what fuel injectors do you guys recommend for an f1a pro charger. ill be getting one soon and would like to go ahead and get my injectors. looking for 700+ rwhp engine is a 355 fully forged with diamond boost pistons. cc503 cam le2 heads stock intake and throttle body for now. and will a walbro 255 fuel pump be enough or will I need a dual setup thanks.

Minimum of 80lb sticks and they may be maxed on stock lines, rails depending how far past 700rwhp you are going.

i did not even know fuel lines and rails had a hp limit but i guess it makes since. i was thinking about running about 700 hp on the street. i probably wont start at 700 but boost is addictive i know ill want turn up the boost eventually. and maybe using a 150 shot on the track that should bring me close to 1000 hp. i would rather buy stuff once than to buy something then find out i need bigger injectors and have to re buy them what is the limits of an f1a on pump gas.

-8 AN feed, -6 AN return lines with rails modded to accept should do the job. You should also look into bigger pumps as well if you want a do it once approach.

what pump would you suggest

Racetronix has a twin 340 kit. The twin 255s are said to be able to handle 1000hp with sufficient fuel line size but I'd recommend a little head room.

for some reason there online store is not working at the moment but I did find this complete kit includes lines and the double fuel pump kit kind of expensive at 1800$ but I've already sunk a small fortune in to this car so what is another 1800$ lol

If you are looking for plug and play, this would be the way to go. You can always piece this together yourself but there is the appeal of having it all figured out and done for you.

I have the Lonnies double pumper kit minus the lines/rails but I plan on upgrading perhaps next season. I sourced a nice set of modified rails/regulator so I just need to make the lines.

thanks for all the help I looked at your build and I thought I had some good stuff yours is better lol. I hope what I got is good enough for at least 700hp. the only thing I am real worried about is I forgot all about my mains and left them a 2 bolt. when I sent my block to the machine shop this is my first build so I guess ill have to remember that the next time I build something you live you learn. I am far enough along now I am thinking about doing a build thread.

No problem. Looking forward to the build thread. Good luck.

The stock lines are fine, the problem lies within the rail. Plumb them in parallel with twin 255s.

I running 96's w/ twin 255's no problem modified rails, -8 feed in parallel and -6 return What size pullies are you going to run, 8 or 12 rib? May be selling my 12 rib system w/ new unused belt and SDCE bracket in the coming months. 3.85 blower and 7.65 crank.

I was wanting a 12 rib system less belt slippage I hear

If you are sticking with in tank 255/340lph pumps, go larger on the sticks. Otherwise, use the 80# sticks and a larger fuel pump capable of holding flow at high pressure.

Fancy injectors

dam 1800$ for injectors crazy lol would 96# injectors work or do I need larger if I were to stay with the 255/340lph pumps

If you can find decently priced high impedance 96# sticks get em. the 255/340 pumps do not like to be asked to flow well at high pressures, which with a 42psi base and say 15psi of boost is gonna be a lot to ask of em. IMO.

Def go 12 rib and make sure the pulleys are aligned as perfectly as possible.

They are "fine" but not ideal based on my experience. While I'm decently above 700rwhp, I seem to be close to the edge of stock lines and rails.

This.

I've heard the same thing of 255's not liking high pressures...but I've never ran into an issue however I know I can be the exception to the rule of course. INTIMID8 ran twin 255's on that infamous 355ci TT into 800rwhp+

They are low impedance, means you would need a injector driver to run em.
