Hi.

Anyone try any electric actuator for wastegate of turbo?

Intead of a boost controller solenoid, using a electric motor to drive a flapper of the turbo with internal wastegate like borgwarner efr séries.

Any cons?

It should be more precise and faster than tradicional actuators and directly plugged to ecu

With a turbo speed sensor it should be perfect!

What do you think?

My Jeep Diesel has an electronic actuator on a VGT turbo (so no wastegate). It seems to work well, but it did fail... And it's SIGNIFICANTLY more money than a good 2-port actuator.

The thing is that with a electronic actuator is more precise.
But if the reliability is not good maybe is better not to think about it

Maybe go for a 2 port actuator.

I have a 4 Port boost control solenoide

By the way I'm trying to fit a borgwarner 8374 iwg in the same location as yours

Don't some street cars come with an electric wastegate actuator. A quick google found one from a 2011 Kia for under $220.

Mahle says about theirs: "The electrical actuator can reach any desired wastegate position in a flash, regardless of the negative or positive system pressure. Its high clamping force ensures minimal leakage and consequently rapid boost pressure build-up. The result is very spontaneous responsiveness. Another advantage of the electrical actuator is the ability to open the wastegate completely."

Yup, electric actuators are common now. Like the Honda Civic turbo has them. You can do things like leave the wastegate flapper open on cold-start to help light-off the cat faster.

The why are aftermarket setups fooling around with 4-port boost controllers when things can be quickly and accurately controlled? Don't both use a similar PWM input?

That's a good point.

That's why I'm thinking of getting one of these instead a 4 Port solenoide and a 2 port actuator.
With a turbo speed sensor like mine it would be the ultimate boost Control
