Thread: Which high flow water pump?

Tweet

I've had good luck with the Edelbrock and Weiand pumps, can't say about the Flow Kooler, never ran one. No such thing as a fail safe thermostat, if you want something that can't fail, use a restrictor in place of a t-stat--works great on a race car..... It will make for a longer warm up, but that's about the only drawback....

Dave, they've been making them for a few years. By fail safe, it doesn't mean it won't fail. If the heat capsule fails, they lock in the open position. They run 2 1/2 to 3 times the price of a standard thermostat. I had one on a van that went out and it did work. The only way I knew something was wrong was the length of time it took to warm up. I think even Stant is making them now. Cheap insurance especially if you're running aluminum heads.
