180 degrees in the engine bay, and 90 degrees outside, you will experience about a 12.5 percent change in horsepower. \u00a0This boils down to taking an engine with 300 horsepower down to only 265 horsepower.<\/p>\n<p>The combination of a restriction of air and a hot air cleaner can make this situation worse. \u00a0There are kits made that use window washing injectors to cool intake charges, but most drag cars use a snorkel setup that goes out of the engine bay to get closer to incoming air.<\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_19776\"
