RACE SUPERCHARGER SYSTEM

OWNER’S MANUAL

ENGINEERING, INC.

SECTION 1

ENGINE STARTUP AND FUEL CONSIDERATIONS

1. Never operate your engine at full throttle when the

engine is cold. When starting the engine each day,

always allow time for the oil to reach full operating

temperature before running above 2,500 RPM. Full

supercharger operating temperature is generally

achieved only after the engine water temperature has

been at the normal indicated operating range for two

or three minutes.

2. Always use the highest octane fuel available.

3. Always listen for audible detonation.

SECTION 2

GENERAL SUPERCHARGER SUPPORT

SYSTEM RECOMMENDATIONS

1. Air Filters - Always use an air filter on the supercharger

inlet to prevent the supercharger from ingesting foreign

objects.

2. Air Intake/Air Discharge - Must be in good condition

and properly secured. If equipped with a flex hose,

this must be free of damage/leaks.

3. Belt Tension - Excessive belt tension can lead to super-

charger or crankshaft bearing failure. Do not use a

non-slipping or cog-type belt on a supercharger de-

signed to be driven with a serpentine drive belt (non

heavy duty). Replacement belts for your application

are available from Vortech.

4. Crankcase Ventilation System - You must use the free

flowing, baffled system provided to prevent excessive

crankcase pressures and possible engine damage.

5. Pulleys - If the supercharger drive belt comes off dur-

ing operation, it is most likely due to misalignment of

the supercharger pulleys caused by installation pro-

blems or movement of the mounting plate. Misalign-

ment can also be caused by overtightening (and fai-

ling) of the belt, which can negatively affect the

supercharger and crankshaft bearings.

SECTION 3

NORMAL MAINTENANCE RECOMMENDATIONS

1. Clean the supercharger oil inlet fitting at every oil

change. When the vehicle is cold, remove the oil

inlet fitting at the supercharger and clean it thoroughly

utilizing high pressure air to blow the orifice clean

before reinstallation. Do not attempt to remove the

screen/filter inside of the oil feed fitting. This oil inlet

fitting is designed with a very small orifice, which

provides a mist of oil directly onto the gears. Never

use Teflon tape or other sealants on any oil feed line

fittings. Do not overtighten fittings.

2. Use manufacturer's/engine builder's engine oil and

oil filter recommendations. Do not use engine oil

additives as they may contain solid particulates such

as moly or Teflon which can clog the supercharger

feed line.

3. Spark Plug/Ignition System Guidelines - Vortech re-

commends the use of spark plugs that are at least

one to two heat ranges cooler than what is stock

utilizing a plug gap of .030" - .040". The use of

premium high performance "spiral core" ignition wires

are required for optimum performance as well as

dielectric grease on the inside of the wire boots.

Ignition amplifiers such as Crane HI-6/7 or MSD

6/7AL are also required for boost levels over 10 psi.

SECTION 5

SUPERCHARGER CARE GENERAL

RECOMMENDATIONS

1. Check and select your impeller speed per guidelines

outlined in Section 7 of this manual.

2. Select the correct compressor performance for the job.

Vortech offers compressor matching services to help

you select the proper supercharger for your application.

Contact the Vortech Sales Department for details.

3. Use the proper compressor bypass valve on all high

rpm or racing systems.

SECTION 6

CUSTOM SUPERCHARGER MOUNTING

INFORMATION

1. The supercharger must be mounted within 50° of

vertical. That is 50° to the left or right with the lowest

of the three oil return provisions selected for the

drain. This is to provide proper return oil drainback

The compressor housing may be loosened and rotated virtually 360° for optimum outlet alignment. The supercharger mounting holes are 3/8-16 x 7/8" deep. The tensioner plate holes are metric: M12-1.75 x 3/4" deep. It is imperative that the tensioner plate pivot bolt in the center of the gearcase cover not be allowed to bottom out.

more overall horsepower and slower supercharger speeds to attain a significant horsepower increase. 5. BELTS AND PULLEYS a. Serpentine Drive Belts-The faster you spin a supercharger, the greater the tendency for belt slippage to occur. Most vehicles respond differently as to when the slippage will occur. 6 rib systems are more prone to slipping because they have less surface area for the belt to grip. An inherent design characteristic of serpentine belts is a certain amount of belt slippage.

The above mentioned parts are strictly Ford specific. APPROVED MOUNTING PLATE SUPPORT METHODS ARE AS FOLLOWS: • An adjustable strut rod between the crankshaft and the supercharger pulley. • A static strut rod between the supercharger mounting plate and the engine (header, flange, etc.). 2. DRIVE BELTS - Vortech recommends the use of the widest cog belt that is practical and one that is Kevlar reinforced, to be used to help prevent belt breakage. The belt must not be overtightened.

too much horsepower for your suspension), you may experience a supercharger failure. Traction loss can cause the engine and supercharger to be rapidly accelerated and decelerated as well as overspun, resulting in a premature failure of one or both. Listed below are some precautions that must be observed: • The engine rpm should not and does not need to exceed 4500 rpm in the burnout box (use rev limiter). • The burnout should only be done in one gear. Do not start in first gear and shift into second.

Compression Ratio: The ratio of maximum engine cylinder volume (when the piston is at the bottom of its stroke) to minimum engine cylinder volume (with the piston at TDC). Thus, the theoretical amount that the air to fuel mixture is compressed in the cylinder. based on an air-fuel value known as stoichiometric or 14.7:1. In most fuel injection systems rich/lean is determined by voltage signal from the oxygen sensor. An excess of oxygen lean is a voltage of less than .4 volts.
PAGE 7
Pressure Ratio: Manifold absolute pressure divided by standard barometric pressure. Pressure Ratio = gauge pressure + atmospheric pressure divided by the absolute pressure. The vertical scale on a compressor map and it indicates the pressure rise across the compressor. It is scaled this way instead of psi because the inlet conditions are unknown. Pressure Regulator: A spring loaded relief valve that returns excess fuel to the tank to maintain system pressure.
