Electric water pump drive, any gains in ET?

On a very consistent 10 second car, I didn't see any ET/MPH improvement replacing a stock parts store water pump with a high dollar meziere electric. The alternator was installed, but not charging when we made passes.

It was pretty disappointing as I recall. The car was a LOT easier to cool down between rounds, though. We ended up having to put a heater on it to keep the oil at temp. ;)

At some point I tried one of the moroso water pump drive deals and would shut if off while going down the track. Didn't get anything out of that either.

I have consistently seen improvement with an electric fan (which has varied a lot based on the car it was on), but of course, the fan isn't on when the car goes down the track.

I'm thinking of putting the pump drive deal on the Dart, just to be able to cool the car better between rounds.
