How does HPT read IFR's? or better yet how are the calculated? the sticky just gives values, but no reasoning behind the values given for 60lb injectors.

What about return style fuel system, my understanding is that the IFR should be flatlined (or the same across the board) but how do I calculate what they are needed to be?

 

you calculate your flatlined ifr off of your base fuel pressure. so if your base fuel pressure was 43.5 like the 60's are rated at you would just put 60 across the board.

 

so then why is all the numbers in the flow rate vs kpa map all sub signal digit numbers like 6.34 etc?

 

right click on your ifr table and go down to units. select lb/hr and you should be good to go

 

hahaha you just made my life 10000000x better.

can i say i love you are is that to weird? lol j/k

 

you're welcome
