ECU MODIFICATION REQUIRED
**Please print out the ECU return form (see next page) and include in the package along with your ECU!
This kit requires ECU modification known as “flashing” which is electronic overwriting of the original engine
management software with new software designed for to work in conjunction with your system, and has been
included in the price of your supercharger upgrade. This requires the ECU to be shipped directly to VF-Engineering
for a serial flash of the VF supercharger software. The ECU modification can usually be turned around in 2-3
working days in most cases plus transit time. Any delay does not constitute grounds for product return. ECUs sent
in without the “ECU Return Form” will not be processed.
If you have a performance chip pre-installed you should return it to stock by having the ECU re-flashed at your
BMW dealership prior to sending the ECU. If you do not do this, VF-Engineering flash the ECU to stock for a
charge (1 unit of labor) – there is a risk of locking the ECU when performing this stock “bench” flash because the
ECU is not connected to the car. VF-Engineering is not responsible for losses or costs incurred when ECU’s are
locked.
VF Engineering is not responsible for engine or ECU damage due to an improperly installed or mishandled
ECU
DEALER SERVICE / RETURN TO STOCK
At some point you may take your supercharged car to your dealership for service. The supercharger software does
not interfere with the OBD1/2 engine diagnostics system and remains fully serviceable.
If you wish to return your vehicle back to stock, simply reinstall your OEM EPROM into your DME (for OBD1).
OBD2 ECUs can be returned to stock condition by flashing them at the dealership or using certain aftermarket tools
or contact VF-Engineering who can flash most ECUs to stock.

16. Clamp the original crankcase vent hose back onto the lower connection of the oil separator. The upper
crankcase (S) hose will continue on and connect to a port on the side of the supercharger intake pipe.
17. Install the replacement intake manifold support bracket in the original location.
18. Step 18 removed as kit was updated from V2 (oil fed) supercharger to V3 (self-lubricated unit)
19. Replace your OEM fuel injectors with the direct replacement high flow units supplied in the kit. (See important
notes in RED below). When finished, be sure to refit all electrical connections fully and accurately and reuse
the anchoring points for any plugs or wires.
***NOTE If you are uncertain about this procedure seek professional assistance and do not proceed. Follow BMW
factory workshop guidelines or use official workshop technical manual for instructions on changing fuel injectors.
Always ensure the battery is disconnected, proper air ventilation is provided and you are not working near naked
ignition sources. Fuel vapor can cause nausea, loss of consciousness and lead to injury or death. Fuels and oils
and coolant contain carcinogens (cancer causing agents). Always handle with proper equipment and clean up after.
When working on fuel systems you must follow all health and safety rules and laws set out by the relevant or
equivalent Bureau of Automotive Repair and Government Legislation in your country. VF-Engineering is not
responsible for incorrectly fitted fuel components or consequential losses.

20. Fit ¼” barbed check valve (A) in-line with EVAP (B) solenoid valve vacuum line. Ensure that the white side of
the check valve is facing the direction of the EVAP solenoid. This valve may be located on the d/side frame
rail area on some models. This check valve is a back up valve in case the OEM valve fails. Its purpose is to
prevent manifold pressure travelling the wrong direction in the EVAP system (fuel tank ventilation). You can
blow into the valve to verify which way it operates. You should be able to blow into the white side only which is
why the black side will face the direction of the manifold. Our check valve is supplied with silicon hose to assist
for fitting on other applications. You may need to remove it for your specific application (S52).

25 A small diameter crankcase ventilation hose runs from the top of the valve cover to the underside of the
traction control throttle body. Disconnect it from the throttle body (A) and cap the exposed port on the
throttle body with the cap and clamp provided in the kit. When fitting the supercharger intake duct later
in the instructions, you will need to cut this crankcase hose vent a bit shorter.
26 Take note of the location of the vacuum line running from the same outlet as the crankcase vent on the
valve cover. This vacuum line connects to the underside of the intake manifold. Cut the line half way
between its two connection points and insert the second check valve provided in your kit. Ensure the black
side of the valve is facing the manifold.

