Cummins 855 Big Cam 1st start after rebuild
my 1st engine teardown and rebuild at OTC
Ferrari F1 312B2 Dyno Video
This was a standard rebuild on an existing engine platform with no additional modiﬁ cations for power. The primary consideration was reliability and clean running. When we originally received this engine for rebuil (we have done it twice now over a period of years), it had broken the timing gears so we didn't have a baseline Dyno run. After the ﬁ rst rebuild, it was run on a chas- sis Dyno (our original DTS engine Dyno couldn't handle the quick rpm changes) and produced 289 HP @ 9000 rpm. After the second rebuild (re-fresh), we ran it on our new Superﬂ ow Powermark Dyno and saw a deﬁ nite improvement (365 HP @ 9,800). Most of the improvement was due to fuel curve tuning on the Lucas mechani- cal injection system and ignition optimiza- tion. While not the most powerful vintage F1 engine, it has been very reliable and smooth.
Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 118 cycles per second is an amazing sight (and sound)
