JHM Rs6r turbo. What really is it

B5 S4/ RS4
#81

as I said in the other thread, I think the thing that sticks out like a sore thumb here (well, other than DxC ‘fucking’ with these for years, but never actually testing one until last week…that doesn’t sound like he was very serious about it)

That is that one company is a legit, operating company with accountability, accessibility, has done a boatload of R&D, and continues to do so…and the other company is a guy with a history of stealing/copying others, who may or may not be working out of his house’s garage. He and his distribution channel (lol naudlee) are working from the seat of their pants, with no phone number, no business location, and no business to speak of.

I think it’s pretty clear who the obvious choice is, for those in the market…and for those wondering who to listen to. I’m all for being a startup, but you can’t be a startup forever. You have to step up eventually.

I really really really appreciate this post, I had a HUGE response typed up, but my computer battery died and I lost it all!!! SO upsetting. It was nice meeting you, even for just a second at the track. I didn’t mean to be prying at any secrets when I asked what turbos you were running, I honestly just wanted to know because I am a curious guy! I am sorry you had issue there, hope its something simple like valve float, rather than anything serious.

I had a ton of good points to make about my history as a Mechanical Engineer, my appreciation of all the information you have shared, and such. As well as my dislike of Naudlee and his practices, especially with regard to his bashing of VAST and JHM.

On to this post, the biggest thing I wanted to ask was what exactly is the difference between the China LD turbos and the HD turbos?

Is it the bearings, housings, any other parts? I only noticed you specifically talking about the quality of the “virgin bronze” bearings. I’ve only had a small bit of research into the manufacturing processes of sintered bronze bearings, but I do know a bit about material quality and scoring resistance. Is there a specific bronze family that was better than the knock off crap the China turbos used?

Where are the HD turbos from?

Are some of the parts sourced from china, and others to other places?

Didn’t mean to be rude. I was there with the family and it was the wifes car. We had to leave by 3 to make it to dance for my daughter. The motor is fine. It was the transmission that took out the case. kinda hard to float a valve when the transmission shifts at 6600.

Ill get a post made later to cover some of your questions.

Ahhh, that makes sense. It sounded like your trans misshifted and the revs skyrocketed and then white smoke! So my first thought was valve float, especially when we heard you drive past, it sounded just like when I floated my valve. Hope you get it sorted, was a great looking car!

#85

It did miss shift. I don’t know if you heard on the first pass I let out when it went into 4th. When it shifted info 4th the gear slipped so I backed out of it short of the 1/4 mile. I assume you guys heard it as Adam mentioned it. While In the pits I had a file I made with much higher pressure in 4th. I also had a dial on the seat to control pressure. I don’t know if you saw it but I had the TCU on the floor and a few knobs on the seat.

The Second pass I turned off the ESP and launched the car light off the break. The 1-2 shift was super hard and quick. The 2-3 it snapped a little so I turned up the pressure it held but on the 3-4 shift it came in too hard and too fast. I shared off something big as it went threw the case revs went way up hit the limiter for the motor 6800. Then I said F it and stabbed it again and that kinda just reinforced what I already knew. Took her into the pits. Checked out the car with a once over. The TCU had all kinds of codes so I just put it into limp mode and drove her out of the track.

That is funny. Do not try this at home!

Funnier still is watching epl try their best to look like a vulture/cockroach/rat all rolled into one in the aysix blown motor thread on audizoo.

#87

The real key is I just want to know if some of RS6-R is made in china or not.

#88

thats what I got from the 4 pages

#89

did you miss all the parts where “some are from china” and “china ones will look identical” and so on?

#90

where did anyone from JHM say RS6r turbos are from China?

I believe they said they let another company make a low duty version, which is made in China.

#91

That means some of the “many versions” of this turbo are chinese turbos.

#92

Man if u read the actual thread the answers are all there. There are 2 turbis in quesrion the light oe LD UNITS the turbo that dcx copied the ch8na turbos developed for oem replacement and not performance repoqcemets. The LD units were close to tue first few test turbos from several years ago and then there are the much m9re robust HD units. Turbos that only jhm has turbos made w8th better parts better materials and much tighter machiene work and tolerences. The HD ujits need to be built with a more hands on and direct approach. Tue result of this is parts made in house or special made not something available on the market. When you build st7ff like that you tend to have it made local so you can assure quality

Seems kinda cut and dry. I know with all the attempts and changed stories by the attempted copiecat people have made things confusing but if yiu reqd it has all been spelled out quite clear. Or so 8t seeme so to me

#93

Well yes if you include the Chinese knock offs made by copycats like DxC or the low duty version made by are (I think)

But those are not rs6r turbos.

Anyway, that is three versions. Where’d ‘the many’ come from? Did you mean ‘the three’?

#94

man your feisty. I did miss the parts where some are from china. As there is the LD units that have been allowed to be made in china. That is where it ended. It was to me… made clear that the HD units were made in a controlled environment not in china.

Here is the thing. If you have a little money you can get parts copied in china. If you have big money you can have parts made in china BUT you can also have parts made in other parts of the industrial world… and here is a secret. China isn’t the most cost effective. China buys all our old industrial machinery and our scrap metal. Other parts of the industrial world. Pay big money for NEW and the most update industrial technical machines. They want your money if you are making parts. Just thought I would add that for those of you who don’t know.

While I can’t speak for CV personally I know of him and I know he has worked with borla and several other companys over the years. Lots of people know CV. I don’t know the particulars of this project with the turbo but I do personally know CV has used the other part of the industrial world to make a few parts that the domestic guys see. Being as such I don’t see why he would leave the better world to start working with china.

Hope I haven’t shared too much.

Funny shit…the psycho path got a perfectly acceptable answer, then followed it up with this explosion in another thread
