Stunning engine, far ahead of it's time, handling on a parr for the period (TR3 Chassis), later ones could stop as they had discs. Went very well as it was 140 BHP and body although heavy was advanced being GRP.
Finally being picky no such thing as Daimler Dart it's an SP250 Sports as Dart was trade marked in the US. So the fantasy needs correcting Pauline!
There must be a link between motorboating and Daimler SP250's, as I maintain that the day I give up the sound of a V8 boat engine for rags and sticks I will have get therapy from the daimler V8.
Was it really such a good V8?
I've never driven one but remember the assessments of it in the Mark2 jag body ? called the Daimler V8 250. It was said to be smooth but short of torque (polite words for those days meaning gutless) and was horrendously thirsty. OK it was auto only as I remember but it was slower and more thirsty than the 3.8 Jag engine. I doubt if they would have sold any if they costed it correctly. It was not an especially simple engine standard pushrods and 2 SU whereas the XK twin ohc 2-3 SU was probably fully amortised by then.
The engine was designed by Edward Turner who did most Triumph Motor bike engines amongst a plethora of other things. It was a 2.5L hemi headed v8 with alloy heads and a single cam, a chinese copy of 4.5L was put in the Daimler Century or Conquest (I can never remember). Most people compare the Mk2 shape 250 with a 3.8 whereas it was faster and more economical than the 2.4, given an equivalent box. Most of the sour grapes was generated by the not invented here brigade who didn't want the competition.
Having owned and worked on both, the Daimler is a darn sight easier than a Jag 6!
Final point is Russ Carpenter tuned a 2.5 V8 to give over 1100BHP in his drag racer!
