A recent episode of horsepower sparked my interest.
They were doing a rerun, it was the one the put the engine dyno in the shop. They dyno tested a nice small block and the big block out of that race car nova.
One of the things it showed on the screen was the fuel consumption. The big block used 53 GPH and the small block was like 33.
So that got me to thinking. Where is the line to be drawn on pump size? Naturally overkill is good to avoid lean conditions, but when does usage and maintaining pressure become an issue?
For example a holley blue pump looks like a great choice for a healthy motor. But what real world factors make it too small? G forces, actual consumption, pressure losses?
