Weight should not effect results using any form of wheel dyno. Weight being factor which affects acceleration, rather than developed power. Hence the disparage in respect of quarter times verses maximum speed, recorded for the SVX.
That said, tyre inflation is a very important component in respect of error, made more, so the heavier the car.
