Our header coating also helps lower under-hood temperatures, keeping intake air cooler.” Our dyno showed 260.9 peak hp at 5,380 rpm and peak torque output of 277.7 at 4,690 rpm after the installation. That is a gain of 14.7 peak hp and 27.6 lb-ft of peak torque.
How much HP do you gain with long tube headers?
It depends on the style, length and size of the headers as well as the size and modifications done to the engine. Generally speaking a set of long tube headers on an American V8 can yield 20 to 30 HP without other modifications on vehicles with a stock exhaust system. Also headers generally require ECU retuning.
Do long tube headers add power?
Long tube headers provide horsepower on higher RPM scale, whereas short tube headers on lower RPM scale. Long tube headers work the best at the peak of the RPM scale. This installation approach is perfect for cars that rely on lower RPM power (like daily driver) and even better for a turbo boosted engine.Jul 1, 2021
Can headers increase horsepower?
In general, a quality set of headers should provide an increase of approximately 10-20 horsepower, and if you're restrained with your right foot, you may even see an increase in fuel mileage.
What do high performance headers do?
While it may not make a drastic difference such as installing a turbo or supercharger, investing in high-performance headers can increase the engine's torque, and subsequently the car's horsepower. Depending on the type of car you have and exhaust system, upgrading the headers can result in a 5% increase in horsepower.
