Scale Model Running Challenger Flathead V8 By Ron Colonna
Bore: 1 in.
Stroke: 1 in.
Displacement: 100 cc
Max RPM: 6,000
This engine was built early in my gasoline engine building career. I
received the castings and drawings as a Christmas gift from my wife. I had
it running about five months later. This is the engine that creates the
most interest at the shows. So much so that I've had to rebuild it twice
because of wear. As designed, it had some major shortcomings. The conrods
were bronze castings which promptly wore grooves in the crank. These were
replaced with rods machined from 2024 aluminum. Pistons were remade and the
engine fitted with rings made from the George Trimble method. Oil control
rings are a necessity as the engine smokes badly without them. An electric
start system was added and the engine now runs with the push of a button.

Dyno. The motor is a
4.9L flat 12 which has been upgraded with EFI via a Bigstuff3 PRO SEFI ECM
and twin Precision turboturbochargers. At this stage the motor is running
6psi Boost and has no internal
modifications. We ran it from 3500rpm to 7500rpm and it produced 650hp and
600lbs*ft of torque. Enjoy!
Also I just posted a new video on my channel showing a walk around of the
car with some of the new wheels and brakes mocked up on it. If you guys are
interested check it out there.
