Reccomended Engine Break In
Remember to always run your Go Engine in a well ventilated space and also remember model engines and model
fuel are not toys and should not be treated as such.
The Following steps are what is reccomended for a proper engine break in. A proper engine break in will
not only increase the performance of the engine it will also greatly increase the longevity of your Go Tech engine.
During the break in period the engine is under the most stress. Because of the tight tolerances of the piston and sleeve (which
is vital to a performance engine) the connecting rod will see the most abuse during break in. To minimize this abuse it is
important to keep the engine running in its optimal temperature range, running too cold is especially hard on the connecting
rod. The ideal temperature for break in is between 210-240 degrees, we recommend purchasing a temperature gun and keeping
a close watch on the temperature during break in.
The following break in procedure will require 7 to 8 tanks of fuel. We recomend that you use a fuel with
a high oil content and low nitro content such as sport model fuel and not racing fuel. Always allow the engine to cool down
to ambient temperature inbetween each step before continuing to the next step. Always place the piston in Bottom Dead Center
before it has a chance to cool, you will need to do this everytime you use your engine. If you follow these steps you should
have a long lasting engine.
- The first step is to wrap the engines cooling head up in aluminum foil. this will help it achieve optimal
tempature fast and help insure the engine is not running too cool. It will also force you to run a richer needle setting to
keep the engine in the temperature range. We also reccomend using a heat gun of hair dryer to get the engines temperature
up above 160 degrees before trying to turn over the engine. Allow the engine to cool and remember to place
the engine at bottom dead center
- For the first 2 tanks of fuel you should only let the engine idle (do not rev at all.) make sure the engine
is around 210-240 degrees monitor it closely and use the needle valve to control temperature.
- For the third tank of fuel you should repeat the steps and pulse the throttle to 25%, remember do not
hold it open just slow open then close no more than 25%. If you have a computer radio you can use the servo endpoints to accomplish
this and it will make it much easier for you.
- For the fourth tank of fuel repeat step three but this time you can open the engine up to 50%. You should
no longer need the alumn. foil wrapped around the cooling head and remember to keep a close watch on temperature, at
50% throttle it will be very easy to over heat the engine. Remember to control the temperature with your needle valves.
- Tank five is a repeat of step four but this time open the throttle up 75%. Remember that you want to pulse
the throttle and should never have the throttle open for longer than 1 second.
- Tank six repeat step five but this time open the throttle up 100%. Remember that you want to pulse the
throttle and should never have the throttle open for longer than 1 second. At this stage it is extremely important to watch
temperatures as the engine can over heat very quickly and unexpectedly. In order to maintain temperature at this stage the
engine should be running extremely rich.
- Now your ready to take the car out and tune for performance your engine should be ready to go. Don't overdue
it too much for the next 2 tanks but you should be able to drive around the track at a good speed but not race speed.
Get ready to go out there and win.
