I found this picture on-line recently of a fuel injected 16-valve Sprint engine in a prototype SD2, which was ababdoned in 1975 or 6. Does anybody know anything about it's development? Did it die with the SD2, and that's why there's no injected Dolomite Sprints?

The 16v Slant 4 engine is more fun than the 3.5 V8, because you mostly drive it on the upslope of the torque curve.

That car is the Gaydon motor museum, i saw it last weekend. Worth emailing them to ask if they have any info or even if they will let you look round it?

As it happens, I work with the nephew of the engineer who allegedly designed the system. His name was Carl Frederick Lloyd and sadly he passed away in Australia two years ago. After leaving Associated Engineering in the UK he moved to Australia to work for mitsubishi and lived out his retirement there.

Anybody besides me wonder where the throttle body is on that engine?

Also, the grille is Clearly badged Triumph 1500, does that mean they built a smaller version of the Sprint motor?

It is a 2 litre Sprint engine I believe.

If the SD2 had made production the slant four engines would not have been used,
instead they would have been fitted with O series engines.
The TR7 also was destined to be powered by an O series.

There is a bit about this in Graham Robson's book "Triumph Cars".
It gives the costs of each engine and the slant fours were expensive against an O series.
