and 1 screw underneath. CAREFULLY pull the panel backwards until the tab
comes free from the center console. Disconnect the electrical connections and
set the panel aside
Disconnect the end of the throttle cable from the throttle pedal. Using a very
long, skinny screwdriver, press against the underside of the plastic clip for the
cable. Give a sharp blow to the end of the screwdriver to pop the lower end of
the clip free. A lighter pry on the upper side of the clip should release it. Pull the
cable out from up in the engine bay.
2231. Modify alternator cooling duct as shown (this is optional, we
recommend it for a nicer cleaner looking installation). Also another option is
to purchase the European spec radiator support cover which has a very clean
look.
23Modified Cover OPTIONAL

35. Connect the end of the throttle cable to the throttle pedal
2636. Reinstall the interior trim panel – don’t forget to reconnect the
light and buzzer connectors
27Level 2 ONLY…
Mounting of intercooler pump heat exchanger and pump:
37. Mount intercooler pump bracket as shown,
On the 4 doors vehicles, there is a small hole just below the metal inner fender
where the inner plastic wheel housing is attached, this hole is left blank and is
easily visible.
On the 2 door vehicles, a sheet metal bolt that holds the inner fender wheel
house has to be removed and the supplied bolt with nut is used to attach the
pump ( see picture below for a better view of this bolt location)
2838. Mount intercooler pump in bracket with proper orientation as shown
39. Mount intercooler heat exchanger to outboard bumper strut mounts by
removing nuts from studs, mounting supplied bracket to studs and heat
exchanger
2940. Connect hose provided from the pump outlet to the heat exchanger inlet.
41. Locate the after-cooler reservoir / tank and mount it on the base behind
the passenger side shock tower, a 6 mm threaded hole is provided by BMW and
is not used, use the bolt provided and bolt the tank to the base.
3042. Locate ¾” coolant hose that runs from tank to pump. Hose #1
Hoses are marked for your convenience and pre cut to proper length. Route as
shown. Install with hose clamps. Tighten clamp on fill tank.
NOTE: we have cut the hose from the tank to the pump inlet a bit longer for those
of you who have installed euro style headlamps, if you do not have euro style
headlamps you can cut the hose to proper length.
Picture below shows euro style headlamp with suggested hose routing.
31Preparing of engine wiring harness, vanos oil line adjustment,
installing new fuel lines and modification of existing coolant
throttle body water hoses :
43. On OBDI vehicles: Take a pair of dykes and cut the tie straps that hold the
engine harness to the engine bracket that it is attached to, this is needed to free
up the wires for :
A) the throttle position sensor connector
B) the air temperature sensor
C) the idle control valve
Note: on 95 (OBDI vehicles) there is a small 3 wire harness provided to extend
the connector for the throttle position sensor. Use the time now to cut the throttle
position sensor wire and extend it with the wires provided.
It is very important that the above wires have enough length to reach the
sensors otherwise the entire supercharger assembly has to be removed to
correct this!
3244. OBDII vehicles, the bracket that holds all the wiring harness to the
engine block has to be removed and the harness left loose for the sensor wires
to have extended lengths, secure the other wires that are not pertinent for the :
1) Throttle position sensor
2) The air temperature sensor
3) The idle control valve
Take the coolant hose that used to go to the throttle body and route it so that it
goes straight to the cylinder head connection. You have just by-passed the
throttle body heating. There is no provision to heat the throttle body with the twin
screw sc system, but this is not a problem.
See picture below:
Throttle body hoses modified
OBD II only.
33OBDI vehicles, the coolant hose that used to go to the throttle body is now
connected to the hose that used to go to heater in the air box. Cut as
shown below in the picture and connect with the brass 3/8” connector
provided by Active Autowerke.
Take the vanos oil line and loosen the banjo bolt at the oil filter housing, use the
supplied jig and align the hose as shown below. Tighten the banjo bolt securely
after adjusting.
