Jamo, Melling makes several high volume
oil pumps for windsors, one has a threaded allen plug that sets the spring pressure in the pump for the pressure it dumps
oil back into the sump. I have one, mine is turned in all the way, about one turn from what Melling sets the allen "set-screw" at, but when i have wanted to adjust my
oil pressure, i have to drop the pan, and turn it in or out slightly. It never occured to me that you actually can do this with a longer Allen key from the side of the motor, but i suspect this is how it is done via the "bung" in the side of the sump. If i ever have my sump off again, i may try to have this added to my pan.
The sump on the Roush motor in the Superformance coupe is welded up at the Superformance factory, so it is not available as an aftermarket pan, it is designed specifically for the fitment of the Roush motor that is intended for the SPF Coupe. Nice kickouts and trap doors inside, holds about 8 quarts, more of course in the rest of the oiling system.
The details are indeed important when you intend to run with and often trounce the other "Big Dogs" out there. For a fraction of their cost.
By the way, the suspension is not the same one that is in the roadsters that SPF produces, for one thing, the A arms are much longer, they practically meet in the middle of the car, so the suspension geometry is much more stable under high lateral G loads and the resulting suspension deflection. I understand a really well known race suspension designer was closely involved with the suspension design.
I doubt i will ever own one, but i have ridden in the prototype, and it is a fine car indeed. My son, who now has a Porsche of his own, was riding with Bob Olthff at VIR several years ago, on the south course, which connects at the end of the long straight to the North course, if one were to continue on for a few more seconds, instead of veering off to the right to continue on the South Course.
There was a Porsche event then running on the North Course, all sorts of German machinery tearing around. Bob muttered to my son at the end of the straight, "i wish i could continue on to their course, and gather them all up in a lap or two. "
Chris told me later he wanted to say "lets go for it !!
