Has anyone tried the fuel rail kit Auto Atlanta has in thier catalog? The description about it delivering more fuel than the original makes sense, I'm just wondering if anyone has experience with it? Good? Bad? Worth the $190?

I could see this being effective if the injectors being used were 42 lb/hr on a 350 HP Turbo engine... BUT then you wouldn't be using stock runners or injector positions.

A stock injector can't move as much fuel as the stock rails can.

My only gripe with the stock rails is the fact that can chaff against the engine sheetmetal and rub holes into them that can leak fuel and burn the car to the ground... These units would resist that, but they are kinda clunky and I'd be afraid that the added mass of the unit would be hard on the rubber injector hoses since there isn't any support of the fuel rail.

George, send me a pair and I'll share the data here. I have an engine coming up using stock FI and another after it using a stock plenum and runner with a 30 pound injector.

The stock unit is lighter and lighter is always faster. :-)

Jake; I don't understand. If there was a situation where the fuel pump couldn't proivde enough fuel to the injectors, the fuel pressure will drop no matter how much fuel you ahve in the rail resevoir. How would this be acceptable? The lower pressure would certainly degrade performance.

What am I missing???

You're not missing anything. Doesn't matter how much reservoir you have. Only matters how much pressure/flow the pump can provide through the system. Adding extra reservoir capacity does nothing