3445. OBDI only: Locate the fuel lines supplied and install them , the longer
line (supply)goes to the front of the engine , route it so that it comes up behind
the oil filter housing, make sure it does not interfere with the steering shaft or
other moving parts, route the other line (return) to the rear of the engine. These
lines will be connected after the fuel injectors and fuel rail are installed
35Installing the main supercharger / intake manifold system:
46. Take the main assembly and slowly lower it on to the engine cylinder
head while aligning the intake manifold studs onto the intake manifold. Support
the manifold while catching the 7 X 11 mm head nuts, run the nuts down but do
not tighten them. Leave them loose so that the intake manifold/supercharger
assembly can move up and down for later alignment of the supercharger snout
bracket to the engine.
47. At this time double check the wires for the air temp sensor, Throttle
position and idle control valve are ok and length is good.
48. Take the snout bracket and slide it over the snout of the supercharger
drive while aligning it to the 2 mounting holes. Insert the bolt with the idler pulley
and spacers, run the bolt down until snug, also install the counter sunk bolt in the
bottom hole of the bracket until flush. Now tighten the intake manifold nuts to
approximately 13 ft-lbs. If you cannot get a torque wrench on them, use your
discretion.
49. Now torque the snout bracket bolts, the upper bolt to approximately 35-
37 ft-lbs, tighten the lower one until the head of the allen key feels like it will start
stripping (it is difficult to properly torque this bolt with such a small head).
Note: some alternators have no threads on the back side so a 10 mm nut
will have to be used to secure the bolt.
Note: We recommend to apply “anti seize “ on these
bolts so that they can be removed for any service
work later on.
36Tighten the pinch bolt on the top side of the snout bracket, it is a 6 mm hex bolt
with a 5 mm head, approximate torque is 8 ft-lbs.
3750. Locate the new supplied fuel injectors and install them now. Install the
wiring harness onto the fuel injectors.
On the OBDI vehicles install the new fuel lines to the fuel rail.
51. Install the supercharger drive pulley on to the shaft and hand tighten the
bolt ( 10 mm allen ).
38For illustrative purposes a line drawing below shows the snout bracket with
applicable fasteners:
52. Install the adjustable idler pulley with bolt and nut provided. The pulley
may have been pre-installed on to the bracket when shipped to you. Snug the
bolt down making sure that the pulley can slide in the slot.
3953. Install the new main drive belt supplied routing it as shown in the
diagram below.
Adjust the “adjustable idler pulley “in the slot for maximum contact around
alternator pulley and tighten the bolt. At the same time it is important to check the
main tensioner for adequate travel,
if the tensioner does not have enough travel it will not absorb or take up enough
slack when loading on the belt occurs. We recommend at least 1” of travel on the
tensioner pulley.
At this time tighten the supercharger belt as much as you can, it is a bit difficult
because it is not easy to hold the supercharger from turning. We recommend
taking a socket wrench and just hold it in place and then hit it with you hand.
Do not be concerned about tightening the bolt, when the engine starts the bolt
will tighten automatically.
Install the A/C belt
40At this time you can install the engine fan clutch along with the fan
Install the new upper radiator hose as well, fill the cooling system and leave open
the bleed screw.
41Level II 1995…
Installing the rest of the after-cooler/intercooler water hoses
from the heat exchanger to the intake manifold:
54. Locate the hose supplied that goes from the heat exchanger to the
intake manifold lower inlet fitting and route it along the frame up into the engine
bay so that the hose has a smooth route, be careful not to kink it. This is hose #3
55. Locate the hose supplied that goes from the intake manifold to the
reservoir and mount it as shown in the line drawing below. This is hose #4
Hose routing and coolant flow
42Picture of # 4 hose installed:
This should complete the hose connections to the after-cooler system.
Level II 1995…
Electrical connections for the aftercooler pump:
56. Locate the supplied wiring harness with relay and route it on the vehicle
as shown in the line drawing.
