hey guys i met a engineer and he gave me some formulas for picking the right injectors.
if i want to make 240 hp i would need 45 lbs injectors and 43lbs for 220 hp
what r yr thoughts on this?

seems your engineer friend is a little off since 30lbs are good for 200 hp, 37lbs would be around 220-230ish safely to assume, i would say 45lbs would be good for alomost 275+ hp. Theres a calculator on the web at many companys that you can figure these comparisons out at. All of the above info is from the top of my head atm. (should be close)

It depends on what fuel pressure your running the injectors at. 30# injectors need around 85 psi fuel pressure to sustain 220 hp. While a 42# injector only need 45 psi fuel pressure to sustain 220hp.

www.sdsefi.com has a chart in the tech section on what injector flow rates can support what HP.




O noes!
