Preparation for shake-down
Before your SR3 RS leaves the factory it is thoroughly inspected, the
suspension is set on a flat patch to factory recommended settings and
the car is run-up and fully checked on our rolling road dynamometer.
Despite this, it is essential that before taking to the track, you carry out
a thorough spanner check, paying particular attention to all hoses,
connections and suspension fixings, brake bias adjuster etc.
Check engine oil level
The oil level in the dry sump tank must be checked using the dip stick
supplied. The level must be maintained between the top two marks
when warm (a minimum of 40°C oil temperature), and between the
bottom two marks when cold. The level should be checked AFTER
running the engine, and holding the revs at 4,000rpm for ten seconds,
to allow the oil to be scavenged. The engine should be turned off to
check the level. (The sight-glass in the side of the engine should
be ignored.)
Only use Radical-recommended oil which is formulated to run in the
integral gearbox and clutch, as well as the engine. Recommended
synthetic-based racing oil is available online.
NOTE: The oil level on pre-2009 cars fitted with the Powertec-Suzuki
wet sump engine, should be no lower than three quarters up the
sight-glass, with the car on level ground and the motor warm and
running. The sump is baffled and the oil takes some time to settle. Later
wet sump engines are fitted with a dip stick in the top of the engine to
aid checking oil levels.
Checks before driving your Radical
WARNING!
Do not rev the engine to more than 4,000rpm until the
oil is above 50°C. When cold the oil can run at
excessive pressure, which may damage the engine.
Radiator cooling fans are not fitted as standard.
Do not let the water temperature exceed 90°C when
warming the engine to check oil level.
Check other fluid levels
In the brake and clutch master cylinders, use only Radical approved
high temperature racing brake fluid which is available online.
The engine cooling system uses a 50:50 anti-freeze/water mixture. The
level should be to the top of the swirl pot.
The Powertec gear drive system should be filled with
Radical-approved gear oil, available online, to the level of the side
inspection plug.

A comprehensive manual is included on the CD that is supplied with
the dashboard system, or is available from the Radical technical
department.
Checks before driving your Radical
The position of the pedals can also be adjusted by a) adjusting the
pedal face, b) adjusting the pedal angle and c) by moving the pedal
pivot shaft. PLEASE NOTE that c) will require changing the master
cylinder push-rods which are available online.
Manual sequential gear change
The SR3 RS is supplied with the gear lever set to "pull back on the gear
lever to shift up the box" and "push forwardto shift down the box".
By moving the gear linkage rose joint from the lower fulcrum to
the upper fulcrum in the engine bay, the gearshift direction will
be reversed.
If your SR3 RS is fitted with a Powertec pneumatic power shifter, please
refer to driving technique section 10.

Starting the engine
Cold Start: with the engine in neutral, switch on the ignition. Start the
engine with the throttle closed.
Warm Start: depress the throttle a small amount and start the engine.
Running-in
Powertec Suzuki 1340cc motors are filled with mineral oil and bedded
in on Radical’s rolling-road dynamometer. The car should be run for an
hour with the revs kept below 8,000rpm, before being driven at
maximum revs. The oil should be changed to Radical-approved fully
synthetic racing oil, available online, after six hours of running.
Powertec Suzuki 1500cc motors are fully run-in and filled with fully
synthetic racing oil, and can be driven at race speeds after completion
of 'shake down' where temperature and oil pressure have been
observed.
Shake down
Carry out several installation laps while watching the temperature and
pressure read-outs. Return to the pits regularly, and thoroughly check
all fluid levels and around the engine and cooling system for leaks.
Driving your Radical
WARNING! Do not run the engine under load if:-
WARNING! Do not drive the car until the engine is at
a minimum 60°C water temperature and minimum 50°C
oil temperature.
Do not run the engine in-gear with the wheels off the
ground. This will damage the gear box.
a) Oil temperature is below 60°C
b) Oil temperature is above 130°C
c) Water temperature is below 60°C
d) Water temperature is above 100°C
e) Oil pressure when up to temperature at
4,000rpm is under 50psi.
Should you accidently run the engine under load in any of these
situations, contact Radical’s technical department to arrange for the
data to be emailed for analysis.
The oil pressure when the engine is started from cold should run at
approximately 90psi at 4,000rpm. When up to temperature the oil
pressure should read 60psi at 4,000rpm.
Maximum engine revs: 10,500rpm
If over-revved from 10,500rpm-12,000rpm for more than two seconds, in
any one hour of operation the engine will require stripping for
inspection and repair, at the customer’s cost, prior to any further
running. (Any over-rev will be recorded on their ECU histogram.) If
revved to over 12,000rpm for any length of time, the engine will require
stripping for inspection and repair, at the customer’s cost, prior to any
further running.
The rev limiter is set to 10,500rpm. Persistent use of the rev limiter will
damage the engine.
It is important to log the number of hours the engine is run. Under race
conditions, the engine should run for no more than 40 hours before
being returned to the factory for a rebuild. Engines which are not
raced, regularly cover over 90 hours without requiring attention.
9

