Hi everyone!
I am from Gabon ( in the central region of Africa). I recently got interested in collecting a few 60 series, diesel so far (2H, 12H-T engines).
I have driven a couple of 2Hs and 12H-Ts at full speed, or at least I pushed them as fast as I could on the highway, but I have noticed, they would very rarely go beyond 100 Kmh (62.14 mph).
I must confess the 12H-T engines had the turbo removed by the previous owners, but still, they were able to go up to 70/80 mph sometimes, after much effort.
Well, I know that as old-school (underpowered-as-per-modern standards) engines, they are slow to get up to speed, but
1) why does the needle on the speedo always seems to stabilize around 60/70/80 mph while the dial ( I guess that is the right name) indicates up to 100 (2H) or 110 (12-T)?
2) Is it because most of these engines have more or less 300,000 mileage on the clock (plus probably poor maintenance history), and could they do better after a rebuild or turbo install?
3) Or is it that in some parts of the world these cars came with factory speed-limitation "modifications" that a mechanic can or cannot fix? (I saw a few vids on Youtube where these engines could a bit more easily go beyond 80 mph.
Thanks in advance for your enlightenment
Regards
