How much power can stock ls3 injectors handle?
Stock injectors can support 600 NA HP, but DC will be over 80% around the 500-520 mark. We have a cam/head C6Z that is on stock injectors currently at 590 rwhp on pump gas. E85 and Some oxygenated fuels will drastically lower the power level you can achieve for an injector.
How much power will stock 5.3 injectors handle?
At the low end of the 5.3 spectrum, the LM7’s 25 lb fuel injectors are going to max out before they reach the 400 horsepower stage, typically around the 380 horse mark. Gen IV injectors, particularly those on flex fuel models, are at or just above the 30 lb mark, which will bring you closer to 400 horses.
How much HP can you get out of a LS3 naturally aspirated?
The LS3 and L99 are both Gen IV, 6.2L, aluminum block, car engines which came under the hoods of GM performance cars between 2008 and 2017. Both the LS3 and L99 engine blocks can be pushed to 850 to 1,000 horsepower.
Can you run bigger fuel injectors on a stock car?
You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.
How much HP can 1050x injectors handle?
The 1050x Injectors you can do 800whp, but not much more than that.
Can I use bigger injectors without a tune?
In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. – running rich and potentially missing).
What happens if your fuel injectors are too big?
It’s easy to fall into the trap of thinking that bigger fuel injectors equal more power, but unless your engine is set up to deal with the extra fuel, you’ll be on a fast track to trouble. The excess fuel will flood the engine and it either won’t run at all, or will be running too rich.
