Firing Order – 1, 2, 4, 3. Cylinder 1 is on the left hand side of the engine (Generator side).

Installation

The engine should be mounted into the chassis by means of four bolts into the mounting points on each side of the cylinder head and two bars through the horizontal rear mountings in the crankcases above and below the gearbox through the rear engine Brace. See next Page for Rear Engine Brace fitting procedure. Ensure no looms or hoses are trapped between the engine and chassis. All sensors should be connected correctly and in working order, including:

• Air charge temperature • Crank Position Sensor

• Oil pressure • Fuel Pressure (if applicable)

• Coolant temperature • Throttle Position Sensor

• Oil temperature • Barometric sensor

• Cam Phase Sensor (if applicable)

The oil system must be connected as per the information in this operation manual. Please read this document carefully, there are different types of oil system fitted to RPE 4 cylinder engines. Please ensure the correct oil system is used. There is more information on the various oil systems on pages 2 to 7.

PLEASE BE AWARE THAT FITMENT OF AN INCORRECT OIL SYSTEM COULD CAUSE AN ENGINE FAILURE AND WILL INVALIDATE YOUR ENGINE WARRANTY. The coolant system must be connected and capable of providing adequate cooling to maintain the correct operating temperatures outlined later in this document. Please contact RPE if you have any questions concerning the installation of your engine. Contact details are listed on page 16.

REAR ENGINE BRACE

Dear Radical owner, mechanic or distributor,

Your engine has been returned with a supporting brace on the rear of the engine:

In order to fit your engine you will need to modify the rear engine cradle by removing a boss as shown:

1

Oil System

Recommended – Silkolene PRO R or PRO 4 15W-50

PRO R/4 is a unique, fully synthetic lubricant for ultimate engine protection and superior clutch and gearbox operation for high performance 4 stroke motorcycle engines.

If this specific oil is not available to you, please use a comparable oil.

NEVER USE CAR ENGINE OIL IN A MOTORCYCLE ENGINE. THE INTEGRAL GEARBOX WITHIN THE MOTORCYCLE ENGINE WILL SHEAR THE MOLECULES IN THE OIL. ALSO, MOTORCYCLE ENGINES HAVE INTEGRAL WET CLUTCHES.

Coolant System

50% water and 50% antifreeze/summer coolant.

Fuel

RPE Suzuki engines should be run on a minimum of Super Unleaded 98 RON, or 100 octane race fuel. Tuned engines in the USA should be run on racing fuel such as Cam2 or a minimum of 108 Octane.

Octane Boosters

If fuel of the correct octane level is not available then octane boosters can be used, please contact RPE before using octane boosters in fuel.

RPE – Quaife Gear Drive System

Recommended Oil – Shell Helix Racing Gear Oil 75W-90 Shell Helix Racing Gear Oil 75W-90 is a synthetic gear oil designed to provide optimum protection under extreme load conditions, whilst maintaining high efficiency.

Oil Systems Variations

Due to a number of different oil cooling systems in circulation, the oiling system must be confirmed before the engine is installed.

Oil System Number 1: 2 blanking plates installed on the engine oil cooler inlet and outlet ports and the oil jet behind the oil filter is removed. Oil System Number 2: -8 or -10 oil cooler fittings on the engine oil cooler inlet and outlet ports, and the oil jet behind the oil filter has a 3mm hole drilled in it. Oil System Number 3: -8 or -10 oil cooler fittings on the engine oil cooler inlet and outlet port. A blanking bung is installed behind the oil filter, in place of the oil jet.

• On later model engines, that are fitted with a cast type sump pan, there is only one type of oil system regardless of installation. One blanking plate on the oil cooler inlet port and the oil jet behind the oil filter is removed.

• If you are unsure as to the specification of your previous engine, RPE can provide you with the necessary information.

• An RPE technician can also confirm the specification for you if an engine exchange is to take place at a race meeting.

• If in any doubt please Phone or Email

Oil Type Number 1 - Blanking Plates, No Jet

This type of oil system can be used with both RPE cast (Silver) and billet (Gold) dry sump pans. The restrictor jet behind the oil filter is also removed. The oil return pipe from the scavenge pump goes through the oil cooler (or water to oil heat exchanger) before returning to the oil tank. Cast Sump

Jet Location

If the engine is fitted with a cast sump pan, there will be no blanking plate on the sump pan, just one on the engine.

