My installer has 42# injectors he wants to use for my setup on wednesday. I was using an injector calculator and the way i figure it to make 250whp on that size of injector will require me to run them at 96% duty cycle. As far as i know they should be tuned only using 80% duty cycle. Is this gonna be a huge deal? Or should it work okay for a while till upgrade to more power?

well, my installer says 42 should be perfect for a 4 cylinder so i hope he knows what hes talking about. he said the atomization of bigger injectors isnt so great for 4 cylinders with the idle

 

U know when we were first there and i made 235whp on that dyno...I had 42.5lbers...I ran outta injector...that is why i run 60lbers now...I have 20% less displacement and it idles just fine.

I say 60s

 

just go for 60s.

 

i want 60's but im not sure how i can change them if hes gonna charge me for him buying those injectors then buying 60's. ill have to settle for maybe 240whp.
