**TTRS** Project 750hp



Lets see how close I can get to 750hp †


The story start in autumn 2010.

All my life I had wanted a UrQuattro or a turbocharged 5 cylinder audi, so when they announced the TTRS my prayers where answered.

So I went ahead and traded in my stage 2 plus, 360hp, 2.0TFSI Cupra K1.



Great car, practical, cheap to run, and looked the part for a young man! Loved the car, hated the dealer after support!

I then picked up this beauty, Ibis white, delivery miles, so happy! Dream come true.

First thing I did was to remove the license plate off the front. Looks much better!



TTRS_500

First mod obviously is a remap.

I got this done by Revo, and it bumped the car up to 400hp on stage 1.

I then added a full turbo back race exhaust from milltek.

Stock





Milltek vs oem


TTRS_500

Next I looked at the brakes. The OEM pads were very dusty and didnt last long at all.

I bought some brembo blues for the car.




In hindsight these werent a very good addition as the soon killed the admittely not very good stock rotors.

Next I changed the panel filter.







I then looked at the intercooler. The stock intercooler is tiny so I fitted a forge motorsport unit. I got it fitted at Forge HQ, got a chance to meet the big boss Peter who is a really nice guy and really enthusiastic about his products which was nice to see.









TTRS_500

At this point I will introduce my buddies roadster. We mod our cars together, so he also got the forge intercooler fitted at HQ the same day.

His spec then being identical to mine up at that point.




Both of us not being happy with our brakes, we turned our attention to calipers.

We both settled on a set of rs4/rs5/r8/gallardo 8 pot calipers.









We also bought some new braided brake lines, castrol SRF brake fluid and I bought mintex 1155 pads. A friend machined the "revo" plate for us so the pads would sit on the oem disc properly.



TTRS_500

Next up I attended a 30-130 and top speed event at a runway.

This was my best result. 30-130 in 14 secs, and 170mph top speed. Basically the same results as stock GTR on the day. Not bad for a manual 400hp TTRS.






After that it was show season, and the two TTRS attended a few! The TTRS also won a auto X, handling challenge type event at one of the shows, which surprised many as we thought the track would be more suited to a N.A super mini type car. As soon as the TT was on boost it was time to brake again, so a good and shock result.






TTRS_500

I then replaced the stock intercooler hoses for some uprated forge ones. Another great forge product!



However we then came across a THS intercooler for free, and we were wondering what we could do with it. So, we decided to cram it behind the roadsters engine bay somehow!

And so this is what we came up with. Removed the air conditioning rad, attempted to remove the A/C pump aswell, but thats required due to the way the belts run on the engine. For it to fit we also had to cut the crash bar.



Then we painted the intercooler black for the stealth look.







End results via logging shows that temps are even cooler, and will peak at a certain temp and not increase anymore, but if you ask me whether its worth massacaring your TTRS for the small gain over the forge unit, I would say no. Therefore the coupe wont be going this route, and it did highlight actually how well the forge unit is actually designed, as the temps differences were minimal!
TTRS_500



The roadster then got some new wheels, whilst the coupe got race plugs.



New vs old





Full polybush set for both cars

TTRS_500



Then I decided to ditch the milltek in favour of a scorpion turbo back titanium exhaust.
This exhaust is the most beautiful piece of engineering I have ever got to touch I must say. Work of art!

And the weight saving is awesome too, i could live the backbox with my two little fingers!





















It turns blue after getting hot!

TTRS_500

The roadster then got this prototype ITG intake! Made nice gains!



And we decided the roadster needed a louder exhaust that the milltek race back box.

So we fitted a single exit rear can! Now its really loud, sounds super!

TTRS_500

At this point it was decided that we would move away from Revo software, and paid a visit to APR.

They wrote a stage 2 map for the car, we were hoping for great things and we werent dissapointed. The power holding that the map provided vs the revo stage 2 map was just crazy. Its pulls and pulls all the way to the redline. The way the power doesnt drop off and it keeps on just pulling leaves you smiling from ear to ear.

Now after the forge intercooler was installed, the car was dynoed at 420hp at stage 2 and between 380-400lbft of torque, I cant remember the exact figure.

I decided I wanted to dyno this new map to see what the car was making now.





The APR map gave me a nice gain, 430hp and 450lbft! The power curve is just beautiful aswell!

So now we are at 430hp and just about reaching the limits of the stock turbo.

