sure can , the pan was built by My racecar builder . I call Ian Jenkens from JPP a racecar builder in that he does most stuff in house. Not only chassis , but all fabrication for racecars , oil pans , tanks , trans building , electrical , electronics etc etc.
It will be interesting when we get it on the dyno , to have a look at what the oil is doing. This has got three flat trays with a scraper lip on each , and also has two chambers and two gates. I was losing oil pressure on the last engine just after hitting max negative gees when the chutes blossomed in the braking area. The data logger showed it quite clearly that it dropped from 100psi through the traps , rolled off it and we had an rpm related drop to 70-80psi , then chutes and a drop to 30psi. All the oil was in the covers and the valley , with little left in the sump for good pickup. The two gates gates are to try and keep more oil in the rear of the sump around the pickup during shutdown.
The Boss 9 also looks like its going to have drain back problems ( specially when compared to my old A429 ) , so I am going to carry up to 3 gallons ( 12 litres ) initially on the dyno to see how much oil gets pumped into the valley and covers and how bad ( or good ) the drain back is. I use a 30W60 racing oil as I believe big engines need big oil.
The two peice design is so I dont have an excuse not to regularly check the Aluminium rods and bearings. With an O Ring seal and easy to get to fastners , it can be done in a half hour.
Not a cheap oil pan though!!!
