If you calculate the effective ratios on the current plus 4 they are not very different to that one and everyone seems happy with the current one.
Not happy with it, too long, and with the new speed limitation at 80 km/h in France, 2000 rpm and 45 bhp with 5th gear is difficult to use. I like that a motor spins at less 50% of its max rev. At this speed 2500 rpm with 4th gear and 59 bhp is also a bit low. My old Ford Puma with less power (125 bhp) and short ratios are a real pleasure, you can use the 5th at 70 km/h without problem and 3000 rpm at 90 km/h.

I fitted my 97 +4 with a Librands exhaust manifold. That freed up lots of torque in mid range & made it a more pleasurable drive.

Goes to show we are all different. The m16 plus 4 with John Worrall straight through exhaust was quite happy at 2000rpm and 50mph and as this corresponded to a resonance in the exhaust it made a wonderful noise when you squeezed the throttle to balance the car in a bend. The current one runs ok at 1000rpm and 30mph but needs 2 gears down if you want to do any more than creep to a faster speed from there so I don't do that often. Since I added an itg filter and cold air induction the acceleration from 50mph at about 2000rpm in 5th is pretty good, clearly if you are racing use 3rd.

Steven.
I had an 89 Plus four for a long time. Mark Adams worked on it in 2004 and, without changing mechanicals, found an extra 30bhp at the flywheel. This car would run to 70mph in second, 110 in third,had a lot of low down torque and returned 35 0r so around town. There is a discussion on the Rover Tech forum. If I can locate it I will pm it to you. If you can be bothered to remove the head on these engines, there is a load of cleaning-up of the casting to occupy your time and a dremmel to aid gas flow.

Lord Sward, like you I am 6ft 1in, 15 stone and arthritis in my knees. I have a 1998 T16 Plus4. Very happy with it, plenty of torque so great for relaxed cruising but also fun when at the top of the rev range. Easy to get in and out. BHM have one for sale at present I believe, I got mine from them great service.

Though sometimes problem with the left hand gear shifting. 1993 +4 RHD with Librands manifold and it feels quicker than my BMW 320d (7.7 sec)

Steven,
A bit late but I have just come across that article by LJK Setright in the Brooklands Portfolio 1968-2001 where he seems much more positive. I think the title is Anew heart for an old soul.
