Variable twin-scroll turbos seem to be the answer as they have a split valve that allows exhaust gases to flow to different scrolls giving you the best of a small and larger turbo. Larger turbos take longer to spool up but can provide a much higher boost and more HP. Smaller turbos spin much up sooner and provide an added boost at lower RPM. Nowadays, turbos come in many sizes to fit any application. Namely, Porsche 911 turbos had a nasty reputation of turbo boost coming on very quickly and causing the driver to lose control. Turbos and the types of turbos have come a long way from the stories from when turbos used to come ‘on’ very suddenly and unsettle the car. Many car enthusiasts have heard lots of arguments against using turbos because of turbo lag and assume that this issue still plagues most turbos to this day. It’s very simple, simply plug in your current HP and the amount of boost you plan on using, and voila! You have your horsepower estimate.Īs we explained previously turbo lag is merely the time it takes from when you press the accelerator for exhaust gases to build enough pressure for the exhaust turbine to spin and create enough boost to start forcing air back into the intake. The formula is very simple and I have put together an easy FindCarStuff Turbo Calculator so you can find out how much POWER you can squeeze out your next engine build with a turbo or supercharger. The Formula: Turbo Output = Starting HP x ((PSI/14.7)+1) How much HP does a turbo add? Turbo charger on car engine This infusion of pressurized air is boosted and causes more air to be shoved into the engine creating more POWER. A turbo uses the engine’s exhaust gases to spin a small turbine that is attached to an intake turbine that draws in air, passes it through an intercooler, and forces this cooler, pressurized, denser air into the intake. We will explain what turbo lag is in detail and how some manufacturers are finding solutions for this issue.Ī turbo is technically a supercharger it just goes about forcing air differently than a supercharger. Turbo lag is simply the time it takes the turbo spooler to start to force a significant amount of air into the intake. This is where superchargers are superior to turbos as they don’t experience turbo lag. The advantage of the supercharger over a turbo is that the compressor is attached to the engine so the compressed air supercharges the air at much lower RPM’s which gives the engine more horsepower and torque at lower speeds. But, because it uses the motor to spin the compressor it does draw some power from the engine but the gain in horsepower is still significant. This added compressed air makes more horsepower. Let us explain.Ī supercharger is typically a belt-driven air compressor that uses the engine’s power to spin the compressor to force more compressed air into the air intake manifold. You’ve probably have heard of superchargers and turbos but, which one is better? How are they different? They’ll both deliver more horsepower but they deliver the power differently and work differently. This allowed them to increase horsepower from 1,750 hp to 2,500 hp. To resolve this issue Buchi scavenged the exhaust gases of the engine to propel a small turbine compressor mounted the same shaft. In fact, at such high altitudes, the engine can lose half of its horsepower. Buchi was working on resolving an aeronautical issue when airplanes reach high altitudes the lack of air pressure and oxygen effectively starved conventional engines. Turbochargers didn’t come about until 1905 by German engineer Alfred Buchi. Gottlieb Daimler (of Mercedes Daimler) perfected the modern gear-driven supercharger as we know it today in 1885. Clark’s two-stroke engine was actually a one-cylinder motor with a secondary cylinder that force air into the combustion chamber. The first supercharger was invented in 1878 by Scottish engineer Dugald Clark.
