In this, episode 150 of PowerTec 10, DV describe how he and his crew, Colin and Hugh built a ground effect 'tunnel' sedan racer. This 'tunnel' concept was seen on this car, a Ford Anglia, six years before a 'tunnel' car was seen at Indianapolis. Its success was measured by the fact that on faster corners it could out corner even the best of regular type race sedans by as much as 100%. If the rules allow and you want that dreads none of it's competition here is how it was done.
