after you really increase the air like with all 3 of the mods stated then yes go wit bigger injectors or increase the pressure either way will work but injectors may be more expensive

these equations might help if you kno yuor hp alrdy and some other info.. But REMEMBER PERENTHESSES ARE NEEDED!!!

1st find out if there are specs for stock injectors rated with these units lb/hr or pounds of fuel-per hour, to find out what your stock injectors can supply
take this number (lb/hr) X number of injectors or 4 (hondas anyway) X 2

then take that answer and divide it by .85 or the realistic duty cycle of an injector..this answer is how much hp these injectors can safely deliver

Now for injector sizing
injector size=(engine hp now)xBSFC(Brake specific fuel consumption)which is roughly .50 all over or divided by (the number of injectors) x (injector duty cycle) or.85

if thats confusing this is what it should look like

IS=HPx.50/4x.85 the answer should be pound/hour or lb/hr

now this is based off the standard pressure that most injectors work at around 40 psi


..and a performance fuel pump

to figure out the injector rating with a higher fuel pressure with the same injectors
you will hav to take the square root of the deisred fuel pressure/the stock pressure times the stock injector rating

or
______________________________
\/(desired pressure/stock pressure) X injector rating= new flow rating

then take that last answer, your new flow rating, and substibute it in the 1st eqaution where the old flow rating was and the answer should b the horsepower you are at now..

if its too high lower the fuel pressure

too low raise it..


hopes this helps!!
