    wideband lambda sensor options

    I've always used a bosch lsu 4.9 sensor but just realized that I'm limited to a maximum rich mixture reading of 0.65 This is for a racing application and I don't plan to tune this rich but if for some unknown reason my fuel does run richer than this setting I'll have no idea how rich the...

    Finite Element Analysis

    I've got a clutch assembly for a performance motorcycle. The goal is to reduce the mass but retain strength and durability. My question is if FEA is the best approach to determine the best compromise for the design of the assembly or if there's a different type of analysis that can answer the...

    I did a quick serach but wasn't able to find the answers I was looking for. For vibration damping, would a hollow CF tube perform better than other materials (say aluminium)? What about other types of weave like kevlar/cf vs 100% cf? Is there a chart or a source that has done some testing to...

    Fuel Injection

    I'm a newbie here so go easy on me... My question is this: without any change in duty cycle or duration can I increase the amount of fuel going into the engine by increasing the pressure? This question/answer will help me on my path to answering the big picture questions...
