Bob,. What type air filters are you using?
Several GT40s have the dry sump tank mounted there including some handled by Olthoff Racing. There has been no concerns from scrutineering by SVRA or HSR to date.Looking really good. I’m a little concerned, however, that your oil tank is so close to a potential source of ignition (exhaust). The concern really manifests itself when looking at it from the perspective of a racetrack scrutineer (which I once was) and judge the car’s crash worthiness. The heat containment shields may well mitigate the risk.
That's because some of the folks in SVRA and HSR are more concerned you have period correct decals, bias ply tires, your paint code is period perfect, and got your jaunty cap on at the right angle than they are about car safety prep.....There has been no concerns from scrutineering by SVRA or HSR to date.