Billet Sump

Jet Location

Blanking plates are fitted to the engine’s OEM oil cooler in and outlet ports.

IMPORTANT

When this oiling system is used, the jet behind the filter must be removed.

IF THIS IS NOT DONE IT WILL RESULT IN ENGINE FAILURE.

3

Oil System Number 2 - Oil cooler fittings and jet

This system can only be used with RPE billet dry sump pans.

Jet with 3mm diameter hole

There are two fittings on the engine oil cooler inlet and outlet ports, they are either -8 or -10. In this case there is a restrictor jet with a 3mm hole located behind the oil filter. The oil returning from the scavenge pump is pumped directly back to the oil tank.

IMPORTANT

When using this oiling system, the jet behind the filter must have a hole drilled in it.

IF THIS IS NOT DONE IT CAN RESULT IN ENGINE FAILURE.

Oil System 3 – Oil Cooler Fittings and Bung

This system is mainly used on the Radical SR4, as they have long hoses that run to and from the oil cooler due to the radiator being mounted further away from the engine than normal

Blanking Bung

There are two fittings on the engine oil cooler inlet and outlet ports, they are either -8 or -10. In this case there is a blanking bung behind the oil filter. The oil returning from the scavenge pump is pumped directly back to the oil tank.

IMPORTANT

When using this oiling system, the jet behind the filter has no hole drilled, it is a solid bung.

IF THIS IS NOT DONE IT CAN RESULT IN ENGINE FAILURE.

Throttle and Airbox installation

Airbox

Ensure that all fixings on the air box are tight and there are no foreign bodies that could fall into the engine and cause damage once the engine has been started. All bolts/screws in the airbox must be lock wired or fixed using thread lock.

Fluid Levels and Temperatures

Coolant Temperature

When the engine is on track, the coolant temperature should be between 70°C and 90°C.

Coolant Level

When the system is fully bled, the coolant should be full to the top of the swirl pot, and there should be a minimum of 10 to 20mm in the coolant catch pot.

Oil Temperature – both Wet and Dry Sump Systems

When the engine is on track, the oil temperature should be between 90°C and 115°C.

Wet Sump Oil Level

The procedure for checking the oil level is as follows. This should be done with the car on level ground. With the engine running and the coolant up to 50°C, hold the revs at 3000 rpm. There should be no bubbles in the sight glass, from 3000RPM, blip the throttle and an air bubble should appear in the sight glass.

The sump is baffled and the oil takes some time to settle.

Dry Sump Oil Level

For cars fitted with a dry sump system the oil level must be checked using the dip stick supplied. The dry sump oil tank level must be maintained at the TOP mark on the dipstick with the engine as close as possible to the recommended on track running temperatures (See Fluid Levels and Temperatures opposite). The bottom mark is only used when the oil is cold. The level should be checked AFTER running the engine up to temperature and after holding the revs at 4,000rpm for ten seconds, to allow the oil to be scavenged back to the oil tank. The engine should be turned off to check the level. (The sight glass in the side of the engine should be ignored).

If you do not have the correct dipstick for checking your dry sump tank, contact a member of the Radical Parts Department immediately. Their contact details are on page 16.

a. Always start the engine with a laptop connected to the ECU so that all engine parameters can be monitored during warm-up. This also confirms all the vital engine sensors are working. b. Check plenty of oil is visible in the oil tank and the coolant level is to the top of the swirl pot.

c. The engine should be dry cranked, some oil will have drained back into the engine if it has been previously run. This will return to the tank once the engine is started. To dry crank the engine, disconnect the ignition coils and turn the engine over until it produces oil pressure and oil is returning to the oil tank.

d. Once the engine is producing oil pressure and the oil is returning to the tank, re-connect the ignition coils and turn the ignition on. Start the engine with no throttle, then increase the engine speed to approximately 2,000rpm – 3,000rpm. Check the oil pressure - it should be a minimum of 60 psi. e. When the engine coolant temperature reaches 50°C, hold the engine revs at 4,000rpm for a few seconds (this allows the scavenge system to clear oil from the crankcases) and turn the engine off.

WARNING – RADIATOR COOLING FANS ARE NOT FITTED AS STANDARD. DO NOT LET THE WATER TEMPERATURE EXCEED 90°C WHEN WARMING THE ENGINE TO CHECK THE OIL LEVEL.

f. Immediately check the oil level, it must be between the top two marks on the dipstick.

