how much hp can u get out of stock b18b injectors?

 

stock injectors are for stock hp. unless you run fmu.. but thats something you would do 10 years ago. today most choose to chip ecus like hondata aem crome etc

 

FMU all the way

 

I am running stock injectors until I get my 510cc's rebuilt, and I'm boosting 8psi with a little room left. I'm using higher base pressure, walbro 255lph HP fuelpump and tuning with my laptop and wideband and it works great

I would recommend larger injectors and ecu tuning

** Oh yeah, put on your flame suit there are tons of ******** on here **

 

dont boost on stock injectors....
get bigger injectors (whatever size that will best suit ur application). and get a good tune.. and u wont run in to unnecessary problems with fuel later down the road. unless ur planning on making like 180whp... stock injectors are gonna starve ur motor of fuel and ull lean out.... no bueno.

 

buy rc 550's and be done with it

 

i was tryin to get more knowledge from other people cause this guy i know he bosted 3-4 of his cars and chip himself he said he had no problems wit stock injectors at 8psi just add walbro 255

 

the none of those car make anywhere from 220 - 250 whp anyways tell them to get an fmu while there at it

200%

 

An FMU is not the ONLY way to get more flow out of your stock injectors, ever heard of adjusting the base fuel pressure?

I'm running 8psi boost on stock injectors daily and tracked, no problems, fully tuned very conservative, wideband is active ALL the time, about 85-90% duty cycle which leaves room for adding fuel in for any kind of boost spike that may occur. THE KEY IS TUNING people, and that I can do
