We use to have races out to a tree and back , at this one lake (well we used to call it a lake, compared to the rest of the U. S. , it's a pond or even a puddle - but for us, we call it a lake). We used the tree as a turning cone. (the water level was real high for a few years)
We really needed snorkels, but if you got it right, you could push a wake and have a void infront of the grill.
Atleast back when I did these stunts, I had 40K and + on my 80 yota, I paid 7K for and another 5K into.
It was amazing, as long as you kept moving fast enough, the water never came in my door seams. My intake was at the very top of my hood.
Only once did I hit a rut, the nose dipped, and took on just a tad bit of water , and stalled. And then water came in the door seams.
Apparently not enough for hydro lock as I found out, seemed mostly the ignition, it was lower than the intake and not water proofed. Once you lost that wake, the level rose in the engine bay.
I was able to use low, reverse (manual) and the big batteries I had for the winch to power the starter to back out to dry land (a true electric vehicle ! ). Started the truck, parked it on a hill and let it drain.
Next day I pulled out the carpets and seats for the day, and it dried out well. Never smelled.
Even my linear amp for my CB tried out well, it was under the seat.
And yes, back then, beer was also the reason to start and particpate in such races.
