Are water-cooled turbos better?
What does water-cooling really do? Water-cooling improves mechanical durability and lengthens the turbocharger’s life. Many turbochargers are designed without water cooling ports and are sufficiently cooled by air and the lubricating oil that flows through them.
Are turbos coolant cooled?
Liquid cooling improves mechanical durability and extends the life of a turbocharger. Many turbochargers are designed to be sufficiently cooled by air. Other turbochargers are specifically designed and have built-in ports. Consequently, coolant and/or oil can be pumped through the main body.
When did VW start using water-cooled engines?
The Volkswagen K70 arrived on the scene in 1970 and it marked the dawn of the front engined, watercooled VW. (Although its engine was an evolution of an NSU motor, and a bit of an anomoly in this story.)
Does engine oil cool the turbo?
When the engine is running, the oil is a coolant that draws heat out of the turbocharger. But, for the oil to cool the turbo, it must flow. Restrictions in the oil feed or return lines can cause the turbocharger to operate hotter than normal.
Why does exhaust cool water?
A water cooled boat exhaust muffles engine noise. By injecting cooling water into the exhaust pipe, the noise quietens. The water is transported from the water-cooled inboard engines and then pushed out of the exhaust pipe by the exhaust.
How long does a turbo take to cool down?
Idling the engine cools the turbo because it circulates the oil, yet does not make the turbo “work.” The amount of cooling it needs is directly related to the way you just finished driving it. When you drive it gently around town, 15 seconds should be more than adequate.
How do you cool down a turbo?
Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo.
What is a Type 1 VW engine?
Type 1 “Upright” Engine: Sizes 36HP, 40 HP, 1300cc, 1500cc (single port), 1600cc (single port), 1500cc (dual port), 1600cc (dual port) 1500cc and 1600cc Type 1 engines switched to dual port intakes in 1971.
How do I keep my turbo Cool?
Let the Engine Cool After Driving After driving, get in the habit of leaving the engine running for a couple of minutes at idle, which will cool the turbo enough to switch off the engine without cooking the engine oil.
