciate being scolded and I'll give you one opportunity to make this right or I'll just have to eat this one and report where I can as well as grant you the currently owed negative feedback on the transaction.

Thank you and Have nice day.

J"

So, the heck with it, I'm posting the negative feedback...

Then His Reply:

"It was not my intent to scold you. I speak of the vast majority on forums. If you have to go to forums for information you are going to the wrong place. What would you like me to do? I am more than willing to help solve your issue, but you have made no request for a solution. Send your wheel back and I will gladly refund your money and shipping. I will gladly send you another wheel test fitted to an IHI OEM shaft prior to departure on it's way to you. If you would like, I will gladly balance your rotating assembly for free. I would even do a whole rebuild for you for free if you pay for shipping. I am offering you a way to resolve this and come out way ahead. Now you realize if a wheel slips through that is slightly out of spec from the manufacturer that is beyond my control. No one pulls brand new parts out of a box every time to see that everything is perfect. That is the job of QA/QC department at the manufacturer. My job at this point is too assist in correcting the problem. This is what this is."

Then I get more of this...

"You were a little quick on the draw there. Consider the offer rescinded. Hang out on your forums Little Johnny!!"

Then I send this:

"Dear turbochargersystems,

I've already posted the negative feedback.

You succeeded in your scolding and managed to anger a pretty level tempered person.

I'll just throw this piece of shit in the scrap aluminum pile.

I'm done discussing this with you.

Have nice day

John"

His final Reply:

"Level? You must be using the one from China...LOLOLOL"

P.S. "Have Nice Day" is code for Go F Yourself :) That's why it's missing the "a"

Feels like I'm dealing with John Kennedy or something (that's not a good thing btw)...
 
Oh, ebay already removed my negative feedback. That's why ebay is still and always will be a pos, cause their feedback system has no teeth.
 
Same customer service I was told about WRT his rebuilt GM-8s that failed w/in 3000 miles...15 of them. Customer's problem, not his.

You probably dodged a bigger bullet by not taking up his offer to rebuild your turbo (not that you would have but still)! Seems A-1 has a brother in the Turbo Fleecing business, Herr non-Turbochargersystems, Mr Barnes.

Never had an issue with John Kennedy, although I'll grant you he can be blunt.

Live and learn I guess. Mine will gather dust on the shelf or serve as a conversation starter.
 
Yeah, none of that guy's offer to make anything right would have been genuine. I got that distinct impression that I would have gotten screwed even more than I already was by buying his POS wheel. I went through this with John Kennedy a couple months ago and it wasn't pretty. I held the short end of the stick in the end. That's for another post another day.
 
I hope it works out for you and your customer as well as for Great White.

A lot of people hammer Walt at SSD but I had a few good experiences...until the Injectors and GPs failed. Lessons learned the hard way suck.
 
It does look good. And despite Barns' attitude, I hope it does work and perhaps he just goofed and gave the machinist an off measurement of the shaft. Either that or an honest mistake by the machinist. Curiosity I guess but I may take a few minutes and see if mine goes on this GM-5 of mine or not.

What's the torque on that shaft bolt anyway?
 
Nice . . . Blaming the customer for the product repeatedly not working as advertised. Were it me, I'd get over the 'it works in my test shop' stuff, get my hands on units where it does not work to learn the variances, and then correct the product. But that's just me, and what I actually do when I build things for other people to use.

I know, sucks he's acting like that, :???:

It won't fit, and torque? I honestly have never torqued a compressor nut in my life, I'll get flamed for it but never have on the many turbo's I've dabbled with over the 12 years and never had an issue.

Its out and he knows it, which is strange he was doing that. We talked on the phone and the maker also said it was out, :(
