my virtual engine, with the parts i have collected:

Turbo Piston engine BSFC .60Fuel Presure 43.5psi4x550cc injectors4x370cc injectors (secondaries)15% RWD Drivetrain loss

493 HP419 WHP

thats what the calculator says my fuel system can support and estimated power out put.

it also goes onto say my recommended fuel pump presure.. cool

i require a minimum of a 186lph fuel pump to run 25psi boost... well a 255lph pump is a good safety margin, and i should be running about 84psi fuel presure.

cool calculator, kinda matches what i am aiming for,

not to shabby for a guestimatei need to bring it to a real dyno. Does anyone know where i can get some software and cables so that you can plug it in to the back of your computer ECU and then into a laptop and get readings. I had a site that sold cables and software with some cool visual stuff but i lost it.

Not a bad foundation for doing equations on your set-up! I'd say in both tests I did for both my cars, it was off by about 28%.

This is on my girlfriend's old car:Fuel Pressure 43.54X526cc injectors85% controllable limit15% drivetrain loss283 flywheel HP241 wheel HP

This is definitely off quite a bit because with that same set-up the car put out 312.5whp which equates to 367 flywheel Hp. Still a good reference though.
