PERFORMANCE ENGINES

OWNERS MANUAL

INTRODUCTION

Congratulations on your purchase of a Dynamite

racing engine. Precisely manufactured and assembled,

your Dynamite engine will provide you with trouble-

free performance if you carefully read and follow

these instructions.

USING THE PROPER EQUIPMENT

FUEL

Using the proper fuel is critical in order to achieve

maximum engine performance, reliability, and longevity.

You must use fuel that is specifically designed for model

car/truck/buggy applications. Never use any type of model

airplane glow fuel! Use of model airplane fuel can damage

your engine and immediately void any warranty.

For general use we recommend using Dynamite Blue

Thunder

™

Race Formula fuel with 20% nitro. This fuel

provides the best combination of power, fuel economy and

engine life. Dynamite Blue Thunder fuels are vigorously

tested, researched and formulated to deliver excellent

power as well as engine protection.

Dynamite Blue Thunder is the only fuel which is 100%

certified for use in Dynamite engines.

CARE AND HANDLING OF FUEL

• Followalldirectionsandwarningsonthefuelbottle.

• Itisveryimportanttokeepfuelcontainerscapped

tightly at all times. Some components in the fuel can

evaporate very quickly or absorb moisture upsetting

the performance qualities of the fuel.

• Neverstoreunusedfuelinthefueldispensingbottle.

quart or gallon fuel bottle.

• Alwaysstorethefuelinacooldrylocation,offof

concrete floors and away from any source of heat,

ignition, flame or combustion.

Warning! Model engine fuel is poisonous

to humans and animals.

Drinking model fuels can cause blindness and death.

Handle with utmost care and respect. Keep model fuels

out of reach of children. Never leave your fuel where a

child could have access to it.

GLOW PLUGS

Aglowplughasbeenincludedandisidealforbreakingin

yournewengine.Infact,duringthebreak-inprocedure,

it is not uncommon to go through one or two glow plugs,

as microscopic bits of metal (from the cylinder/piston

wearing in) bond themselves to the plug element causing

glow plug failure. We recommend Dynamite glow plugs

as the absolute best glow plugs for this engine. Dynamite

glow plugs have been designed to deliver an ideal balance

of performance and longevity.

We recommend the DYN2500 glow plug for engines up

to .15 cu in and the DYN2495 for engines that are .20 cu

inandlarger.Itisagoodideatokeepatleastacoupleof

extra glow plugs in your pit box at all times.

AIR FILTERS

Allmodelcarenginesmustuseaproperlyoiledair

filtertokeepdirtoutoftheengine.Anydirtthatenters

the carburetor can immediately destroy your engine.

We recommend DYN2612 as an excellent choice for a

quality air cleaner for .12 and .15 engines and DYN2614

for .21 and larger engines. Clean and re-oil the air filter

after each hour of running to prevent sucking dirt into

theengine.Ifyouintendtorunyourvehicleinextremely

dusty conditions the air filter should be serviced after

each 1/2 hour.

STARTER BOX AND GLOW IGNITER

Dynamite engines are equipped with either a pull start/

spin start system or may require the use of a starter box.

For spin start engines we recommend the DYN5645

Spin Start Hand Held Starter. While we recommend

using a spin starter or a starter box for the initial starts,

starting the pull start/spin start equipped engine can be

accomplished using the pull starter only as well.

For the starter box version, we recommend using the

DYN5610 Ready-Start Universal starter box in order to

handle the high compression of the Dynamite engine. You

will also need a glow plug igniter (glow driver) to light the

glow plug. Use a high-quality rechargeable glow igniter

such as the Dynamite metered glow driver (DYN1925).

Make sure it is fully charged per the instructions.

PAGE 1
Care and Handling of fuel • Follow all directions and warnings on the fuel bottle. • It is very important to keep fuel containers capped tightly at all times. Some components in the fuel can evaporate very quickly or absorb moisture upsetting the performance qualities of the fuel. • Never store unused fuel in the fuel dispensing bottle. Immediately return fresh unused fuel back into your Performance Engines quart or gallon fuel bottle. • Never mix old fuel with fresh new fuel.
PAGE 2
Engine BREAK-IN Dynamite racing engines are manufactured to exacting tolerances and require a special break-in procedure in order to accomplish the final precise fitting of the internal engine components. It is very important that you follow the break-in procedure as closely as possible in order to achieve the best performance and longest life from your Dynamite engine. Engine break-in will take between one and two hours. Dynamite engines are manufactured with an ABC piston/ sleeve construction.

Small: Develops smooth linear power and is easier to control than a larger insert. Best suited for medium to low traction conditions on small to average size tracks. Also offers the best fuel mileage. Medium: Increased power for high traction, medium to large size tracks with a slight decrease in fuel mileage over the small insert. Large: Offers the most explosive power and acceleration with high-fuel consumption. Used for large and fast high-traction tracks.

Pull start engines: 1. Install the engine into your vehicle. 2. Turn on the radio system. 3. Make sure the throttle trigger on the transmitter is in the idle (neutral) position and the carburetor is in the idle position also. 4. Connect the glow igniter to the engine. 5. Use short quick pulls to start the engine. When using a recoil starter, never pull the rope out its full length. Doing so may cause damage and recoil starter failure.

Tank #5 • Once the engine is running, it is important to keep the temperature of the engine up around 200 to 1. Drive your vehicle on a large, flat, paved surface. Over 215 degrees during break-in. In weather below 45 a 3-second time span gently pull the throttle trigger degrees, the engine will tend to run at lower than to full throttle and back again to idle. Accelerate and recommended temperatures of between 140 to 175 decelerate as smoothly as you can. degrees (at proper break-in mixture settings).
PAGE 7
Tuning the Low-Speed Needle Idle Speed Adjustment The low-speed needle (also referred to as the idle mixture or idle needle) should be set after you’re satisfied with the high-speed needle setting. After achieving the proper operating temperature, make a couple of high-speed passes and then reduce the engine throttle to the idle position. Pinch the fuel line with your fingers close to the carb fuel inlet nipple. If the engine dies immediately, the low-speed needle is set too lean.
PAGE 8
A temperature gauge should only be used as a tuning aid by giving you a relative indication of how your adjustments are affecting the engine and to help prevent you from reaching higher than recommended engine operating temperatures. As you lean the fuel mixture, the engine performance will increase along with the temperature. If you continue to lean the fuel mixture and the temperature increases but the engine performance does not change, then you have exceeded the maximum safe lean setting.
