Yes, too hot that Steve, some rake angle on the rad makes it far more efficient and possible to use a smaller rad for less drag, the manufacturers stand them upright only for 'packaging and space reasons' but i dont think thats whats going on with yours as you have good rad area, a 'bottom breather' system in a Beetle can be difficult to extract the hot air, i use gills in the lower front wings to extract the rad air into the low pressure area behind them, upward venting is the way, but not easy on a street Bug without surgery, mine splits the venting air over and under, but its easy with a track car, i use additional upper vents in the front 1/4 panel fuel filler neck area, both sides are in a low pressure area to pull the hot air out, but its not descreet, i run at 80c during events, after, it heat soaks to 90c in the paddock where the fan cuts in, so you need to pull the air out more from the under tank and lower wing areas i would guess. nearly there
