why do Nitro motors need ten minutes to warm up? they realize its like 110plus degrees outside! and regardless dont they use a heat gun to warm em up before they start them? That seem a lil retarded to say we need ten minutes to warm up!
Hear Marcus this may help if u did not all ready know
WEATHER CONDITIONS
It’s a simple fact: for optimum performance, you must retune your nitro engine every time you run it. Anyone who assumes that the needles can be left alone once they have been set is sadly mistaken. An overnight change in weather conditions may prevent an engine from running or may put it at risk of some damage if adjustments aren’t made to the fuel-mixture settings. Ignoring an engine’s tuning needs compromises its ability to make horsepower. In response to certain changes in weather, equipment and other variables, nitro engines must be regularly retuned.
Temperature.
Hot weather requires a leaner mixture setting; cold weather requires a richer setting. Most people assume the opposite because they treat the mixture needle like a thermostat. It is wrong to assume that colder weather requires a leaner setting to keep heat in the engine and vice versa. Cold air is denser than hot air. The denser, colder air packs more oxygen into the engine, so going from hot weather to cold needs a commensurate increase of fuel to balance ratio of fuel-burning oxygen and the fuel itself. The opposite is true in hotter weather. Going from cold to hot weather requires a leaner mixture setting.
Humidity.
Humidity is the amount of moisture (water vapor) in the air. Moisture in the air takes up volume that would otherwise be occupied by fuel-burning oxygen. Less oxygen means less fuel is required to maintain a proper ratio of air and fuel. High humidity requires a leaner mixture setting than dry conditions.
Barometric pressure.
A barometer measures the atmospheric pressure (generally listed in the local newspaper or on the local weather forecast on TV). Higher barometric pressure readings mean more air is getting into the engine, requiring a richer mixture setting to balance the air/fuel ratio.

I thought the nitro guys needed the time for warm ups, just to piss off the electric guys, they are the only ones that bitch about it! lol

"HE" is the only one that really bitches about it so I figured I give him some pointers.... lol
"we" ( me and the other girls) electric guys dont go to a nitro facility and bitch about anything we just deal with it! and, thats what your supposed to do! I personally hate the smell of it!

please tell me where there has ever been 10 minutes to warm up before a race...it has never been that way at srs...i am speaking from experience...even from the old srs...never has there been a race with a 10 minute warm up...i have nothing against gas, but if you allow them to warm up for 10 minutes...the program would last a very long time...and being that srs is in a residential area, im sure there would be complaints...
