The gears, the only thing different is the material and another process we use to make the gears stronger. While I haven't tested the VHR yet, I don't see why we cant replicate what we did with the DE. I hate to put it like this, but you can buy a nismo, know that they fail, and be out of pocket $1400. If not, you can go with our pump, save money and at least get the same performance if not better, and have billet gears and a billet back plate. We are using a Nismo pump as our base, to make this an even closer comparison, not just a regular VHR pump.

Well i guess you just need to start testing and post the results. Sounds like a great product. Opening up the block to get to oil gears, doesn't seem like something worth doing on a product that hasnt seen any time.on at the VHR platform.
