General Sa
fety Regulations


GSRs



Each car, regardless of class or category, must complete and satisfactorily pass inspection of a qualified
Tech S
crutineer
before being allowed to make a trial run or participate in any event
.

Throughout this Appendix, a number of
references are made for particular products to meet certain specifications (i.e.: FIA, SFI,
SNELL, DOT, etc.). It is important to realise that these products are manufactured to meet certain specifications, and upon
completion,
The
manufacturer labels his
product as meeting that spec. Therefore, except as outlined under SFI or FIA
requirements, any change to the product voids that certification; under no circumstances may any certified product be modifie
d,
altered or in any way vary from the as
-
manufactured

condition; such a practice is in violation of the FIA, SFI, SNELL, DOT, etc.,
program and in so doing voids such certification.

GSR 1:5.1 INTERCOOLER
.

Addition of fu
el to intake air before intercooler prohibited.


GSR 1:6 GASOLINE/ PETROL
.

Gasoline/ Petrol is defined for purposes of this Appendix as a mixture of hydrocarbons only. Non
-
hydrocarbons which do not
increase the specific energy of the gasoline/ petrol are
allowed to the extent that they do not exceed 0.15% by volume and are
blended in the gasoline by the refiner or fuel manufacturer.

Gasoline/ petrol is a good electrical insulator, or dielectric, and its relative effectiveness as an insulator is represented

by its
Dielectric Constant. The average D.C. for the hydrocarbons which comprise gasoline/ petrol is 2.025. This is defined as a
reading of "0" with the FIA/ MSA Fuel Check meter.

erflow capable of spilling water must have a catch
-
can to accumulate the excess
liquids and not leak onto the track. Minimum catch
-
can capacity: 0,5 litre (1 pint) Catch
-
can must be securely fastened; i.e.
bolted, clamped..


GSR 1:9 NITROUS OXIDE
.

Nitrous
oxide allowed . See specific Class Requirements & Specifications. The use of any agents other than nitrous oxide as
part of, or mixed with, this pressurised fuel system is strictly prohibited. All bottles must be securely mounted, and only g
as
cylinders c
ertified for use at the working pressure of the system as a fuel reservoir (also applicable to any vehicle with a
pressurised gas system) permitted. All receiving cylinders should have rupture disc or safety valve to prevent over
pressurisation.

The bottl
e to solenoid supply pipe should be of steel or high quality steel braided teflon hose e.g. Aeroquip and
securely fastened every 6” (15.24 cm) with non
-
combustible clips and fasteners.

All

fittings must be of a screwed sealing type.
.All systems must inclu
de a device which prevents the system being activated before the throttle is operated. A ‘Warning Light’
clearly labelled N2O must be wired into the solenoid circuit so that it is illuminated when the N2O system is armed. Nitrous
oxide
bottle(s) located in

driver compartment must be equipped with a relief valve and vented outside of compartment. System must
be commercially available and installed per manufacturers recommendations. Bottle may not be mounted in engine
compartment.

Advisory check:

Generally
check for leaks whilst the cylinder is turned on to verify gas tight connections. The shut off solenoid
must be checked (with the gas cylinder turned on) by fully opening the throttle momentarily to determine whether N2O is being

discharged (all nitrous li
nes must be disconnected and discharged into the open air, and all fuel solenoids must be electrically
unplugged). The throttle must then be released to about half throttle and held in that position. This should release the sole
noid,
which is activated by

the throttle switch and cut off the flow of gas. Further checks should be made to ensure that any slight hiss
of escaping gas can be detected. All vehicles using a bottle of nitrous oxide must bear a mark in
accordance with
(illustration PIC. 2.)



The ma
rk will be clearly visible and will be located in a place which is not likely to be damaged in the
event of an accident and which is near to the competition number. Venting and refilling of N2O
bottles should be undertaken with extreme caution. External he
ating of bottle(s)
by

electric blanket
for the purpose permitted.