31 Hold complete supercharger and bracket assembly and carefully lower into position over the alternator
pulley (A). While lowering the assembly, guide the support brace (B) to the vacated bolting hole in the oil
filter housing and secure together with a few turns of the new M8x120 bolt supplied. (Do not tighten down
any bolts
32 Re-use the original upper alternator bolt (A) with new idler (B) supplied in the kit and mount the
supercharger bracket to the upper alternator hole.
Use either new M10x160 bolt or M10x180 bolt and M10 nut supplied (see note below to choose which to
use), through the supercharger bracket into the lower alternator hole simultaneously fitting the 0.710”
spacer between back of bracket and front face of lower alternator mounting hole.
(**NOTE: There are 2 variations in alternators. If the alternator rear lower mounting hole is threaded
simply use M10x160, otherwise use M10x180 and M10 nut to secure. Both hardware sizes are
provided with all kits.)
V3 service schedule. The Vortech V3 supercharger unit is a self-lubricated supercharger. This means it
has an internal oil reservoir. The purpose of the oil is to lubricate the internal gears. The oil used a blend
created by Vortech and available for purchase from Vortech directly at www.vortechengineering.com
The V3 unit has several brass fittings, one of which is intended for a “breather” (brass fitting supplied in a
clear bag). This fitting is to replace the brass “shipping” plug at the top of the unit. The shipping plug MUST
be removed before the unit is operated (engine turned on) as it is intended to prevent the oil leaking out of
the unit during shipping only. The breather which replaces it, is intended to allow oil vapor and residue to

escape from the unit when it gets hot. The brass fitting next this, is a dipstick and when unscrewed you will
find a “hatched” level stick attached to it. The oil level should be within the hatching.
The supercharger unit has a braided steel oil drain line which is only used to drain the oil out at the
following service intervals. This oil line should zip tied aside free from obstruction at all other times.
Oil change intervals.
Replace oil after first 2500 miles of operation and then every 7500 miles. Oil available from
www.vortechsuperchargers.com
33 Torque the bolts in the following sequence:
Bolt (C) to 32 ft. lbs. (42 Nm).
Bolt (A) to 32 ft. lbs. (42 Nm).
Bolt (D) to 18 ft. lbs. (24 Nm).
Bolt (L) to 15 ft. lbs. (20 Nm)
Bolt (E) to 25 ft. lbs. (33 Nm).
Bolt (F) to 25 ft. lbs. (33 Nm).
Bolt (G) to 25 ft. lbs. (33 Nm).
Bolt (H) to 18 ft. lbs. (24 Nm).
Bolt (K) to 25 ft. lbs. (33 Nm)
Attach end of oil feed line (J) to 90 degree -4 AN fitting on top of supercharger. (***Note: the 90 degree
fitting is screwed into the supercharger brass oil feed nozzle. Do not use Teflon tape or paste sealants as
these may contaminate engine oil and eventually work there way back to the oil feed nozzle which contains
a metal mesh filter screen. If this screen becomes clogged it can restrict oil supply to the supercharger and
cause premature supercharger failure.)

Simultaneously guide the long end of the hose from the bypass valve (B), as well as the complete bypass
assembly under the supercharger and up-toward the open spout on the underside of the intake duct (A)
and clamp. Guide crankcase vent hose (C) onto open spout (D) on intake duct and clamp.
35 Locate vacuum line (A) which runs from under the intake manifold beneath the throttle body to the nipple
on the end of the fuel rail closest to the fire wall. Cut the vacuum line and insert T fitting with vacuum line
from the supercharger bypass valve (B). Ensure vacuum line is securely connected to the valve with no
kinks or risk of chaffing with sharp edges. This vacuum line can be zip-tied aside. Kinks will cause part
throttle issues.

36 Slide the supercharger discharge duct with silicon couplers and all clamps in place (at both ends of duct)
onto the supercharger while simultaneously connecting the hoses from the bypass valve and the Idle Air
Stabilizer to the underside of the duct. You can adjust fitment by trimming the length of the rubber hoses on
the bypass valve in the even that any components interfere with each other. Adjust and secure all couplers
until a complete seal is made. You may need to trim silicon couplers due to manufacturing tolerances.
Ensure you do not over tighten clamps or this will assert too much force on the plastic ducts.
(***NOTE: The appearance of your discharge duct may vary if your vehicle does/does not have traction
control, however the installation process is the same.

