Is that 432Rwhp or Fwhp? Big difference at this level.

Musta' had a brain fart...it's flywheel.

ya i wasnt sure if that race systems calculator was rwhp or not i had already checked there. Thanks for the info anyways. I am pretty sure it
is flywheel though.

I would go with 42's. You know you will always be going up in power. Do it right this time or in 6 months you will be buying new ones. Good luck with your combo. Too much fuel is never a bad thing, especially when youadd a power adder

Posted by Camara90 (Member # 134) on :
 
ya thats exactly what i was thinking, the 42's might be a tad to much, but thats what the dyno tune is for.

Plus I KNOW you're going to spray that thing!

I would go with the 42s if it were up to me.

camara you going for those numbers on pump gas all motor?

No nitrous?

I like to use 80% duty cycle for a nice safe number.... so at 80%, you're good for an extremely safe 460 rwhp all motor with 42 lbs injectors at 40 psi. If you want to keep those 36's, you'll need to pump about 55 psi of fuel pressure through them to get them to flow the same as 42's. Your chip will have to be reburned for part throttle / closed loop operation if you're going to go that path. Both are viable options....unless you plan to spray

ya getting it re tuned is no big deal at all!! I do plan on making those numbers all motor without the jug! If I plan on juicing it, it would be a small shot, but most likely it will stay al N/A. The N/A side just seems to gain more respect, even if you loose and put up a good race if your N/A, people are like that shit aint no joke!!

well that really depends on wet or dry, wet it doesn't matter, it relys on his fuel pump, dry it relys on his fuel pump and injectors.

around 400 flywheel HP, with a 150 shot of nitrous on top , you are basically beyond the stock fuel rails capacity and probably whatever intank pump (255lph) you can stuff in there.
 

---

Posted by Camara90 (Member # 134) on :
 
what will the stock fuel rails hold up to rwhp, im most likely going to leave this thing all N/A.

If i need new fuel rails are those aeromotive kits for like 150 able to go right in to the other stuff, also do i need an aeromotive fuel pressure regulator?
 

---

Posted by st5150 (Member # 51) on :
 
Camara90- you can spike up the fuel pressure on some 36's a bit and get away with it, but 42's will definately give you room to grow, its your call. Like JeffS said, stay away from the Lucas brand injectors. Stick with the Ford/Bosch ones. NA, you'll be fine with the stock fuel rails.

nickn- Yeah, I assumed dry... I'm a fan of the dry kit over the wet

Pst....Sawson, Mike's running 30's currently.

Stock fuel rails are normally good for ~500RW. 94-95 mustangs came with rails that flow a little more than the foxes.
The limits of the stock fuel system & the limits of the stock block are pretty close....I'm more concerned with cracking a block then fuel rails.

Camara your car is pretty damn nice! I saw that vid of you vs.( I think you guys call him whytlie. ) and that was one of the best races I have seen. I just orderd some stuff and should have around 310rwhp. what kinda times do u think u could put down in my car? Since there is lots to do with driving I was wondering what it would be capable of. 93 lx aod with 3.73s and bfg comp ta tires

What is part closed loop operation. the way i understand the eec system. the system operates in open loop and closed loop. but what the heck do i know

sskiller, it is hard to know what kind of times a car could run without having some important facts like weight, and gear. What is the current combo? With 310 and a car at about 3450 like mine with me in it, id say some low to mid 12's could be possible. This would be with a descnet 60 foot time in the low 1.7-1.8 range.

Thanks for the reply. I'm gonna have a good friend of mine run the car next summer for me cause our track dosen't allow anyone under 18 to drive.

Mike:
Your stock rails will hold up to a max of 500 RWHP
at the very most.
Thats only W/ a big boy pump though.

Now 36's will be good up to 430-440 rwhp and no more. I know from personal findings. So there for I have set of them for sale only 2K miles on them.

What is your exact current fuel system?? Lines, filter, pump, ect??

the current fuel system is 30lb inj, 255 in tank, stock fuel rails plus lines. I think i will keep the stock fuel rails and jump to 42lb injectors.

What kind of problems were you running in to?

Actually I'm running stock lines and rails, fuel pressure fell off @5500 rpm. That still dynoed more than that at the wheel

Posted by Camara90 (Member # 134) on :
 
ya im looking to push this thing to about 440rwhp, and about 6,800 rpm shift points.

I do want to make sure that these stock rails hold up, and if not can I just buy the rails that bolt right up the lines?

GR40lx: Of coures you could see more power that I listed but what I listed was safe power where your "fuel does not drop off".

YOU NEVER WANT YOU FUEL TO DROP OFF!!

Mike your pump and lines should all be just fine.
Your rails will be fine too as long as you use those 42lb injectors your set up is sound Bro

However if your looking to get a set of 1/2" rails, Aeromotive makes a real nice bolt on rail.
Dude if you buy just the bare rail W/ no lines a nd fittings then I could hook you up W/ all the special fittings a and lines they sell to make it hook up directly to your factory lines.

I bought the Aeromotive kit that is a direct bolt on to the body lines W/ all the correct special fittings and lines, to find out that I could not use any of it excep just the bare rails.
Lemme know Ill hook you up

anyone know if there's legitimacy to the '94/'95 rails handling more fuel? I was going to sell them, but I'll keep the '94 cobra rails if they hold more fuel than the '86-'93 HO?

I think its the line that connects the two rails that is the restriction and changed on the SN95's. the SN95's also have a larger feed tube from the fuel pump, but it won't fit your fox's connector unless you install a larger one as well. Found this out the hard way

66 i think i will stick with the stock rails for the moment, but thanks anyways. Did you ever get a hold of brian at high tech?
