4.0 motor build before/after dyno
Here's the dyno results from our 4.0 motor build on a 997.2 RS. We used all factory parts including 4.0 crankshaft and connecting rods. Stock exhaust, stock airbox, port work with 3-angle valve job, and ECU tuning. 93 octane pump gas. We did this last year, sorry for not sharing the dyno results sooner. It gets very hectic around at the shop with running a race team. 
58hp at the wheels. 40 ft-lb torque. Nice fat power curve. We did a 4.0 build on a GT2 with modified VGT's too!
