Been searching the interwebz for a while trying to find options for larger injectors for the 4.8.

Will be running e85 aiming for 1000hp, so what I've found is that they will need to be larger than 80's.

What are some good injectors for a decent price? Should I stay with the stock fuel rails or get different ones?

 

1000hp on E85? I would say you will be pushing the limits on the stock fuel rails. Are you planning on doing this in a 4.8? I hope you plan on a huge fuel system? Swap to returnless, and run big lines and fittings with a huge pump. Basically everything needs to be upgraded. As for injectors I would venture to guess these should cover it....

103lbs should be close, but with e85 it may need more. If you need to go bigger you will be looking around $1000.

 

yes, bigger fuel pump, surge tank, bigger lines, I know what I'm doing for those, I'm just stuck at what to get for the rails and injectors and which ones actually fit.

Will you be running meth? That will reduce your injector issue.

 

I will be running meth as well

 

bump for more help

 

What are you planning on doing to a 4.8 to make 1000hp? Good luck

 

22-25lbs of boost and possibly some nitrous to get it there...
Will be getting forged pistons and rods before I turn it up that far even though I've seen some make 800-900 on stock bottom ends

 

Those injectors I posted should work fine to get you 1000hp if you are spraying meth as long as you are running 4bar pressure or more and your fuel system is all good.
