Frank...
leaving the water valve open for a gain in
capacity and circulation around the rear of the block while adding another
"heat exchanger" into the equation is not a trick.
Between Anton/Vizard is 60 years of experience in road, track and rallying the
Series A. These fellows should know at least something about it? :)
The foregoing (according to them) will result in overall (and "locally") cooler
operating temps in your day to day
daily driver excursions. It's an "operational"
recommendation, NOT a cure for mechanical ills.
If the rad/water-pump or whatever
is truly clapped out, then it's
clapped out and no "tricks" will fix it and
I'm guessing this is what you meant by
"tricks"?
All other things being equal....
for the road, the "45" will "outrespond"
it's counterpart SU (same flow capacity) set-up any day of the week, as the
former is
open/fixed venturi while the latter "variable
venturi" type's air valve initially "gets in the way" as it "struggles" to open
in response to whatever vacuum the engine
is capable of generating. No discussion
warranted here for sure. Strictly mechanical differences.
However, once the revs come up, it looks
pretty equal. How do we know this???
By experience and not only on the flow
bench.
For when the SU is specifically set up
for the track, under circumstances wherein the air valve is dis-abled, the
SIMILIAR flowing SU set-up becomes "open choke" and is now a "match" for the
SIMILIAR flowing Weber set-up.
Of course, such an SU loses calibration for
the road whereas the Weber has no such
concerns! :)
Yeah...I loved the "45" on my PO'd tuned
"Vizardized" 1380, despite the fact I used
to have to remove it for a thorough internal cleaning from time to time. K&N
filter and sealing grease aside, the tiniest
grit would foul the Weber's tiny channels
over time. I mean this became part of
Spring Cleaning, really. :)
But even replacing the stock SU set-up
with a "45" calibrated for the application
made a helluva difference when I initially
got into "45"'s running a stock 1275. Night
and day really.
Of course, the last is not intended as a comparison between SU/Weber at all,
considering the obvious superior flow
capacity/rates of the latter set-up
over the former stock set-up. But this is
what you paid the premium bucks for, eh? :)
