Thanks Pete! Now I know.Hemi Pete said:Not a stupid question: you "haveta" learn from somewhere, right? Pinging is the metallic noise you hear when the combustion chamber becomes too hot under load.
The result is that around the time the spark plug fires the air/fuel charge, the hot metal or bit of carbon will set off another flame front from the other side of the chamber.
A metallic "pinging" noise is created when the two flamefronts collide.

How can a cooler thermostat increase horsepower? Well its relatively simple if you learn this simple formula. For every 5 degrees you drop your air intake temperature you increase your horsepower by 1 percent. Keep this formula in the back of your mind while I explain this. As everyone surely knows there is coolant circulation through your lower intake on fuel injected engines and the intake on carbureted engines. Normally this coolant has to warm up to a temperature of between 192 and 196 degrees or so before it is allowed to circulate through the radiator where it can dissipate some of the engine heat. So what does this hot coolant do to the intake, well it heats it up of course. The thermostat can only control minimum engine temperature and does not affect maximum temperature so keep this in mind. So in essence it will make the minimum intake temperature on a warmed up engine around 192-196 degrees with some leeway on either side depending on engine and cooling system design. Well lets say we put a 180 degree thermostat in there, well that's 12 to 16 degrees cooler than the stock thermostat. If you could maintain that 180 degrees constantly that could possibly drop you air intake temperature around 12 degrees or so. What does this mean to power output, well on a 200 hp engine that comes out to around 5 horsepower for basically 4 bucks. But in order to take advantage of this your engine must be capable of maintaining this 180 degree, this is normally accomplished through high flow thermostats, auxiliary electric fans, running a high water content in the coolant, etc. But this isn't without its drawbacks. the major drawback is a loss in gas mileage due to the internal combustion engine losing efficiency at lower temperatures and that denser air charges also require more fuel to maintain the proper air fuel ratio. So many people may be asking the question why not run a 160 thermostat. Well my answer to this question is that yes you will probably make a little more power with a 160, but it comes at the cost of terrible gas mileage, increased engine wear due to the lack of part expansion which is calculated in to the engine design to take up certain clearances, increased particulate matter in the oil due to less efficient combustion and much richer mixtures. This is why I don't recommend these in anything besides competition use only engines.