Bedding-in brakes
The car comes fitted with carbon metallic brake pads. To bed in the
brakes and achieve maximum stopping power, a film of carbon must
be transferred to the discs; gently apply brakes six to eight times at
medium speed. Increase speed to simulate race conditions, and
apply brakes hard a further six to eight times.
Allow brakes to cool for 15 minutes. Do not apply brakes
whilst stationary during the cooling down period. Use only
Radical-recommended brake pads, available online.
Brake bias settings
Set central to two turns towards the front (clockwise on the dash
adjuster). Further adjustment can be made to suit individual circuits and
tyre configurations. Adjust bias to the rear in wet conditions.
Manual gear change
If you are unfamiliar with a sequential shift car, it is recommended that
you change gear using the clutch when going both up and down the
gearbox. Once you have become familiar with the technique,
changing gear up the box can be achieved by lifting the
throttle quickly and simultaneously 'snicking' the gear in, without
depressing the clutch. On down changes it is imperative the driver
depresses the clutch and raises the engine speed before engaging
the gear. Smooth gear changes can be best achieved by using the
'heel-and-toe' technique. Only change down one gear at a
Driving your Radical
time, releasing the clutch pedal between gears. As with any
dog-engagement gearbox, aggressive gearchanges will damage the
gear dogs, which will result in gear engagement problems. Only use
a maximum of 7,000-8,000rpm while getting used to driving your SR3.
If you accidentally down-change instead of an up-change, you are less
likely to over-rev the engine. If you do over-rev the engine, make your
way slowly back to the pits. If you have revved the engine over
12,000rpm, switch off and return the engine to Radical for inspection
immediately. The Radical dash will display the maximum rpm.
Paddle-shift gear change
If your SR3 RS is fitted with the Powertec, steering wheel-mounted
paddle-shift system, it is possible to flatshift when you are changing up
the gearbox, and to have clutchless downchanges. You will need to
use the clutch to engage first gear, to pull away from stationary, and
when stopping the car.
To select first gear, depress the clutch and pull the left-hand paddle. To
change to second gear you then use the right hand paddle. It is
recommended to use the clutch when changing up the gearbox, from
first to second, at all times. Once you are on the track, and up to track
speed, then it is just a matter of accelerating, and pulling the right hand
paddle. A very slight delay will be felt as the engine ignition is cut, and
the system selects the next gear.
When changing down the gearbox, simply brake where you need to
and operate the left-hand paddle. The system will blip the throttle for
WARNING If you spin, depress the clutch quickly or
you may damage the starter motor.
NOTE It is also recommended that gearchanges
are not made while experiencing wheelspin, such as
exiting slow speed, hard acceleration corners, as this
can damage the gearbox.
10

