i'm shooting for 500whp, and i've got sieman deka 900cc injectors waiting to go in.

queez

yeah. i guesll i'll be going 850cc.. i can get a good deal on them.

GRTechnologies

a 720cc inj should be fine but the biger the better in you can control them

Jared

Get some 86# siemen dekas from tom at camp 1320, great deals on them.

It will probably max out at 350hp.

For 500hp: 900cc

Precision 880's!

From what i've found, the above are about right. 350whp on 550's and 450whp on 720's. If you want over 500, i'd go with as close to 1000's as you can find. No need to put yourself on the limit of your injector.

Hey, Tony1
From all the dyno you did, with 900cc and at 500whp, what fuel pressure is at?

tony1

I did 520whp on precision 1000's set at 45psi base. I don't know what the duty cycle was on that pass, but i made 575 on another at 90%.

I just got my Precision 880cc from Art, I was surprise that I pick one up and it's dang heavy.

gas mileage can be tuned to be excellent no matter what the cc is. assuming the tuner is good

BoM

is an external fuel pump a must for larger injectors?

can you run a walbro 255 fuel pump, stock lines, and 1000cc injectors?
