General
The V8TC Technical
Regulations have close similarities to the existing V8 Supercar
regulations as they are essentially the same vehicle. They also
relate directly to the homologation details of your car model, so it
is important to make sure that you have the correct documentation
(which should be with the car).
At this stage the following changes are required;
A control ECU which is programmed to reduce the engine revs by 500
rpm to a maximum of 7000rpm.
All rear wings will need to be painted black, and require a ‘V8
Touring Car’ decal on the outside of each end plate.
V8TC Category Status/Logbooks
CAMS have advised the following;
A CAMS category classification has been created - V8
Touring Cars.
A car will only be recognised as a V8 Touring Car if it has a proven
history as a V8 Supercar.
When an application is received by the CAMS National office (only
the national office will deal with this category) to transfer the
classification from V8 Supercar to V8 Touring Car, once the history
of the car has been verified, the V8 Supercar log book will be
cancelled and replaced with a new V8 Touring Car logbook.
The preamble of the V8 Touring Cars regulations will state that this
category is only for cars that have a proven history as a V8
Supercar.
The safety cage regulations for V8 Touring Cars will refer directly
to the V8 Supercar safety cage regulations that were in force when
the safety cage was originally certified for the V8 Supercar.
V8 Touring Cars will be included into the eligibility list for Sport
Sedan competitions.
The above process will allow any ex-V8 Supercar that was homologated
with a fitted diagonal windscreen reinforcement bar (as a V8
Supercar) to retain this member.
Note: It is the responsibility of each Competitor/car owner to organize a new logbook with CAMS.
Tyres
A maximum of six (6) new Kumho slick tyres are allowed for a car competing in their first round for Qualifying and Racing (Marked before Q1).
For subsequent rounds, a maximum of four (4) new Kumho slick tyres, and two (2) previously marked slick tyres are permitted. Tyres must be marked before the first qualifying session of a particular round. The V8TC Technical Commissioner will be considered a Judge of Fact in respect to any decisions on tyres.
Fuel
Competitors must only use fuel that complies with the definition of Commercial Fuel as defined in the 2010 CAMS Manual of Motor Sport.
Please note: With the exception of ambient atmospheric air and the specified fuel detailed, no other substance may be added to the intake charge of the engine.
The commercially available fuels generally suitable for V8 Touring Cars are 98 octane premium unleaded ‘pump’ fuel, or E85.
Camshafts
Cars may run with their existing camshafts, provided that the camshaft has a maximum valve lift of .730”
ECU (MoTeC)
A control MoTeC ECU is provided by Tri-State Racing on a rental or purchase basis. The ECU has been pre-set by MoTeC, and it can be checked if and when necessary by race officials.
V8 Supercars and Development Series V8 Supercars use a special MoTeC Engine Management ECU. This “TEGA ECU” is based on the MoTeC M48 ECU but has reduced functionality as well as a fixed rev limit. The limited functionality has been specified to prevent the use of traction control and limit the maximum engine speed. All TEGA ECUs belong to TEGA, so cars that are sold for use outside of V8 Supercars are sold without the ECU. These cars are sometimes fitted with a conventional M48 ECU. Obviously the best solution for V8 Touring Cars is to use an ECU with similar functionality to the TEGA ECU that is also compatible with existing vehicle wiring.
Tri-State Racing Pty Ltd will supply a V8TC ECU based on the MoTeC M48 with similar limitations to the TEGA ECU. The ECU has a dedicated version of software which has been created by MoTeC.
The V8TC ECU has the following features:
Conforms to original wiring system as fitted to V8 Supercars / Development Series V8 Supercars.
Has a fixed rev limit set to 7000 RPM
ECU mapping cannot be adjusted while the engine is running.
ECU software includes a test program to check that the ECU conforms to V8 Touring Car regulations.
Technical Representatives/Scrutineers have software to perform a detailed check on the ECU and record the results.
The ECU has data logging with a fixed logging setup and cyclic memory (512 Kb). The logged data can be downloaded by teams and officials but cannot be erased.
A MoTeC PCI Cable is required to connect a PC to the ECU for communications and configuration.
A standard M48 or M800 is required to carry out any engine dyno tuning using the Dyno version of the software.
