I'm thinking about getting some injectors. Wondering what is good and what other people are running. I'm thinking something around 90hp or 140hp. I think 140 are 5x14? and 90 are 5x12? Is this correct? Where would 5x13s fall in? Right now I have an HX40 but will upgrade when needed, 4000GSK, #10 Plate. Shooting for 500-550 hp and would like to buy an injector I can use with my current setup as well as my goal. Looking for ideas, thanks.