We still need more power.

To do this the car requires:

Uprated clutch
Uprated fuelling
Bigger turbo
Internals, because we are going over the 600/650hp threshold


So all of the above is in the works now.

Clutch spec has been decided on, it will be a twin plate, hopefully ready sooner than later
TTRS_500

Engines out!



TTRS_500

Some more exhaust porn shamelessy taken from jonnys thread. Gotta give massive props to Forge Motorsport/scorpion exhaust for making a Ti exhaust for the TTRS! Aero Space Grade 1 Titanium with 1mm thickness!













TTRS_500

And so the engine build has begun!







And this is where we are at now:


Stripped down head



Port moulds and the ferrea valevtrain



TTRS_500

Rings gapped, parts balanced, ready for assembly. High temp, low friction thermal coating.


Old VS new

That's johhny's apr development car I wonder how much of his build has been subsidised? Good times trap speed shows its making strong power
TTRS_500

I saw jonny earlier today actually, he says the car has loads more in it still had a slight running issue on the day so looking forward to see what times he and the car makes next time round.

Might be worthwhile me to mention that I wouldn't be where I am now with this build if it wasn't for jonny, never done this sort of thing before so always asking him for advice and he has helped put me in touch with the right people!
TTRS_500

Right, engines done this week, then moving onto the next stage of refitting it back inside the car and running it in.

Ive also made some extra progress on the weight saving. These recaros are 13kg with sidemounts and runners. The OEM seats are about 34kg, so a saving of 21kg per seat.

The titanium exhaust saves 26kg over OEM.

So thats a 68kg saving so far. I have a few more weight saving ideas in my head, so should be able to reduce the weight by about 100kg over stock. Will make the car weigh roughly 1360kg with a quarter tank.

All coming together nicely Ja

Best of luck with this project mate

Race Developments, builders of the 700hp 2.0tfsi bonneville landspeed record holding skoda.

In a nutshell superfinishing removes the imperfections off moving parts, meaning less friction and up to 4 times longer component life. Extensively used by F1 and superbike race teams.

For greater detail heres a mag review of superfinishing

No, the bore was intact and free from damage, only damage was bent valves in the cylinder head, but nothing had broke off inside the engine.

Nice!

Is it Super expensive to have the parts Superfinsihed   ?
TTRS_500

I dont think its too expensive, im not sure on the price of the process alone.

Whatever it does cost though, the fact components have been proven withstand 30 percent higher loads for at least three times the life of the non superfinished part makes the outlay worthwhile imo

Indeed ! Looking forward to your results !
TTRS_500

**update**

Next immediate step right now is strengthning the gearbox.

So its being split open, and the gears etc will be superfinished.

The end results will look like this:

This is a great project

Thanks for taking the time to keep us posted.

Hope it all pays off and you get the result you want.
speedfr38ky

very interesting thread. enjoyable reading. If i ever drop the engine out of my c6 for a big turbo conversion ill get the gearbox and relevant engine parts superfinished. makes a lot of sense.
Glen_S4

Awsome Car... well both the Coupe & Cab.

Great Read to see some Top Quality Projects

Fantastic project and its good to see the pics and changes as it evolves.. keep it coming please

One (possibly bizarre) Question (from one of your first threads) ... How do you get away with running no front plate with PC Plod so active on ANPRS's these days ?  Are you just lucky and just never been stopped ?
S4Player

Turbo looks like a massive funny shaped hair dryer, great investment for a hairdresser obviously :p
Mule

Good thing to see that it begins to look like I said it should have looked from the beginning....

Its only taken a year and a half to get there and some engines and lost faces.....

But better late than never!

Now they just need a WG that can hold boost above 1,1 bar at 7500.....

I just keep the plate in the window, seems alot of ttrs owners these days run with no front plate.

At worst it s a 30 fine.

Thanks Simon, really cant wait, its been a while as you know!  
TTRS_500

Thanks guys, if all goes to plan, the car will be getting built sometime next week.

In the mean time ive bought a bigger intercooler. This is the forge race version, so bigger than their sport, and this time in black to go with the stealth look. Forge say they gained 50hp from these new intercooler over their sport version on the TTShops hybrid ttrs.

A friend of mine also on a hybrid turbo tuned by gained 40hp from fitting this intercooler and new mapping, so it only made sense for me to upgrade, and possibly I wont need to run WMI now

Heres the findings of my mate Alex on his car.

