For the sake of discussion, I am assuming you are talking about a carbed engine. If that is so, the primary advantage is that you eliminate vapor lock by mounting the electric pump near the tank. But in a hot rod scenerio, where an engine demands more fuel, you can bump up to one of the electric race pumps, and get the fuel your engine needs.

I've never run nitros (but I will) and everything I read is that nitros and fuel starvation = a blown engine.

I guess there are high output mechanical pumps available, and for most street driven engines one of these may move enough gas. Maybe the thing to do is run your electric pump through a mechanical pump? I think I've seen this done.

I'm running a Holley red pump on two of my cars now, and I like them. My Son just put a Holley Blue race pump on his '29, and is running it through a pressure regulator.

If you install an electric pump, use a good filter before the pump, and wire it with some shut off ( oil pressure sensor) so that the pump turns off if the engine stops running (like in a wreck) It isn't real cool if the pump keeps running when the car slams into something.............k-boom?

I'm sure some other guys on here have more experience with both pumps in high performance applications, so we will see what they can offer.
