Going with a pt88 turbo starting to part everything together. what size injectors for at least 13lbs of boost.

Injector combo with rails and what fuel pump/pumps are yall running, was looking at goin with a double or triple walbro setup similar to mity mouse.

 

More information is needed before ant reasonable suggestion can be made. What size engine, cam, heads, etc.

 

need all the info on the engine.. Or better yet if pro built ask the builder what this will make in CHP, then I can calculate the size needed. Also what fuel?

 

i was running some 42's on 12psi at about 80% duty cycle i think i was about 60-65psi worth of fuel pressure.
now have 96's so i can run more boost.
engine is a 347 and of coarse the PTE88.
dual intake walbros when the second one would come on at 5psi
8an feed, boost regulated FPR (i think the base pressure was around 50psi)

 

I run the 80's in mine. Not enough for corn fuel.

 

itll be a built 347 or nothing bigger than a 408, 317 heads running a max of 950rwhp with around 15lbs, cam is undecided as well.

 

id get at least 96's

 

I was maxing out 50's on 14psi (some stupid 1XX% DC), 65's on 17psi, and my 95lbers were pushing it at 85% duty cycle at 19.5 psi. Go big low impedance injectors with a driver or ID1000's and get it done right once. I'd probably just do the ID1000's.

 

Exactly...get the biggest you can. You can never have too much fuel system.

 

what do i neeed for pumps?

 

2 walbro 255s should do fine but your limiting factor will be feed and return lines next.

 

what size feed line and what size line for return?

 

you really need to look this up in the fueling section... that or just pony up and buy a lonni kit that has everything already figured out for you..... Nastynate i belive is a retailer too

 

Id say -8 braided stainless feed fuel line, and -6 braided return fuel line. Just to be on the safe side.

 

Do they sell a bigger injector for a stock PCM? I have a LQ4 that i plan to add a 78mm turbo to, but i plan to use Alky to help with the fuel. It's a 2002(PCM). What size inject do i have now, how can i tell?

 

88mm on a 347 tells me that 83lb injectors would work with a decent amount of fuel pressure. Otherwise you could use 96lb injectors with a driver box if you wanted to run lower fuel pressure.

 

thanks
