How does Volvo eliminate turbo lag?
Volvo has something called ‘PowerPulse’ to prevent a turbo lag. The patented system is present in Volvo’s D5 Diesel engine having two sequential turbos. It employs compressed air to spool (process of unloading the air from a turbo at high pressure) the turbo within no time.
How do you know when your turbo is going bad?
If you notice that your car isn’t accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing. Similarly, a turbocharged car that struggles to maintain high speeds or isn’t able to reach speeds it once could may be experiencing turbo failure.

How do you reduce turbo lag?
How to Reduce Turbo Lag
- Replace your turbo vehicle’s exhaust downpipe with a smaller-diameter unit. A downpipe with a smaller inner diameter offers less airflow, slightly reducing top-end horsepower.
- Replace your stock blow-off valve with an aftermarket unit.
- Purchase a new intercooler kit for your turbo vehicle.

The effect on the turbo is two fold: One, it runs much cooler – doesn’t glow red or anything (the exhaust manifold might (read: does…), though – but that’s a different story). Aside from that, the water keeps recirculating even after the engine is switched off, due to convection (i.e. hot water rises).
When did Volvo stop making the 760 Turbo?
Volvo made few changes for 1990, but in 1991 things got complicated as the 760 line was given a mild face-lift and renamed the 940.

What causes a Volvo engine to spin fast?
Simple. In the first few seconds after starting (even after the oil warning light is off!) the oil pressure is lower, and fresh oil may not have reached the turbo yet – and if you race the engine, the turbo will spin fast with insufficient oiling of the bearing – not good.
