Arouse the DAMPFHAMMER!
Actually the processor of my calculation engine is occupied with some crazy 2-Liter engine stuff. While this check this out...I would be interested to see what that looks like
This is a very simple setup with an 12.5:1 CR. Despite the air box it full fills the racing rules. I am not sure about the power offset in measurement, as this guy is a DC distributor. But from the torque graph, where normally beyond 7 krpm the line knocks down a bit more as usually is supplied by the different valve timing. According my simulations some head work would be necessary or it was used the RSP head at least.
