Message: [QUOTE="wetnsloppy4x, post: 236802, member: 395"] So 2.46ms is the max pulse width in the ECM? If that is the case, I think a real world race tune p/w at a real world race tune RPM redline would be a little more informative. I'm talking a tune that is set up for "perfect world" conditions using the right size of stick and nozzle, not a bandaided tune trying to compensate for less than optimal parts for the setup. Don't get me wrong, it's no brainer that the larger nozzled injector will empty quicker given the same p/w. I think it would be usefull info to know where the crossover point is in relation to injector size and p/w. Say your tune needs a p/w of 1.8 ms @ 4000 RPM for an optimal injection event (made up numbers). What % of nozzle does the 175cc need to empty in that time. What % nozzle would a 190cc to empty in that time? What about a 205cc, and so on. See what I'm getting at? The way I understand it, the optimal p/w is the optimal p/w regardless of injector size. The injection event needs to happen in the optimal desired window of crank angle regardless of injector size. What we need to know is what each partiular size of injector needs for a nozzle size in order to empty in that optimal window and still maintain good atomazation. A guy can throw 100% nozzles at 190cc sticks all day long, but does it need that 100%? Am I articulating my thoughts in a way anyone else understands? [/QUOTE]
