You have to deal with maximum pressure abilities of the system, which varies with your HP/fuel consumption. Typically systems operate up to 75psi, but this is only if there is sufficient pumping capacity to maintain this pressure.
On a G8, I start at 58 & boost reference to the pressure side of the inlet tubing. You cannot reference to the intake as engine vacuum lowers the idle pressure & will cause the transfer to stop functioning.
Typically, I recommend a large injector & running a fixed 58psi with no boost reference in these applications. This is the easiest approach as long as you calculate the injector size properly.

Your pumps
-8 feed line to Aeromotive 12335 Fuel Filter
-8 to Y-block then -8 to rails
-8 from rails to Aeromotive 13101 Regulator A1000
-6 return
HP expected to be around 550-600, injectors are FAST 65#, car is drag race only.
see any glaring issues?
thanks Lonnie!

Why would you want to run the car at 90 psi of fuel pressure anyway... from all the flow data that's been presented here, it would seem to me that running between 45 to 60 would be rmoe then adequate, unless you're trying to make up for a lack of injector flow with added pressure (which means you need a bigger injector)
If' I'm missing something please fill me in.

I am sure that once these things get out there, that the fuelie guys, as well as quite a few of the big names, will have more info. I think we would like to get a few in here to see what they will do. If I get any in, I will keep this thread updated.

Hell we've done cars with the base pressure in 40 lb range... they run fine.

I'm sure it can be.... but it may not be designed for the application.
What you need to be sure of is that you get a pump with the factory style venturi design so it works properly. I'm not sure this will be an option with this pump. If so great...
The issue that most are missing here is if you do not need a pump this big, why worry about it. Remember pumps do not make ANY horse power, they only support what the engine is capable of. Your 550bhp is not an issue with any good 255 pump.
For reference, the stock pump in an LS1 f-body will typically support 500 crank HP. I've seen many stock ProCharged cars (which are rated at 540 crank) with a stock pump. But I've also seen many need a pump upgrade.
I'm still waiting to get my hands on one of these new 340's to test it out & see if they live up to all the hype.

I'll leave it alone until I need the bigger pump. Thank you..

I run N/A cars at 58 & on forced induction I try to work backwards from the max boost referenced pressure to determine my base pressure. I typically try to design for a max of 65psi at peak boost if possible. This means a car with 20# boost would start at 43.5 base pressure. On cars with very high boost we have lowered base pressure even further with good results.

If you have a GTO, I want your GTO bucket not an 8.1 bucket for dual pumps... You can sell the 8.1 to someone else.
If you want more than the duals can provide, I can also do a triple pump for the GTO as well. Give me a call if you want to disccuss the build in more detail.
