How much work is this to install? I have read some of the post here about these things and spoke to a tuner who said its good for 7 to 10 HP. Any of you DIY'ers install one of these your self?

Straight forward install. You will gain a couple of HP because you've eliminated the belt driven pump and maybe a couple more by reducing the engine temps (assuming you change the t-stat and reprogram the fan temps)

I would not do it for the HP gain. I would and did do it when I did my H/C. I raised my CR to 10.9. I live in Vegas 110 degree + summers and I wanted the benefit of full coolant flow even at idle or stopped in traffic.

Never even thought of that, when you stop the electric ones keep running quickly right? Smart!

I was looking at one of these? Any concrete numbers from users?

I was reading on these electric water pumps and every one keeps pointing out about the same 10 HP. Seems like a general opinion.

You will not get 10 rwhp. You might pick up 4-5 hp at most

Hi Guys,
Don from Meziere Enterprises here. When we developed this pump we went to Thunder Racing for dyno testing. They were kind enough to do the swap and testing for us. Mechanical pump / Electric pump / back to mechanical to verify findings. The results were positively 11-13 HP at 6000 RPM. That has been the findings from a number of magazine editors since, including a recent test that will be coming out in 'Vette magazine very soon. They are backed by a 2 year, unlimited mileage guarantee also.

The only thing keeping me from an electrical pump is the belt routing. I believe the LS engine pumps have an idler around the pump where the mechanical pulley would be. I'd love to see that on the early chevrolet water pumps and I bet they would sell alot better since belts wouldnt be an issue. Not to mention you can run your water pump/fans between passes at the strip with the engine off.

The belt routing is the same. Even uses the stock belt. The outside of the Water Pump is a idler pulley that spins.:cheers:

11-13 HP at 6,000 RPM's is not to bad. I really don't get my car up to that level of RPM's. Is it safe to assume that at 3,000 RPM's the gains would be half what you said? What is the primary reason people install your pump? Is it more circulation of fluids? Thanks you.
