Around what horsepower range do the factory 28.8 fuel injectors max out at? I am at 450 rwhp and they seem to be doing fine even with the factory fuel pump. Looking to hit the 500rwho mark before the new year.
Thanks

 

they are maxed now. They are 24lb injectors rated at 43.5.. When you run 58psi like in your car they become 28. The max you should run on a stock ls1 injector is 400CHP. If you scanned that engine your duty cycle would be over 100. To support the HP you are looking for you need at least 36 @3bar which will flow 42 in your rail.

 

Umm ****. Thanks for your input.

 

I have seen 430whp-460whp on stock injectors at 98% duty. How is your cam only, stock ls6 intake, stock tb, stock heads, stock block making 450 whp! That's BS
