Say Hello to the APR TT RS

[Poverty]

Its a development map, wait for the final version.

Over 415 hp from 5000rpm all the way to 7000rpm. Peak is at 6000rpm

peak torque from 3750rpm to 4750rpm

That free-flowing exhaust is surely helping. I still have the main 400 CPI cats on. I have peak power at 5980rpm and then it starts to decrease slowly. Torque is max at 2770, and I like it when torque is high low down, between 3400 and 5100 I have stable 550-570nm then it starts to decrease linearly, at 6400 I have 460nm.

Post up some plots guys. Development or not, its all good to see the progress.

Old skool here, VR6-T, time for you guys to catch up...

[MitchyRS]

Arin,

Do you have costings for any of this kit? Will it be an off the shelf item that can be bought and then tuned by any tuner or is it strictly APR?

What stage is the kit at now and what are we waiting on before it's complete? Can I buy the turbo off of you now and mate it to my existing hardware? what price range are we looking at for the turbo? $2-3k or more? Im across in the US in June, might bring back 1 of these in my suitcase

[NoPasaran]

OBviously you did not read about bespoke intake manifold and bespoke downpipe....

Why don't you buy a turbine yourself and just mate it? APR will probably use one of Garrett turbines...

[Arin@APR]

The turbocharger system will be sold as an entire kit including everything down to software, coolant and oil. I don't have an ETA yet.

With other word's very expensive.

Probably - yes, but noone forces you to buy it.

Not the answer I was hoping for but I do understand you guys need to recoup your cost of this R&D and keep it as an APR exclusive but its the old argument of low volume high value sales (Full APR kit) vs high volume low value (off the shelf, individual units, open to masses)

I dont want the full kit, I only want a turbo unit to bolt into place so that my standard intake and my standard downpipe mate upto it. Isn't this the stage your car is at now? Why cant you offer this?

Not everyone wants 600whp+ and the added stress on reliability. 450-500whp would do me just fine.

Keep up the good work though

[Poverty]

Mate, you can't just take the turbo and manifold and expect it to mate on to the rest of your OE system, you need to other hardware bits that APR are developing which will utilise the stock exhaust and intake anyway, and you will be needing the APR fuelling upgrade also as a BT kit will be pretty much limp wristed without it.

There is no cheap way of going BT, especially not of you want it to last, which this kit will.

Also on the reliability side of things that people keep talking about, I've got friends who are pushing 450-750hp from 1.8t's and 2.0t daily with no issue. Those cars get a kicking nearly every weekend, and they are fine. We will be using better hardware than my mates, plus we have more capacity and a extra cylinder. Reliability isn't a concern for me at all.

Just need someone to make a uprated clutch now...

[Arin@APR]

Hey guys, guess what we just released!

North American TT RS software has finally landed!!!

[AppleChilli]

^^^Great news; any word on when the exhaust will be available?

It's looking like it will be available right around the same time the dealer tools come out.

[michalborz]

I would get it if was like any other APR tune for 599 $. what makes TTRS so special that have to be 899$

A significant investment on our end into creating new ECU flashing tools and processess to access and crack into the ECU.

[Marty]

Man... this thing is pretty big. It took quite a bit of engineering to make it fit into such as small spot! :-)

Thank you for sharing these! Love the prototype and CAD shots. Any updates on this setup?

What makes the TT-RS so special, they charge 60K+?

[Arin@APR]

We have it on the car running already. The motors coming out for more modeling.... I'll grap some pix if I can.

[R5T]

It's look like that if we are lucky we can order a kit for Christmas.

I thought you were going to trade your RS for a GTR anyway.

Yep, being sarcastic .

Well TT-S with Prestige package and nav Is not far off 60K

[R5T]

The 2.5TFSI 5 cylinder engine.

Here are more development prototype pieces which are being sent out to another one of our development vehicles. We'll have test vehicles on several different continents all at once to ensure this kit and software is ready for left/right hand drive vehicles, high/low altitude, hot/cold weather, humid/dry weather, and the abuse of a few of the more crazy drivers out there. : )

APR T3 Investment Cast Inconel Exhaust Manifold.

The runner lengths were adjusted properly so each incoming pulse arrives at the turbocharger collector without colliding into each other. This promotes turbocharger spool just like people see with weaker and louder tubular manifolds.







APR Cast Turbo Inlet Pipe. This cast piece will bolt up to the OEM intake location allowing any intake on the market to connect at the same location. It also reuses all the OEM connection points for PCV evap and vacuum. The piece bolted to the turbo and uses a gasket for a clean and easy leak free install.







APR Investment Cast Turbo Downturn with divorced wastegate routing, internal exhaust gas scavenging promoters and v-band downpipe connection flange.







Garrett GTX Ball Bearing T3 Turbocharger with integrated divorced wastegate housing, billet compressor wheel and anti surge compressor housing. We are in the process of testing small to large GTX T3 frame turbochargers. This particular unit is a GTX3071 and we have GTX3076 and GTX35 turbos as well.









APR Prototype Turbocharger System. Shown here are ONLY a few of the cast parts. Our turbocharger systems include all software, fueling, gaskets, oil/coolant lines, heat shields, nuts, bolts, oil and coolant you need to install the kit and go.



We'll give more updates as we have them!

[jmh2002]

WOW!!! Im HGP Turbo on my VR6 so I can appreciate the investment that is going into all these proprietary APR parts (and I note some similarities in concept )

Well done

This will be not for the budget conscious, but for the quality conscious what an option to have available

[michalborz]

Can I be the lucky one to test this on my RS this looks preatty!!!

[Marty]

We'll give more updates as we have them!

Amazing work! Kudos to you guys for investing in the engineering of these high-quality parts.

What are the plans for fueling? New injectors needed? New pump needed?

[Arin@APR]

Injectors and pump. Already in development.

Sweet. How about the intercooler? Please tell me that stock is just fine for stage 3.

The parts really look like state of the art.

[Arin@APR]

Thank you! I'm sure our designers are happy to see comments like these.

[R5T]

Thank you! I'm sure our designers are happy to see comments like these.

btw, what power rage will those 3 turbo's have.
Or will it more in the line of different power and torque @ different rpm's. ???
So less power more torque ratio, even torque and power ratio and high power less torque ratio.

Well, I'm really not sure quite yet because we haven't tried everything.

Here's things to consider:

1. We want it to spool quickly.
2. We want good top end power.
3. We want an excellent driving experience.
4. We want it to be safe (fuel/knock/EGT).

A smaller turbo will spool quickly but may be out of steam towards redline.

A bigger turbo will spool slower but will have more steam towards redline.

We may run into a fueling limitation thus limiting the turbo size to something smaller.

We may run into a knock limitation thus limiting the turbo size to something smaller.

We may run into an EGT limitation thus limiting the turbo size or power output to something smaller or lower than what's theoretically possible to produce.

So it will come down to playing with each setup to find the best answer. We have our engineering tools which tell us what it should be, but experimentation will help with the "driving experience" aspect.

[R5T]

So at the end there will be one (the best) solution that will go on the market.
