Is it possible to tune a turbo to spool up later to have the benefits of better gs mileage and higher end power/torque (for passing etc).

 

I'd imagine that all that would be needed is an electronic boost controller set to constantly keep the wastegate open below a certain RPM.

Not sure how it would all work in practical application though. That may have some weird effects on the power delivery.

 

That's not how you'll get better mpg😀. That's a big part of Internet lore, unfortunately.

 

Show me an OEM car that uses an oversized turbo to get better gas mileage. They tend to use super tiny turbos that will be moving lots of air even without you getting positive pressure in the intake manifold. Its decreasing pumping losses.

Size the turbo appropriately and use you ******* foot to control how much fuel you burn. If you cant manage to keep it out of boost then you are the problem. By intentionally making it spool slower you are just tricking yourself into accelerating more slowly, or youre just gong to have to give it more throttle/more rpm to accelerate the way youre used to. The latter will hurt your fuel economy.

 

Ah.... Reasoning. Using the Foot and Brain. thank you Full Tilt. Thank you very much.
