Coming from a corsa 1.3 cdti (albeit remapped to 100bhp and a bit more torque) I would have thought going to a 330d (184bhp) would have been quite a big leap in performance but ive been left very underwhelmed.
I understand there is a big weight difference but there is also quite a big power difference so thought I would be in for a nice surprise.
I dont think there are any real problems with it (turbo working, no whooshing or leaking I dont think) but when off turbo the car just seems sluggish and even when engaging the turbo it seems to take a while for much to happen. (flat spots?).
Ive been looking to compare it with another similar car (performance wise) to see just what would happen and I have some feedback.
Trackday situation, straight road, my car standard as was other car (Renaultsport 172), rolling start from about 10mph.
Up to about 80 he pulled a good 5 lengths on me (changing gear at about 4k revs), 80-100 gap stayed the same, 100-110 I start reeling him in, near 125 im right on him, end of comparison.
Does the above sound about right or would you expect difference results? No wheelspin, no missed gears, everything was pretty much spot on.
