Rat Rod Engine Dyno Testing - Zoomies!
Want a low buck Hot Rod engine that's not a total pooch and looks "Rat"
cool? David Freiburger from Hot Rod Magazine built this ultra cheap SBC
and runs it on the engine Dyno with multiple intake and Exhaust configurations. He even slaps a
set of Zoomies on it for extra cool factor. What do you think the horsepower numbers will
be? Watch the video to find out and get the June 2011 issue of Hot Rod
Magazine to read the feature story and get all the gory details.
Home made 4-cam hemi fire up #2
This fire up was to test the clutch. The idea is that you set the clutch to
slip at a certain RPM, not only so it will not spin the tires at the hit,
but so you can control the car to get it into reverse after the burn out
and stage the car. You want to have just enough drag to where if your hand
is off the brake the car will creep, but not so much that the brakes won't
hold the car. You also want to be able to bring the RPMs to the point where
the motor runs clean so when you hit it the motor picks right up instantly
rather than having to catch up with the volume of fuel you're dumping in
there; or worse, gag and die on the line because you're dumping more fuel
in than it's ready to handle.
Tommy was told to set it up so it will launch at 3000 rpm, so that's what I
was zinging it up to in this video. It's kinda eerie. The car starts
shaking and really changing tune. You can see Tommy come over and depress
the clutch pedal, lock it, and then try to get the clutch to slip by using
the handbrake... which if you notice, the tires aren't slowing down and
smoke is just pouring out of the brakes.
We also found on this run that the tach in the car is off by 100%. I was
twisting it at 3000 according to the temporary tach in the seat, and the
one on the control panel was bouncing around 6000. No wonder we hurt the
motor last time out at the track. Tommy launched it at what he thought was
2500 RPM and it was obviously more like 1250, so that explains why the
motor hydraulicked and hurt the bottom end.
Back to the drawing board. We made some adjustments to the clutch and tried
it again with much better results. but a 3000 launch rpm just seems awfully
He ended up making a few phone calls and the Skuza's told him to set it up
to launch at 2200 RPM. Much better on my nerves at least! I can't imagine
having to do this on a 90% load of nitro... I'd better have my life
insurance paid up. So we'll try it again tomorrow.
BTW- the truck tires on the back are just to be able to get it to fit into
the trailer, obviously when we're at the track we have full size slicks on
*** FUNNY *** Standing next to a 10,000 + Horsepower Nitro burning Top Fuel Hemi engine
*BEFORE COMMENTING* on actually how much horsepower is being made,
Check out my other video titled " 10,000 + horsepower from a modern Top
Fuel HEMI ! " Let Mike Dunn & Gary Gerold explain the facts to you first.
Standing next to a 10,000 + horsepower Top Fuel Hemi
engine. Everyone has to atleast once in thier lifetime!
Ahhh... The sights, smells and sounds of a Nitro Methane burning monster
Top Fuel Hemi engine. An exprience one doesn't soon forget. An experience
that can't properly be captured on a video. A sensation that'll leave you
in awe and always coming back for more!
*Old Info 2006* Drag racing is one of the most popular forms of motor sport
in this country. Hopped-up Hemis and blown big blocks shred tires and
thunder down the 1320 in no time flat. But even the quickest modified
street cars pale in comparison to the awesome power of Top Fuel Dragsters
& Funny Cars. In fact, the forces at work inside these cars are almost
unimaginable. Here are some specifics that really put top fuel power and
acceleration into perspective.
One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4
rows at the Daytona 500.
Under full throttle, a dragster engine consumes 1½ gallons of nitromethane
per second; a fully loaded 747 consumes jet fuel at the same rate with 25%
less energy being produced.
A stock Dodge Hemi V8 engine cannot produce enough power to drive the
With 3000 CFM of air being rammed in by the Supercharger on overdrive, the fuel mixture is
compressed into a near solid form before ignition. Cylinders run on the
verge of hydraulic lock at full throttle.
At the stoichiometric 1.7:1 air/fuel mixture for nitromethane the flame
front temperature measures 7050 degrees F.
Nitromethane burns yellow. The spectacular white flame seen above the
stacks at night is raw burning hydrogen, dissociated from atmospheric water
vapor by the searing Exhaust gases.
Dual magnetos supply 44 amps to each spark plug. This is the output of an
arc welder in each cylinder.
Spark plug electrodes are totally consumed during a pass. After 1/2 way,
the engine is dieseling from compression plus the glow of Exhaust valves at 1400 degrees F. The engine can
only be shut down by cutting the fuel flow.
If spark momentarily fails early in the run, unburned nitro builds up in
the affected cylinders and then explodes with sufficient force to blow
cylinder heads off the block in pieces or split the block in half.
In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at an
average of over 4G's. In order to reach 200 mph well before half-track, the
launch acceleration approaches 8G's. * Dragsters reach over 300 miles per
hour before you have completed reading this sentence.
Top Fuel Engines turn approximately 540 revolutions from light to light!
Including the burnout the engine must only survive 900 revolutions under
load. The redline is actually quite high at 9500 rpm.
The Bottom Line; Assuming all the equipment is paid off, the crew worked
for free, and for once NOTHING BLOWS UP, each run costs an estimated US
$1,000.00 per second. Putting all of this into perspective: You are driving
the average $140,000 Lingenfelter "twin-turbo" powered Corvette Z06. Over a mile up the
road, a Top Fuel dragster is staged and ready to launch down a quarter mile
strip as you pass.
You have the advantage of a flying start. You run the 'Vette hard up
through the gears and blast across the starting line and past the dragster
at an honest 200 mph.The 'tree' goes green for both of you at that moment.
The dragster launches and starts after you. You keep your foot down hard,
but you hear an incredibly brutal whine that sears your eardrums and within
3 seconds the dragster catches and passes you. He beats you to the finish
line, a quarter mile away from where you just passed him.
Think about it; from a standing start, the dragster had spotted you 200 mph
and not only caught, but nearly blasted you off the road when he passed you
within a mere 1320 foot long race course. That, folks is acceleration!
First Firing of 540ci Dragster Engine on Methanol !
First firing of the new engine in the dragster. This is unbelievably loud!
..1700 BHP from a Supercharged 8.8 Litre (540cu) Running on Methanol ...
This is a beast! The movie can't show just how loud this really is!

Awesome V12 Monster diesel engine Awake and Alive startup
Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.
