And of what value does that have to do with this discussion? Let’s stay on topic.....

To everyone: If you have no questions regarding your Turbo’s performance or input to add please refrain from posting banter

...since you mentioned it

Here's a 3rd gear pull from today:

And a 4th gear pull:

https://datazap.me/u/snice/3rd-4th-g...6-7-8-9&solo=4

I pulled off some parameters to get a better sampling rate (OBDeleven).
I think these show the overboosting I've been complaining about. To my novice eyes it seems that once I start overboosting, the throttle is being cut. Hoping this is a wastegate/spring issue that can be solved with a wastegate upgrade?

That's all we wanted to know. I have been trying to produce a database of K04 hybrid cars for a while now to compare results, but its hard to extract this kind of information from people.

[Traptalk]

In other news been running my tcu file from BG and I’m pretty impressed so far

I would only use manual mode with paddles before because my stock tube rifled thru the gears as quick as possible and was unbearable to drive in D/S

Now it seems like all 3 modes have uses

Using D in traffic commuting was very smooth and effortless and the fuel economy was great. S mode was too aggressive almost for rush hour traffic but it’s great when get to open it up a bit more freely. Get a lot of part throttle shift farts now as well.

In manual mode the shifts feel so direct and precise. Very crisp. Even the downshifts. A lot less lag for sure even just at part throttle. Mostly noticeable is the hanging in first gear sometimes was gone.

A lot of shift farts now lol

Wish wasn’t snowing already :(

You have proven documented results that your turbo and tune runs as good as APR V1 did in 2014 is what I think you meant to say

And if you look back when JHM first introduced the K04R you would learn that it was just going to be a turbo option with no real plans on doing software for it. As you found out the hard and expensive way, tuning your ECU isn’t exactly easy.

You guys like to blame me for threads going sideways but really, it’s your inability to admit your limitations and admit that you don’t really know what you’re doing. You’re arguing with a company that does this for a living and has made some pretty decent passes on pretty decent hardware all the while you guys are making every possible mistake you can. And some how in your twisted logic you think what you’re doing is better. JHM isn’t perfect and they have all the same problems any medium sized business can have.

It’s easy to give them a hard time when you slapped together a turbo and got some guy in his garage to tune it. If you tried to do this for a living you’d probably fall on your faces. But you’re just some guy who built 1 turbo and got some other guy who doesn’t know how to tune it or doesn’t have the right equipment to do so if he does know how.

The fact is, every car in this subforum running a K04R and APR V2 or 3 runs better than your eBay turbo and HP Tuner tune.

Sorry to be blunt but you kinda need to hear this.

no what Jake proved is that a b8.5 allroad running e85 can run 12.3 we already know the 8.5 with k04-0064 can run 12.1, and you still have not shown us a single b8 that is not on meth running less than 12.8

So we agree that EA being here is a catalyst for a derailed thread anytime he posts? We definitely know what the problem is.

Jake just came in here and asked if you guys would be interested in a TD05 for your car and you guys pounced on him. That turbo is well suited for this displacement and is a 400-450 capable turbo that spools fast.

The company he works for is a forum sponsor and keeps the lights on. You might want to say thank you instead of shitting on them.

And it’s your ignorance that keeps derailing these threads. I came here trying to help you guys set up your wastegates and got nothing but arguments from people who never built a turbo before. You guys kept telling me I was wrong and now all of you guys are doing what I told you to do. Up the pressure. 🤣🤣 I even gave you graphs showing that boost moved forward and MAF gained. You guys didn’t even think a K04 could reach full spool before 3K the way you were going.

And yes, I had a bad experience with JHM because my wastegate was set wrong, a mistake which was easily adjusted and a bad tune. BUT, JHM made everything right with me. I even got a call from the owner and we talked it all out and I was taken care of. Dru, Jake and the owner all wanted to make things right every time I spoke to them. The owner will be handling the tuning going forward as I heard it.

The EBay thread was an awesome thread. I just wish you guys would actually listen to people. 🤣🤣

Instead you guys just played follow the leader off the cliff like lemmings.

You didn't overlook anything! I had "accelerator position" graphed before. This is the first time I captured the throttle.

Definitely no stutters or jerks. I'm coming from stage 1 so compared to that, car feels like a beast. It's probably limp - I just don't know any better. Looks like the throttle cuts out very early. Car is trying to save itself.

[Iceman502]

So, I worked with my tuner today logging and emailing data back and forth and got some adjustments made for high altitude. I only gained 4 g/s of airflow to 267 g/s but spooling is quicker and boost delivery is very smooth. N75 values max out now at 92.5% instead of 84% which has me close to requested boost. I may get one more revision to adjust for erratic timing advance in the mid-range but I think this is as good as it’s going to get on 91 octane and 5,000’ elevation.

