**TTRS** Project 750hp
- Thread starter poverty
- Start date
Thanks guys.
Maybe a change of plans on the turbo front, we'll see.
In the meantime I bought a new headunit to replace the concert one.

Some more pics. The turbo is bigger than my mates meatball head lol.

+1. Nice project. Done a few large BHP evo builds, so this will be good to view in comparison.
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

1x S3 and 3x Fiestas.
I was telling my friend about this thread, and he said to me 'Is his user name poverty?'. You might remember him back when you both had K1's and I can even remember seeing the picture of 3 K1's in a row at the services when he collected some engine goodies from you.
So the car is being put back together now. Then off to get the ext wastegate and downpipes fabricated. I decided to not run a screamer pipe but instead have it routed back into the exhaust.

looks good, no video of it running is going to do this breast justice.
top work. how much did customs sting you to clear?

No idea on customs charges, APR have imported it in.
Still waiting on delivery of my twin plate clutch
Still waiting on delivery of my twin plate clutch
UPDATE:
Decided on some hardware changes.
The turbokit got removed and sent off for a special coating.
APR released their own intercooler which has the biggest frontal area off all TTRS intercoolers so I have ordered one of those aswell.
And finally, a carbon carbon clutch is being developed so Im going to upgrade to that when its released also.
Heres some data and info on the APR intercooler.
Product Page
The APR Intercooler System dramatically lowers charge air temperature and resists heat soak far better the TT RSâs factory intercooler system. Through a massively increased frontal surface area, superior intercooler core design and smooth, cast end tanks, APRâs 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.
Intercooler Ambient Air Fins
Each unit uses a high quality, bar and plate core with staggered and louvered fins. The Intercoolerâs 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 coreâs 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 intercoolerâs 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. APRâs 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 barâs 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 RSâs massive grille. The black chip and corrosion resistant coating does not alter the thermal effectiveness of the intercooler core. During testing APRâs 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.

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 Intercoolerâs 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
APRâs Engineers set out to further prove each Intercoolerâs 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 APRâs ECU Explorer data logging suite. While APRâs 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.

poverty this is a truly impressive thread and to think I'd missed this until now! True dedication to making a quite unique TTRS and those parts are works of art in themselves. I think this thread is what the word awe was created for. I'm guessing the driving experience is equally impressive!
Time for an update, car was meant to have been ready by now but ran into some slight difficulties.
But my good friend jonnys car was ready and he got some figures off his.
660hp on v-power
0-60 in 2.8
100-200km/h in 5.8
1/4 mile in 10.7 @ 136mph
And here's some videos. Yes, it's a manual

Absolute monster!!! The numbers are unbelievable. When it goes like that just watch and be amazed haha.
Sounded like a deisel on idle, but that launch and those gear changes.... Fair play

the cars are identical spec except for valvetrain!
really can't wait to get mine, gonna take a while to get used to it I think,last time I drove anything fast was my mates 650hp 911 turbo which I thought at the time was perhaps too fast for public road use, and now we have two TT's here which are quite a bit faster!