43Picture of relay mounted level II
Wiring connections at engine main relay level II

57. Connect vacuum hoses as follows:
Vacuum hose layout: OBDI
45Vacuum hose layout: OBDII
58. On OBDII vehicles, relocate the air pump electronic solenoid valve as
shown in the picture below, the valve has to be removed from its mounting
bracket and allowed to sit between the intake manifold and the oil filter housing
46Connecting the inlet pipes and hoses:
59. Locate the vacuum brake booster hose connection on the inlet housing
of the supercharger and also the purge valve hose connection, connect them as
follows :
Note: the factory hose between the purge valve and the intake manifold
must be removed, a new one is supplied
4760. Connect the inlet pipe #2 as shown in the picture:
OBD I vehicles will use the original throttle body bolts to hold the throttle
body to pipe #2
OBD II vehicles will use the supplied studs and nuts
48Connect idle control valve electrical connection and hose to inlet housing
4961. Connect pipe #1 as shown along with HFM adapter hose, HFM and air
filter, reinstall head lamp assembly, connect valve cover breather hose
5062. Locate the original HFM connector and cut the wire off leaving enough
wire at the old plug. Take the new wiring harness that has the new connector
plug and connect the wires. We recommend to solder the wires and shrink wrap
the connections for a positive connection.
OBDI HFM wire harness
OBDII has a similar looking harness with an additional small black box attached
to the harness; see below picture of this box mounted on inner fender of vehicle.
OBDII vehicles
HFM Calibrator mounted
5163. Locate the supplied support bracket for the throttle body:
OBDI :
OBDII:
64. Locate the supplied oil for the supercharger and open one of the 2 fill caps (
6 mm allen key) Pour the oil into the supercharger until all contents are empty
from the bottle. NOTE: the oil is nothing more than synthetic motor oil 15W50 or
20W50, exactly 4.0 ounces is required, no more no less.
Service life of oil is 20,000 miles as recommended by Autorotor.
To replace oil, simply drain from the 6 mm head allen plug at lower side of
supercharger.
52Level II 1995…
Filling and bleeding the after-cooler/intercooler system:
65. Remove all bleed caps from the after-cooler at the intake manifold and the
heat exchanger ( if equipped ), pour in a mixture of BMW coolant/antifreeze and
distilled water in a 50/50 mixture until all the air has escaped from the heat
exchanger, cap off the head exchanger bleed screw, continue to pour in fluid until
all air escapes from the front air bleed on the intake manifold, cap off the front
bleed cap, continue to pour in until all air has escaped from the rear cap, then
cap off the rear .
Note: this procedure may take a while for the air to escape, sometimes up to 20
minutes. Sometimes running the pump for a few seconds can help to push the air
through.
Note: the pump will not run if the DME is not connected. The DME allows the
engine main relay to close which in turn will power up the coolant pump relay.
We recommend that you run the pump for a good 10 minutes to make sure all air
has escaped before locking the cap on the reservoir. You can check this by
looking at the fluid moving inside the reservoir while the pump is running, you
should see a continuous flow of liquid with no air pockets.
53Now is a good time to check for any external leaks in the system.
66. Re-install the front bumper cover and check to make sure that there is not
interference between the heat exchanger and the bumper. Re install the “pork
chops” and all undercarriage parts. Remember to reconnect the fog lamps and
the air temperature sensor.
5467. Locate the intake manifold air temperature sensor that was removed from
the original intake manifold, on :
OBDI: Screw in the air temp sensor into the adapter supplied and tighten very
carefully, be careful and do not over tighten, the adapter is very thin and can
break if you are not careful. Connect the electrical connector to the sensor.
OBDII: IAT adapter and sensor shown:
OBDII : screw in the adapter supplied into the manifold and then tighten, also
be careful, slide in the air temp sensor, it should “click” right into place. Connect
the electrical connector.
55OBD II IAT shown
5668. Locate the bypass valve and slide into place as per the picture shown:
69. By now all hose and vacuum lines should be connected. Reconnect the
DME and double check that oil is in the supercharger, the motor. All brackets and
bolts should be tight.
70. Start engine check for visible leaks, double check the coolant flow inside the
reservoir on level 2 systems.
71. Let engine idle for at least 20 minutes to make sure everything is properly
lubricated. Then test drive.
72. When test driving, make sure that the engine is not knocking under
acceleration, if you hear knock, stop acceleration and gently drive car back to the
workshop. Call Active Autowerke ASAP..
