Re: Lb9 question
Stock injectors are 19lbs on a 305 tpi. Using the calculator, adjusting pressure and pushing the duty cycle dangerously high, you'll get approximately 300+ish hp. But that's using a calculator and not exactly what happens in real life so take it or leave it. http://www.rceng.com/technical.aspx

Re: Lb9 question
Ok... I read something about 274 with the fuel pressure bumped up and like 245 with it stock pressure...but wonder what mods would get me there? I can't imagine it taking much.
