whats the max hp made with 440cc with the high fuel psi

the afc/fmu setup

i got a 5:1 rise rate

 

your car is going to have a hard time idling with thos injectors

 

AFC should be able to idle the car fine. You should make around 300 hp safely with that injector setup. Any more the duty cylce will go max 100% which is not bad thing but get bigger then have more fun.

 

thats what the s-afc is for i got them in there now running 15psi of boost

and the afc is -30 across the board and idles good

 

my goal is 350whp u think any way i can get it with that setup with on 440cc's

 

You'll need to up the pressure (i.e. FMU) to get that much from 440's I belive..

 

let me see

(350*.6)/(4*.9)

210/3.6 = 58.3

you will need around a 55lb injector to be safley hit that hp

If you stay 300hp you can manage it easily with the 440cc

if you hit around 330-340 you will be at 100% duty cycle at WOT

 

my car made 380whp with 440cc injectors and a walbro gss317 in-tank pump.it made 434whp with an in-line pump.

holy ****, why such a differance? I've got 550's , how much can I safely make with those? which intank should I get , I know whalbro makes several differant ones

Walbro GSS342 will be good for you. I'm assuming the difference in power is because the Walbro doesn't cut it at high pressure. An inline pump will be better for you if you are planning on using an FMU with your setup. How much power are you looking for? You may not need to use an FMU, if that's the case the Walbro will work great.

 

there was that big of a difference just from a inline pump???? holy s#$%!!!!

and i thought you werent supposed to use the FMU wiht the afc hack?!? i pulled mine off.....should i put it back on???
thanks!

 

just the afc not the afc hack

 

did you use two sets of 440's to make 434hp?

 

Wait a minute, (in your sig) you mean to say that in Japan, people do USDM conversions? LOL

 

no, Dee's sig is a joke, he bought a very early SiR-G, and it came with that front end because they didn't have the "jdm" front out yet.

 

so howmuch power can 440's or 450's support, roughly??

 

at one point, i had close to 360 to the wheels on 440's and an afc.

 

I have a Hondata 2B and I'm looking for around 400-450 hp with the boost turned up ( how much boost would it take- B20VTEC w/ Drag gen 3)

 

i had a 12 to 1 fmu and only four injectors.on the walbro the pressure maxed out at about 90psi.with the inline,it was 100+.the gauge would not read any higher.use the walbro.the ramp-up in pressure with the inline is so dramatic that it makes the bottom end suck.

 

 

damn...i want to make 300whp!! dyno time needed...experienced tuner needed!!

 

I make about 370whp, but my 440cc are too smal, switching next week to 720cc.

 

What is your compression? I'm guessing you will need about 15psi to reach that level.

 

9:1

 

I guess I should have asked for your whole setup. It is hard to say without knowing what turbo and trim, etc. I think you could hit those numbers with 20psi though.
