Is it time for bigger injectors?

Dyno'd my car awhile back and came out with 380 rear wheel HP.....I was doing some reading and came across an injector article that said anything from 385 to 440 FLYWHEEL horsepower should have 30lb. injectors. Based on my calculations I have 430-435 flywheel horsepower.....soooo, any thoughts on what I should do?

If you don't have 30's already I would go with 30's or maybe even 36# ones at this point

my car doesn't act like it's starving for gas...am I losing HP and/or ET, MPH with smaller injectors?

Re: Is it time for bigger injectors?

I'd be curious to see what your A/F ratio looked like at the top end. I'm scared to death to run my 383 hard with 24# injectors....and until I get a tune done with my 42#, I'm laying out of it.
