You guys with 400 hp+ setups are not in the same situation as a NA Renesis so it kind of shades up things for the others.

This seems like a good idea and I wonder if hydramat might be my next step. At the same time I'll put my s2 pump back in. I need to get my engine rebuilt first though. Or at least out of the car and shipped to a builder so I have time to work on other stuff.

You might consider upgrading the factory 65c pump to a 265 LPH version. This will up your bypass under WOT, but not so much that it’s sucking the cup dry. It will create more siphon effect to keep the pump side of the tank filled with more volume.

For anyone not pushing major horsepower I'd agree with mark. Use a stock S2 pickup with an upgraded 265LPH pump and put a hydramat on the siphon side. Putting a surge tank in the system would help as well.
