    Help Me Decide

    In the worst heat of the summer, I hurt the engine on my '04 LLY. I was pulling the trailer in stop and go traffic with steep hills while grossing over 26,000#. A lot like back to back sled pulls with no cool down between. Water temps were not bad, (220-230 max) but the oil pressure dropped to...

    Dynamite oval pattern injectors

    I'm trying out a set of Dynomite's oval pattern injectors on my truck. It has been some 10 years since I did Anything on the engine, and it shows. Right now I'm fighting stuck bolts and clamps, but discovered my bollows are blown on the up-pipes too. What other joys await me!?

    Machine Down!

    Covers off the VF-3. Several issues all at once. Machine Down! High/Low Gear sensor flaking out. Might require removing the motor and transmission to get to the SOB since it is under the transmission, under the motor. Main Coolant line feeding the head has a big split in the Cat Trac. Wonder...

    Cracked Piston

    Well, it finally happened. Although it was preventable. Two Cast Oval Bowls cracked in a full on race build running well over 1000 HP. The cracks are on the outside of the piston and run from the pin boss up through the steel ring land. Most likely caused by ring stress from loss or reduction of...

    Strange Failure

    I have a customer that has managed to break a piston, but not in a way I am familiar with. The cracks are between the pin and the crown, but do not extend into either. They do not show on the underside either. The is some discoloration of the metal, but not conclusive of overheating. Very...

    Crank Plots

    I've been working on this for a while using the raw data. I finally decided I needed to start making plots to show what I am talking about. The Blue line in these plots represents the time between crank pulses. The variation is visible at all RPMs, but fades in my plots because the duration...

    Cam Gear Loading on Crank

    Been Thinking. Always a dangerous thing when I start thinking. How much torque does it take to make the cam gear slip on the cam shaft? We know the cam gear slips on the cam shaft because of all the damage to the alignment pins on stock cams. Even at stock power levels. The cam gears are...

    Cranks

    So, I've been looking at why cranks fail and what we might be able to do about it. I don't see this turning into a product, so I am going to open this up to the community. I'll open with a simplified model of the first throw of the crank and a representation of only the Max force from a...
