need fuel for 600rwhp

JDMFairlady21

swing for 725cc Injector DYnamics... much better injector. Then go for CJM twin pump setup.

Not to bring up a dead topic, but why do you feel the Injector Dynamics would be a better injector? DW injectors have never given us a problem and they just updated and revised all their latency data to reflect more real world conditions to make them even easier to tune. Injector dynamics is a great company but the 725cc wont be enough without increasing fuel pressure. He would realistically want a 950cc or 1000cc for a 85% duty cycle with 700HP at the crank for a boosted application. DW recently came out with their 1000cc and 2200cc which seems like the perfect fit for his set-up!

Edit: Power is also relative to the dyno used. Inertia style dynos (I.E. DynoJet) will read 10%-12% higher than what I am accustom to. I base all my math off of what we see on a loaded style dyno (I.E. Mustang, Dyno Dynamics, DynoCom FX series).

Thxs guys after talking to Sam I am going with 900cc injectors and 340lph fuel pump

Mr.Squeeze

Who makes 900 CC inectors or do you mean 1000CC ?

Your going for 600whp are you going to the Darkside turbo world ?

Jordo!

Is that with OEM fuel regulator (and therefore approximate OEM pressure) or something custom?

BTW: Assuming about 715-720 to the crank, BSFC of .6, and 43.5 psi, those injectors are going to fall short (or creep up to ~84% duty cycle).

1000 cc's would be safer, but you can get away with 900.

I think Sam told me they were Bosch 900cc injectors
They even have the 900 on the side of the injector
As for going turbo I am secretly preparing just don't tell my wife

Anmvq sent me his cog setup and I going to have my tuner order uprev maf
Just to see if I can get to 14-15 psi before I go turbo In the summer

Mr.Squeeze

Sounds like a good plan going turbo I think you will see that much PSI with the cog's just be careful. The Stillen kit seems to be claiming more motors than turbo car's, I have heard of 4 this year alone.

I don't quite follow the line in bold...

900 cc's will be okay, but duty cycles will edge up towards 85%. A cold night could max them out, so just keep an eye on it.
