Another fuel rail question

[EmmerichLSx]

I was reading quiks 4.8 high boost thread over on pics/videos. It got me thinkin. My motor is forged, but I still have the stock returnless style fuel rails. I only run 11 psi and I'm pretty sure I'm still under 600 crank hp. My a/f stays good, around 11.5 wot through the whole rpm range. Do you think I'm taking a risk not building a return style fuel system?

I believe it can start to limit itself after a certain amount of power. Talk to Redheartbeat, he is on a returnless and is pushing some good power

There are a few gains from building a return style system.

1.) cooler fuel at the injector usually means more power
2.) garbage gets flushed back to the tank (though there shouldn't be any if your filter is working properly)
3.) fuel pressure can be adjusted

This is assuming you're using billet fuel rails with the fuel going through the rails before going to the fuel pressure regulator.

I don't see any real gains in using the return style on a stock rail other than having cooler fuel.
