306 2.0 hdi 16v

[dashmader]

--Well i have been driving the car a bit now and made like 2000 KM on road.

-- Diferences that i noticed on this 16v engine:

Good things

-- It seems more economic
-- less noisy
-- smooth driving through the gears
-- on iddle less vibration
-- water temperature is a lot less, dont know why. 8v was always on 80º and a bit more, this 16v is always on 70º/71º no more then that, confirmed on PP2000.
-- i am runing same rail pressure, but with R70 pump, same IQ 95mm^3 and 1.4 bar turbo, but i this engine makes more smoke with same boost and IQ, a bit more, WHY???
-- Power is almost the same, i think no more and no less. but it makes more smoke.

Any thoughts about the increase in smoke?? do this 16v engine needs more air??
