Why is the idle so high? Is that a setting you've chosen on your standalone ECU or is it what your engine is doing on its own?

It was so high because of the Light crankshaft+yust 10 kg flywheel with clutch and secondary the sharp cams.

i think he said, that rpm is so high because of his aggressive cams..

Interesting thing, my first Setup wos with a lighter crankshaft ~18kg and Light Front pulley instead of vibration damper and i dont get idle under ~1600rmp.
By my new oem tdi crankshaft and littlebit lighter vibration damper get it down to ~ 1200rmp.
What a littlebit weight (3-4kg) can make.

Tomorrow i go at a dyno [emoji1]

dont have all the 5 cil diesel engines already not a higher gear setup in oilpump?
or did you just place a petrol oilpump on your engine ?

No the have the same gears. Is Use a Diesel one.


Also 2.8l v6 Petrol engine have the same sice of gears in diameter, but they are smaller. Yust 9 mm thick ( s2 have 11mm).

Tell us about the bigger gears in the oil pump. Why? You get a lot done fast!

I am think that the original pump bring not enough oil at higher rmp and Hot oil.

Make everything i can do.

Next step are bigger Gears in the oem oilpump and install the Golf shifter.
But first put it on a dyno and look how the hole setup works on the street. And see if the last 2 Years of work was the right way.

Looks like a well thought out engine to me, hopefully it lasts this time

And additional cooling for Front and back from head. Let a separate pump run above 85°.

Brand new oil pump from Audi. Oil pressure is over 4 bar when about 2k rpm. It's just the Tdi squirters flow lots at idle and cause lower oil pressure. I have no problems with that. Rule of thumb is 10 psi per 1k rpm on lots of engines.

I'm running Tdi squirters in my stroker in the Urs4. I have just over 1 bar at idle when oil is hot but it isn't a problem. Stock 3b oil pump. I have good oil pressure over 2k rpm when boost is made.

How old is your oil pump?
By the older Pumps the spring from the pressure relief valve get shorter and you have less pressure.
My idle is ~1600rmp, engine dont Run less than this. So i dont now the pressure at low rmp [emoji23]
