All I know about it really is that the DE guys who tested it never found it to hold up to real use, and ended up having to go dry sump. I would assume that the VHR product is really similar with perhaps just a different volume. It is also a hint that its not the best pump since Nissan didnt use it in any shape or form on the VR38, and went with a wet sump pump down in the pan that runs off a chain. There are so many similarities between the VR and VQ that I would figure they would use the same pump if it was any good for extreme applications.
