Turbo finally on its way out?

[ADV_93]

Engines have improved thermal efficiency with boost... As a general rule, the increase in pumping losses is vastly outweighed by the thermal efficiency increases of higher boost levels.

For example - my car with K14, used to do about 45mpg on the motorway, making about 2-3psi boost... Changed that for the GT2052V and instantly jumped to about 65mpg with 9-10psi boost on the motorway... Long as you're keeping charge temperatures down, you'll be gaining improved efficiency from higher boost.

If you think you consume more fuel when the boost is up, you're living in the land of petrol.

Guess i learn something new every day.
