The
Ghost
Nicknamed
the Ghost this is the furthest development to date using the Porsche
Boxster bodywork.
The car has a full ChMo tube frame, mid engine configuaration with
significant development but kept to reasonable equipment for the budget
race team to operate. She is light, powerfull and well balanced and is
a podium car with the right driver everywhere she runs.
This car is fast and beats GT3RS cars and the high HP V8s...one of a
kind...and is a very reliable car with a proven engine and gearbox
combination. The brakes are simply phenomenal and will out last every
other car on the track. The car is set-up for sprints and endurance
racing with good driver cooling, excellent engine cooling, and never
any brake fade.
 This is not a good
first time car as it needs a hot shoe driver to take it to the limits
where it is at home...she is 45%/55% balanced with minimum weight of
1750# but currently adjusted to 2050# with ballast for the local rules.
The chassis is similar to a formula car with a narrow safety cage
around the driver.
The chassis has all the hard points for the engine, transaxle and
suspension in a small size around the driver. This makes for a very
centered and low center of gravity.
 The body is mounted
on lightweight ChMo posts that extend out from the main chassis which
creates large tunnels down each side of the car which are used for
air-management and cooing.
The driver position is on the left side of the chassis to satisfy the
offset driver rule but only enough to pass the regs and no more.
The drivers weight is offset with the computers, driver cooling system,
coolers and oil tank on the oposite side of the chassis.
The car is perfectly balanced and drivers 6' 2" and less will fit well
in the car...the seat is fixed and can use Indy seat foam inserts for
smaller drivers. The pedals are all overhung Tilton with adjustable
position in and out. Brake balance is cockpit adjustable on the fly
with a Tilton balance bar set-up.
The shifter is mounted high and only a few inches from the steering
wheel, the fire system is in easy reach of the driver and is a 3-nozzle
halon system. The steering wheel is an OMP formula suede wheel with an
AIM digital dash display mounted in the wheel. The car is running an
AIM EVO 8-channel Pro-Racing data aquisition system with 8 analog and
infinite digital channels. It can log a 24 hour race if desired.
Currently being data logged: G-force LAT and LOG, Steering wheel
position, Oil temp, oil pressure, RPM, Front tire temp, rear tire temp,
lap times, logger temp, Wide-band O2, thottle position, brake on/off,
gear in use, front wheel speed, rear wheel speed, battery volts. The
entire electrical system is dash mounted with a digital push button
system with circuit breakers (No fuses) and can be reset on the fly.
 Two analog guages
are behind the wheel in case of digital dash failure (Oil temp and
pressure). Drivers view is excellent in all directions and cage is
legal for drivers to 6' 2" tall. No buffeting is felt by the driver at
speed. Engine heat is not felt once underway. Brakes are very light and
have the best feel I have felt in 20 years for racing.
Steering is heavy in the pits but light underway, but not too light
under the bumps. Shifting is cable actuated and light. Clutch is heavy
but only needed to start the car off with the Dog-Box...more on the
gearbox later.
The accelerator petal is long travel and is adjustable it desired to
have a shorter throw, the driver has 5 point cam release belts and xxit
from the car is very fast with the open top and no panels need to be
removed for te driver to get in and out. The Wheel has a quick release
and has the radio push to talk mounted on it.
The gearbox is a special unit that is well supported, It is a
Fortin/Hewland DG300 hybrid using at a 5-speed dog ring box which used
conventional Hewland gears, dogs and sliders but uses an aluminum heavy
duty case that directly mounts to the Porsche engine without adapters.
The Fortin R&P is 9" verses the small Hewland unit. It is using a
special locker which gives upto 100% lock but allows for slip in the
corners. It is mechanical and requires no maintainance.
Shifting the Hewland/Fortin is extremely fast and true. Gear drops are
progresivly tighter as the you go up the gears to 900 RPM in the 4-5
switch, as with all Hewlands you can change out gear sets in 10 mins or
even in a 5 min pit stop if you are organised. The Fortin case is
bullet proof and can take 1000 HP...all Hewland parts are readily
avialable as are the Fortin parts. The box was last built by the
manufacturer 2 races ago...the gearbox has a large cooler and electric
Tilton pump system.
Suspension is inboard hinged long A-Arms front and rear and all points
are rod-end mounted with aerospace hardware everyting is easily
adjustable and there are no soft mounts. Dampers are KONI 2X adjustable
IMSA units. Steering is Rack and Pinion while the Hubs and bearings are
all Porsche. Rear axles are custom made out off 300M material and use
930 CVs. They are overbuilt and have proven reliable in all conditions
(no need to ever change them).
The brakes are 13"/1" 6-piston units in front and 12.9"/.75" 4-piston
in the rear...the balance is perfect...this makes for late braking
passes! The pads can last any sprint season! The engine was custom
developed with CMW Motorsports. Engine is likely the strongest 3.6 ltr
built to date.
The car is for sale for US $49,000
