Dynamometer Services
Pro-Auto Performance Center, Inc. is proud to offer high performance
Dyno testing. We can dyno test most engines and provide you with
a computer print out of the results.
Dynamometers, or "dynos," are devices used to measure
mechanical force, also referred to as horsepower. These instruments
are used to determine the power of automotive motors, boat motors,
truck pull motors, and many more.
Most commonly, dynos are used by racing enthusiasts to determine
the horsepower and efficiency of their car's engine. This can
allow them to pinpoint issues with their vehicles in seconds,
whereas going strictly by track tests can cause major delays
and misdiagnoses, wasting precious time and effort! In a sport
where fractions of seconds count, a dyno can give racers an extra
edge in competition.
What Does A Dyno Test Tell Me?
The data acquisition computer corrects for acceleration and
deceleration inertia, reads torque, rpm, 12 exhaust gas temperatures,
fuel flow, air flow, inlet air temperature, engine oil pressure,
engine oil temperature, engine manifold pressure, and engine
water temperature channels over 1,000 times a second. Barometric
pressure and humidity inputs along with the inlet air temperature
channel are used for correcting horsepower and torque to a known
standard (SAE J1349, J1228, J607, J245). Also recorded are calculated
channels such as volumetric efficiency, brake specific fuel consumption,
brake mean effective pressure, air fuel ratio, EGT average, and
EGT delta.

Shop Service
What the heck is a machine shop? We have all heard of them,
but there doesn't seem to be a bunch of machines coming out of
a machine shop, so what actually goes on there?
Essentially a machine shop is a place where material (usually
metal) is machined. Still not good enough? How about if we say
that machining is the term used to describe the removal of material
from raw stock, to turn it into a usable part by turning, milling,
drilling and Grinding.
Turning
Turning produces cylindrical parts. The concept is the same
as a wood turning lathe where a cutting tool is applied to raw
material that is spinning rapidly. The cutting tool makes the
stock circular (changes a square or rectangular piece of stock
into a round one), and can reduce the diameter of the circular
stock to match a predetermined pattern.
Milling
Milling is the process of cutting away material form the raw
stock to match a predetermined pattern. In milling, a work piece
is fed past a series of multiple toothed cutters. The cutting
action of the teeth on the milling cutter removes excess raw
material. The finished product can be curved, flat or even angular
in any combination of shapes
 Drilling
Drilling is something that we are all pretty familiar with.
It means boring a hole into raw stock. The cutting tool that
is used to bore the hole is called a drill.
Grinding
Grinding is the wearing away of material by the application
of friction. Machine shops likely use high powered mechanical
grinders, but we have all done it in a small way, when using
a piece of sandpaper on a rough piece of wood.
 We
can design intricate metal parts, and manufacture them to within
tolerances of thousandths of an inch.
