Injector Size Question

So I am upgrading the turbo to an Old School FP Green, and the seller (Member here on EvoM) is including some FIC 680's with the turbo. My goal is right around 350-375whp. My question is.... With the mod list below, would this be feasible?

New Setup:
Old School FP Green
FIC 680cc Injectors
Walbro 255
Stock Block
Stock Head
ETS 1.50" Tubular Manifold
Injen Intake/UICP
ETS LICP
TurboXS FMIC
Muse 3" Exhaust
Muse O2 Dump
Test Pipe
TurboXS MBC
Dyno Tune (Granite State Dyno)

Previous Setup:
Muse 3" Exhaust
Test Pipe
Injen Intake/UICP
ETS LICP
TurboXS MBC
Walbro 255
Stock O2
Stock Injectors
Stock 8 Turbo
Stock Block
Stock Head
Tuned @ Granite State Dyno (274hp/258tq)

When it was tuned before, it was a very conservative tune on a very tired stock evo 8 turbo.

My biggest worry is the injectors will be at a high duty cycle, causing the pump to work a little bit harder than it's supposed to. Worst comes to worst, I can go with 1050's but I'd rather save the money for now

This is the tuning and results forum. I'm asking about tuning and whether or not I'll make a certain amount of power off of a setup.

If the mods don't like it, they can move it.

The real question is what is your end goal? How much do you want to stress the equipment? Is this for 93, or e85? For me with a whp goal of 350-375 680's don't offer you a lot of head room. If you're not wanting to through down coin on the 1050's, 950's or 850's are cheaper and will give you some head room.

680 will work fine for your old school green on 93 octane, but will not leave any head room for the following upgrades.

as for fuel pump.. its not about your injector duty cycle, but about amount of fuel needed. 95% of 680cc or 65% of 1000cc doesnt matter, that will be about the same amount of fuel per minute.

It will be on 93 octane. We don't have E85 up here (Too cold in the winter)

My ultimate goal for now is 350-375whp until I get the block and head built. I know the FP Green is capable of alot more, but I won't be pushing it past 400 without motor work done to it.

The fuel pump should be fine, I think. IIRC, people are making more than 500+ on a single Walbro.

Thanks for the input guys.

Please follow the rules before posting. This is not a section to ask about tuning - it is for posting dyno tuning results.

First of all, I didn't mean to start a post in the tuning results forum, I thought I was in the "Engine Management/ECU Tuning" forum. Second of all, if the moderators don't like where this is posted, they are more than welcome to move it. And last but not least... Do you post stupid **** on people's threads to get that many posts? Or do you actually contribute to this community?

epic facepalm on this section today.

Either that, or the Mod took a day off and we get to see what it's like with no moderation.

Are you running an FP Green?
Nope, stock 8 turbo.

With the green you should easily pass 350

Yeah, it's a shame to see someone make a mistake by posting in the wrong section. He should be banned, huh?

Stock injectors? Or upgraded?

I made ~350 whp with a OG green on a low reading Mustang Dyno on 100 oct gas. I was using 750 RC injectors at the time. You should be OK. I would try using your 680's first.

Thanks for the input. I'll give the 680's a try first
