Fuel Delivery Systems Hi all,
First time poster.
Just had my 5.7 LS1 engine rebuilt and ran it for 5 minutes to check for leaks temperature etc. Now it is ready to go to get dyno tuned.
Motor has had extensive work including Scat Rods, Forged Pistons, Roller Rockers and a Lunati Voodoo Camshaft 232/238.
Running a 3500 lock up convertor and 3.9 gears.
Question i have, is post dyno which i will have the car back next 48 hours, is when do i know if i need to upgrade fuel injectors, pumps etc?
Is there a general rule of thumb for what HP you need to upgrade?
Thanks
Jamie

your probably on the verge of maxing out your stock injectors as it sits, your tuner should be able to tell you more about it. I would think your stock pump should be fine as long as you dont make over 400hp with it. An A/F guage is a good idea to keep an eye your fuel system to make sure you dont run out of fuel.

Thanks for the update.
Can i ask what size are the std fuel injectors and what would be the better option going upwards?
Engine builder was conservative and indicating around 280-300KW at the treads. (Nearly 400HP).
Hoping for more, but guaranteed it will drive nicely
