fmu Question

[dbow-4]

what would be a good place to mount a fmu on my 2g nt and my 2 Question is I here alot about some of you guy's talking about a sfmu what is the difference

1. since you are a 95 mount it in the engine bay on the fire wall somewhere.

2. a sfmu is adjustable. with a fmu you get a set ratio(12:1) of fuel pressure to boost. with a sfmu you can adjust idle fuel pressure as well as boost and total fuel pressure.(bleed)

You can get smaller ratio FMU disk ie(6:1, 3:1- FuelSI) But the SFMU is a lot better because it more adjustable.

Check out summitracing.com or Vortech.com, They both should have it, if you don't see it on the website call them.
Also 2gnt.com should have a lil write up about fuel systems. YOur best bet is, to not buy anything until your sure you know exactly what you need to run. I made that mistake and its costly.

A friend if mine gave a vortech fmu I thank it is a 12:1 the reason I am asking is because I am thanking on geting the bottom end kit from concept Illusions Iam trying to get some real hp out of my car like 25 pis when I really want to play I am going to do the bottom end frist and then do the head

wow 25 pis

better start off realistic for now and work your way up to the stars



anywho, when the day comes that you're running 25 pis...you're gonna want a tad more fuel management than a s-fmu. for example: hahn's portfueler has seen some amazing numbers when run upwards of 20PSI, and of course the megasquirt to name a couple

good luck, and continue to soak up the knowledge

Yeah if you want 25psi out of your motor, then your going to have to go with a stand alone fuel managment system, or something like a greddy e-manage at least (which is still a piggy back)
The SFMU isn't the most precise thing in the world.

how much psi Are you running on your 420a and thank's alot for all of the help from you guy's

 

[selmerguy]

ok i will try and explain this.
you can run as much boost as you want as long as you have a built motor and the fuel system to match. a fmu is only good to about 9 or 10 psi. thats it. a sfmu and 440cc or so injectors can do 15 or 20 i think.(might be wrong about the psi for the sfmu)

[selmerguy]

i got a used sfmu off ebay a few months ago and i plan to get a wideband and 440cc injectors soon. i will let you know how this turns out. i think that chick crazyclipse has a similar setup.
