I'm going to start with 38 > lb injectors at 38 PSI - should be good for about 230 HP at 80% > duty cycle and 0.5 BSFC. Would also be good for ~245 HP at 44 > psi. Note that if NA these will not be working very hard at A couple of interesting points for me here: 1. There's a direct corrolation between fuel PSI and volume of fuel released. Obvious, I guess, but I hadnt thought about that. So - lowering my PSI might get me into the right range??? 2. People talk about 550cc/min and 38lb injectors. I presume its a simple conversion from cc to lbs, but the mixed units arnt helping. What are the 550cc injectors in lbs? John Slade
