Erm..

Hey, I've got a couple questions that I've been wondering about. And I figured if anyone could answer them, it would be you guys. These questions are probably kinda stupid, but here goes:

What do you call the thing that comes out of most muscle car hoods. I believe it allows/forces air down into the engine..

What's a hemi? It's a certain type of engine that was used in older car's right? If so, what's the difference between a Hemi and our current engines? When someone says, for example, 300 something Hemi, does that mean it has 300 something hp?

Oh, and this questions probably belongs in the Manual/Automatic thread, but I'm just going to post it here anyway. So if you were racing with a Manual against a automatic. The same exact car, but lets just say it's a 5 speed manual against a 4 speed auto. (Because auto's tend to get watered down when you switch the transmission.) WOuld the Manual win? What if you used technics like power shifting or something like that. (I believe it was mentioned in the Auto/Manual post..)

Thanks.

The manual win if the manual driver had any sense of driving at all.

if the automatic has a shift kit intalled it would win because the computer could shift faster than any human could....

1.) It's either a hood scoop, or a blower.
2.) Hell if I know. I don't like old ass cars so I don't waste my time reading about them. As far as the '300 hemi' part they're probably talking about how many cubic inches the motor is.
3.) It actually really depends on the car. MKIV Turbo auto's are faster in the 1/4 due to being able to brake-boost off the line, plus they're not as hard to launch as the *****y 6 speeds. I'm pretty sure an automatic T/A would rip my 6 speed a new one if the auto driver new how to launch properly.

If you're talking about a mid 90's Mustang GT, or a Civic or something, then the manual would probably win. Like I said, it depends on the cars.

Its a blower, basically a glorified air induction system. Kinda like a big air inktake to keep it simple. It adds more boom to a super charged car.

What's a hemi? It's a certain type of engine that was used in older car's right? If so, what's the difference between a Hemi and our current engines? When someone says, for example, 300 something Hemi, does that mean it has 300 something hp?

Not sure about the hemi but the number before it is how big the motor is in cubic inches.

there thats all I got.

 

[StevieMo]

Hemi stands for Hemispherical heads.

 

[ShobThaBob]

i believe its called a hemi bc of the hemispherical combustion chambers.

 

[advanR]

he said a 4speed auto versus 5 speed manual. i dont care how quick the auto can shift (in most cars isnt the auto shifting slow as hell?), the manual car with its closer gear ratios will win.

 

[skylineGTR_guy]

nope I've seen a stock car with a five speed vs the same exact stock car with a 4 speed but the 4 soeed had a shift kit and the auto won.....

Then I guess it wasn't a stock car, was it?

People need to make like Volvo and think before they do, much more often.

 

[skylineGTR_guy]

the engine was stock and the only difference was the auto tranny and the shift kit......you know what I meant smart ass......

 

[Josh]

Still not stock. "Shift kit" = modified = not stock.

 

[Duke]

Actually, stock Buick Grand Nationals are faster with ATX than MTX. The constant load from the ATX shift pattern keeps the turbocharger in boost better.

 

[skylineGTR_guy]

thats what I was talking about the GN....my friend has one but I forgot what it was called till duke brought it up....I don't really pay attention to muscle cars......

 

[quicksilver1122]

Thanks.

So does the size of the engine translate to the power of the car somehow?

 

[skylineGTR_guy]

well the bigger the engine the more power....well unless you take into account forced induction and all that stuf then a samller motor can have more power than a bigger one but over all yeah bigger= more power

 

[Josh]

When did Buick Grand Nationals ever have manual transmissions?

yes. the hemi has hemispherical combustion chambers. they were (and are, again) produced by chrysler in the muscle car era, and were the fastest engines because precisely of this desing, wich burned air more efficiently and allowed for a more agressive compression ratio and cam profile. as for the thing in muscle cars being a "blower" ... well... the blower is THE SUPERCHARGER ITSELF. a blower can or cant have a hood scoop on it. no, they are called cowl induction hoods. that is when there is a big bump in the hood's sheetmetal. when there is something that has a HOLE in the front, it is a hood scoop, or the so-called shaker hood. and yeah, those always worked to get more air in the engine. the famous "ram air"... the ones that worked, at least.

the 300 means 300CI (cubic inches). the displacement of the engine affects how the car reacts when you stab the pedal. smaller, it will be more slow. if the engine has a big displacement, the torque and horsepower will be available sooner, because the flow of air and power is less restrictive.

nice thorough response there from cano et al.
hemi engines i believe were better in their days since the design allowed the spark plug head to effectively be in the centre of the cylinder, not just at the top. giving a nicer burn.

as an extra question to the supercharger thing that sticks out of cars, i assume the air doesn't go straight into the engine, it does pass through filters right?

and more displacement (bigger engine size) means more power, however a car with smaller displacement can be made more powerful (than one with higher displacement) through the use of superchargers, turbochargers etc.

i don't want to continue the auto-manual debate here, but one thing is clear, no racing series' that are shown in the UK, touring car, f1, wrc rally etc use auto boxes. manual lets the driver be in the right gear when they apply the power after having slowed down. using an auto box, you always have a little lag waiting for the box to realise the revs are lower and change gears. semi-auto shifting is probably the fastest, but regular manual much more fun. i'd like to see someone provide a credible counter-argument to that...

yeah, a way in wich you can recognize a HEMI is because it has the spark plug wires on the valve covers. by the way, you knew that TOYOTA made a HEMI V8 back in the days??? I read about it in hot rod a few years ago, when they featured a little track T Ford with what appeared to be a red ram dodge HEMI, but it was actually a toyota 250-something V8. it looked cool... not too powerfull, but lookin good indeed.
And you can add those power adders to the big engines too... so they will be just BRUTAL. read about a 57 Mercury Wagon with a twin turbo setup on a 460 ci big block ford that made an staggering 714 lb ft of torque at... get this... 3500 rpm. all of it for under 3000 dollars. wanna try???

yeah!
