This is one of the more popular misconceptions. A wastegate is possibly the only component in your whole engine package that can actually be made smaller as you increase your boost/horsepower output. Use this simple guide: Big Turbo/Low Boost = Bigger WastegateBig Turbo/High Boost = Smaller WastegateSmall Turbo/High Boost = Smaller WastegateSmall Turbo/Low Boost = Bigger WastegateWastegates don’t operate in high temperatures.False. Contrary to the popular belief, external wastegates are usually mounted at the hottest part of the exhaust. It’s the place where all the exhaust gases meet, creating extra heat. This, combined with the late combustion of unburnt fuel (due to rich mixtures, retarded timing and high octane fuels) significantly raises the exhaust temperature.Larger wastegate valve diameter = better flow.True – sort of. While the valve diameter is without a doubt an important part of the flow rate, equally important, but often misunderstood, is the importance of the flow path. When comparing wastegates with similar valve size, it is important to have a balanced body/valve/spring combination that is designed to work together to allow for maximum boost control. All Turbosmart wastegates are designed with this in mind.(*article courtesy of Turbosmart) <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/smokin.gif"  class="smilie" loading="lazy" alt=":smokin:" title="Smokin    :smokin:" data-shortname=":smokin:" /></blockquote>
