I was looking over some Triumph material and this question came to mind. Why
is it that the fuel injected TR6 had so much more power than the carb
models? I know that fuel injection allows more precise metering of fuel and
all that, but 50hp worth.
The main reasons for the 46HP gain are that the PI car had:
1. a wild camshaft (valve timing 35/65/65/35 compared to 10/50/50/10 on the
carb'd cars)
2. increased compression ratio of 9.5:1 compared to 8.6:1 on carb'd cars
This question is further confused by the fact that my father's Morgan Plus 8
recently threw off it's fuel injection and went to carburetors. This change
will fix it's driveability problem, but will also result in an additional 20
or so horsepower gain.
I have no idea of the effects of PI on the Rover V8, I'd like to know
though, someone on the list must know why?
But some people belive that the Morgan's drivability problems have more to
do with them having the ergonomics of a pre-WW2 car ;-) (not me though)
Just curious
As am I, its the only way to learn ;-)
