The Mini's FI is factory, single point injection. I think FI's benefit is
generally going to be better driveability across the rev range. For out and
out top end I imagine a carb that's set up for high RPM would beat it. On
the down side on this car is that a previous owner has fit a big-bore
exhaust that I think probably hurts low-end torque, which is what I want on
a street car. It truly gets up and goes at 4000+ RPM, but it also rather
buzzy at 3500-4500 RPM. That's an unfortunate spot for the resonance to be
nasty since I tend to keep it there. It does fire up on the first stab of
the starter button and gets 30-35 MPG. The fact that it's something I don't
think about is a benefit; it's a non-issue. It runs.
It's kind of hard to compare performance to a carb, since there are so many
variables. The car itself is heavier than my '61 Midget was with a dual-SU
1275. This car also has the "stage1" kit (bigger throttle body, big-valve
head, header and sump guard.)Plus, the closed-car driving experience is
different enough that a lot of my impression is going to be subjective. The
Midget is off the road right now so side-by-side test is impossible.
To be honest, I'd have to live with it for a little while before I had a
considered opinion. Of course FI is obviously "the modern thing to do."

Phil,
You said the Mini had fuel injection, is it new enough that it had the
f.i. from the factory, or was it fitted by someone? How do you think
it compares to a carb engine?
Thanks
