Subject: A day at the Dyno

Well, the Big Chief dyno session has come and gone. Even though we encountered a bearing problem, the 565 proved to be very strong and lived up to my expectations. On the very first pull with no timing. no vacuum pan pump, no collector extensions, and way lean jets, it made 954 HP and 740 ft tq. We made very minor changes and was making a strong charge towards the 1000 HP mark when the #6 rod bearing decided it did not like the previous crankshaft repair that had been made to it, prior to my purchasing the crank (on the 8th pull). Looking back (hind sight is 20/20) I wish I would have sent the crank to a reputable repair shop before installing it. The good news is that we learned plenty to put the Big Chief 565 "WAY" into the 1000 HP teritory without the aid of nitrous. Then the nitrous will add its fury to the fire (count on it)! Also, the damage was minimal enough that the engine can be easily repaired. Am I ever glad that I dynoed!!! If I had not dynoed, there most assuredly would have been a thrown rod that would have put plenty of oil on the rear tires at 140+ MPH, resulting in a nasty crash! I'll keep yall posted on progress. Good luck to all who race the Texans. From what I have personally seen at the Sealy 10.5 shootout, your gonna need it! Later.
