Not long now..

Guy, I am wondering if I should get the highline TDI and tune it or wait for the GTD. so with that in mind, is it worth tuning a highline TDI and chipping the engine? Will its power output exceed the GTD? Will a tuned GTD output more than the TDI?

Considering what happened between the mk5 and mk6 twincharge tunes, those turned out to be the same. So would it be safe to assume a tuned GTD may well be the same or very little over a tuned TDI?

Ps if I go for a TDI will have to update my nick :p

Tuned tdi's give similar power and torque to standard mk5 & 6 GTD's, though it appears the mk7 GTD will have an extra 10 kw over the current model (more info here: Mk7 Golf GTD gets 135kW )

I think you need to bare in mind that the GTD is not simply a tdi with more power and torque, there are further refinements to the package (both mechanical and cosmetic) which make the car more suited to the powerplant.

Edit: A tuned GTD will certainly make more power than a tuned tdi.

This. The GTD and TDI engines are not mechanically identical with a different factory tune; the GTD will likely have a larger turbocharger, strengthened internals, etc etc.

If you're looking for performance and can wait till (at least) the end of the year, you should wait.

Not sure if there is any release date on the GTD yet?

[OilBurna]

slight correction it was also in the 103kw PD engine....

Should be around the same time as the GTI.

No GTD coming at this stage - its been canned.

Picked ours up this afternoon - you can see some big improvements over the MK6 and also some cost cutting in some places. Interior is a great improvement (evolution). Suspension is radically changed. DSG software has evolved, aerodynamics & underfloor stuff has improved well too.

Electronics are brilliant, Nav system makes the RNS510 look like a 386 PC.

Who wants to bet how much power a 100kw TDI puts out at the hubs on the dyno? 20km's on it - will know in an hour or so.

No air to air intercooler on the 110 TDI highline, it relies on a water / air version that shares radiator / engine coolant. Different DPF design again.

Keep us posted - sounds like there will be quite a few disappointed diesel guys who might need to look at a tuned TDI if they want to hit up mk7. Or look for a used mk6 GTD..

Well true to current VW form (since the introduction of the MK6), this car makes considerably more horsepower & torque than VW advertise. Over multiple consecutive dyno pulls it makes 109kw & 319nm at the hubs. You could factor in around 10 - 15% loss through the drivetrain. Now this car has 25kms only on it, so it may even loosen up a little and make more than that.

Surprisingly the air to water intercooler system worked really well & we see virtually no power drop off over 6 runs.

What I will do is overlay stock vs stock MK6 GTD on Monday when I power up the dyno.

You can feel an enormous difference in the weight split & newer engine location vs front suspension already, and chassis stiffness improvement is most apparent over the 6.

Source for the cancellation of GTD in Oz? Very hard to believe given success of MK6 GTD in RH markets such as UK and Oz (and LH ie Europe)
