G25 A3 smashes 500bhp on the dyno!

Hey guys! This time on TPR the A3 goes on the dyno at Horsham Developments! This was going to be a longer vid with a before and after with the SEM manifold fitted, but life got in the way and plans changed! Dyno vid part 2 will be coming up shortly just as soon as my new gearbox is ready! In the mean time, don't forget to follow us on instagram! www.instagram.com/teamprawnracing
