Introducing Virtual Racer Pro Street, an upgrade to Virtual Racer 1.0/1.1 specifically for competition drag racers.
Working with some of the best Pro Street drag racers in the country we have identified and incorporated the key
vehicle characteristics that set the top Pro Street cars apart from modified road cars.
Virtual Racer Pro Street is an essential upgrade for anyone running full drag tyres or anyone who requires a more sophisticated
level of vehicle setup.
Virtual Racer Pro Street is available FREE to anyone who has purchased Virtual racer 1.0 and registered on the website
(www.virtual-racer.co.uk)

Centre of Gravity Height Adjustment.
The height of the centre of gravity of the vehicle can be adjusted using the slider on the 'Chassis' setup page.
The range available on the slider is proportional to the overall height of the vehicle and the centre of gravity
height is coloured yellow when the value is approximately the default value set by Virtual Racer 1.0/1.1.
Adjusting the centre of gravity height will effect weight transfer. Lower CofG height will help front drive cars retain grip off the line,
and a higher CofG height (to a point) will increase load transfer onto the rear wheels & help a rear drive car.

Driveline Power Loss Adjustment.
Driveline efficiency is defined in terms of a percentage of power loss. Virtual Racer 1.0 calculates the driveline efficiency
based on the other vehicle parameters that are available. If the user knows the driveline efficiency of their vehicle
Virtual Racer allows them to use that value, but if the user wants to use the Virtual Racer derived value then this can be
activated by checking the Auto-Calculate checkbox.

New Tyre Options Available.
Sport, Super Sport and Track Day tyres are available for selection in VR Pro Street as they are in VR 1.0 and 1.1.
Additionally, VR Pro Street includes a drag tyre option allowing tyre dimensions to be input in imperial measurements.
Virtual Racer Pro Street also calculates the effective rolling radius of the front and rear tyres.
The effective rolling radius is the distance travelled per revolution of the selected tyre and can be used to setup
on-board telemetry systems.

Drive Shaft Torque Channel.
The Drive Shaft Torque can be used to judge if the drive shaft used is appropriate to the vehicle. If the drive shaft is
capable of withstanding massively more torque then is produced then the additional mass and inertia in the drive shaft
will be detrimental to the vehicles performance; if the drive shaft is under spec then it is likely to break.
The data can be used for sizing replacement parts, and forms useful information for calculating loads such as those found in the gearbox.

Cumulative or Sequential Power Adders.
Power Adder stages can now be set to work cumulatively where each new stage boosts the previous stages; or sequentially in which case,
as a new stage starts the previous stage ends. This gives flexibility to the user to apply stages in the appropriate way for them.
