Review & Pics - Mazmart Water Pump

Review:
Kind of pricey, but it promises to alleviate a bunch of overheating issues. Overall I am confident that this piece will live up to its price tag. Quality is excellent, shipping was great, and the phone service was prompt and friendly.
Install took about 1.5 hours, I went ahead and changed the coolant while I was at it. All the bolts on the water pump were 12mm, with 10mm bolts for the water pump pulley. Spillage wasn't too bad when I had already drained the fluid out, soaked a rag that I placed underneath the opening, but no massive floods.
I would rate this install at slightly harder than the agency power pulley install, since you are dealing with spilling liquids.
Everything went smoothly, except, when you are replacing the new water pump, dont put the pulley on before the pump is in the car, if the pulley is in place you wont be able to slide a bolt into place.

Comparing the two, the OEM fins are taller.
If flow = surface area and pitch. Then it looks like OEM has this one beat. High RPM operation on the other hand is a different story as the Mazmart pump appears to have a more smooth transition, which I believe would be very efficient at higher RPMS.
At low RPMs I am doubtful that this pump would flow more than the OEM, must be why they persistently suggest not using under drive with this pump.
Maybe less efficent at rpms under 2500, everthing above and the smooth curves of this unit beat the OEM hands down.

I have the pump too, except that I dont have underdrive pullies.
the water temp for my car is about hmm between 82-100 celsius.
it goes up to around 100 ONLY if I hold on to 9K RPM for maybe couple of minutes.
Oil temp usually sits lower than water temp.

You can use that comment wherever you like. My point is that the factory pump is adequate for those whose cars are stock but, even then, the Mazmart pump is a nice piece of engineering and, for $250, is a good insurance policy to have if you are going to track your car. A couple years ago I raced at Road Atlanta and I had the stock pump. My engine never saw lower than 6,000 rpms and the cooling system was fine. However, it would have been nice to have this pump back then.
This looks good and have been keeping up with the thread and all.
This may end up on my list real soon!

I know, hes not the one recommending agaisnt using the pump with underdrive pullies. I am.
And I am for good reason. The temps spike quickly while at idle in 85 degree weather. Driving in 100 degree weather and idling in traffic in 100 degree weather for 45 minutes are two very different things.
Already the biggest flaw with underdrive pullies are their performance at idle. No one complains of the benefits of underdrive pullies while they are screaming along at 7K down the interstate, the only pains we hear are from people at idle.
And now with the new design looking less efficient at lower rpms <2000.
Quite frankly it could be the best design in the world (which it really is, and this should definetly be on your mods list if you plan on tracking your car). But the hard reality is like I stated, good design won't help at lower RPMs, flow = area x pitch and the OEM pump beats this pump in that category.
So, if you track your car and want the best cavitation protection get this.
If your car plans on seeing a lot of traffic and isn't cavitating on the track, then get a new radiator.
Ideally both, a better radiator would prevent any potential problems at idle.
The best setup you can have is this pump and a higher efficienty radiator!!!
If your going to buy only one(radiator or pump), then heed my advice
