Rev up your engines!
It's time for the Scotty Kilmer Channel
this is a special episode of the Scotty Kilmer channel in honor of the late great Carroll
Shelby, if you think Carroll Shelby just made great cars in the 60s, you should
see the last car that he was involved in, this 2013 Shelby Cobra as Carroll recently
passed away, this 2013 production Cobra is the last production car that Carroll
had personal involvement in and all I've got to say is, what a way to go, I just
hope I leave something as interesting as this behind when it's time for me to go
now the first thing you're going to notice in this car is that there's no grill
there's just a hole in the front of the car, but as everything else in this car
there's a reason for that, we'll take a look inside to find out why, this engine
puts out six hundred and sixty-four horsepower, it takes a lot of air to make
that much horsepower, and a grill as small as it may be, is going to block some of that
air so it doesn't have a grill and if we look inside the grill we'll see even
more reasons that it's open, there's all kinds of coolers in here that air has to
get through to cool, because air is being used to burn the gasoline to make a
horsepower, but it also has to be used to cool the engine oil and the coolant and
the radiator, so the engine doesn't overheat, so in this case form meets
function and anyways I like the way it looks, now to help make all this
horsepower, there's a twin screw eaton supercharger to supercharged air into
the engine and you'll notice it's has a really small pulley on the top, but under
the engine there's a real big pulley driving it, which of course makes the
supercharger spinning faster with a smaller pulley, so it puts out even more
horsepower and in the case of the Shelby, it puts out 15 pounds of boost that's a
lot and what it's boosting is also impressive as can be
it's a 5.8 liter engine made just for the Shelby, now if you're an old-timer
like me, that doesn't mean anything we like cubic inches so it's like a 351
Windsor that they used to make in the 60s, but although
this engine has the same cubic inch displacement it's a radically different
engine, it's got aluminum heads and it also has an aluminum block that's rather
interesting, the aluminum block isn't sleeved down with cast-iron cylinders or
anything, it uses a Ford process called plasma spray borer, it's a special
process where iron is coated on the inside of the block, so the cylinders can
go up and down and not wear out on the soft aluminum, this process allowed the
original 5.2 liter block to be bored out to 5.8, which you couldn't have done with
cast iron liners, there's not enough room and as you can imagine the engineers had
a field day building this baby, but still it's not considered a gas hog because if
you drive at 60 miles an hour in sixth gear it will run 24 miles a gallon on
the highway and that may be the most amazing feat of them all, given a car
that's got 664 horsepower, but can get 24 miles a gallon on a highway but of
course if you drive it at its full speed which is over 200 miles an hour, you will
run out of gas in about 13 minutes due to the extremely high frictions at 200
miles an hour and all the force that it requires to propel a vehicle that fast
and yes it does go over 200 miles an hour, there are plenty of long straight
highways here in Texas and I just had to find out, so Carroll if you're out there
listening, you did a bang-up job on your last try, and remember if you've got any
car questions just visit the Scotty Kilmer channel and I'll answer them as soon
as I'm done having a little fun!
