VW (etc) 1.9 PD engine power question... - arnold2
Quick question - VW makes the 1.9 PD engine with a total of 6 outputs:
100 bhp
105 bhp
115 bhp
130 bhp
130 bhp & 230lb/ft torque
150 bhp

I think that's it !

What is actually the mechanical difference between them !

I know the 150 bhp in the Bora Sport (about to be replaced by the new Jetta) has a different turbo, but what about the others ? Do they use the same turbo, but have the engine management changed ? In that case everyone might as well buy the 100 bhp & have it chipped ... !

Makes the 90bhp from 2 litre HDi look a bit lame!

I think that there is a also a PD160 in one of the Seats.

The question is however what is the actual output. For instance PD130's fitted to 4WD Quattros and Passats have revised ECU settings and give around 145 bhp on a rolling road, nearer the PD150 than the other PD130's. In the same way 130 ps Mondeo's and X-Types give around 148 bhp on the rolling road.

Therefore there are in effect three different 130's in the Passat, 310nm torque, 320nm torque (6 speed Sport models) and 320nm torque 4WD.

The new HDI 2.0 gives 136ps, approx 133bhp claimed.

Makes 110 bhp from a 1580cc Peugeot/Citroen Hdi look quite good!

Chipping or remapping the ECU is a relatively cheap way of getting the extra bhp, unfortunately this doesn't improve the transmission, braking or handling of the car to cope with the extra power - higher output VAG diesel engined cars come with these improvements too. Many insurance companies are also not too keen on remapping, so increases in premiums may negate savings in buying a lower powered model and remapping it.

The new VAG 2.0 TDi engine has been taken to in excess of 250 bhp (from a 140 standard) with little modification apart from ECU reprogramming so expect this to be available in a variety of outputs too (already available with about 170 bhp in the new Passat).

There was a recent post on www.tdiclub.com asking the same thing. IIRC, for small changes its ECU tweaks only, but there are substantial mechanical differences between the 90bhp and 140bhp units. These include (again IIRC) crank, pistons, injectors, turbo and intercooler!
