LS1 Turbo Power guesses
Since no one else said it you may run out of injector with those 60's at 600-650whp.
Every application is different but my 60's ran out at about 580rwhp with twin 255's, CNC ported 317's and a turbo cam.
My fuel system is by no means optimized but file that away in the back of your head if you start running out of fuel lol.

hmmm if a fuel issue comes up ill keep that in mind, id like to think 60's have a little more in them than that. Previously had 36's while it was pushing around 450
Alright, so the fueling did become an issue. HP is at 450, Torque 483 due to my own ignorance of not having a boost referenced fuel regulator. So, best options? aeromotive seems to be a popular choice, but the whole turbo build is becoming more and more of a learning experience. Thinking of installing a meth kit as well, but for now the fuel system is holding the car back

i went with a holley regulator but i also dropped in dual pumps, bigger lines and holley rails, and 95lb injectors. Now i have fuel for days.

pretty sure if you are running low on pump flow, you do not want to increase the diameter of the fuel feed line. In other words, you can make more power with a -6 on a single walbro, than a -8, for example. Bigger lines help flow more fuel- if the pump can support it.
pretty sure he said 60lb injectors. Which are no way done at 450hp. he also said lack of reference to the regulator which means he doesn't actually know if he is out of injector yet. In other words, even if he hit 100% DC @ 450hp, we both know the injector is worth more than that with the proper fuel pressure. Once the fuel pressure is fixed by referencing it, the injector will obviously support more power. The pump is going to run out of flow faster with more pressure in the feed line- is that what you are getting at? If so, the issue still wouldn't be with the injector, which we both already know supports more than 450hp. I just don't see the point of the question. Its not like he can respond with "it ran out of pump" and you could tell him "ok lower the fuel pressure and the pump will flow more fuel", that doesn't make any sense.
okay okay. yes 60s which i know will support what I need at this point, I had 36s when it was NA making 430. The issue was that as boost built up, fuel pressure decreased. So i know that I need the regulator for that issue. But when it comes to overall fuel delivery and the line size, im unsure. Im not sure what the ls2 fuel rails are rated for, but that along with the aem 320 pump, is about the extent of the fuel system mods. Hope this helps!

I found this at least, theres probably other ones

There are lots of ways to look at these. Just get a general feel for what it will do, then be very wary as you approach the limitation on your own vehicle. Looks like it should do something like 600rwhp no sweat, assuming you started with 44psi base pressure (which is where I usually start, or even less sometimes). The base pressure is reduced by engine vacuum when referenced, and lower pressure typically means longer pump life, so I try to use the minimum pressure possible.

Raising fuel pressure makes the injectors flow more but causes the opposite with the pump.

Currently running 11-12 lbs. with a T7875 and I have no delivery issues.
I'd say a regulator is recommended but not required, my setup has been proven to support 700whp which is why I copied it lol.
I don't know what kind of power it makes unfortunately but I'm hoping for at least 600whp.
Shopping around I found nasty performance line kit, that seems to have everything that I need. Now the question is to stick with the aem 320 for now (not planning for crazy high power right now) or hold off and move to a dual pump assembly with a switch at 4lbs.
I would do twin pumps. You can build it yourself. MightyMouse made a thread years ago how to do it. Original pics are gone but he updated in 2011 what a nice guy.
