When I lived in England (1997-2000) I stumbled onto a primrose yellow
e-type “street” car that had a very interesting engine. The motor had been
built by Judd (F1)at a cost of over 30,000 GDP. Everything but the iron
block was new design. According to the Essex shop curator who maintained
the car this was the most powerful xk motor “ever”. I have no other info on
this engine. This is very little to go on, but does anyone in UK know any

Subject: [racing] Most Powerful XK Inline 6 Cylinder Engine

Greetings fellow listers! Perhaps I may have missed the thread or not
researched the archives that well but, is there any records of the most
powerful Jaguar XK inline 6 cylinder engine? When I mean “most powerful”,
I’m speaking about all aspects as in torque, horsepower, RPM redline, etc.
I guess fuel efficiency would be irrelevant. I would like to find out how
that engine was set up as in: total displacement, type of block (iron or
aluminum), type of pistons, type of connecting rods, valve diameter, head
angle, cam timing and grind, carburetor or injection, dry or wet sump,
inlet and exhaust diameter, type and diameter of exhaust headers, type and
diameter of intake runners. I know that the behavior of the engine can be
tuned by experimenting with various lengths and diameters of manifolds or
runners. I also realize that the aspects of what you want the engine to do
will depend on what you intend to use it for, such as short distance
sprints, long distance endurance runs, !
hill climb rallies, etc. Hence, I’d also like to find out what vehicle or
chassis type it was used in, what gearbox was mated to the engine and what
type of race was it used in. Most importantly, who gets the credit for
designing such a monster and if they would produce or still are producing
more clones of that engine. Sorry for the lengthy series of questions.
Maybe I might find the answers myself and if I do, I’ll post my findings.
Thank you for reading my inquiry.

Very Respectfully,
