Audi S4/S5 B9 Hybrid Turbo List

[Kondax]

Thought I'd compile a list of hybrid turbos available for the S4/S5 B9. Let me know if there's any others available and I'll add them to the list.

Silly Rabbit Motorsports: SRM GTX3582R Gen 2

As of now I believe the SRM is the largest offering with Pure closely behind. Artek also have similar sized Hybrids.
Turbo Systems comes in second with TTE and Venom close behind.
Weistec do not alter the stock housing, the chra is the stock size.

I haven't got much information on the Artek Hybrid but I believe it's comparable to the SRM / Pure offerings. Although they aren't much use to most of us it's still good to have a full compilation of turbo offerings. I believe you have to contact them directly if you're interested in their Hybrid.

In regards to the Turbo Systems offering there are a few dealers selling the turbos, namely DMT Racing also. I have chosen to link EMD as they provide legitimate numbers and not just a power claim without any evidence.

If anybody is running one of the above turbos it would be great to hear your feedback.

I'm currently running the SRM GTX3582R without WMI, 25psi @ 6000 - 6500. Haven't got any dragy slips yet but hopefully will grab some during the Summer.

Have you dyno'd? I've been interested going Hybrid but I have no desire running WMI

[Kondax]

I haven't. Been waiting on fueling options / a tune before doing that. I'd estimate somewhere in 530-550 crank range but I could be wrong.

[Auddiss]

Very interested in what gains are on a tuned car.

[George@BMS]

Add Artek Motorsport from China. They good good results with their turbo.


I wouldnt put which ones rank how etc. Turbos are far more complex than wheel size. I would rather look at results at various boost levels. Typically compressor only turbos do not do much so look out for what work has been done on the exhaust side. Generally manufacturers will cut back the exhaust wheel and fit a bigger compressor wheel. Pure and SRM are the full monty.

Thanks for the recommendation, I'll add them to the list.

That info is also good. Apologies, I wasn't meaning to rank their capabilities based on the compressor size - just wanted something to pad up the post a bit hah.

Any thoughts on the KolbenKraft-Tuning one?

Thread here: https://www.audizine.com/forum/showt...Tuning-Germany

Is it even available anymore?

Only for the 2.0T, no?

Where are people getting their “core” turbos or an original factory turbo?

I have a core for sale, it’s posted in the classified section. Brand new squeaky clean!

[electron bom]

If you don't want to use the OEM turbo from your car for the core, you can source one on ebay. There are many available from Hungarian or German sellers for $500-$700.

[Sturn992]

Thank you

[Tony@EPL]

We're looking forward to trying a few more of the turbo's listed above. So far our testing has been limited to the SRM3582 and is showing very positive early results.

I was going to ask your thoughts about the turbo options. The SRM GTX hybrid is the largest out of all the options, as far as I can tell it is the only one using a full-size off the shelf bb chra. The others are modified or proprietary in some way and use existing stock lines. I get the feeling it won't get any better as a hybrid option than the gtx 3582 unless quicker response (or cheaper price) is the preference at 4700$ without core, it is quite pricey.

Do you know what timeframe we're looking at for the GTX, realistically? Couple of months?

Probably not what you want to hear, but US calibrations could be released this week. Rest of world will be a ways off.

Right now its the only turbo we have experience with. Stating the obvious it makes the car considerably faster, but at the cost of lower RPM grunt. This can obviously be offset with high shift points but I would imagine (my opinion and I havent even driven the car) it takes away some of what is so fun about this car (full boost/tq at ~2000-2100 rpm).

We are exploring options with the turbo builder we've used on our Porsche hybrids to hopefully find a "middle" ground option.

Ah bummer. Thanks

Did you run meth with your TTE5XX build? I was checking out their site and would have thought the dragy numbers would be better. Just curious if temps were holding you back or what

Rogier doesn't run meth, no.

[BrockDM]

Rogier doesn't run meth, no.

Thanks man. Looking back at it, 11.3 @ ~121mph with no meth is pretty solid for 93 octane. Stoked to see what the 7XX will do

I'm interested in seeing how far he can push it before more fueling is required - I don't think I'd be able to get those times on my SRM without a tune due to lack of fuel.

[1nS4ne]

I know the SRM GTX3582R is larger and they state it has ~1000RPM more lag than the OEM, but double the output. I am not a track star and I rarely go to the drag strip, most of my time behind the wheel is on the street, so is there an option among those listed above that increases power potential, but doesn't increase lag over OEM?

You're better off with the TTE5XX or Turbo Systems Stage 1. You won't make as much power (top 400, maybe low 500), but it will have less lag compared to the other larger offerings.

Its more like 1400-1500 rpm from the testing that we've done. That said, it MOVES once it gets going.

We haven't worked with either of these turbos... we are looking to produce files for both. Please email us if your interested.

[Drawblood]

Pure get's my vote. They make great stuff! Thanks for putting together this list Kondax. There's several I didn't know about.

This is exactly what I am struggling with making a decision on my Turbo Path - I have decided to go with Turbo Systems personally. I am sure everyone's offerings are great but they tick off the right boxes for me.

As Tony noted above our stock setup hits max Boost/TQ @ 2100 - with EPL tune I have super fun torque driven pull at virtually every range possible

Turbo Systems Stage 1 hits max TQ at 3200 though I don't know where it is sitting TQ/Boost wise at 2100 for relative reference and same with their new Stage 2
Their Stage 2 offering (has hit 719 Crank and 600awhp so far that I know on 2 vehicles) peaks TQ at 4200.

I am having trouble deciding what to do because as much as I want to have a solid strong 10 second car - I would hate to turn the amazing low and mid range torque monster that EPL has put together for me into something that only wakes up in the last part of the RPM Range and heavy throttle but then takes off like a rocket.
Unless we can safely take this engine out to 7-7500RPM on launches with the big turbo I think it might just change the car too much for what I want - but then again...compared to some other platform setups is their stage 2 even really that big ?


Really wish we had some feedback on more of these altogether - Such a hard choice!!

[Kondax]

To be honest unless you're running meth you won't get mid 10s even with the big turbos. Possibly high 10s on E85 but that's it.

Always going to be a case of wanting to chase more power - just depends how much money you want to put in the car.

[Auditude437]

When do you guys think the EPL tune is going to come out for the SRM turbo?

[Kondax]

They're currently testing it with a few people! I'm hoping to get on it soon once they offer it to me in the UK.

[East_Coast_S4]

They have maps already going for both Pure and SRM.
I'll be testing out one of the turbo systems options with them too relatively soon.

Which turbo?

[East_Coast_S4]

Read above, I can't decide if I want stage 1 or 2 yet.
About 1k RPM difference in power swing but 100-150 more HP
I'll be searching the webs for more insight from people using them outside US in next couple weeks.

My DP finally comes in 17th so I'll run that setup for a couple weeks first anyway.

Any turbo you decide on, EPL will be able to get you running right.

Still waiting on CTS to release their hybrid turbo based on the GTX3582R.

[nicotino15]

Turbo Systems has a stage 2 turbo with 60/74mm compressor side, and it looks like TTE is marketing their TTE710 which has a 66mm inlet, but not sure of the compressor exducer size. Anybody have specs for the other options so we can better compare the options? Most don't market turbine side, but we could at least compare compressor side and characteristics i.e. ball bearing, journal bearing.
