Injectors for HKS t51r SPL BB

Iv been doing more research on the Walbro 400lph as I'm wanting to turn up to 550rwhp.
I've found that the pump makes 400lph at 40psi at 12v, but begins to trail quite significantly in output as the pressure increases.
At 80psi the pump only provides around 225lph. If you are trying to run 500rwhp you need around 250LPH at 80-85 psi if you are running around 20-25psi of boost and you factor in a 15psi pressure drop by the fuel lines that must be overcome by the pump.
So it seems that 2 pumps may be needed to go beyond 500rwhp. Seems like ID's or not, the OP will def need two pumps to reach his desired output.
What do you guys think?

On a mustang dyno made 565@23psi.....I did run out of fuel as inj duty was beyond 80%.
Also anything over 18psi...OP will need e85, race gas or meth/water injection

street port
MSD Ignition on leading only
B10EGV's on both Leading and trailing
Magnacore 10mm wires
TII - Leading Coil
Fuel as stated above
90mm resonated midpipe with 90mm exhaust
stock tranny
TII lsd
anything else you want to know.....just ask......i keep no secrets

I do have more. Lol
What injectors are you running? ID's or bosch.
If Bosch, are you running resistors or an injector driver?
What ECU?
What size street port?
You said you ran out of fuel/injector duty %80...did you monitor fuel pressure to see if it tapered off?
I'm a assuming you have the hks kit...what wastegate solenoid are you running and how is it setup?

850's are stock - no resistors
PowerFC
Street port
i dont like to run inj above 90%. on the dyno we were getting close to 90%. Dialed it back to less than 80% for street. Did not run out of pressure. pressure was fine with single Bosch 044.
HKS Wastegate. Everything is HKS, mani, turbo and wastegate.
here is a vid of one of the final pulls

thanks for the info, papsmagu.
What SIZE street port is it (med, large, monster,etc)?
When do you start seeing boost?
What I was asking before was about how you wired/plumbed the wastegate control solenoid...assuming you have an aftermarket one.
As for your fuel injectors if you ever want more fuel you could install an injector driver.
Howard Coleman reported dropping 15% when he installed his FJO inj drive.

Have you considered Water/Meth injection?

Large Street port. here are some pics
Start seeing boost at about 3800 rpm
Im a bit lost about wastegate control solenoid. If you are asking me about my boost controller, it’s a greddy profecB Spec 2, installed per greddy diagram?
I have seen the FJO inj driver and personally thinks its old technology. I know some people that run it with great success. If I need more power, I will upgrade to ID 1000’s and 2000’s

Thanks op. And thanks magu for the info and photos. I'm just now starting on building a base cal/map for my SPL with an aem series 1 ems.
Any chance I could you could email me your, I'm guessing PFC, cal/map so I can check it out, learn, and convert it to help me build my fuel and ignition tables?

Hey mate. This might sound like a bit of newb question. In your video, what was the "cling sound" I hear in the background. Was doing it every time you changed gears. Clutch ?

That's my blowoff valve you hear when the gears are changed.
Send me your e-mail and I will send you my map. Not sure how your computer works but pfc has base map for fuel. Correction map for fuel. Leading and trailing maps for ignition. One thing that you have to careful of I'd that the pfc has about 5 pages of correction factors built in....so what you see on the ing and fuel maps may not be the numbers the pfc is using. Anyways I'm sure you know this already and are simply trying to get a good starting point.
Are u using REw or RE? Make a huge difference. My last motor was an REW w the same set up so of you need I can send you this map in lieu of the RE? Either way let me know

Thanks heaps for your help there. This will help heaps.
13B REW is me. Email: jase03@yahoo.com
Greatly Appreciate it.

Im running a large street ported REW that I port matched to my upper and lower RE intake manifolds with a 90mm throttle.
If you could send me both maps/cal I'm more interested in studying them. I'll pm you my email. Thanks!
Jas,
Just a heads up. Don't expect to use someone else's map. Its more of a starting point as not all engines are the same. Be careful.

Map sent to individuals who requested. It's for REW not for RE. I found you need to add about 20-30% more fuel with RE. I will have to download my map from my car to send you the RE...that may take a bit cause I'm lazy. But the map I sent will get u going in the right direction

Nope, REW port matched to RE LIM..plates are pictured above
because that is how much fuel i had to add to my map to get the car to run properly.
now please save yourself some time and not post the difference in port size btwn an REW and the RE and why you would have to theoretically have to add “X” amount of fuel per CFM because I really don’t care. I am trying to help out the two individuals who have asked for my help. I am giving insight on what I did and what works for me…..i am not telling them what to do based on something I read in a magazine or on a forum…again, I am telling them what I have done and what has worked for me.

It's possible that the vast difference you saw between two extremely similar blocks was due to differences in your two setups. With that in mind, it's probably not a good idea to dole that info out as a rule of thumb.
Were they stock blocks? Ported? Manifolds different, or using an RE manifold on an REW block, or something similar?
Your experience and opinion are a lot more valuable when you're willing to discuss and explain them without getting all butthurt

I didn't assault you, I asked you a question. If you don't know the answer, that's fine. But, after that response I hope everyone is taking your advice with a grain of salt.

My previous set up was a relatively stock REW. New set up is REW port matched to RE LIM with a large street port. Also housings were ported.
Any other questions feel free to ask...as long as its phrased properly I won't get butthurt ahhahahahahahahhaha

Bigger ports flow more air.
The added air flow requires more fuel.
RE intake ports are 20-30 larger than REW intake ports.
So what your saying is that if I do a Bridge or P port to my engine it won't require more fuel?
