ok i finally got my car runnung so good i am scared to dip in full throttle in 1st and 2nd gear. hoping to go to the dyno and see how much i picked up this time. it was 205 on a dynojet. i would not be surprized to see it hit 240.

anyway i am running 39 psi on fuel 440cc injectors (peak and hold) skunk2 stage 2 cams, header-tech header, p&p head, over sized valves, 13:1 compression. AEM ems

my duty cycle is about 65-75%in vtec wot. actually it is mostly 75% what do you fella's think about that?

 

Why dun yu turn the fuel pressure up?

 

yea i h ave anothe rpost regarding this problem it is the 2nd regulator from twm, it wont go any higher. i need to send it back to them, gary is going to check it out. i need to check it first with another guage first. i wonder how much it with change the duty cycle. i was really surprised to it go that high. i am over 10 ms of pulse width.

 

what your a/f ratio @ 75% duty on the dyno ?

didn;t understand how you got from 205whp to 240whp ? did you tune it yet ?

greg

 

no tuning yet, just pulls a hell of alot harder. air fuel at 12:1 on my aem ugo. i am gretting really bad gas mileage too. like 10mpg. i luv it.

 

how do you know how much it will make then?

 

i dont klnow exactly, just guessing. i said "i wouldnt be surprised if it hit 240." i didnt say it will be 240. calm down.

 

i'd want to size my injector to be at 80% duty cycle and with stock fuel pressure...but thats just me. So, i think you're good at 75% @ 39 PSI.

 

anyone else back that up? i thought 50% is where you want to be.
