Must-see: Ferrari F1 312B2 Dyno Video. Absolutely glorious sound track. Incredible!.

This was a standard rebuild on an existing engine platform with no additional modifications for power. The primary consideration was reliability and clean running.

After the first rebuild, it was run on a chassis dyno and produced 289 HP @ 9000 rpm. After the second rebuild (re-fresh), it was run into a new Superflow Powermark dyno with a definite improvement (365 HP @ 9,800). Most of the improvement was due to fuel curve tuning on the Lucas mechanical injection system and ignition optimization. While not the most powerful vintage F1 engine, it has been very reliable and smooth.
