Time for a new project!
I own a Vectra B with suspension and brake modifications. I also fitted a Rotrex supercharger with Omex standalone management. More Information on www.projectvectra.com (website needs updating I know). The only problem is, to get it to show standard it's going to need a full re-spray and other bits doing. That cost effectively bought me the Vectra C! I made a lot of mistakes with the old car and want to modify the Vectra C in the same way, this time without the mistakes!
I have owned the Vectra C since November 2010, and along the way have sorted out any problems with the car.
In the long run I would like to transfer the supercharger and management to the newer car, but for now this thread is dedicated to the progress of preparing the Vectra GSi for bigger power.
The FIRST thing to do before any modification is carried out is to get an initial power run. That gives me my starting point. From here I will know if any modifications have increased or decreased power output. The power run will also tell me if there are any other issues that the Tech 2 equipment hasn't picked up.
So, here is my dyno graph.
