You just have to keep stress/strain in the plastic region. A ME could elaborate on how hilariously improbable that is, but there you go.

I've pulled apart a couple of old inline sixes that were bent. Generally, the front of the block sags down in front of the engine mounts. It's not really noticeable until you strip it down and straight edge it though.

I know. I was asking for some empirical evidence since outside of very minor warpage, a block is going to splinter and shard before the whole block goes pretzel.

Get just throw some duct tape on this whole conversation and continue on our merry way.

They don't bend, they break. We have to show this guy that thread.

I can -not- remember which thread it was. These photos need to be shown to that person, stat!

edit: for huge post. make smaller.

It was the dude with the twin turbo viper with the chute, I think. He was talking about an SRT10 truck, where he had trouble taking the main caps off after some shady engine work or something. I don't remember the details, maybe he'll post or someone else will find his original post.

would that only happen when you were winding the gently caress out of it? or if it was supercharged? or just high mileage or?

Poor metallurgy back then. Metal strengths have changed over the years. These days you can have thin sheets of metal that has the strength of thicker sheets back in the 30s and 40s.

I think that's due more to the inherent mechanical imbalances in a straight-8. Crank whip anyone?

Wikipedia posted:

Also, due to the length of the engine, torsional vibration in both crankshaft and camshaft can adversely affect reliability and performance at high speeds. In particular, a phenomenon referred to as "crankshaft whip," caused by the effects of centrifugal force on the crank throws at high engine rpm, could cause physical contact between the connecting rods and crankcase walls, leading to the engine's destruction. As a result, the design has been displaced almost completely by the shorter and sturdier V8 engine configuration.

vvv I think it's his glove. Probably more blood if the hand came off.

Interesting. See I was educated that I-8's are gone because of the ridiculous packaging that they required in the engine bay.

Then again, If you can package a I-6 transversely these days, perhaps a longitudinal I-8 isn't that out of the picture. I guess however, it's the same length as a V16. So you might as well crank one of them if anything.

Also, with vibrations I understood that I-8 had a completely balanced second moment of vibration (As it is two I-4's together). Much like a I-6 or any boxer engine.

And that is why you can have v12's and v16's at any bank angle.

Listen to your friend Billy Zane. He's a cool dude.

quote:

From what I heard from the guys working at the dealer, they saw this moron drive up the dealership driveway on 3 wheels with sparks coming from underneath the car. Apparently, he had smacked a curb a couple of blocks away. He obviously hit the curb VERY HARD. As he was getting closer to the dealership, the front wheel and suspension actually snapped off of the car leaving him limping on 3 wheels. Someone else had to pick up the fallen wheel and strut and bring it to the dealership because it was laying in the middle of the street.

I saw one similar to this that was one of the funniest things I've ever seen. It was slightly less dramatic, but something under the hood blew and the hood just sort of popped up a bit in a puff of smoke as the engine wound down in a sort of sad sounding whine. I couldn't stop giggling at it, it was like the automotive horns.aiff. If someone knows what I'm talking about please god link it.

BMW either has the strongest wheels ever made or the weakest suspension. I'd expect a lot more wheel damage for the suspension to fall the gently caress off, speaking from experience.
