ENGINE DYNO SERVICE
Engines are properly run on our
engine dynamometer to insure that the camshaft, bearings,
rings, etc. have the correct break in procedure. The engine
is monitored for oil pressure, air/fuel ratio, temperature,
etc. After break in and oil change, the engine is tested for
horsepower and torque.
Flow Bench Testing
We use this valuable tool to measure the flow of your cylinder
heads and set them up for maximum efficiency and performance,
whether for street or track
Our shop features a high horsepower,
state-of-the-art chassis dynamometer with advance instrumentation.
Engines and specialty equipment are tested and evaluated to
dial in the correct carburetor/injector/ignition/manifold
combination for maximum horsepower and performance (street
or strip). We have been developing and testing products for
the auto industry for over 30 years. Through our experience
and our testing program, we can get the maximum performance
mileage from any vehicle.
not just carburetors, points and condensers any more, but
multiport fuel injection, electronic ignitions and computers.
We are experts in finding and correcting hard to detect performance
and driveability problems on any vehicle: foreign or domestic,
street or recreational.
Carburetion and fuel injection systems
are tested under actual running conditions using the chassis
dynamometer. Under load, the fuel system and fuel curve are
analyzed; fuel pressure and volume are checked for each application.
Our Fuel Injection service cleans, matches and calibrates
injectors. We can maximize performance and mileage by achieving
balanced fuel flow.
Our Carburetor service entails recalibrating internal fuel
circuits, rejetting, installing the correct combination of
power valve or metering rods, depending on application, for
optimum fuel flow.
The distributors on early cars can
be rebuilt and upgraded to electronic ignition including complete
disassembly, new bushings installed for alignment and the
end play clearance corrected. On the later model distributors,
new electronics are installed, including a new pick-up coil
and module. The advance curve is then custom calibrated to
Many performance and mileage problems
can usually be traced directly to a weak or inadequate ignition
system. To properly identify these problems, the vehicle is
run on a chassis dynamometer and the ignition output is analyzed.
Then we modify the distributor curve and install a custom
wire set, coil or computer chip for improved performance and
Blueprinting an engine requires
many precision machining operations
Block - Align hone main saddles, parallel boring and honing
with deck plates, equal-distance decking.
Pistons - Checked for size and dome height and then pin fitted;
pistons are notched where necessary for valve clearances.
Crankshaft - Magnafluxed, indexed, machined; oil holes radiused,
journals micropolished. The compression ratio is calculated
for maximum performance.
Balancing - The entire rotary assembly is precision electronically

cylinder heads are magnafluxed; new valve guides are installed;
a multi-angle valve job is done on a Serdi valve machine.
Guides are machined for valve seals. The chamber volume in
both heads is equalized. The head surface is machined and
spring heights and pressures set before the heads are assembled.
All engines are assembled in a "clean"
room and clearanced checked on precision equipment. Camshafts
are degreed to manufacturer's specifications. Camshaft and
crankshaft clearances are set. Optional cam gear drives are
precision set up and clearances set. The oil pump and oil
delivery to bearings is modified for maximum flow. On most
engines, oil galley plugs are converted to pipe plugs. Brass
freeze plugs are used throughout. ARP rod bolts are used in
the assembly. The cylinder heads are torqued to specification;
the intake manifold is fitted for correct alignment to the
heads. The front balancer is installed and exact top dead
center established. The oil pump is driven using a special
pressurized tank to get oil pressure to the complete system
for a trouble-free start up.
AUTOMOTIVE VIDEO LIBRARY
FEAR NOT THE HOLLEY
A new release from the Superior Automotive Video Library,
Rebuilding the Holley Carb, takes the fear out of reconditioning
and modifying the Holley 3310, 4160, and 4150 series four-barrel
carburetors. Accompanied by easy-to-understand narration,
this 30-minute video takes viewers through a typical rebuild
where the smaller details are explained via close-up shots.
Numerous performance modifications are made to the example
Holley 4150, including air-horn removal, milling the carb
body for enhanced metering-block gasket seal, drilling the
primary butterflies for smoother idle with wild cams, installing
a metering-block vent baffle, idle feed-restriction hole enlargement,
beveling the jet orifices, installing secondary jet extensions,
replacing the secondary metering plate with a metering block,
and more. To prove the value of the modifications, the 4150
is bolted onto a big-block Camaro and tested on a Dynojet
chassis dyno where it produces an additional 23 horsepower.
