Electric water pump drive, any gains in ET?

My results were inconclusive. I kept fighting the "belt flying off" problem through the end of the race season. On the few passes that it stayed on I would say it helped some (a few hundredths in the 1/8 mile), but even those runs were here and there....not consistent to say for sure that it helped. However, cooling between rounds is sure easier now, which is the main reason for one of these I guess. It also cools well enough to drive around town.
