How To Eliminate Turbo Lag – Volvo’s Easy Fix!

Turbochargers provides lots of horsepower, but they also have turbo lag, so it takes time for the turbo to spool up and provide boost, delaying that power delivery. To combat this, Volvo came up with a very clever solution. The process starts with an air compressor, which fills up a high pressure air tank. If you floor it, asking for full power, the air tank releases that high pressure air directly into the exhaust manifold, where it then rapidly spools up the turbo. This means you don’t have to wait for the exhaust gases to do the work, like you would with a traditional turbo engine. Once your engine starts making good power, the exhaust gases take over to maintain boost, so the air compressor can go back to work filling up the air tank, ready for the next full throttle deployment. So you have a compressor (air compressor), for a compressor (turbo), for a compressor (engine). Neat!