Driving your Radical
Powertec engines in the USA should only be run on racing fuel such as
cam2, or a minimum of 108 octane, available at most American tracks.
Fuel filter
The fuel filter will require changing after the initial run. It is located at the
left-front corner of the engine bay.
you and select the gear. When changing down from second to first, it
is recommended to use the clutch.
The gearchanges should feel smooth. If any mis-shifts or harsh
gearchanges are experienced, then it is recommended to return to the
pits and investigate the problem. Most gearchange problems won't
go away with more driving.
Neutral on the gearbox is between first and second gear. To select
neutral with the paddleshift system, it is best to change all the way
down to first gear and flick the right hand paddle (with the clutch
depressed). This may have to be repeated this several times to
engage neutral. (Alternatively switch the engine off, leave in gear and
attempt the above with the engine off).
Driving technique
Ensure that the tyres and brakes are fully up to temperature before
pushing hard.
The Radical SR3 RS has phenomenal braking performance and will
carry considerable speed into a corner. Practice braking hard, but
come off the brakes smoothly and concentrate on carrying speed
into a corner. On exiting the corner, the throttle should be fed in
progressively. Driving smoothly is the secret to quick lap times.
Fuel
Powertec Suzuki 1340 engines may run on 98 octane regular unleaded
fuel. The Powertec Suzuki 1500 engine should only be run on Super
Unleaded 98 octane, or 100 octane race fuel.

Air jacks
Cars fitted with air jacks are supplied with an air lance, which is
inserted into a valve at the rear of the car. The lance requires
connection to a bottled air supply, and the pressure should be
regulated to 250-300psi.
Suspension set-up
The Radical SR3 RS' suspension is set up at the factory, but the final
settings should be determined by testing for driver preference and
the particular circuit. Try to check the tyre temperatures for balance
across the contact patch within one minute of a fast lap. The inside
edge can be 10° – 15°C higher than the outer edge on
Radical-approved Dunlop tyres, on the front and 5° – 10°C higher on
the rear. Temperature should be close to 100°C, while temperatures
over 110°C will cause damage.

Suspension pre-load
Setting the front pre-load is acheived by raising the car front until the
front wheels are off the ground. Unwind the spring platform until the
spring is loose then retighten until finger tight. Only tighten three full
turns beyond the point at which the spring ‘grips’ in its seat. Front
pre-load stops the front of the car from touching the ground, at higher
speeds circuits, more will be required, and at low-speed circuits,
less pre-load. Three turns is suitable for most tracks. A more
comprehensive handling guide can be obtained by emailing
[email protected]
Note: Measure the ride height at front of the chassis and at the seat
back bulkhead, (below rollover bar) with the driver seated and 15
litres of fuel in the tank.
WARNING! Running tyres below the recommended
pressure may lead to tyre damage or failure.
WARNING! Do not drive at speeds over 120mph until
your tyres are up to temperature and pressure.
12

Corner weights
For maximum performance, your Radical should have the corner
weights accurately set with the driver in situ. The procedure is
as follows:-
1 Position the car on a flat, horizontal surface.
2 Equalize all tyre pressures to 30 psi.
3Take all readings with driver in-car, or equivalent weight in
the seat.
4Remove bolt from one end of the front and rear Nik-Link, and
adjust shocks to full soft.
5Ensure the factory springs have three turns of pre-load (new cars
will have this done at the factory, and the top platform marked
with a ‘3’). See left to set pre-load.
6Set the ride height at the front by adjusting the push-rods
7Set the ride height on the rears by adjusting the spring platforms.
8 Set the camber front and rear.
9Set the toe-in front and rear.
10 Put car on corner-weight scales, and set corner-weights by
adjusting rear spring platforms. It is usually difficult to achieve
identical settings on each corner. Ensure that the sum of the
diagonal weights are as near as possible.
11 Re-check ride height and diffuser height with the bodywork on.
12 Lock spring platforms.
13 Refit Nik-Links, rear anti-roll bars, reset shocks, and set tyre
pressures.
14 You are now ready to "rock & roll".
Ride height with passenger
The ride height may need increasing when carrying a passenger. The
ride height may be increased up to 100mm at the diffuser, by adjusting
the spring platforms. If you intend carrying a passenger for the
majority of the time, the above procedure should be carried out with
him/her also in the car.
Preparing your Radical
Triple Adjustable Intrax Damper (option)
High speed compression (bump) low-speed compression (bump)
and rebound can be adjusted independently, enabling a more refined
set up to be achieved.
1Red adjuster on canister: High-speed compression, 50 clicks turn
clockwise for more damping.
2Small 4mm screw: Low speed compression, 18 clicks turn clock
wise for more damping.
3Black adjuster on spindle eye: Rebound, turn clockwise for
slower rebound (stiffer).