37 Connect MAF (A) sensor to the end of the supercharger intake duct. Couplers are purposefully cut to be
short to aid with clearances and help fitment of the air filter. Ensure clamp heads (B) are not resting against
other parts as chaffing will cause damage. The MAF unit is directional so verify that the arrow (C) on the
MAF is pointing upwards, representing the direction air travels through it. Connect the extended wiring
harness to the MAF. Ensure the harness is carefully zip-tied to fixed points and will not be pinched or
chaffed.
(***NOTE: IF THE MAF HARNESS IS DAMAGED IN ANY WAY AND SUBESQUENTLY POWERED UP, THIS
MAY CAUSE A SHORT CIRCUIT AND COULD CAUSE SERIOUS DAMAGE TO THE ENTIRE VEHICLES
ELECTRICAL SYSTEM.)

38 Use the 45 degree silicon elbow fitting to join the air filter to the coupler on the end of the MAF sensor. Your
kit contains a cylindrical airbox for the air filter, but due to variations in BMW production, the air box may
need trimming to allow for variations in fog lights. The airbox can be removed for dry climates, but VFEngineering recommends utilizing the airbox in most conditions. The brake cooler ducts may also need
trimming to allow air to the filter
NOTE: IT IS VITAL THAT THE AIRBOX BE USED IF THERE IS ANY POSSIBILTY OF THE CAR BEING
DRIVEN IN OR NEAR WATER (RAIN OR FLOOD) OR EXCESSIVE DIRT OR SAND.
39 Some bumpers have a grill plate you will need to trim allowing fresh air to enter through the front bumper
into the otherwise sealed compartment where the air filter resides.
(***NOTE: IT IS CRUCIAL THAT THIS DUCT IS OPENED UP AND THE FRONT VENT IN THE FRONT BUMPER
IS REMOVED TO ALLOW AIR TO ENTER. FAILURE TO OPEN UP THESE AIR PATHS WILL RESTRICT
POWER AND THROTTLE RESPONSE GREATLY.

40 See the image below for proper belt routing of the new longer main serpentine belt supplied with the kit.
Use the factory spring tensioner to apply belt tension. Re-fit the OEM AC belt using the factory spring
tensioner.
41 Install the new top radiator hose supplied with the kit (A). Check for at least 3/8” clearance at point (B).
Some variations in hoses (VF supplies OEM hose) may lead to inadequate clearance which can be
resolved by using a slightly large pulley (C). Please contact VF in the unlikely event that this occurs. Re-fill
and bleed the engine coolant. Re-fit main radiator fan.

PREVENTITIVE MEASURES
Change spark plugs to 1 range cooler for extreme driving and hot climates.
Supercharger oil must be replaced at 2500 miles from install and then every 7500 miles. You can purchase the oil
from www.vortechengineering.com
Change engine coolant temp senor whilst installing the supercharger kit (often a cause of fuelling issues on cars of
any age).
When disconnecting OEM electrical connectors, label them to avoid potential confusion when re-assembling.
TROUBLE SHOOTING & MAINTENANCE TIPS AFTER INSTALLING SUPERCHARGER KITS
Injector wiring on older cars can be brittle –check for proper connection
Contact pins inside injector electrical connectors can bend back if the connector is ever mis-fitted and lead to
intermittent connection and cylinder misfire.
Loose crankcase vent tube is considered a vacuum leak and will cause poor fuel trimming.
Loose crankcase vent tube to oil separator is a common cause of vacuum leak.
Vacuum leak at hoses around silicon couplers may not be visible but is a simple mistake.
Weak OEM crankcase vent tube (Melts with age) will cause vacuum leak.
Clean crankcase vent tube and inside of supercharger intake duct every 20K miles and inspect for leaks and kinks
and possibly replace.
SYMPTOMS AND POSSIBLE CAUSES
Hunting idle – major vacuum leak – check silicon couplers especially on throttle body and idle stabilizer.
Smell of fuel – incorrectly fitted fuel injectors.
Misfiring – bad electrical connections to fuel injectors or spark plugs
Overheating – air lock in coolant system
Very erratic idle – verify Mass Air Flow sensor may be fitted oriented in incorrect direction
MAF signal CEL – check wiring harness extension and electrical continuity in extension harness

