Default Nitro engine temp?

How critical is engine temperature to optimum performance on any nitro engine? What should the temp be for an OS 12 on a hot summer day with ambient temp about 90 degrees?

Hey atr4tigers

I never run any of my Motors over 210... Period... Other than when Breaking them in(Novarossi motors ONLY)Then its 220... But Only for Break-In with the Newer Novarossi motors... They're REALLY TIGHT A$$ed... But Always Use a Heat Gun to Warm the Head-Up First!!! A lot of guys run there motors at 220, but then they're always Rebuilding them after about 5-7 Gallons of Fuel. At 210 I get at least 10 Gallons Plus with all my Motors, and those other guys I see running at 220 Don't seem to Pull me on the Back or Front Straights.


Have a Good One!!!

Brad

I think a little too much is made of engine temperature. Most people will tell you that a .12 engine should run in the 230F-250F range.

You ask a good questions because outside temperatures and humidity play a large role in engine performance and temperature. Another factor is the glow plug that you are using (ie. #5 or #6 will be hotter than #7). Also gearing can be a factor (ie, short techinical tracks requiring torque vs. large open tracks requiring more top end)

All in all you will most likely see average to good performance from your engine when temperatures reach 230F-250F (assuming clutch and two speeds are set properly). However, I would recommend using the temperature only as a reference. If your engine is running 270F and it does not stall, lean bog and is still blowing smoke....let it rip. Tunning to temperature will most likley leave you frustrated and under powered.

Tuning for temp is merely a guide. Otherwise tune for power , then richen it a little from that point and you should be good.

Watch the smoke , listen to the motor , watch the power. The more you work at it the better youll get to understand what adjustment the motor needs.
