Now we are talking hyperspace! (Race across the desert)


Hey, did anybody else dig the race across the desert scene in this movie? I swear, the guys who made this movie were definitely trying to say that the old-school muscle machines can definitely get you where you need to go...if you're trying to save the world that is!

Mike, Vinnie and Ellie hopped into Michael's GTO and quickly took off down the highway in an attempt to keep the quantum device's energy from reaching the power station, thus creating a bigger wormhole. At first, they're only doing 100 m.p.h. and Vinnie groans, "Aw come on Mikey, I thought your G-Toe had more meat under the hood than this!" The energy already had a headstart and unless Mike pulled something outta his hat, the town was finished. When Vinnie says 'hit the blower' Micahel does and the car takes off like a lightning bolt! My eyes just lit up in amazement as the muscle machine began to pass the power lines at 120 m.p.h.! I also loved the part where Ellie is sitting in awe and says, "Michael, I don't know about this! This is too fast for me!" and Vinnie tells her it's just like and E-ride at Disneyland. That was funny!

The GTO definitely is a high-performance machine in this movie. Anybody else loved this scene, please post! I'd love to hear your responses on this scene!

This was always my favorite part of the movie. A couple times I popped in the DVD and just watched this part.

reply

Fo' real?! Do tell, do tell! What did you like most about the scene?!

reply

Well Iv'e always been into muscle cars so I just thought it was cool with the "blower" and all. The way that the energy was traveling along the wires was really cool looking too.

reply

Fo sure! I love muscle machines too! That GTO would look great in a showroom. I wonder if this car was ever auctioned.

reply

They probably used a few different cars for the movie. I'll bet that the prime car used was probably borrowed from the owner. That's what they usually do for movies involving classic cars rather than try to buy them. Although this car was not a really old classic at the time of this movie..so maybe.

Yeah, admittedly, that was one of my favorite parts. But we all know it wouldn't be possible in real life.

One problem. You cant turn on and off a supercharger...perhaps nitrous...but he says "Hit the blower!". When I was little it was cool, and still is dont get me wrong...however you cant turn on a blower, its always on! LOL

Yeah, they showed the same thing in a couple of other films. I think the first, "Mad Max," movie and an old Chuck Norris movie called, "Lone Wolf McQuaid." I talked with a couple of my buddies about it a while back. We came up with the idea of hooking an electric clutch pulley, like those used for air conditioning compressors, to the blower. This would effectively make it switchable but nobody really thought that it would be practical. Nonetheless it was a really cool scene. Let's just chalk it up to the magic of Hollywood; you know like a guy firing fifty rounds from a six-shot revolver!

reply

Right, it's possible but not practical. You'd have to have a secondary fuel mixing system (carburetors or injectors) plus a second air intake system. Since the inside of a supercharger is made of two tight fitting rotors that compress the air/fuel mixture before feeding it to the engine, no air or fuel could get in unless the supercharger was spinning. That would make the engine look like a huge mess.

Not only that, but superchargers don't even increase top speed. Regardless of the ammount of power an engine makes, it can only spin so fast before it starts to lose power usually caused by the mass of internal parts not being able to change direction any faster. The lifters start bouncing off the cam lobes and the timing goes crazy.

It makes for a cool scene in the movies, but it's all just for show. Kind of like the dinosaurs in the gym.

Kaylee, what in the sphincter of hell are you playing at?

then howcome tuner cars with superchargers have a higher top speed listed than when the car was stock? they do increase horsepower and in turn can increase a cars top speed

It's because the engines in tuner cars have a lot more modifications than just a supercharger. They have different camshafts, different timing, upgraded ignition systems, and more.

The ammount of horsepower an engine makes really doesn't have anything to do with top speed. Imagine you have two identical cars. One has a 200 horsepower engine and the other has a 500 horsepower engine. Both those engines are spinning at 5000rpm. If the transmission gear ratios are the same, the axle ratios are the same, and the tire/wheel diameters are the same, then both cars will be traveling at the exact same speed.

The higher horsepower engine will launch the car faster and get up to top speed faster but it won't increase the top speed of the car. It's like if you were riding a bike alongside a child. You'll get off the start faster and accelerate faster, but if you and the child are pedaling at the same speed then you'll be going the same mph even though the child is much weaker.

reply

so in your scenario both engines are limited to 5000 rpm? If so then I accept that. But if a car is modified to have greater horsepower and if its compared to a stock vehicle where the gear ratios and axle ratios are the same then the higher horsepower car should not only accelerate faster but have a higher top speed. Otherwise how is the top speed of a car increased? Some can be done with better aerodynamics and have less weight but with no greater horsepower the top speed will not increase that much. In the case of the movie I think the depiction of the supercharger increasing the cars top speed is correct. I think the producers of the movie knew this or otherwise they would use something like nitrous

MC7791,

The primary way to increase top speed is by changing the gear ratios in the transmission and/or the differential(assuming you have a rear-wheel drive car). For example, smaller differential gears (eg 3.55's) are good for speed, and taller gears (eg 4.10's or bigger) are good for rocketing off the start line. The 4.10 means that when the drive shaft makes that many revolutions, the wheels make 1 revolution. Hope this helps:)

reply

yeah you are right but I think a cars top speed can still be increased by increasing the horsepower. Also if 2 cars are exactly the same with same basic weight aerodynamics, hp, and same rear axle ratio then if one has like 50 more horsepower would it have a higher top speed? I mean cars that have top speeds of say 180 plus mph besides having the smaller diff gears also have a good deal of horsepower compared to cars that do not have the same top speed

There is this website I was looking at about how engine power and top speed are related. Have a look.

reply

yeah basically that said what you were saying but also that you need significant power after having the gear set you want to increase top speed. that is also what I said. I already kind of new that. thing is getting back to this movie so many muscle cars had so much horsepower but the gearing always favored using all that power in acceleration where as time went on cars with less horsepower had overall higher top speeds. I wonder what all the performance specs were on the GTO used in the movie and whether or not the supercharger was always on or was activated with the switch as shown in the film

Just got my copy of this movie in the mail. But some parts of the movie seem to have been cut out. For example, when I saw this movie on tv 20 years ago, I swear that the GTO chasing energy scene was longer. When I saw it on tv, I remember Mikey was power shifting while starting the chase. Is this on anyone else's copy or am I thinking about a different movie?

reply

Why race the energy in the first place? Just blowing up any tower would break the connection even if it was ahead of them.

reply

haha! never thought of that . simple really
