GM Pro Series WP for Crates

Question: Looking for a new Water Pump and I see the GM Pro Series that Stewart is selling. Says less than 2 hp @ 50GPM. So has anyone tested this on a crate? I mean we are cutting off fan blades to reduce drag and save HP? Kinda spendy, so just wondering

Ya OK, So you dont have any input on the WP? That was the question. I was always under the impression that a GM 4 blade fan robbed approx 10rwhp verses no fan and a 2 blade robbs approx 5 rwhp verses no fan and a 2 blade doesnt "cool better" it obviously moves 1/2 the air due to surface area loss. It just ends up restricting less air through the rad "at race speed" and therefore you can maintain your cooling and may see a gain, but at lower rpm and speed, it doesnt cool as well because it cant move as much air. But ........ fans have been discussed at length. I would just like to know about this WP if anyone has and input on that.

Dude, get over yourself. All I want to know is if anyone has done any tests on this pump. You Obviously have not! I could give a rats a$$ about your opinion on the fan. If I wanted your opinion on the fan I would have asked for it. This is a post about a waterpump.

not worried about which fans, just get you some of these bad boys and you can run whatever you want.