Results in from new Forge race intercooler on my TTRS

Got back yesterday after a long day at MRC, as some of you know I was having trouble with intake temps.

Starting both runs with a soild intake temp of 10C we saw that the stock cooler was going +65c so upto max 75c. With the forge race we were seeing the intake rise + 10c to + 15c so max 30c.

Very happy with it, nice piece of kit, well made.

Blue = stock cooler
Black = Forge race

Another great result there on the forge intercooler !

Im glad another great result as when was announced a 50hp+ gain with our turbo on TTshops car, there was few that doubted. †Explains why other LO500P cars without are not performing as well, as i said.

Not seen anything of these cars yet? Lost in the flooding?

I think they are ghosts.... Maybe they should call it TTRS Phantom MK3?

Let me repeat myself....

Where is the results? Hardware has been here since feb? Is the mapping equipment lost in the floods?

LMAO
TTRS_500

Made some changes on hardware spec. Hopefully have a carbon carbon clutch sooner than later.

Also ordered a new intercooler, will be the third one now.


Product Page



The APR Intercooler System dramatically lowers charge air temperature and resists heat soak far better the TT RSís factory intercooler system. Through a massively increased frontal surface area, superior intercooler core design and smooth, cast end tanks, APRís engineers were able to create an intercooler capable of supporting power levels well beyond that of the factory unit. Expect increased horsepower and torque and dramatically prolonged performance.


  • Dramatically lowers intake air temperature
  • Increases horesepower and torque while prolonging performance
  • APR intercooler core dimensions: 3.00" x 12.70" x 22.25"
  • OEM intercooler core dimensions 3.19" x 6.38x" x 21.75"
  • 104% more frontal area and 92% larger core compared to stock
  • Pressure tested for leak proof operation
  • Smooth cast alumnium end tanks
  • CNC machined hose connection points
  • Integrated light weight support brace, horn and sensor brackets
  • Stealthy black coating does not alter thermal effectiveness
  • Full install directions and APR's world-renowned customer support
  • Lifetime warranty


Intercooler Ambient Air Fins



Each unit uses a high quality, bar and plate core with staggered and louvered fins. The Intercoolerís exceptionally tall design and fin structure exposes the core to a greater volume of airflow than possible with the factory or similar aftermarket short and thick core designs. With more of the intercooler directly exposed to the elements, cooling effectiveness dramatically increases.

Intercooler Charge Air Fins



Internally, the APR Intercooler System features a staggered and louvered fin design with a core density chosen as a balance between cooling effectiveness and pressure drop. Due to the coreís massive volume, the balance was easily adjusted to favor minimal pressure drop while still providing superior effectiveness compared stock and similar to stock designs.

Intercooler Rear with Support Brace installed



The intercoolerís maximum size and frontal area is directly related to packaging constraints found at the front end of the vehicle. Intercooler units located in the factory location are design limited resulting in increased volume primarily through expanding the depth of the system. Unfortunately increasing depth only slightly increases the intercoolers effectiveness compared to increased frontal surface area. APRís Intercooler System includes a reengineered front-end support brace constructed from billet aluminum to maximize packaging constraints. The low profile support brace resides near the factory location and no longer blocks the intercooler from front-end airflow. The barís inner design features a weight saving grid, which also aids in airflow through the core.



The intercooler core and brace are both black to remain stealthy behind the TT RSís massive grille. The black chip and corrosion resistant coating does not alter the thermal effectiveness of the intercooler core. During testing APRís Engineers were unable to measure a difference in temperature between the coated and non-coated system during both dyno and road tests. This was further backed up with matching dyno performance between coated and uncoated systems equaling each other.



More Photos : Click to Enlarge



Testing Data - Dyno

The Test below demonstrates the intercoolers ability to cool intake air temperature even under brutal conditions. Six back-to-back pulls were preformed with absolutely no cool down between runs. The APR Intercoolerís first run was conducted in slightly worse conditions than the stock intercooler, but it was able to keep the intake air temperature at redline lower than stock even after the sixth back to back pull! The dramatic rise in temperature from the stock intercooler cost the TT RS valuable horsepower on the dyno and averaged over 25 HP less than the APR unit across the six runs.