Next up is experimenting with E85. What, if any, gains in MAF values will I see using an E40 blend? (flex fuel CPMA)

Version 41?!?!? Not to beat a dead horse, but damn that must be nice lol

I know you're using the CTS K04 - did you ever check/share the wastegate setting you are using? I feel like you did but that is buried in the old thread.

[Coldcarnival]

I see I've been quoted what's up guys, anything I can help with. Still have the same set up, 3rd motor but the turbo is still going

Funny - I thought you guys knew about that! When I got the CTS K04r -1070 - I figured when I wanted to 'tinker', I could DIY upgrade to the K04x. My research lead me to the original the ebay K04 turbo thread. Y'all were doing it already!

Yeah, that K04X has been on the site for a couple months. It seems to have replaced the CTS BW K04 since apparently it was/is unobtanium.

It seems like your drop in load and the over boost are a product of the throttle closure

The boost builds as it has a serious restriction now getting into the motor and essentially has no where to go but build

So I believe maybe your wastegate is too high for the file which is triggering the throttle closure

So before you buy anything or pull the turbo try the higher spring file and post the log up

As I experiment with an E85 blend I’m probably gonna need a few more revisions. 😏 I may need to have my fuel rail pressure increased but for the most part this thing is done!

I checked my wastegate pressure before installation of the CTS K04 and it was a hair under 9 PSI.

Product description is seriously vague

My interpretation is that it’s exactly the same as the normal 1070 kit but with a clipped turbine and maybe large oil port bearings like my Chra. I’m gonna assume it’s the same exact compressor or +1mm

Absolutely no description of the blade geometry, profile, sizes, or features

Thanks we were just trying to get comparison for times for b8 with k04 running straight gas 91/93 and your slip was presented as being a b8. I assume your running a zf8? any tcu tune? meth?
Take care,

I apologize for helping derail the thread. As to my original question about the interest of a TD05H-R, if we proceed I will create it's own thread.

I dont think you are derailing you are just offering more data points. we would just like more specifics.

I’m running CTS’ previous version of the K04 1070. Is this a bigger turbo? When I got mine I paid $1,250 while it was on sale so I hope there’s more to this new one to justify the added cost?

They imply the compressor wheel is at least. Sounds like it’s a stock k04 turbine that’s been clipped.

Not sure it’s worth that much of price difference but maybe on sale it gets cheap?

Someone is going have to guinea pig it on k04 software tho

It says it works on any “k04 hybrid specific tune” but as far as I know every tune out is based on a k04-0064 from Borg Warner and not a hybrid model

my bad, i misread his profile but again not a b8 and he ran e85 at 104 octane with a e85 tune. Would really just like to see what the b8 is capable of,
we all know the caeb is not as fast as the b8.5 so it really isn't a legit comparison and my comments were not directed at you. EA is the one that keeps claiming that we dont know what we are doing and everyone is faster than us but has yet to show us a single b8 and instead always points to B8.5 cars running meth to try and make a misguided point.

That APR time slip of 12.8@105 was in 2014 and on 93 octane. So unless he threw a K04 on a car that still had 3 years of warranty left, it’s safe to say it was pre facelift. 🤣

I could be wrong. Cory’s Sig doesn’t say and I don’t know him.

Me neither. People have done crazier things.

My whole beef with the eBay K04 thread wasn’t everyone trying to make a good turbo for less money. It was the arrogance of some posters thinking that every other MFG was just buying the same cheap turbos and marking them up. Even in this thread some people still think the K04R is just some China turbo. It’s not. Guts made in the UK, has some BW parts too and the CHRA is based off of their RS6R turbos which they’ve been using for quite some time now. And the people running that turbo have cars that run right. My B7 with the K04R was probably the best running K04 car in that subforum. My CTS turbo runs great too but I get quicker spool and a little more flow than with the K04R. A4X’s car runs great. And the guy who just posted his time slip got a 110 MPH trap speed with one. Guess what, the K04R is a pretty good turbo. 😀

Now some people actually think CTS is monitoring a thread about eBay turbos and making huge financial decisions from it. 🤣🤣

You can’t make this shit up.

Lol that guy was me

Although it may be coincidence since the eBay thread has started we’ve now seen newer Chinese hybrids like the tbo that seem to follow some of the ideas we were playing with in the eBay thread, like different blade geometries and adjustable spring/piston wastegates) as well as two different budgeted cts options now, one following the clipped wheel trend.

Again could be total coincidence but I mean if you were testing the waters for a new product wouldn’t it make sense you would see what the community is up to and try to fill the void where the demand is needed? For us it’s obscure k04 hybrids 😂

Wonder if they’ll make an in between turbo between k04 and their boss kits or if that’s what this X model is supposed to be

Look forward to the data either way
