Well, the cylinders are 109mm Mahle's. The pistons are by Streck. Porsche no longer uses the Mahle pistons. We did not know this until we ordered from Germany. Due to all the problems with this engine it was taken down all the way. Good thing because the main bearings were 50% shot after only 25 hours on the engine. The car is a 91 cup car brought up to 94 specs. Management is provided through MoTec. Fuel injectors sent out and mapped. Don't know what else anyone would like to know. The engine is so wildly tuned that on the dyno before the engine rebuild, at 4K rpm it was putting out about 130 HP. 325HP at 7K. Below 4500 the car just coughs and spits. The dyno is the one they bolt up to the axles.
So for the first session during break in I need to keep the car between 4500 and 6K and with 6 speeds. Man, try to say DIFFICULT.
