Golf GTD MK6 big turbo build

turbo johan · Sep 22, 2011

I build a big turbo on a 2.0 CR170 engine lately.
Car makes 253 hp and 470 Nm now.
Mods; manifold, turbo, bigger ic, 2,5" turboback exhaust w/o DPF and sw.
Some pictures:

We also do time attack series with this car.
This car is 1st in the competition now (lowest class)

Great project Johan, It's nice to see big hp numbers of cr engines.

Greetings, Bernard

Nice, Cant wait to get stuck into the CR engines!!

Nice. I'm curious, what was the reasoning behind choosing a T series instead of a GT series turbo?

majesty78 · Sep 25, 2011

Its a GTB Turbo ;-)

Wow - that thing looks bone stock on the outside

Nice work.

Grede · Sep 26, 2011

looks nice, what about the fuel, are there any fuel left for more power or is it on the limit
or are bigger CR nozzles the next thing.

Last year there was an Euro 170HP TDI similar to this with GTB2260VK + exhaust only. It made 235bhp and torque was no less than 400Nm at 2300-4000 RPM. It was smoke-free with stock rail pressure and it still had a little bit of fuel left. If I squeeze in a little more fuel I'm not sure if it can make 260bhp without increasing rail pressure (it also depends on the dyno). The customer was happy as-is. Bigger tips are needed for much more power like 300bhp anyway.

Nice work, Johan!

Would the stock bottom end support 300 hp...?

The only way it should be

Thanks

I have still quite some fuel left.
My feeling says that it can support 300 hp quite easy.
Or is the problem the after injections?
I think airflow just quits at 250/260 hp.
More boost just doesn't work.

I think stock bottom end will hold 300 hp as long as you can keep it efficient.
Not to high egt, emp and pcp's and engine will survive quite some power.

I suppose the CR heads are more restrictive, especially the early ones.

enjoyminutemaid · Sep 27, 2011

Impressive numbers. What parts did you upgrade?

VeeDubTDI · Sep 27, 2011

Do you have any videos of this thing going? Cruise around town, dyno, track, etc.?

Hi Johan,

What about the pre compressor part? Maybe the intake diameters are too small, and what about the MAF ? Is it a 70mm one ?

mo_focus · Oct 6, 2011

Can the clutch handle all this power?

eddie_1 · Oct 7, 2011

Oranjeboom! What are the elasticity measurement numbers? 60-100kmh in 4th? 80-120kmh in 5th? Would be interesting to compare.

TDIfreak · Oct 8, 2011

Looks like pro stuff there

.
What about ESP, something special to get rid of it for racing?

Bojje · Oct 8, 2011

I've read that the new Golf GTD has some kind of "tone generator" that gives it a little gasoline engine sound. Since you've done the exhaust mods, how does the "tone generator" work, what is it?

mrchill · Oct 8, 2011

CR heads are REALLY restrictive...its amazing that they make power at all. I bet a serious port job would help a lot.

Ross74H · Oct 9, 2011

hum, where did you get the DPF delete from? wondering if it would be compatible with our 2009 CR170 Superb.

anne · Oct 10, 2011

pics from the car running on track during time attack

eddie_1 · Oct 10, 2011

How many Friesian cows are under the hood? Wow, that thing must be moving?

Bruce GT3 · Oct 14, 2011

Nice work Johan!!

Did you do all the desing and fab work yourself?

I have a 2010 CR170 Leon with the DPf-removed and Revo software. Still running very sweetly and still giving a good reliable 230hp and 460Nm. However, I would love to develop the car further, so a new turbo looks like the next thing on the shopping list!

Sorry for not being able to shut up, but 230hp/460Nm with just a tune and dpf delete? That's 22hp/25Nm more that Revo promises with their software... Smells of "UK numbers" a long way...

Sorry Alcaid,

...and a Revo custom map for the DPF-off...
