As predicted by some forum members, the 170ps. & 177ft.lb torque TDI engine is coming. The model it will be fitted in will be called Golf GT. Interestingly the above figures come from just a 1400cc 4cyl motor. but aided with both a turbo and supercharger. A strange combination but a weight saving engine block will help the power to weight ratio. Well folks, what next after the V10 TDI & this new configuration? A Formula 1 diesel car! Who knows.
New TDI engine on its way!

There are two GT spec engines the 1.4 TSI 170 (petrol) which is the twin charger and the 170 TDI. Its featured in this months VW Driver. I really don't know which I would choose as both are going to be amazing engines.Mmmm, pretty sure the 1.4 'TSI' twin charged engine is petrol powered mate..... 177ft.lb would be pretty woeful seeing as my PD130 has got 236ft.lb as standard...., but i could be wrong as i'm frequently told so by my missus...lol!! []
agreed, should think the torque is more like 377lb/ft really!Mmmm, pretty sure the 1.4 'TSI' twin charged engine is petrol powered mate..... 177ft.lb would be pretty woeful seeing as my PD130 has got 236ft.lb as standard...., but i could be wrong as i'm frequently told so by my missus...lol!! [

performance figures and comparisions to new GTI or older PD 150 model?
Thanks!

The new Passat Tdi 140 already has the PPD (Piezo-Pumpe-Duse) injector technology, and a new ECU to go with it.
We (me included) are just awaiting news of the launch date for the PPD170 engine in the Passat and Golf.
Which ever car has it first will be tested immediately by the 'tuning houses' to see if the usual 30-40bhp margins are still available to exploited by a remap.
The thoughts so far are that it's likely to be the same lump as the PD140 / PPD140, same turbo too, therefor making it highly probable that it's a "breathed-on" 140 bhp setup.

So, if I read you correctly, if it really is the case that this is just a breathed on 140, then the 40bhp margin shouldnt be available right? As I understood it, it was always the turbo that was the limiting factor with the existing 140 and not the fuel delivery, therefore the alterations in fuel delivery (Piezos) shouldnt make too much difference?
Well, the 170hp TDI will most likely not have the same turbo as 140. As
the PD130 and 140 share the same turbo, even the PD150 has a bigger
unit. Why would they downgrade from beefier 150 engine?
IMHO: Its just not possible to push the amount of fuel required for
170hp with the air available from smaller turbo, atleast not without a
lot of smoke and reliability issues in mass production.
Maybe someone can search ETKA if it already has info on this new engine?

Yeah but they wouldnt be downgrading would they? They've already stopped using the larger turbo thats in the old MK4 150 in favour of the unit on the Mk5. Therefore its just expanding on whats already there. The change in fuel delivery system is likely to see a smoother map with the increased precision of the delivery system. I dont think they'd change the turbo when its been proven that the current setup is good for a reliable 190bhp with nothing more than a remap.

Mate - i'm on tenterhooks over this......if the 170 has a bigger blower and sufficient capacity injectors, my destiny is already determined !
My buddies at a top tuning house are already sitting with a modded PPD ECU map in their possession - so it's all systems GO if it works out.

So they dont use the bigger turbo from 150 in the 140 engine, its not a
huge suprise really. The power is down with more capacity in the engine
and also 16V technology. Why would they use a bigger if the smaller
delivers enough air.
Reliable 190bhp with the current setup? Is it realible enough for VW? I dont think so.
