Fuel Rails

Does anybody know what the power/torque limit is for stock fuel rails?

bluethunderhorse · August 25th, 2007, 11:24 PM

about 500 hp

Euroeater95 · August 27th, 2007, 12:22 PM

Is that at the crank or wheels?

Would one have to replace the stock fuel rails to put on a HCI kit with 24lb fuel injectors?

I dont think so, the numbers that they claim with the hci kit are 300 at the wheels. That is no where near 500 at the crank and obviously not at the wheels. I am wondering because, my car makes 390hp at the wheels and that is close to 500 at the crank. So that is why I am wondering if it is 500hp at the crank or the wheels.

So if I bought h/c/i for a 95 5.0, then I don't have to replace the fuel rail, just the injectors? Trick Flow tells me that I have to upgrade the fuel injectors to put on their hci kit.

Yeah they are right, you do need the injectors. With the H/C/I kit you are using more air due to the bigger valves on the heads and more air flow over the stock intake. So with more air you need more fuel to make power and make it run right.

But a new fuel rail is not necessary? I don't have to change from the stock rail?

no
