Does anyone know of a place to find the stock injector pulse width/duration? I can't seem to find it on webtech, hyundai performance, or here. I think the search is messed up here btw.

Anyway, any help would be great.

 

The injector pulse width/duration is how long the injector has to open to supply your cars fuel needs, it has nothing to do with the injector itself, it is just a measurment of the injectors open time and it will be differant depending on your cars needs in a given situation, so there really is no answer for your qusetion.

 

Yeah, good point. I need to know the maximum duration though. It was late when I posted, now reading this I forgot I even started this thing.

Anyway, basically I need to see if I can run 9psi of boost on a 14b on the stock injectors. If not I'll have to lower the boost but I really want to start there.

Anyplace you know where to look?? I've seached HP.com and couldn't find too much, basically the same that is on here.

 

On a 14B you should be fine as long as you don't push the car too hard everywhere you go. 14Bs are small... if you are going to run a 14b make sure your running high octane gas and an intercooler, they create lots of heat.

 

Wow, this thread is a mess, I'm an idiot :hitwithro

I was really looking to see the cc/min for the stock injectors which I found on HP.com I needed to know if I could run the stock injectors to my goal.

By the way so that it is stated on this site.

The stock Tiburon injectors are 245cc/min at 43psi High Impedence.

I guess that is what I was looking for.

Note to self. DO NOT CREATE THREADS LATE AT NIGHT.

 

i've flowbenched 8 of them and they were in the 255-260 cc/min range
a bit more then the 247 cc/min that has been around for a while

 

In that case... try 15psi boost

just kidding rolleyes.gif

 

Really? That's cool Denisst, thanks man.

 

Nice. Never knew they could flow so much... almost makes buying 300cc injectors pointless.

 

According to Hyundai they flow 238cc at 43psi, I looked into it and that is what I found, I aslo checked the bosch part number for our injectors and it came up the same 238cc or 22lb/h.
