anyone bypass this?

I'd agree that this is a good idea as unless you're in the Antarctic there's no need to heat the throttle body motor

Whilst I agree with the sentiment the region just downwind of the butterfly valve experiences low pressure drops which can lead to icing even in temperatures above freezing temperature of the ambient air. Given that the throttle body is quite short I am suggesting the amout of heating this does to the ingoing air is quite small.

I was going to post the same thing. Not many people believe this

Not going to make any more power and it's there to stop icing (which can happen at temps as high as 70F).

It depends on a lot of factors (humidity, pressure, etc).

While I knew of the phenomena I didn't realise it could be as high as that.

Isn't it called the venturi effect?

Go ahead and by pass that shit. The multitudes of automotive engineers that design stuff like that have no clue wtf they're doing.

so let me get this straight...

remove the bypass, and get ice in throttle body.

The more ice in the throttle body, the colder the air charge.

The cooler the air charge, the more power.

The more power, the less chance of being smoked by prius.

win.

Obviously jk

Sounds like Joules-Thomson effect to me.

Then you stall out and crash.

Venturi effect is more so the increase in a fluid flow' velocity due to a restriction/decrease in the cross sectional area of the flow.