Testing Data - Street

APRís Engineers set out to further prove each Intercoolerís effectiveness by testing in real world conditions on the street. Four back-to-back 20-130 mph pulls were conducted with both the factory and APR intercooler unit while various data points were collected with APRís ECU Explorer data logging suite. While APRís Engineers made every effort to keep starting temps identical between the two intercoolers, unfortunately conditions worsened while testing the APR unit as ambient temperature increased.

The rise in temperature was still no match for the APR intercooler unit. Pull after pull, the intercooler was able to cool charge air temperature below the actual starting temperature! The stock intercooler unfortunately experienced a rapid temperature increase and on average ran 14C higher than the starting temperature. The intake air temperature results collected on the street mimicked that of the data collected on the dyno further backing the power associated with each unit.

So your update is basically just promoting an APR intercooler then

Haha was easy to just copy and paste.

The turbo kit was removed from the engine for a special coating.

Other than that, it's nearly ready.

The car is so fast now, I'm over the moon with the result. Very responsive, and power everywhere.
stuartx

How did the power figure end up?
TTRS_500

It's not been dyno'd but going by the data logs and comparing to jonnyc's data logs, boost, timing, airflow, they are pretty much identical, and he dynod 660hp on a hub dyno. That number has been converted to flywheel btw.
TTRS_500

UPDATE:

Ive had the car back for a while now, but been too busy enjoying it in all my spare time. Its 97 percent complete I have been busy running in the engine motorsport style and generally getting used to it. It requires one last visit for the VWR air intake to be fitted and a general final nut and bolts check, including the loading of the final map.

We did have some valvetrain issues along the way, so ive gone back to stock audi valves and springs. Therefore technically APR consider the car to be stage 3 plus and not full blown stage 4. Valvetrain is something I might revist in the future once I have the time and money to get more development work done.

So the car hasnt been dynoed, but we know roughly what power the car is making from the data logs. Its a solid 650hp 650lbft car for sure, some reckon it could even be knocking on the door of 700hp. Whatever it is, its fast, and trying to put the power down when its cold and wet is a hard task. Ive had the car spinning its wheels in 4th, and even with ESP fully on ive had a one or two fishtail occasions where the car tries to throw you off the road just going WOT in a straight line. Needless to say I keep ESP fully on in these conditions. I tried it in ESP sport once, where the TC isnt as nannying, and even a slight application of the throttle in the boost range would mean sideway action.

So before at stage 2, where you would jump in the car in pretty much any weather condition and turn the ESP into sport or OFF was possible, now it no longer is if you want to do WOT applications.

So onto how it drives. Around town, just cruising, its pretty much like OEM, if we disregard the all round stiffer engine mounts I opted for and the SMF twin plate clutch as they are obviously noisier than OEM. I think most stage 3 customers only fit the lower gearbox mount, but I wanted the whole works.

The car feels more solid and communicative because of the mounts, blip the throttle and the revs fly up in the blink of an eye due to the lighter flywheel, and you get a racecar-ish "thrum" into the cabin.

The clutch took me a day or two to get used to, but it appears the more mileage I put on the car, the more OEM it gets. You do notice the weight of the race clutch if you keep it dipped in traffic, so you soon stop doing that and make use of neutral and the handbrake instead.

MPG is in the low 40's now on the motorway at a steady 70mph. One WOT scenario will drag the average right down though. It drinks when you put your foot down. Around town Id say its around the same as with a stock turbo.

Now how does it drive like in anger? Well it kicks, really really kicks hard. The car is responsive and the spool is quick, boost doesnt really build gradually like most big turbo cars ive experienced, it well just kicks in, and the ass end squats throwing you into the back of the seat. The throw into the seat back action is so intense, that once you come off boost you and your passenger will notice that the seatbelt has tightned around your body. People who are generally known to be good passengers, turn into not so good passengers, myself included.

The car pulls hard from 3k rpm all the way to the limiter, its relentless and it doesnt die off. Spool on my motor comes in like 700rpm earlier than that of stage 3 cars without the engine work. This is down to the work of racedevelopments, and I'll post more about that at another time in greater detail.

So all in all, very happy, the car has exceeded expectations, and the fact that its quicker in the 100-200km/h dash than a aventador, macca f1, pagani zonda F (with jonnyc behind the wheel) well thats just a bonus.

I'll carry on posting, about what the car is like to live with day to day, as people never really post about that side of things, so maybe it will be of interest to some people, who have flirted with the idea of a BT but have been unsure for whatever reason to see how others are getting on.
