Yes please, as many rpm-boost data points as you can get. It might be some-time before mine is road-worthy.

There was a mob in Perth that was changing the original compressor to a better designed one from another model,I'm sure someone on here had it done as they found as you have that the originals not that good. Pat

We get ~8L/100 for normal driving and recently did 1000km towing a 5m boat at sub 10L/100.

I can buy you some dark glasses and a hat if it's so painfull to be seen in a Tdi Pat

One more question Dougal,why can't a super charger be fitted to a diesel?. Pat

I think the compressor is fine. It's the turbine side that is best improved. But compounds can bypass most of that with other benefits at the same time.

Because diesels need boost tied to load. Superchargers are a huge parasitic draw and their compression isn't very efficient. Also without the effect of vapourising petrol cooling the charge they are close to useless.

Found the dyno of my engine, soon after I had gas added. You will see the changes as you scan the graphs .....
The blue line is in fact Diesel only... then the others are both with gas.

Mmm 500Nm of torque.

Seems legit.

In low range.
