Message	For high power applications, 740 is the way to go. For ~500RWHP, I think 555's are better than 740's due to fuel delivery precision reasons (and the comparative argument is not moot). This, IMO, is primarily the reason why Nismo has injectors in 555, 615, and 740 sizes. They all cost about the same; if 740's were strictly dominating, the other two won't be offered. Also, look at what Broke_as_**** has to say in this excellent article. Quoting... "So why not get the larger 740ccs just for the hell of it? If you are running injectors that are oversized for your power level it can actually decrease power and increase risk of detonation and engine damage as larger injectors are less accurate in terms of precise fuel delivery."
