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.

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.
