i just bought an ported fp-red and some other stuff along with 880cc injectors now i'm thinking i should have went with 1000cc?

i dont think ill run any other gas besides pump 93oct for a while but just in case i want to run c16 or meth ill need the 1000cc's rite?

so what does the 880's max out at- whp/boost?

 

You should be fine im runnin a 61mm and put just over 400 on mustang dyno and injectors are at 78% with 880s

 

Might help.

880s on gasoline will run out around the low 500whp mark, but can probably be pushed to 540 before they went static. I wouldnt advise that at all though, but on the Green you'll be okay.

 

can i run 880's with meth and 30+psi?

 

Yes, that seems to be really popular around the NW. I have a few 520+whp cars running that setup that have plenty of fuel.

 

just sell 880cc and get the size you need , if you are planing on running e85 you need something bigger

 

As John said that would be a fine setup.

I used to run 880's on my personal car with a m15 jet on a smc alky kit, with a 35r ran out of injector around 570whp on a mustang but you should be golden on a green

 

heres a pretty good break down of injectors....

End all: "do i need a fuel pump/bigger injectors?" thread

 

thanks for all the good reply's

i'm going to stick with my 880's

oh by the way its not a fp-green its a ported RED

 

If you makes you feel better I was running on 780cc injectors with a FP Red...

 

1000cc ftw might as well get it now while your waiting on stuff and you have the chance to change

 

^^ yes i can change at the moment but just dont know if its really worth it?

if the 880's can supply 500whp, i dont see me needing more then that for my dd

1000cc work good with stock ecu?

thanks guys!

 

Injectors aren't a matter of what hp you want to achieve. It matters the mass airflow that your setup can and will achieve and what AFR you will be running (assuming that your fuel pump can keep up in the first place). It's pretty simple math at that point, though.

 

Here's the math for you, just in case you don't what I am referring to:

880cc/min injectors

4 injectors = 3520 cc/min fuel

specific gravity of gasoline (.73-.76, .74 commonly used)

3520*.74=2605 g/min fuel

2605g/min fuel / 454 = 5.73 lb/min fuel

So, what AFR are you going to run? 11:1? 11.5:1?

At 11:1:
5.73lb/min fuel * 11 = 63 lb/min airflow

FP states the Red is a 60 lb/min compressor. So, yes, 880cc injectors should be able to support a maxed out red on pump gas, assuming that your fuel pump is up to task and the injectors truly flow 880cc/min. But as you can see, it will be close. However, you probably won't be able to max out the red on pump gas anyway. So, you should be OK.

My opinion...get a fuel setup that can handle a maxed out Red on E85. Proper injectors and fuel pump (dual pumps). That way you only have to go through it once and be done with it.
