Smile The facts regarding the RE-medy RX7 water pump

I'm happy to be here and to respond to any questions regarding our parts and in particular our RE-medy pump. If the RE-medy pumps were not THE BEST at what they do then I would say nothing from our company is any good; that's how significant of a part it is. I am the main instigator that got this product developed so I can comment on a few aspects of what it is, why it was developed and what it does.

I've owned 2 94 FD RX7s and 1 05 RX8 personally and know that their cooling systems are their 'Achilles heel'. There are many components that make up a proper cooling system and a good water pump is only one of them. The extent of my knowledge of these systems was really quite limited until I had several conversations with Mr Engman on the topic. He was working on some pumps for some significant people at Mazda at the time (That I may not name) and we were finding that the RX8 impellers were less than optimum to say the least, resembling blender blades. We were also under contract to build motors for a race team in the KONI challenge and Mr Downing (The other owner of our company) also had a renesis based engine project that we needed to create improved water pumps for. Some of the previous years' impellers were much better designs and we used some when we could. This required some machining and the supply of those were also quite sketchy. MNAO was unable to source the ones we needed from Japan and they were still less than optimal. One Saturday morning at a business breakfast with Mr Engman I suggested that we make our own. We researched the possibilites from there and after consulting with our friend Dr Iannetti regarding materials, began building these units. They are similar to the pumps that were used on the R26B 4 rotor and absolutely flow more. The first principle that allows this is clearancing: The closed back design and vane positioning is much better on our pump. You can look at the edges of our impeller in relation to the pump body. In every direction we have tighter clearances so that water can be properly gathered. The water that is drawn to the pump meets a cone before being directed to the blades. The important aspect of the general helical shape is related to the release of the water being gentle in order to avoid cavitation. This pump came from a lot of research and a lot of years of experience with rotaries at every level and is absolutey superior at moving more water out of the block more efficiently including at elevated revs.

At some point we decided to do the version for the FD and have been very pleased with the results. The testimonials have been very rewarding. These are the rotary cars that need it the most, generating the most heat and having sub-par pump designs from the factory.

I am very pleased to be associated with a performance option for our cars that actually does something without smoke and mirrors like some companies utilize every day in their marketing.

Thank you to all who have used us and considered us in our interesting past through to our present stage (Which is very exciting to me).
