A general formula to roughly determine what size injectors to use is as follows:

cubic centimeters/minute = pounds/hour X 10.5

pounds of fuel per hour per injector = expected hp X 0.55/ # of injectors

ok so lets say 430 to the wheels:

430 hp X .55 / 4 (number of injectors) = 59.1

59.1 X 10.5 = 620 cc

so for 430 hp you would need a 620cc injector maxed out at 100 %

575 cc max out before 400 hp.

these are rough giude lines but guide lines that work. Usually people go one step larger for future improvements.

This kit has all the no-no's that Corky Bell points out. Raising fuel pressure according to boost is an ok method up to about 9 psi not 20.

I am sure inline pro is a great company that builds great cars at an amazing rate. But this kit scares me.

How many people have posted that when they cross the 320 h.p. line that
that the fmu method just doesn't cut it. The car runs like crap. Hmmm
studdering below 4000 rpm....maybe to much fuel down low ...maybe can't get it tuned correctly with the fmu and the afc. Fmu and afc are cost effective options when keeping the hp under say 320 hp.

 

Its about time some one see's my point of view man those people from honda-tech.com are blind as a bat. to my fellow s2ki peeps who really know what they are talking about ....

 

Another way to know what kind of injectors you need, by doing this: you want 400rwhp u do 400x2 = 800+cc injectors.

 

I am running 7.5 psi on 550cc injectors and they are at about 80-85% capacity.

 

We got one of the best NA engines... why cant we be happy

I'd personally rather tweak the car with an NA setting than run boost *shrug* but thats just my own thing

 

I've got the question for you. Have you ever sat in or driven a turbo'ed car?

Only when no one is looking.

 

maximum boost