Re-Starting

a. Ideally, the engine should be started 45 minutes prior to going on track. Turn the engine off when the coolant temperature reaches 85°C and allow heat to soak into the engine. Restart 10 minutes before going on track and get the coolant temperature to 75°C.

b. The oil level should be checked after every hour of running, and it should be topped up to the level indicated in these instructions.

Service Intervals

Engine Oil and Oil Filter

The engine oil and filter should be changed after every 5 hours of running.

Oil Filter Fitting Procedure

1) Apply a thin film of engine oil to the sealing o-ring on the oil filter. 2) Screw the filter on to the engine by hand, until the o ring on the oil filter contacts the engines surface. 3) Using an oil filter tool (shown in picture), turn the filter another 2 turns. 4) To prevent the oil filter coming loose during operation, a jubilee clip must be fitted around the oil filter. The adjuster screw housing of the jubilee clip should sit against the bolt in the crankcases, as shown in the picture. It should be located hard up against the right hand side of the bolt, as you look directly at the oil filter. If it is on the wrong side, it will not effectively prevent the oil filter from coming loose.

Fuel Filter

The fuel filter should be cleaned after every 20 hours of running or visually inspected - especially if you have recently fitted a new fuel tank, are experiencing fuel starvation, or a drop in fuel pressure. Air Filter The engines air filter should be inspected before every race. It should then be cleaned and oiled as per the manufacturer’s instructions and should be replaced as required.

Engine Returns

When returning an engine to RPE for a refresh or repair, the engine should be removed from the vehicle and be externally clean. Please follow the procedure below.

• Flat packed metal crates can be collected from your local distributor, alternatively you can drop off your engine at your distributor and they will process the engine on your behalf.

• All engines must be drained of fuel, coolant and oil.

• Tilt the engine, so that the drain bung on the sump is the lowest point of the engine and leave for 3 to 5 hours.

• Bung all oil, water and fuel inlets and outlets.

• If possible shrink wrap or seal the bottom end of the engine to catch any residual fluids.

• Ensure no previous shipping details remain on the shipping container as this may cause delays with shipping and customs.

• Locate the engine securely in a crate.

• Add packaging to secure the engine.

• Additional items (ECU, throttle bodies etc) must be packaged and secured.

• Secure lid and affix address labels to lid and side of crate (minimum of 2 labels)

To keep within the warranty rules, the ECU should always be returned to RPE with the engine. This is for two reasons:

• Data can be checked.

• Engine hours can be reset on the ECU. In the event of an engine failure:

• RPE should be contacted and the ECU’s data should be downloaded and e-mailed to Radical Performance Engines technical: ……………….. (technical1@radicalperformanceengines.com).

• Debris may have transferred to the oil lines and cooler. An exchange oil cooler MUST be fitted and the oil lines flushed thoroughly with non-water based cleaner (Such as Petrol or Jizer cleaning fluid). The cooler can be purchased either from Radical Performance Engines or your local Radical distributor. If in good condition, you will only be charged the cost for ultrasonically cleaning your exchange oil cooler.

Failure to carry out the above will result in your engine warranty being void and no claim can be made against it. As soon as your original engine is repaired and fully refreshed you will be credited/invoiced for the work/parts required. RPE do not cover the cost of removal and refitting of the engine, any third party costs or replacement of fluids. RPE also offer a range of optional services when having your engine rebuilt. These are:

• Injector testing and cleaning

• Heat exchanger strip and clean

• Oil cooler ultrasonic cleaning

Balancing Throttle Bodies on a 4 cylinder

Life Racing ECU

1) Connect a laptop to the car and load PTMon. (This displays the engine

sensor readings) 2) To achieve a base setting the throttle needs to be fully closed. To ensure it

is, wind the idle adjuster screw out whilst watching the TPS reading displayed in PTMon. The value should reduce as you wind the screw out. Once the value stops reducing, the throttle is fully closed.

3) Set the TPS value to 2.0. To do this, loosen the TPS using a 3mm allen key, as shown in the picture. Once loose, turn the TPS until its value shown on PTMon is 2.0, and re-tighten the securing screws.

4) Using a 3mm allen key turn the idle adjuster screw, until the TPS

value is 4.0. 5) Now you are ready to start the engine. Check the engine oil, water and

electrical connections. (Especially if it is a new engine installation). Once you have confirmed these are OK, start the engine and let it idle. Make sure the engine temperature is maintained within its operating parameters. Do not allow the water temperature to rise above 90°C.

