Selle motor, maar net 2 pistons minder, het my TD27 baie beter geloop met net a surge tenk reg langs die filter. Die diesel pomp werk hard om net die diesel by homself te kry. Ek het die surge tenk ingesit saam pomp om verby die dikker kook olie te kom waarmee ek ry. Maar ek kon nie pompe kry wat kon oorleef met die kook olie wat so dik is nie. Hulle het skaars a uur gehou elk, voor hulle gekalf het.

Toe een dag, sien ek wat gebeur as jou olie teveel weerstand bied in die pyp van jou tenk af. -10 grade oggend in Parys met teveel kook olie teenoor Paraffin mix, en die gewone diesel pomp sluk sy seel op sy throttle shaft in, en suig en pomp dan genoeg lug deur die sisteem om jou pomp binne 60km op te vreet. Les geleer, maar soek nog steeds vir my die regte "skroef" tipe pomp om daie olie te pomp saam met a heat exchanger om die brandstof bietjie warm te maak om dit dunner te kry.

Maar ja, minder weerstand in die diesel pyp laat ons trokkies veel beter loop.

Ok Gents, finally I have done the dyno runs to see what the benefit is of installing the inline pump.

As mentioned earlier, the Facet pump is not up to the task to deliver fuel in a positive manner........ pun intended :lol:

The end product is a John Deere 90 series external pump which is pressure regulated just before the injection pump. I must say that the power delivery is very smooth and you can actually feel the power being better. Driveability is better and strangely enough, the engine is much more "quieter" if I dare to use that term for a TD42.

So here is the dyno graph after the inline pump was installed. Please note, the boost pressure and injection pump setup was left unchanged.
Stay tuned as I have done something else as well that helped the old man go a bit better.

Now here is where it got excited.

I imported a new turbo which got some very good reviews. It was not cheap but this test proved the point that some turbo's are more expensive for a reason.
I already had a very good Mitsubishi TD05 16G and replaced it with a 18G.
Delivering 1.4 bar of boost with a good turbo is not quite the same as delivering 1.4 bar of boost with a great turbo.

This dyno run I did in VERY hot conditions vs the previous run in very cool weather, so the gains will be more on a cooler day like the initial dyno run.
Once again, everything was left untouched except the turbo that was changed. Boost pressure was set to 1.4 bar just as before.

End Result is 164,7kw & 605.1Nm
That's a massive 16% gain in peak power just by upgrading the turbo!

Actually its a TD05 made by Arashi. Its not that well known, but it sure works fine. There are actually so much nice turbo's out there today but its not cheap at all
