[QUOTE="ROADWARRIORSVT, post: 3426977, member: 9566"] I was breaking in my F-2M blown [B]97[/B] Cobra, not a 94 as said in the vid. Absolutely the best parts $$$ can buy. It was assembled at local machine shop here in Hawaii. Can't point a finger at anyone until I disassemble the motor and try to see what went wrong. Three pulls at 1/2 throttle, was gonna make three at 3/4 throttle. On the first pull at 5500 RPMs, the throttlebody elbow blows off. I'm guessing that is why all the black smoke at the end? Cranked it up for the next pull and have a clanking under the valve cover. It has now gotton worse. It has Diamond pistons, Manley billet rods, forged crank, etc. So a parts failure at 5500 RPMs is doubtful. I may try a scope to look inside before pulling the brand new motor. Here is a pic of the #8 spark plug I took out during a compresion test. No scrapes, nicks, etc. on it or any of the plugs. Oil pressure is good still. Compresion Test Results Cylinder # 1: 200 Cylinder # 2: 170 Cylinder # 3: 165 Cylinder # 4: 155 Cylinder # 5: 165 Cylinder # 6: 130 Cylinder # 7: 145 Cylinder # 8: 140 (bent spark plug grounding strap) Please "Right Click Save As" [URL=http://www.paradisecruisers.com/videos/Tommy%20Dyno%20Pulls%2003.23.06.wmv]Motor Break In Dyno Pulls[/URL] [ATTACH=full]1310811[/ATTACH] [/QUOTE]
