Just upgraded from a old gt30 running 22psi stock engine 99oct shell optimax.
1000id rewired 340 full blown pump, with added boost a pump giving a constant 14 volts (can give 17 volts ).
Questions what psi will I run out of fuel.
Also probably limited by my act HD with there street disc.
Any dyno graphs advice cheers.

 

you'll run out a fuel when you max the pump or injector? lol

Confused to your question.

1000s should support 550-600 on gas Pump on the other hand im not sure what the 320s will support on gas.

Of course flow mods, and fuel psi will determine alot too.

 

Just wondering what boost levels that will be so I can put the correct wastgate spring in before it's tuned cheers.

 

What DC are your injectors on now?
Maybe upgrade to a walbro 450

 

it really depends on what fuel you will be running. With gas meaning not e85 like standard pump 91/93 octane or race gas like 100 octane or c16/q16. 1000cc injectors will support about 600whp and a 340 pump will support more than 1000cc will. But if your running standard 91/93 octane you will be octane limited in power. Meaning you will make somewhere in the 400-500whp range. Also this day and age no one really runs race gas anymore. Most people looking for more power than what pump gas can support normally run e85. e85 uses 30% more fuel. So 1000cc injectors only support about 450-500whp. So your injectors are your weakest link. Also your act clutch only supports about 500whp max.

Here is my old dyno with my stock f20c with a gen 1 garrett gtx3576r. With proper supporting mods and fuel a gen 1 gtx3582r can easiely support over 700whp

 

Good information thank you
