Why does my turbo kick in late?
WHAT CAUSES TURBO LAG? Turbo lag is caused by low engine speeds. Basically, when the car is coasting or power is not being applied, there are not enough exhaust gases to spool the turbine/s.
Does a turbo spin all the time?
Simple answer is yes. Turbos work at idle and at a predetermined rpm, they produce enough air flow to overcome the vacuum of the engine, thus producing ‘boost’. This is usually referd to as spooling up the turbo. A turbo is an addition to automobiles to increase the horsepower of the engine.
Do turbos work better cold weather?
As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
How can I make my turbo more responsive?
Aftermarket units are more responsive, allowing your turbo to pressurize the intake tract more efficiently. Purchase a new intercooler kit for your turbo vehicle. The intercooler system is what most thoroughly affects turbo response.
What’s the RPM limit on a turbo charged car?
While engines usually have an rpm limit of 5,000 – 7,000 rpm, turbos spin at up to 150,000 rpm! In turbo-charged cars without intercoolers, temperatures can shoot over 150 degrees C. Did you know that inertia keeps the turbo spinning even after you switch the engine off? A hot shutdown is one of the top reasons behind turbocharger failure.
How often should you idle your car with a turbo?
With time, the turbo will become less effective. Take care of your turbo so that it gives your engine adequate boost and thus, an enjoyable driving experience for years to come. Let the car idle for 30 (minimum) – 60 (maximum) seconds before you drive off.
What causes a turbo to fail after a hard run?
There’s also the issue of heat soak from exhaust gas. The worst thing you can do to your turbo is switch the engine off immediately after a hard run. “The number one cause of turbo failure is oil “coking”.
Are there dump valves in a turbo diesel?
I think not, but I’m not sure. Turbo Diesels don’t have Dump Valves like Petrol. They have recirculating valves that force the unused air back into the system, they do have a waste gate so if the Turbo is being fed more air than needed it will divert through the waste gate.
