fuel rail upgrade?

[Black70Fastback]

at what point do you guys think it would be necessary to get high flow fuel rails? like a horsepower level? i figured stockers could go a loooong way.

It seems to be most common for people to replace them after 600 RWHP. I don't know if they are being exceeded before then, but 600 seems to be the most common time to switch out. Our fuel rails are pretty big....

Yea the stock ones are good up to about 550rwhp

I've got Mallory fuel rails and no where near 600hp. I switched because I bent one of the stock ones pretty bad pulling my motor out of the car, so I figured I might as well upgrade them. The Mallory rails are huge.

I just read on turbomustangs that the stock rails are good to about 1000 hp, it's the pumps you need to focus on.

well im looking at about 450-500 horse at the flywheel so it sounds to me like ill keep the stock ones. i will also be getting a large fuel pump. i already know about that.

its kind of an odd project i got goin on.
