Here's an idea that would make for a good social occasion, a chance to find out how well your car's performing, and a way of getting a load of Omegas and their owners into Total Vauxhall magazine.
We run a 'dyno' feature in the mag every month: for those not familiar, its the story and pictures of a group of 16 - 24 cars and their owners, assembled at a rolling road workshop where during the course of an afternoon or morning, each car is put through its paces on the rollers to assess its maximum power capability. The tuner who owns the premises generally makes a charge per car, but it's minimal compared to the cost of dyno charges (this is because the event gets them plenty of FOC exposure in the mag).
We've never done an Omega dyno, although we've covered just about every other model (Corsa, Astra, Nova, Calibra, Vectra, Monaro etc, as well as "all star" dynos, which cover any Vauxhall model, but all from specific clubs or regions). Also done VXR only, Z22 SE only etc.
It requires someone from within the club to organise the event and oversee proceedings on the day. We will provide a photographer but the info needed regards cars/owners has to be provided by the organiser.
If this is of interest I can help with advice to get the ball rolling.
