What is supercharger lag?

What is supercharger lag?

The “lag” that you are feeling is from the supercharger bypass valve closing and the boost building. It is not from any rpm dependent variables. It’s just the transition of the air pressure. The bypass valve allows air to bypass the rotors which prevents boost.

What does engine lag mean?

The lag comes from the time it takes the engine to create enough exhaust pressure to spin the turbo and pump compressed intake air into the engine and is longest when the engine is in a low-rpm, low-load cruising situation.

How much lag does a supercharger have?

By contrast, a supercharger has no lag; because its air pump is linked directly to the engine’s crankshaft, it’s always spinning and instantly responsive.

What has more lag turbo or supercharger?

No lag: the supercharger’s biggest advantage over a turbocharger is that it does not have any lag. Power delivery is immediate because the supercharger is driven by the engine’s crankshaft.

Does supercharger damage engine?

Assuming a properly tuned system, proper oil change and engine maintenance, and similar driving, supercharging generally will not shorten the life of an engine, just as is the case with OEM turbocharging (with proper cooldown for turbochargers. A cooldown period after driving is not necessary with supercharging).

Can you turbo a supercharger?

Yes. You can Use both. The concept of supercharger and Turbocharger are slightly different. Infact when you go for turbo charging it involves the concept of suercharging indirectly but not the other way round.

Are superchargers bad for your engine?

Superchargers and turbochargers are not bad for your engine. They have been used on engines since engines were originally designed. They offer the advantage of increasing engine performance. Turbochargers can also enhance fuel economy but have more moving parts, which could lead to extra maintenance.

How does a supercharger affect engine response?

By contrast, a supercharger has no lag; because its air pump is linked directly to the engine’s crankshaft, it’s always spinning and instantly responsive. The power boost it provides, and therefore the engine response you feel through the seat of your pants, increases immediately in direct proportion to how far you press the accelerator.

What is turbo lag and why does it matter?

That’s because the turbocharger requires a moment to “spool up” before delivering its burst of additional power—it takes a second for exhaust heat and pressure to increase enough to spin the turbo after you push on the gas pedal. It’s called “boost lag” or “turbo lag” for obvious reasons. A supercharger sits atop the Dodge Challenger Hellcat’s V-8.

Do Electric superchargers work as advertised?

BorgWarner, the unit’s manufacturer, says the electric supercharger “delivers boost on demand until the turbocharger takes over, improving boost at low engine speeds and nearly eliminating turbo lag.” Having driven this engine extensively, we can confirm that it works as advertised.

What are the different types of superchargers?

There are three types of superchargers: Roots, twin-screw and centrifugal. The main difference is how they move air to the intake manifold of the engine. Roots and twin-screw superchargers use different types of meshing lobes, and a centrifugal supercharger uses an impeller, which draws air in.