6) Place the syncrometer in throttle body number 3. This body is not adjustable it is your base which the rest of the bodies need to match. The syncrometer will normally read between 5 and 7.

7) Place the syncrometer in the other bodies, using a 7mm spanner and 2mm

allen key (as shown in the picture below) adjust the other bodies to match the reading from body number 3. Please note that turning the adjuster clockwise opens the body. To adjust, loosen the 7mm nut and turn the adjuster in the centre. Once the reading is correct, lock off the adjuster by tightening the 7mm nut and holding onto the 2mm allen key to stop it from moving. When balancing match the reading on cylinder 3 and 4 with the adjuster, then match 1 and 2 finally use the centre adjuster to match both sides.

8) Once all four bodies give the same reading on the syncrometer, the bodies

are balanced. Give the engine a couple of small blips and check the TPS value returns to 4 and all the throttle bodies read the same on the syncrometer.

1) Connect a laptop to the car and load Easimap. (This displays the engine sensor readings)

2) To achieve a base setting the throttle needs to be fully closed. To ensure it is, wind the idle adjuster screw out while watching the TPS reading displayed in Easimap. The value should reduce as you wind the screw out. Once the value stops reducing, the throttle is fully closed.

3) Set the TPS value to 0.13. To do this, loosen the TPS using a 3mm allen key, as shown in the picture. Once loose, turn the TPS until its value shown on Easimap is 0.13, and re-tighten the securing screws

4) Using a 3mm allen key turn the idle screw up until the TPS value is 0.19 to

0.20. 5) Now you are ready to start the engine. Check the engines oil, water and

electrical connections. (Especially if it is a new engine installation). Once you have confirmed these are OK, start the engine and let it idle. Make sure the engine temperature is maintained within its operating parameters. Do not allow the water temperature to rise above 90°C.

6) Place the syncrometer in throttle body number 3. This body is not adjustable it is your base which the rest of the bodies need to match. The syncrometer will normally read between 5 and 7.

Driving Techniques for Cars with an RPE Engine

Paddle shift cars:

• The clutch is sharp, and needs to be let out slowly whilst the car is stationary.

• To pull away, engage 1st gear, with the clutch fully depressed, raise the revs to 2500 rpm, and slowly release the clutch.

• When the car is moving slowly, it is advisable to use the clutch on the way up and down the gearbox, and when changing up and down from 1st to 2nd at speed. However whilst on track, at racing speed the clutch is not needed, and you can keep the throttle open on up changes.

• Optimum revs to change up gears are between 9,500 and 10,000 rpm, as this is where the engine reaches its peak performance.

• To change down you should wait until the revs have dropped to around 7,000rpm.

• The slick tyres on the car, the brakes and the engine will take a few laps to warm up. Grip is greatly reduced on cold tyres, so it is important to take this into consideration, and slowly build up your pace.

• The cars are at their best when driven smoothly, so gradual application of throttle, brakes and steering is best.

• Throttle and brakes must be applied separately, never together.

• All braking, wherever possible, should be done in a straight line along with down changes. If excessive brake pressure is applied whilst increasing steering lock this will unsettle the car and possibly cause the car to spin.

• The car should be in a straight as possible position before the throttle is applied, with minimal steering lock on. If excessive steering lock is on whilst applying throttle, this will unsettle the car and possibly cause the car to spin.

• It is important not to change gear while experiencing wheel spin, especially in the lower gears.

Cars on stick shift:

• All of the above applies, apart from the gear change technique.

• To change up and down the gears at low revs the clutch must be used.

• To change up the gears at racing pace, use of the clutch is not necessary, but can be used if preferred. To change up the gears, you need to lift off the throttle, and pull back on the gearstick to engage the next gear. You can then let go of the gearstick and it will return back to its central position

To change down the gears whilst applying the brakes, you need to depress the clutch and push the gearstick forwards to engage a lower gear. As the gear is engaged you can release the clutch and let go of the gearstick, which will return to its central position. To come down multiple gears just repeat this process, making sure the clutch is depressed for each down change. Should the car spin Due to the design of a motorcycle engine, if it is forced to turn over backwards the starter system can become damaged. It is important therefore that if the car is in a spin situation, the clutch is depressed as a matter of urgency, to reduce the risk of damaging the engine starter system.