VF-ENGINEERING SUPERCHARGER KIT OWNERS MANUAL
The following information and recommendations are designed to promote years of trouble free
service for your supercharger. Care recommendations have also been outlined for your vehicle and
maintenance of your supercharger kit.
MAINTENANCE INSTRUCTIONS FOR THE SUPERCHARGER KIT and SUPERCHARGER UNIT
Caring for your kit (mandatory procedures)
1. After fitting, the new supercharger kit should be allowed to bed in for a run-in period of 300 miles during which the engine should not
be driven over 4500 rpm.
2. The supercharger kit should be routinely inspected and maintained as below:
ii.
Air filters – Use the air filter system provided in your VF-Engineering system.
iii.
Air Intake / Air Discharge – Must be in good condition and properly secured. If equipped with flex hose, this must be
Free of damage / leaks.
iv.
Belt Tension – Excessive belt tension can lead to supercharger or crankshaft bearing failure. Do not use a non-slipping
or cog-type belt on a supercharger designed to be driven with a serpentine belt. Replacement belts for your
application, are available from VF-Engineering.
v.
Air Assist – The air assist system on certain Vortech superchargers must be kept free from kinks and leaks. Spare
parts are available from VF-Engineering.
3. Computer Chips – Use the computer chip or serial flash provided by VF-Engineering for this supercharger system. The use of an
aftermarket chip is not recommended as they would not be calibrated for use with a supercharger and can cause detonation. VF
Engineering supplies a computer chip or serial flash with each kit that is specifically developed and calibrated to maximize
performance.
4. Crankcase Ventilation System – You must use the system provided in your VF-Engineering kit to prevent excessive crank case
pressures and possible engine damage. We recommend you clean or replace this every 6000 miles.
5. Pullies – If your supercharger drive belt comes off it may be due to misalignment of the supercharger pulley cause by installation issues
or movement of the mounting plate. Misalignment can also be caused by over-tightening (and failure) of the supercharger belt. For
years of trouble free operation when used for street applications, we recommend the drive ratios not be changed from the standard
specification.
6. In case of recurring miss-firing or detonation / pinging you should contact your vendor. By following these procedures you will ensure
long term durability and reliability from your conversion.
7. The Supercharger oil must be replaced at 2500 miles and then at every 7500 mile intervals. The oil can be purchased from
www.vortechengineering.com
8. Do not use engine oil additives as they may contain solid particulates which can clog the supercharger feed line.
i.
ii.
iii.
iv.
v.
vi.
MAINTENANCE OF YOUR SUPERCHARGED VEHICLE
9. Before supercharging your vehicle we recommend you service and inspect your vehicle. Ideally the fault codes should be reset. This
would highlight any existing conditions that may need attention. The condition of consumables, such as oil, filters, spark plugs, HT
(plug wires) leads, ignition coil, and air mass sensor should be inspected and replaced where needed.
10. Never operate your engine at full throttle when the engine is cold. When starting the engine each day, always allow plenty of time for
the oil to reach full operating temperature before running above 2500 RPM. Full operating temperature is generally achieved only after
the engine water temperature has reached the ‘normal’ indicated operating range for 2-3 minutes.
11. Always utilize the highest octane super (premium) unleaded fuel available in your area. Where possible try to use the same brand of
fuel. Where possible do not use fuels sold at low cost service stations and preferably use national brands whenever possible.
12. After filling up with fuel from a source other than the one you use regularly, carefully listen for engine detonation. If any detonation is
audible, you may have a fuel problem. Cease utilizing heavy-throttle and drive with greater care until the fuel is consumed. If
detonation is still evident, inspect for other causes such as:
Faulty fuel pump(s). Check fuel pressure when detonation is occurring.
Dirty injector(s), clogged fuel filter or pinched fuel line.
Faulty spark plug(s) or spark plug wires with too much resistance. Consult your factory vehicle service manual. Most
wires should not exceed 10 Ohms of resistance.
Faulty ignition coil / distributor. Ask VF-Engineering for diagnostic info specific to your vehicle.
Cooling system not functioning properly. Check for a faulty thermostat, faulty or improper calibration of the thermostatic
fan switch, water pump belt slippage, a plugged radiator or bad fan clutch.
Dirty air filter / cleaner.
13. Ensure the spark plug gap is correct for a supercharged application.
14. We recommend using manufacturer recommended service components or taking the advice from our dealers specializing in the
different makes of cars.
15. Spark Plugs need to be changed at intervals of 8-10,000 miles or sooner.
16. Spark plug leads (wires) must be checked for condition. When reaching the end of their life, they become hard and must be replaced as
a complete set. Check the condition of your coil pack and test for resistance according to OE spec. Check the condition of the
distributor cap (where applicable) and replace if worn or heavily corroded. Replace rotor every 15,000 miles and cap every 50,000 or
as condition warrant.
17. Engine oil should be changed every 3-5,000 miles. We recommend OE oil. Do not mix different grades of oil qualities.
