The dyno runs were run in 4th gear and the car made peak power at 5900rpm.The car was restricted by a [shizzle]ty cooler(2inch thick) and a 2,5" exhaust,as we turned the boost up to 16psi the car made 3 kw more.We just finished building a new engine(same specs as b4) and hopefully with new exhaust and a few other things i can hit 200kw with 15-16 psi.
I made the plenum and my mate did the welding,its easy to do,just keep the runners and bolt the new plenum on top.
here is the pic
