I have not had the 7 above 150Km/H, not really much point. Not too
good an idea in Oz now the boys in blue have forward facing radar in
their cars.
My Morgan +4, [no windscreen, small aero screen] in 63, when it had
only 79BHP, at 4600RPM at the wheels, [probably somewhat more at
5500RPM, but probably not to much more at 6300] was timed at
124.4MPH down conrod straight.
In 64, with 115 BHP at the wheels, same revs etc, was timed at 124.6
MPH, at the same place. So 36 BHP will give you 0.2 MPH, by that
reckonimg.
The best I got, with windscreen on was 115 MPH.
The 2.5L Brabham [claimed about 310 BHP] was timed at 174.6MPH same
place, in 68. A Ferrari P4, & a Lotus 19B, with 2.7L climax did 181MPH.
8 years earlier, 2.5L Cooper Climax [with no more than 210 BHP, were
timed at 186MPH, & may have been higher in other years.
The Coopers had 6 inch wide wheels, but by 68 the rear wheels were
up to 16 inches wide. The extra drag killed the speed in all the F1s
with those wheels.
My Brabham 1100cc Cosworth, with 108 BHP flywheel at 7600RPM, [may
have been a bit more at 8300RPM], & 6" front, 7" rear wheels did
145MPH same place, in 1967.
In a butchers picnic race, [20 fastest cars] at Lakeside, the P4
Ferrari, & a Traco Oldsmobile sports car, both had 15 MPH on the
Brabham, up the straight, but I could keep up, on half throttle,
with a tow from the Ferrari.
Why things get their speed is very interesting, & sometimes doesn't
make much sense.

PS, Hay, Odd, how fast can you tow that van. With a late 50s V8
Chrysler, I used to tow my Brabham, in an enclosed trailer at 80, to
90MPH regularly, back when that was legal.
I once got it up to just over the 100MPH, on the long downhill
straights in Victoria, but I had to slipstream a semi trailer
pantechnicon to do it. Young & silly, you know.
