Is the blower on the Charger just a prop? It looks hokey.

Now that you mention it, I have no idea since I've never seen that car in motion. It just appears at whatever event the guy brings it to. All three FastFurious cars are screen-used stunt vehicles, allegedly. I wouldn't be surprised if the blower was non-functional, but maybe that's just a post-apocalyptic thing.

Look at the belt, it looks like it was cut and riveted back together and there's also a hole in the housing right below the intake. Not to mention the linkage looks all hosed up. [e] I'd love to see under the hood, it's probably glued on top of a straight six

Some quick internet research has the club (Colorado Movie Cars) posting another picture of that car in an album saying that it's a screen-used car from Fast And The Furious. So yeah, almost definitely a fake blower.

It's just occurred to me how wonderfully insane you have to be to sit behind an engine like that as it hauls you up a drag strip. When the greybeard pulls the throttle cable......

I had no idea how that poo poo worked until I saw it, having never been to a vintage drag. It just gets so... violent. It's like giving Dr. Jeckyll meth. So. loving. evil. The whole damned chassis jumps just from revving it.

So what are they feeding into the engine that they 'unplug' after it is warmed up, after which it turns into the devil engine?

It's got a lot less energy per gallon than gasoline so it's harder to ignite, which is why they start and warmup using a small amount of gas or alcohol (dunno which they're using in that vid), then once it's warm they can run the nitro just fine.

And how long can they run it before it starts to over heat?

After the helper line is remover they're burning up to 90% nitromethane - I have no idea what they're burning in the helper line though. Is it just a high octane gasoline, maybe some sort of diluted nitro mixture?

Is that about right?

The advantage of nitromethane is that it carries its own oxygen with it, so you can cram tons more fuel in for a bigger bang.

fyodor posted:So the advantage to nitro is it explodes with less oxygen than pump gas so forced induction produces bigger explosions. Is that about right? Pretty much, it produces bigger explosions because needing less air means you can fill your cylinder up with more fuel. Top Fuel engines are basically running right on the edge of hydrolock at full throttle. Since nitro contains its own oxygen, you can even go beyond the already-ridiculous stoichiometric point and run uber-hyper-mega rich, with basically just enough air to have something to compress on the stroke and not blow the heads off (and that even happens!). And I'm not exaggerating, here's one fuel injector for one cylinder: https://www.youtube.com/watch?v=xGTbQuhhluY

Another fun property of high-percentage nitro mixes is that at a proper fuel/air ratio, you'll be putting so much fuel in the cylinder that if it fails to ignite, you can literally hydrolock on fuel, and pop the heads off the engine. In fact, at ignition, even at high RPM, only about 10% of the nitro in the chamber is actually vapor; The rest is liquid. Ignition of the small amount of nitromethane vapor provides the heat to vaporize and ignite the liquid. Nitro is crazy poo poo.

Since as it vaporizes it should cool down the charge to prevent the knocking hand of god. If so then I think irs mandatory for the immense boost those superchargers must make. Also i thought they'd use crank driven instead of belt drive superchargers.

FWIW a guy that used to work next door to my job fooled around with those things. The engine was a pattern made billet 'hemi', apparently identical between blown and non-blown cars. It used the spark plugs up after one run and he said the atmo one would run indefinitely at idle because of the fuel's cooling effect. The belts only get used a couple of times before getting tossed iirc.
