Electric waterpump flow?!?! Looking to buy a Meziere (spelling) electric pump, and there are two options.
One is a street version that actually flows more gpm then the race version (55 vs. 35)?!?
I've looked at e-pumps for the SBC and LT1's, they all flow the in the 35gpm range, and I'm sure run hotter then an LS.
So is it really necessary to order the "street" 55gpm unit for the street?

I bought the Meziere 55gpm version for my 1989 L98. If this is a street machine get the 55gpm version. I bought it mainly for the horsepower gain but low and behold it has helped on keeping the motor cool.
In summer with the A/C on and sitting in traffic the temperature would do a slow rise. Now it nevers gets above 180 degrees. For me it turned out to be a win win situation.

The LSx race pump is just that, drag race only version. I asked a similar question directly to our Meziere rep. He confirmed that due to the coolant passage configuration in the LS series blocks/heads, the race pump has insufficient flow for daily street use.

Don't the Meziere(or any E-pump for that matter) have a significantly shorter life when daily driving than a stock belt driven pump.
I started to read on Meziere's site about the expected life being given in hours (even though it is thousands of hours).

When I look at it like that, I see that they can last for a long period of time, but can they last as long as my stock orginal(124K miles) belt driven waterpump?
My car is my ONLY transportation to work and school. When it comes to reliability I feel (in my opinion) that something mechanically driven can be more reliable in some instances than electric parts...
EDIT: From Mezieres Page:
"Purpose built for street use – 3000+ hour life expectancy. " @ http://www.meziere.com/index.php?pgName=wp319
Anyway with 3500HR life pump, I will get about 3500/728= ~5 Years of life...
Where as my stock pump is at about 10Years of service.
