so u htink i could flow enough fuel for this with just a adj fpr and some 550's w/vafc? would i need an fmu or anything like that, or just the fpr? also, i saw a thread on here a few days ago, wher eit said that you could connect some kind of line to the vafc and drill a very small hole in it so that the map would see atmospheric pressure and this would allow u to cut or add any amount of fuel u wanted using the vafc, no matter the size of the injectors, you cut lean out as much as you needed. i'll try to find it in a little while, gotta go do some more homework right now, but when i find it i will post if for u all.

 

rudelude:::I dont even think you would need 550s for your setup if you used an adj. regulator like I am doing now....You also do not need to do that drill mod because you will be taking out so much fuel w/ the afc that it will alter the map voltage so much you will not throw any codes ...If I were you I would get a btm if you have not allready and would not run anymore than 13 psi on pump gas...Oh, and as for the fmu, you should throw it in the garbage or use it as a paperweight because thats about all that thing is good for...Lets keep it simple....afc,440s, and adj regulator, and you are good for at least 15 psi...

ok, with the vafc would i ba albe to control a set of 550's? i see what ur sayin about not relaly needing them, but u do remember this is a h22a (fuel hog) and i really wouldnt wanna run extremely high fuel pressure with the 440's, and i may want more after i play with the 15psi, so thats why i was skin about the 550's. but would the vafc be albe to control them and have good drivability and good idle? i could get a set of dms450's for alot cheaper than the 550's, but i would rather have more than enough fuel than not enough, know what i mean? so if the vafc could control 550's, i would lean more towards them.
thanks for all the help too by the way.

The question is not so much whether the AFC Can control the 550s or not as it doesn't know what sized your injectors are using. There is no settings as to what sized injectors you are using on the AFC. All it does is adding and trimming fuel. You can't generalize and say if someone has run 15psi on their setup it will also run on yours without CEL. It depends on the combination of parts, ie turbo sizing, injector sizing, type of motor, fuel pressure etc....and only trying it out yourself you will know if it will work or not unless you have an identical setup that someone has already done and know works.

To answer your question I think you'll be better off with 550s are you have a H22 just so you have more room to play with as with the AFC you can trim up to 50%.

What size are the stk H22 injectors?

 

I would put my .02 in, but "swlabhot" summed it up just about perfect.....The main thing you have to ask yourself is....Do I have big enough ***** to risk ******* up my motor????????And with a h22 runnin that much boost, I would hope it was sleeved......See, my motor on the other hand has an *** load of miles on it,and I kind of expect it to let loose in the near future, but then again I said that 7 months and about 80 dragstrip passes ago....Just goes to show you how importiant a wideband really is.....

 

dude, I would not run any higher than 13 psi on a stock lude motor. I heard the sleeves can't hold ****.

I would seriously just go with 440cc's, aem fpr and run the hack at 10-13 psi.

 

yeah, my buddy blew up a couple of the old h22s.....well keep the name quiet though...

 

i'm runnin rods and piustons, and the deck is closed so i think itll be ok for 15psi, i know a few people running this setup, and its runnin fine for well over a year

 

RUDELUDE:: The deck is closed????Meaning blockgaurd or sleeved????

i have the h22a, which is found in the 4gen vtecs, and is closed deck. the h22a4 is whats in the 5gen vtecs, and this motor is a open deck. with the h22a, the only thin g u can do to strengthen the block is sleeve it, i cant use a block guard cuz its solid.

 

99lspwr:: question about igintion timing with ur setup. if using the stock ignition and timing, the stock compjuter would advance thetiming in the same places as if was running N/A correct? thats why there are problems with ignition over certain psi levels because it causes detonation due to too much advanced timing for the boost level right? if i was to leave my stock ignition and timing, and use a water injection system for above say 11 or 12psi, i could benefit from the extra power made from the more advanced timing instead of retarding it and losing power from that right? the thing is, i plan on using a water injection system anyway, so with this i wouldnt really have to retard the timing or anything, so would i be able to make more power like that?

 

I would retard the timing a little...Running full advance is not a good idea w/ 11-12 psi of boost...Why dont u put a msd btm on your car....that way u could pull timing under boost to be a bit more safe..

No offense but the last thing on my mind when boosting a stock h22 is the sleeves...the ringlands on the stock pistons shear if you look at them wrong. On a stock bottom I wouldn't go anything over 10psi and that's if I was feeling saucy.

hey clendaniel......What do u know??? ....j/k fool...
