[QUOTE="FISHTAIL, post: 9887943, member: 19212"] FYI, 400 rwhp is close to 500 at the flywheel (well, maybe more like 470 assuming a 15% loss through the drivetrain). Those injector load values are not rwhp ratings, they are based on flywheel horsepower. So, if he does actually make 400rwhp then a 36-39# injector will be needed, depending on what his drive train loss actually is. The only point I was trying to get across is a 30# injector is not going to be big enough for his intended power level. If your going to spend the money on injectors, better to error on the side of caution and get something that can support your target number plus a little more. Everybody knows a car is never done, and it sucks to have to keep replacing parts un-necessarily. [/QUOTE]
