Hey bro just wanted to ask you some questions about my setup. As you know i am making some improvements to my current combo, and think i am in the need of some bigger injectors. I will be looking to make about 430- 440 rwhp. Would 42lbs be too much? Or 36, 38???
Thanks
Mike

Your using an autologic chip correct? If so then you can't really go too big as your tuner can just cut the PW down. 36's or 42's should be fine, stay away from the 38's as they are made by Lucas and do not have the best reputation.

According to Racesystems calculators 30lbers are good for 432HP at 90% cycle duty @40psi.

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

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.

ya thats exactly what i was thinking, the 42's might be a tad to much, but thats what the dyno tune is for.

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 [ October 01, 2002, 10:47 PM: Message edited by: st5150 ]

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.

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?

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

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.
