T&V RACING’S OVERKILL CRANKS AND
CRANKCASES
The ultimate nitro burning Harley bottom-end.
These are the cranks and crankcases that
have put Nitro Harley racing into the new
Millenium. When you demand the highest possible
from your nitro burning race engine, the
only way to go is “side-by-side”.
The cases are CNC machined from heat treated
aircraft quality aluminum with a huge roller
bearing on the pinion side and a huge ball and
roller bearing on the output shaft side for
extreme load handling and stability. The camchest
is of a Sportster type configuration for
better pushrod geometry and is premachined
to accept an external cam driven
fuel pump and oil pump. The one piece crank
is made out of a special heat treated chromemoly
alloy and uses a special pinion shaft,
which has the pinion gear directly machined
on it. This is to ensure it can handle the
stress of excessive exhaust pressure combined
with driving the fuel and oil pump.
The last weak-spot of the side-by-side configuration
is the bolt and pin pattern on the output
side of the cranks. Zodiac racing has the
cure and exclusively offers a new generation
side-by-side crank that has a splined output
shaft. Also made from a super tough heat
treated chrome moly alloy and machined to
exact tolerances, these cranks can handle
more load then anything else on the market
today.
T&V Racing’s Overkill bottom-end configurations
can be ordered for engines up to a massive
200 Cubic Inches.

T&V RACING 7075-T6 BILLET CONNECTION
RODS
T&V Racing connecting rods are CNC
machined from a special aluminum alloy plate
that provides a combination of high strength,
high fracture toughness and good resistance
to fatigue crack propagation at high stress
levels. Our manufacturing process takes
advantage of the CNC's capability in that the
rod is custom built around the actual center
to center distance. These rods are then
honed to size, holding a precise tolerance.
These rods are designed for the so called
“side-by-side” race engines, like T&V Racing’s
Overkill engines.
Our latest version for Nitro Harley Top Fuel
Rod features:
8”, 8.5” and 9” rod length
Extra wide small-end width for better load
distribution on the wrist pin
7/16 ARP bolts
1.094” wrist pin housing
2.500” housing bore

BDK FUEL METERING VALVE
The BDK metering valve is used on front running
nitro burners to accurately control the
amount of high flow fuel volume bypass. The
base pressure is simply adjusted by setting
the spring pressure with the T-handle. But
unlike normal bypass valves, the BDK metering
valve gives you the opportunity to regulate
different pressures at different phases of
the run. This is the fuel valve that can maximize
traction at the start-line, maximize
acceleration half way down the track by
boosting up the fuel pressure, and maximize
top end speed by leaning the engine out at
the high RPM range. This is regulated by
pressurizing and depressurizing the air chamber
of the valve.
It accommodates two AN-8 fittings for the
fuel inlet and output and a Festo/SMC type
quick release hose fitting for the air pressure
chamber. This valve is used by all the Pro’s in
Nitro racing.
