I see it has a stock oil-pan, what sort of oil-control does it utilize?
If you are referring to the yellow Havik car I do not know much. The Belgium team were active in road racing a number of years ago. I do not think the race anymore.

Sterling, for best flow straight runners is the optimum but it is a problem to find room under the hood. Another question is at what rpm shall the intake duct be tuned? I do not know how high you expect to spin your engine? Peak power probably at around 7500 rpm, peak torque probably at 6000 rpm. For a hot street engine I would tune for peak torque which will be a tuned length of 38 cm or 15 inches. Shorter length will add peak power but shorter than 33 cm or 13 inches will probably not bring anything more.
That looks amazing, the headers are making me jealous. I’m looking forward to hearing how it drives once you’ve got it installed
Ive got a modified S62 engine and I’ve followed some of the developments made. I haven’t seen anyone post dyno results with short runners fitted, except when supercharging. Not being any kind of expert I stand to be corrected, it seems most S62 engines even when tuned and modified still keep the longer runners.
We turbocharged a bone stock S62 engine using a custom single TB intake with much shorter than stock runners and made 500 hp / 830 N.m on E85 and 5psi of boost.
The engine might have made more torque with stock length runners but may also have melted its chocolate rods, and 830 N.m was already more than enough for an emptied car run in drift events.
FWIW you can still make a lot of power with practically *no* runner length.
its just that longer runners can help the overall engine make more power in certain rpm ranges (which can be balanced against other things to raise and broaden the power curve).
FWIW look at the early 90s GM LT1 engine...total length from valve seat to "plenum" was maybe 8".
but due to the decent heads, mild cam and big displacement it still makes a nice power output (below is at the wheels).
any 928 with another 50+ CFM in the heads over the LT1 will be a beast.
