That's almost i.possible to do. At the dive school we had a 10m dive board on our 40' pool. You might make 10-15' deep, but buoyancy wont let you go to the bottom. Unless you are wearing a lot of weight belts....

Doc

I just checked and the "max depth of the pool" is listed at 20'. So I was off at 25'. But it also was not my imagination that my feet touched the bottom and I pushed off of it to get back up. Im GUESSING the bubbler system allows you to cut through the "water" a lot differently than if it was just straight water with no air bubbles.

All I know is it hurt with a bubbler at 10m so the video posted above, that looks higher than 10m, looks like it would hurt a lot more.

In CA when they banned the AR and AK, the 1919 was legal as was the Ma Deuce (semi auto)

then CA banned new mags over 10 rounds so the belts were an issue and banned 50 BMG rifles (updated)
... but the Ma Duece is not a rifle so it’s ok

I wonder how much each MPH costs???
From an ME class years ago, once a car reaches top speed - say 140 in a mustang, it would require roughly doubling the HP to add 10 more MPH

altering the coefficient of drag was way cheaper. Also making the car skinnier was cheaper as you had less cross section for air resistance

thus top fuel dragsters are skinny

Doubling the engine output normally reduces its lifespan to unacceptable levels in a street car




The Porsche 911 maxed out air cooled (oil cooled) and had to switch to a more modern design to make more power


the high output 911 air cooled motors can easiest cost $100k

Porsche went to the water cooled 911 as they had to use 4 valve heads to meet new emission standards that could not be attained with 2 valve heads. They knew from racing that they couldn't air cool 4 valve heads.

In “regular sports cars” porsche, Ferrari.

Not a Miata with crate motor, but a car that can:
Brake
Handle
Proper safety /able to be

250 HP gets you to 140-150
400 HP gets 170-180
500 HP gets 190..almost 200
600 HP gets 200-215
700 HP gets 220-230

there are exceptions and such but if you buy a modern sports car with those HP ratings those will be your top speeds.

Been there...done that.
