There is a guy called Manjit Saggu on Facebook has been working on releasing a bit more power, together with some Rover 75V8 and ZT260 owners on the Two-Sixties Forum. Larger throttle body, intake "smoothing", EGR mods etc. in the direction of 300, I hear.

Just a T4 won't help you much in that regard, but KMaps may be able to help, at a price (over £600?), but then stating only "+10%" on bhp. Probably at the wrong end of the rpm spectrum to help an auto Rover 75 V8 much anyway.

Real increases up to 400 or even 500 bhp and beyond, are in the realm of the superchargers. No one thinks that supercharging the auto Rover 75V8 is a good idea, or even a practical possibility as far as I know. Many include Dreadnought who converted many ZT 260's to over 400 bhp using the Kenne Bell supercharger, looked at it but finally discounted it. The very few MGR factory supercharged engines (and 1 car) made, were for manual MG's, not auto box Rovers, (Roush supercharged, mostly 385bhp). Production never got underway before the crash.

The DTM race modified cars were 520 bhp IIRC, and the land speed record ZT-T, normally aspirated, but with a very special engine, was 765bhp (for sale, if you would like the ultimate shopping car!).

David was the estate that had the runs on the salt planes not a 7.2 Litre or is my old brain not working? Also do you know if MGs estate still hold the record? I seem to remember Audi trying to capture it at one time.
Can anybody shed light on what holds the record today and for how long MG held it for?
