Fuel pump for 600hp?

[ss dave]

What pump would be appropriate for an in-tank set-up for a 600hp LS7.
Would a pump rated at 255lph work? Thanks

More info if you need it, it will be a NA engine. Most likely with 42# injectors.

42 sounds on the small side, you will have to run higher fuelpressure to fuel 600 horses with 42 lbs injectors, that or dangerously long duty cycle, also if its high impedance injectors your you will limit your dutycycle at high revs as the minimum injector turn on time is unchanged,

but a 255 lbs pump should just cut it... personally it run two and turn the other on at wot over a set rpm..

but do the injector math for what ever injector you buy, they are all different

thanks, I'll check into the injectors more thoroughly. As far as the pump question, I'm trying to keep it simple and reliable, so wouldn't an Aeromotive A1000 or similar work better for an in-tank application?

i have seen an A1000 mounted in tank.. so it is possible.. i just think its a little noisy, and it will heat the fuel more than a smaller pump, it draws somthing like 30 amps, all of which turns into heat in your fuel eventually.. you could contact kinsler and have a chat with them about your pump and injector needs.. but an A1000 will certainly deliver enough fuel

Thanks Deuce, I did have an external Holley for the 383 so I know noise, but with Flowmaster 50s it didn't last long. But your advice is appreciated-thanks.
I don't know about Copenhagen but Kansas just had a nice little 8" snow dump. Looks so Alpine!
