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
Motes & Williams Twin Engine Dragster 3
The Motes and Williams car was `70 & `71 NHRA World Champion in Top Gas. In
1970 it won the Springnationals and World Finals. In 1971 it won the
Springnationals and U.S. Nationals.I hope you enjoy my current Motes &
Williams footage. This was taken Oct 2001, Mike Newkirk at the wheel. RC
Williams and Greg Cook starting the car and me, I'm behind the camera. I
don't remember, but this was one of the first times the car ran since we
restored it. Wish I had my camera with me at John Laubhan's shop during the
Jalopy Showdown Drags 2010 - Twin-engine Dragster smoke-run.
Front engine, TWIN-engine dragster that was at the Jalopy Showdown Drags
2010. This was filmed at Beaver Springs Dragway. I had previously seen this
car at the Wheels of Time show in Macungie PA in August. The car has two
392 supercharged HEMI engines. The smoke pass is almost required, not only
because of the tires not being able to hold the power, but because it would
surely break the drive train if it actually hooked!
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.

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

Top Fuel Nitro Motorcycle Import vs Harley - Larry "Spiderman" Mcbride 5.83et @ 232mph
Dragbike Live was on location at the Manufacturers Cup Finals held November
12-14 2010 at South Georgia Motorsports Park in Georgia when Top Fuel Nitro
motorcycle legendary drag racer Larry "Spiderman" Mcbride against V-Twin
Top Fuel Harley rider Tommy Grimes aboard the Ray Price Top Fuel Nitro
entry met in the final round. Mcbride ran an incredible 5.830 elapsed time
at 232.75 miles per hour for the win! This was a historic final
round,marking the first time a V-Twin Top Fuel Nitro burner would face off
against an import Top Fuel Nitro Methane injected drag bike.
World smallest V12 engine
Apparently the builder's name is Yesus Wilder and he only used three
materials to build the engine. Stainless steel, aluminum, and bronze.
All credits to him.
