Ian, indeed I did. I don't have it in front of me, but it was well within range for 400hp and my application. Fuel pickup is at the way bottom of the tank and you have to pull crazy g's for a long time for zero gas to be picked up out of the main tank for an extended period of time. For a track/race car, maybe I'd go with a different setup, but for a street car that may see an occasional twisty track without big sweepers, this is enough. What's your calculation on the safety factor being too small?
Also, your Facet is a different pump. Check the link. The one I used has been used successfully by a number of builders with higher HP, bigger swirl pots and a track applications.
Best,
Tim
