I've never named a motor. The LT1 (not the LT-1 from the 70's) and the LS series all came from the factory with compression ratios of 10:1 or more. In this case, we set it that high intentionally. Obviously a boosted engine will make more peak power with a lower static CR and higher boost, but that results in a torque curve that looks like Dolly Parton laying on her back. That's fine for racing, since you can install a loose torque converter and keep the RPM high all the time, but it would truely suck on a street driven car. So instead of a 7:1 static CR and huge boost, it was built with higher static CR to provide decent power even when not under boost, and to give us a flat torque curve. We did use a semi-loose torque converter. The stall speed is 2500RPM and the flash is 3000.
The top speed in the Jeep is very definately limited by the gear ratios. But even if the ratios were higher (numerically lower) you still would not want to go very fast in a vehicle with such a short wheelbase, high center of gravity, and a suspension designed for flexibility, not high speed cornering. Dodgeing a dog in the Jeep at even 30MPH will cause significant sphincter spasm...
Well, diving has certainly caused my wallet to get lighter, but other than that...
One of our first dives was on a very shallow reef. 24 feet max depth. There was a lot of surge too (not current - surge is the back and forth motion caused by waves). Surge moves you equal distances in each direction, so the proper way to deal with it is to ride it out when it pushes you backwards, and swim with it when it pushes you forward. Unfortunately, I was too inexperienced to do this, so I was fighting the surge. And you can never win a fight with the ocean. Between the back and forth of the surge and the exertion, I made myself seasick. Puking through a regulator is several things. It is possible. It is popular with the fish. And it is entertaining to your dive buddies. What it's not, is fun.
In the area around Tulum, Mexico there are hundreds of cenotes (sinkholes). These sinkholes are the entrances to the worlds largest underwater cave system. Dive operators in that area take basic OW certified divers into the cavern area (the area still in direct sight of sunlight, even if that sunlight is coming from a 3-4 foot hole in the ceiling) of some of these caves. There are no scuba police, but the accepted standards for these tours include things like: the guide must be full cave certified and dive full cave gear (doubles, long hose, etc); no more than 4 tourists per guide; everybody has their own light, guide in front, next most experienced diver at the rear, etc. All reputable dive ops adhere to these guidelines, but not all ops are reputable.
Coming out of Chac Mool (a very popular cenote for tourist dives) at the end of our group, I felt a tug on my fin. I stopped and looked back, wondering what I could have caught it on, and there was another diver. Seperated from his group. With no light source. And too foolish to head back to the sunlight. I checked his air (he was using his reserve, but had enough to get to the main exit with us), handed him one of my backup lights, put him in line in front of me, and we headed out. 4-5 minutes later we encountered his guide (not wearing full cave gear) and a woman coming back, looking for him. He gave me back my light, rejoined them, and they headed out. We finished our dive.
They were breaking a number of fundamental rules, not limited to the fact that it took them FAR too long to notice that he was missing.
Diving is potentially very dangerous, but if people stay within the limits of their training and experience, it's really pretty safe. The vast majority of dive accidents come down to diver error, or just plain stupidity.
Reefs are absolutely alive. The reef itself is built up by coral, which is a tiny animal. The surface layers are living coral, on top of the skeletons of the earlier generations. Sponges and such grow on the coral, and the structure of the reef provides food and shelter to all the critters. They're very fragile, and divers who crash into or kick the reef are not very well thought of. Inexperienced divers are encouraged to learn to control their bouyancy and trim, and since the reef can "bite" (fire coral and various toxic to the touch critters) most active divers will pretty quickly learn not to touch.

As I was taking this picture, I saw this womans hand come into the frame. She was fairly new, and was clearly about to touch the reef. Problem is, this particular reef is actually a rockish. Their spines are venomous. Generally their stings are quite painful, and occasionally people who are particularly sensative to the venom can be sick for weeks. I was able to grab her hand before she grabbed the rockfish. Back on the boat, she made it clear that she though I was overreacting. I showed her the picture, but she never did seem to "get it".
We don't dive with her any more. She's an accident waiting to happen.
