^Interesting is an understatement! Gloves are coming off the Avant, and she will be ready for another great track day in May.

Really like the look of this!.. should work right up with Apr's new dp as well.. unlike cts's

Planning this out, how is everyone adapting IC hose sizes? Trying to get my shopping list in order....the JHM kit says it drops in like the factory turbo, meaning it likely uses factory IC hose size, which is what, 2.25", 1.75"? I'm planning on installing the ECS IC pipe kit at the same time which is 2.5", are there issues with using an silicon adapter up to that size? The ECS kit comes with a turbo muffler delete to adapt it up to 2.5" which looks like it controls turbulence better than just sticking on a dumb off the shelf fitting.

[A4 Centaur]

^I'm going to keep my factory hoses, though I am running the APR FMIC. I assume those hose (Stock) are 2.25"?

JHM is telling me to get with the program so I don't miss this next batch of production K04-R's

[earhythmic]

^^^ya I'll be going with the APR FMIC too, installing all at the same time. Guess I can figure out all the proper fittings on the bench before I make my car undriveable and need to make a run to Autozone.

Man, all this talk of hoping on the JHM train has me chomping at the bit! Earhythmic, you know I'm gonna be banging on my 6s when you're about to do your install!
This thread is heating up like Kim Jong's uranium enrichment program!

I'm also in the same boat as you! However I should save the money as a downpayment on my next car!

Can someone please explain to me what all the hype is about the JHM kit? Yea it looks nice. I suspect the hype is because the kit come in $1200 less than APR (however no software included), and suspected quality is better than Frankenturbo (although not proven except based on JHMs reputation??)?

[A4 Centaur]

^ Well for me, its about the modifications to the wheel, ceramic heat coating, and other details like it being a direct fit.

Price is overwhelmingly the main reason, but again, not having to buy another HFC, when I just replaced mine after it cracked is a big plus. Also, I don't think APR sells their K04 with the tune included?

Regarding mods to the turbine wheel, I have seen the same techniques used on the Borg-Warner VNT-15 for the VW ALH TDI Engines. Kerma TDI offered which as I recall was a VNT-17/22 Hybrid?

Anyway, I found those points of their product interesting and potentially will make the build a bit more interesting and hopefully this project will lift up B8 modding a bit. Really, this platform could use some help in the power modification dept.

[A4x]

^^ So with the added features of this turbo, do you see a benefit of going Eurodone or some custome software as opposed to APR software, in order to maximize the potential of the turbo?

Also, I thought APRs $3000 kit included their software.

[OzeyeruZ]

APR Ko4 $2999 (for Existing APR Tuned customers) comes with Turbo & Tune. If you wait for sales it can be had for $2699.

If I were adventurous and live relatively close to a custom tuner then maybe I would get a custom tune, but the fact that APR has a pretty good tune and can be accessed from most shops is what would draw me more towards APR.

Good question. I was going to see what the cost of United Motorsports tune and a bit of dyno time would run, like Slowone has done.

But its my DD and riding the Ducati to work doesn't work well everyday. Also, from what I have read, the tune from APR is adequate. Got to ask Bluewater what they think.

If I read this post without the context of the discussion it's in, I would have thought you were talking about the frankenturbo. In fact I'd even bet that eurodyne's F23L tune would match up with and work better on this K04-R than a K04 file.

The wastegate setting on this turbo I bet will be lower than that of which on Frankenturbo. My guess is this due to the fact that JHM said it works great with APR software. All the logs that I've seen Frankenturbo on APR software the duty cycle is dropped to meet boost and avoid over shooting. If this is the case and JHM preload is set lower than that of Frankenturbo, I don't see it working to well with Eurodyne unless the PID maps are changed to accommodate the wastegate. And even then it still might not hit requested due to the wastegate door being blown open.

But i agree Eurodyne would be better for the Long haul and will achieve more power. For those looking to run this turbo with APR software I have a feeling that the results you'll get are going to be the same as there own K04 kit and no gains over.

I also will say that those saying Frankenturbo having poor quality, you are severely wrong. They even offer a two year warranty on the product. And you can get it ceramic coated as well. The quality is top notch and his customer service is by far better than any large competitor. A very stand up company. I was on the fence for years on Frankenturbo and I can say that all my worries with them have since changed.

All good points. And you can change wastegate preload with just springs, no?

And I've probably driven my car harder than most, with over 100 timeslips from the dragstrip in the 2 years I've been running the frankenturbo. It runs just as good as the day I installed it, and the owner of the company answers all my emails within 24 hours, even personally helping me pour over logs.

We also have a FMIC available ..

The wastegate preload could be adjusted by just tightening the actuator or installing a different one if the actuator isn't adjustable.

I am curious to see how this turbo pans out. But I still think the best turbo combo out there right now is frankenturbo/eurodyne.

What size is the compressor wheel on this Ko4-R turbo?

BOOM! I had been hedging on whether to take the K04 plunge or not for the longest. Going from stock, then APR Stage 1 within 3 months of purchasing it fresh off the delivery truck back in Dec. '09, then to Stage 2, the gains have been metered out well and has been a reliable DD now for 7+ years! The only caveat being that I've had to replace the stock turbo 3 TIMES, all for the same P2099 Low/no boost due to wastegate failure B.S! Two were covered under warranty. The third, I was already at near 100k, well outside their 70k extension for this very issue. Pleaded my case with my local dealership which was escalated to Audi North America, advocated hard for myself and managed to get them to agree on a Goodwill repair. Essentially, AoNA provided the replacement turbo, free of charge but I was on the hook for the install. Roughly 60/40 split which sure as hell was better than paying full boat!
Only regret was not going K04 then but, better late than never I suppose. Can't wait for Earrhythmic and others who go with the JHM turbo how it plays out before pulling the trigger.

[Jake@JHM]

On the B7 A4, we compared two cars with same hardware and tuning. One with an OEM S3 and the other with our K04-R. The K04-R hit much harder and pulled away on the top end.

Waste gate cracking pressure is set like an OEM S3, however waste gates are simple adjustments if you wanted to change it.

@poodini I'd sale you my k04 when CTS releases their kit

When you say 'hit much harder'

Do you mean the turbo spoiled quicker? Or just boost pressure was higher?

Also, what tuners are you guys going to be pairing this with anyway? I assume, as others noted, if we used APR software it would just provide regular K04 numbers.

I guess I'm asking if any tuners are going to calibrate specifically for the K04-R (or which you are planning to use)

[SleeperCar]

Because what I really want to know is.... E85 plus K04-R... I'll be the fastest?

[Jake@JHM]

Hit harder = boost comes in much quicker

We won't be pairing with anyone, but any competent Tuners OTS K04 software should work. Eventually we will have our own software for it for the B8.

We need something slightly larger than k04 and smaller than APRs EFR attempt. Something 400-425hp at the crank on 93 octane

Yea because it was designed to be a drop in replacement for a k03 maintaining OEM B7 locations as if it were a K03. The only thing that may not work right is the compressor housing to intercooler connection as it was designed for our B7 FMIC.

But sadly this would need a custom map from United or something since you guys don't offer any B8 software yet. Interesting to know though!

Its really an easy install. I did mine a few months ago in a little over an hour. All factory hoses fit just fine, no need for aftermarket hoses. I would suggest disconnecting the airbox(Heimholtz resonator) located on the driver side on the plastic charge pipe. Cap it off with a 1" chair leg cover and a hose clamp.