Gearing
The Powertec gear drive system incorporates a reverse gear, a torque
biasing limited-slip differential, oil pump/cooler and changeable
gear ratios.
Gear Drive Unit - ratio change
Tools required 5mm allen key, 34mm socket, 42mm socket, 13mm
spanner, long extension bar or impact wrench, torque wrench,
electric heat gun (optional), 28mm spanner, gasket sealant, gasket
scraper and Loctite 243 threadlocking compound.
a) Drain oil from unit through lower drain plug.
b) Remove level plug from gear cover plate.
c) Remove the eight M6 cap screws and washers from the gear cover
plate and separate from the unit. Care must be taken not to
damage the 'O'-ring seal located in the groove in the main case.
The gear ratios can now be accessed.
It is important to note at this stage that the front 34mm retaining nut is a
conventional right-hand thread and is removed in a counter-clockwise
direction. The rear 42mm retaining nut is left-hand thread and is
removed is a clockwise direction.
d) Both the retaining nuts are treated with a medium strength thread-
lock such as Loctite 243. It may be necessary to lightly heat the nuts
with a heat gun.
Preparing your Radical
e) The nuts can now be removed with the correct size socket and a
long extension bar, or an impact wrench on a low setting. It may
require some force to overcome the locking tabs on the nuts.
f) Once the nuts have been removed, the front and rear gears, the
roller bearing and the spacer can be removed from the shafts.
(Note the orientation of all these parts for re-fitting.)
Radical Gear Drive Unit ratios
14
WARNING! Do not use a blowtorch or other high
temperature heat source as this may damage
the shafts.

g) Select the new ratios and install on the shafts (the shoulder on each
gear towards the centre-line of the unit) and re-fit the spacer and
roller bearing.
h) The threads on each shaft should be clean and coated in Loctite
243 or equivalent before the nuts are fitted. Both the 34mm and the
42mm nuts should be torqued to 45ft/lb before the locking tabs
are punched into the respective grooves.
i) Clean the surfaces between the cover plate and the main unit. Fit
the rubber O-ring seal into the groove on the main case. Apply a
thin film of gasket sealant to both surfaces, this also helps to hold
the seal in place during the fitting process. Allow time for the
sealant to cure.
j) Re-fit the cover plate and tighten the M6 cap screws and
washers evenly.
k) Replace the lower drain plug, remove the upper plug and refill the
unit with Radical-approved synthetic transmission oil until it runs
from the level plug on the cover plate. A gear drive system
including cooler will hold about 1.5 litres of oil.
l) Re-fit the level plug and the upper plug and check all bolts
and fittings for tightness. Check the unit for leaks after the first
short period of running. Remove the cooler return pipe (top
fitting) and check the oil is being pumped round the system as the
wheels turn.

Component 'lifing'
This chart gives the recommended life expectancy of components
under 'normal, on-track racing conditions'. If some of your racing time
is done 'off-track' or you hit kerbs, pot holes or other cars - hard, then
you will need to consider reducing the timescales recommended. On
the other hand, more 'gentle' trackday use will obviously extend the
recommended time!

One new addition to the list is the wing support stays, the life of these
is greatly shortened if the wing is used to push, and particularly pull the
car around in the pit lane, garages and trucks. It works perfectly to
support the wing and the downforce generated in the direction
intended, and not at an angle to the centre-line of the vehicle.
