Superformance GT40 Mk II
GT40P2155
The
Superformance replica of a 1966 Ford GT40 MkII. This particular
model won Lemans, over Ferrari, 1-2-3 in 1966.
Hi-Tech
Automotive
builds the cars in South Africa and they are marketed by Superformance. The specifications...
I ordered
my car in July 2006 (after having driven Dennis Olthoff's car). It arrived in the USA at Olthoff Racing in North Carolina in
December of 2006. The car came
complete except for the engine and transaxle. I took a Pantera
ZF transaxle and had it modified (flipped) to fit the GT40. Gear ratios
are the same (with a
4:22 final drive) except for a .642 5th gear.
Here's the ZF ready to go.
The engine...
It was custom built and dyno'd prior to delivery.
Specs are:
SVO iron block, 9.5" deck height, forged crankshaft 4.0" stroke
Total displacement is 427 cu. in.
Crane custom roller hydraulic cam
SVO 6049B
aluminum heads - ported intake/exhaust, CC'D combustion
chambers, decked
Stainless steel valves, new valve springs,
guide plates, rocker studs, Crane Gold roller
rockers
Ford Motorsports valve covers
It was initially
delivered with a matched SVO M9424-W351 intake and 4 bbl carb.
Dyno results are here. (results
are at an altitude of a mile up near Castle Rock, CO)
Some pictures of
some of the parts prior to assembly....
A picture sent
by Dennis Olthoff prior to arriving and picking it up.
And pictures of
picking it up in North Carolina can be seen here.
How about a couple of movies that Dylan took while I was backing out of
the garage? With a carburetor....
A short version of 25MB and a long version
of 54MB.
After driving it
for a couple of months and fixing some issues... Wiring
mistakes on the front harness, crap in the gas tank which kept plugging
the fuel filter, front sway bar had to be modified, and some other
stuff, I went ahead with the EFI installation that I had planned.
Electromotive TEC3r
ECU, custom individual runner (IR) manifold, TWM throttle bodies, Bosch
injectors, TWM linkage. Since the block was 9.5", an IR manifold wasn't
readily available, so one was made.
Here's a couple
of
initial pictures of my intake manifold (serial #2) sitting on another
engine. (pics courtesy of Kelly Coffield)
In progress
pictures of the EFI are here.
It was quite a job... GT40's are very small cars with not a lot of room
for 'other stuff'!
I then I had to trouble shoot a bad harness...
More pics of the car almost one year later....
The 15" wheels with the Avons are OK, but not what I'd call a great
street tire, so I got the 17" wheels from Vintage Wheels.
I now have them on with Michelin Pilot Sports II.
Fronts are 245/40, rears are 335/35.
I went to Road America in July 2009 to attend the 45th Anniversary of
the GT40. Excellent event!
I went with Jack Houpe and Mike Trusty and we met up with Darryl Adams
with his car.
Some pictures of that event... We unloaded at the hotel and lined up.
The
Superformance area on Saturday. Pretty impressive!
And then we got
to go out on the track in Group 11. All GT40s. Historics and post
historics.
Lots of pictures
available on the Superformance website and elsewhere, so here are some
of me.
Guess who I'm
sitting next to?!!! The car that won Le Mans in 1966. I like this
picture.
Some pictures
out on the track, etc.
And last, but not
least, some of the guys.
Dennis Quella,
Kirby Schrader, Darryl Adams and Mike Trusty
Kirby, Darryl and
Mike on the grid.

Jack Houpe.
A very large video taken
during our visit to Road America. It's 264MB, so be aware.... It
includes shots of the majority of the GT40's on the track as well as
some with Dennis Olthoff racing in Group 5.
