Air/Fuel gauges
LM-1: Digital Air/Fuel Ratio Meter:
Tuning an engine for maximum power
previously required long trial-and-error sessions on a dynamometer. With
the
LM-1, precise AFR measurement allows the user to correctly adjust
many variables- including carburetor jetting, fuel
injection, turbo fuel curves, etc.- without long and expensive dyno
sessions. The meter’s digital signal processing
technology provides data on exactly how rich or lean an engine is
running at any load. The LM-1’s self-calibrating
circuitry also compensates for changes in temperature, altitude,
and sensor condition.
The instrument can sample and store the air-fuel-ratio and the
other sensor data internally in operation for later
analysis on a personal computer. At a sampling rate of 12
samples/second the instrument can store up to 44 minutes
worth of data in non-volatile memory. The data can be downloaded to
a personal computer using a standard serial
port and viewed/analyzed by the included software or any standard
spreadsheet program.
The standard LM-1 includes a
Bosch wide-band oxygen sensor and cable, cigarette-lighter adapter/power
cable, serial
cable for PC connection, exhaust bung and plug, CD and manual. The LM-1
ships with a Bosch sensor, however, it can
also function with other wide-band sensors, including Honda/NTK and VW
sensors.
Camshafts
We use Engle and Webcam
camshafts in conjuntion with Scat laser drilled lifters. Steel straight
cut or aluminum cam
drive gears are available.
Carburetors
The new Empi 40mm and 44mm HPMX
carburetors have just been released as a replacement for the Weber IDF
series. The airflow and horsepower capabilities have been improved
over the Weber with all jets being
interchangeable. The 44HPMX's come with 36mm venturis while the
40HPMX's are 28mm in size.
Previously called a "Kadron" carburetor, this
40mm Solex design is now being manufactured by Empi. The single
throat design provides plenty of power in a dual carb
configuration, and is easier to tune and to work around than
the 2 barrel carb sets. These are also being made available in 46mm
and 48mm sizes, and have powered a full-
bodied Volkswagen to mid 11 second ET's. A lighter weight dedicated
race car is currently being readied to go even
faster while being fueled with methanol.
This is a set of new Weber 48ida
carburetors. They are available in the stock cast finish or they can be
fully polished.
This set has also been bored out to a 51.5mm throttle plate size.
Cases
Engine cases are
available in a genuine VW magnesium alloy or the new Auto Linea case cast
in aluminum.
Machining is available for larger bore cylinders, stroker crank
clearancing and oil system modifications. Chromoly
head studs are also available in different lengths and different
alloys
Clutches
Clutch discs are
available in woven metallic, feramic puck style, or sintered iron
"slipper" discs.The "Black Iron" disc
allows a lighter pressure plate to be used, which cushions the
shock to the transmission, but with the "grip" of the
clutch increasing as it gets hot.
Connecting rods
We use several different
styles of connecting rods. Resized genuine VW rod are most often used with
stock stroke
applications, and can also be clearanced for small stroker cranks.
Forged chromoly I-beam styles are strong and
inexpensive, while the forged H-beam design is pretty much the
strongest and lightest that we sell. For special
applications The Cunningham company provides us with custom rods to
our specifications.
Cooling systems
We weld ALL of the attachment points on a
new fan where the blades are crimped into the fan ring. This eliminates
the dreaded "exploding fan" syndrome where the fan comes apart and
tears holes into the fan housing and oil cooler.
Crankshafts
We have counterweighted crankshafts from
69mm to 90mm strokes, using either factory VW forgings, or 4340
chromoly from Bugpack or Scat. Our flywheels are all 8- dowel
pinned with wedgemating or flanged attachment
available. Rod journals come in either VW size or 2.0" Chevy
diameter.

Ignition
The MSD brand distributor uses a
magnetic pickup instead of points to trigger the spark, The advance curve
is fully
adjustable and the shaft rides on ball bearings. The plug
connectors are also spaced further apart to avoid any
crossfire that can occur with a high energy spark.
Nitrous oxide
Nitrous oxide injection
is another way to add power to your engine. You can add from 25hp to
upwards of 150hp
with a simple jet change. The fuel system has to be modified, and
with a big "shot" of nitrous other modifications
are necessary. If a complete "kit" from either Nitrous Express or
NOS is used, reliability can be as good as any
other method of increasing horsepower.
Pistons & cylinders
This Wiseco piston is made from a forged
aluminum alloy and utilizes a "slipper skirt" design. This piston is
lighter
and much stronger than a Cima brand.
Pulleys
Conventional size and "power pulley"
sizes are available made by Scat, Empi or Gene Berg. They are sold in
polished or black anodized finishes in aluminum, all steel, or a
steel hub with an aluminum outer.
This serpentine pulley kit uses
a modern grooved fan belt. With one piece billet top and bottom pulleys
and an idler
pulley providing tension, the chances of losing a belt and burning
up an engine are greatly reduced.
The Fisher harmonic dampner is designed to control the twisting of
the crankshaft under a load. This smoothes out
the running and prolongs the life of the crank.

Sumps
Torque bar
The Proformance Racing torque bar supports
the frame horns to prevent flexing. The leading cause of “wheel hop”
is from the horns bending up under a load, and then springing down
when the tire looses traction. The tires then grab
and the processes repeats itself. The torque bar is chromoly steel
and bolts between the shock towers. The down bars
are aluminum with left and right hand threaded “heim” joints. The
mounting tabs are laser cut steel and need to be
welded to either the rear mount or directly to the frame horns. The
down bars are also machined with a hex shape so
a wrench can be used for adjusting the preload.
Transmissions
Transmissions are
available for all year VW's; swing axle, IRS, or bus. Available are
standard rebuilds, heavy duty
“ProStreet” style boxes and all out racing applications.
Turbo kits
Coming soon.
Other products
This is a billet aluminum full flow oil pump
cover plate. When the oil pump outlet is internally plugged all of the oil
flows out of the cover, through your filter, then back into the
motor, filtering 100% of the oil.
These are the new M&H DOT approved street
legal "slick". They are available in either the 6 inch width, 26inch tall,
or the 8.5 inch by 28inch tall.
Proformance has just re-introduced
their billet tach mounts. These mounts are CNC machined from aluminum and
will hold your Autometer tach on your VW dash. It requires drilling
only one 3/8" hole for mounting. Price is $64.95
fully polished or $59.95 in satin. |
