Turbocharged question!!!!!!
since it looks like you have some AFRs....it looks like you will be flowing some pretty good air. your turbo selection will also have a lot of input for this answer
it will be close to say it vaguely.
just having an inline pump and 60# injectors wont give you dick. youre going to need dual intanks or a biggg sumped inline setup with some -8an feed and a return with a regulator. with a boost referenced regulator, cranked fuel psi will help you a bit....but you really need th full system.
~850rwhp should be doable with 60# considering the rest of the setup is gude.

If you have an upgraded in-tank fuel pump like a walbro 255-340 and a hot wire kit to the fuel pump to keep up the voltage and a Progressive Methanol Injection Kit you should be fine! The methanol injection will lower your injector duty cycle quite a bit plus alow you to run some more boost if you want. I personally have a log of the duty cycle, here is the results:
Without Meth inj: = 84.7%
WITH meth inj: = 70.2%

I'm running 85lb injectors with dual in-tank pumps on my 86' GN and one of my Progressive Meth kits and I had boost up to 27lbs on 93 pump gas with No detonation at all. The turbo size is a 70mm by Precision. I still get 22mpg! I was going to go with the external pump but I decided to stand back and decide what it was that I really wanted to due and I went with the dual in-tank pumps instead. VERY HAPPY!

I kinda thought that boost was irrelavant. The amount of fuel needed is based on the hp you will be making! I have 60# injector's on my setup with 2- bosch 044 pump's and made almost 1100rwhp last night.I am sure they are set on "supersoaker"mode as of now,but if tuned properly with enough pressure you will be fine!

so if i run the 68# injectors and the aeromotive eliminator inline fuel pump will be ok with a -8an pickup and return lines with a good regulator setup i sould be ok with that fool system. or do i need to run a meth kit also to be on the safe side.

I would run a -10 fuel feed line and use your factory feed line as a return. Get a FPR also. Methanol is good to use also fi you like. I personally don't use it.seen to many thing's go wrong and hurt engine's.
True. But a N/A car would need the same amount of fuel if the hp goal is the same!That is all I was saying. It is HP goal related,Not necessarily boost related.You need a certain amount of fuel to reach your HP goal's,whether it be boosted or N/A.
You are ignoring the fact that boost affects the pressure differential between the injectors and manifold. Higher boost means less fuel flow on a returnless system. On a referenced return system it means the fuel pump has to work much harder. On the other hand, N/A motors tend to spin to higher rpms, which cuts available injector pulse time, hence the reason generic injector size calculators tend to be fairly "close" for most motors.

hunter what was your duty cycle??? (congrats on some awesome numbers) I was at 105% duty cycle with 75lbs right at 900 rwhp and we switched to 96lbs and now I'm at 80%...just a thought but I would put the big boys in there so you don't have to buy 2 sets of injectors like I did....
