    4-VALVE HEAD - OPTIMUM PORT VELOCITY??

    i like you're idea, one thing I have always thought about is trying to maintain a constant port cross-sectional area, the best port velocity is going to depend on your application and design, start modest and get bigger while testing power output. Use numbers as an initial test, when it comes to...

    Best bore-stroke ratio?

    hi could it be that the best bore to stroke ratio is not as important as the best rod length to stroke ratio? by having a higher ratio you increase the dwell the piston sees at the top of the cylinder and basically changes the sinusoidal graph of the piston movement. I also recall that this will...

    Oxygen sensor and chip-tuning

    Hi I was just wondering why you couldn't add a diode on the oxygen sensor? Germanium diodes have a forward voltage drop of around .3v. This would show a lean condition at the computer and it would add more fuel to the engine. The computer would operate as if the air/fuel ratio is 14.7 but would...
