running out of breath in the 1/4 mile

Any electric pump will need a relay in the circuit. Very easy to install. I recommend "that pump" because it's a good compromise. It performs well and it won't put you in the poorhouse. It will require a regulator though and I highly recommend a return line.

Here's the main point. Yes, you can probably get a mechanical pump to work WHERE YOU ARE NOW. But remember you upgraded the car from what it WAS. How much longer before you upgrade again? Isn't it a peg leg? Don't you plan on a sure grip? You got any ideas about slicks or drag radials? When you get the thing to finally launch GOOD, that fuel pump is really gonna be workin. HARD. You get what I'm sayin?

Why use something basically for a band aid IN THE NOW when you can make a pretty affordable upgrade that will work WELL into the future?

That's just my line of thinkin on it. Not tryin to argue with anybody here........just trying to tell you what "I" would do.......already done, actually.

If you want to properly diagnose it, nothing in the world wrong with that. I think somebody already suggested teeing into the fuel system and taping a gauge on the windshield, right? Try it. Make sure you have a second person to watch the gauge.
