Would 550cc injectors be sufficient enough for 11 psi with the following upgraded fuel compnents using a To4e turbo?

Walbro 255lph Fuel Pump
Custom Return System
+Adjustable Fuel Regulator
+Ptuning FPR Plug
+OEM Tapped Rail

I know this would be enough for regular pump gas but would it be enough for e85?

 

you might be a lil short or high duty cycle.. im sure 700cc will do it. my 900cc goes to about 60ish% around 11-12psi, base pressure around 50-55psi

 

Thanks-Im hoping to use the 550cc and boost the base pressure up if I have to but I dont want to exceed 60psi base fpr - Any idea how much power it would make - 11psi-e85-t04e???

 

ohhhh yea its a 50 trim

 

Interesting... Curious myself as to how much it would make. Is a return fuel system a must for E85 or does it just make it more reliable?

 

Well not a MUST but deff better than returnless...with e85 you will need 30-40% more fuel compared to if you were using pump gas from what I understand. So the return fuel will help by getting the most out of your injectors.

 

lets just say its a little of a must will let you get the full use of it a little better

 

I run 16 psi on 60-1 on E85 using 700cc injectors Im at 78-82% idc depending on weather. Oh but I run 70 psi base fuel press haha - my rail pressure under full boost is like 86-87 psi haha

 

Thats pretty good thought gotta love the return system. The 60-1 turbo is bigger than the To4e though right? Im not too great with the sizing of different turbos but am trying to learn

 

550cc will be fien for like ~300 hp on e85 with all ur supporting fuel mods

 

Yea 60-1 is quite a bit bigger. Im also on 9:1 compression though. Im probably gunna pick up some 1100cc injectors from ptuning when i get paid, and a second walboro, and the stuff to make a 3/8" feed line Than I should be good for over 500 on e :D Ill prob have my 700cc inj up for sale in the classifieds soon

 

I am pretty sure the 550's will hold more than 300 along with the walbro 255 and the return system

 

Depends how high you turn the fuel pressure up :D

 

pushing that limit if u run e85

 

ya lol 550's with walbro max out depending on tune 10-14 psi.. and ur trying to push that psi with e85? yikes

 

No I bought 700cc

 

What fuel pump(s) are you running?

 

Single walbro 255 at the moment. I looked at the flow charts for them, it looks like Im pushing it to the max right now haha, im gunna be looking at going with twin walbro's or a bigger inline pump when i put the bigger injectors in this weekend.
