Default Will the turbo glow red without load?

If you put the car in neutral and rev the engine hard for a while, will the turbo glow red or this will happen only with load?<ul><li><a href="http://youtube.com/watch?v=MsQipOFAP7M">http://youtube.com/watch?v=MsQipOFAP7M</a</li></ul>

Default no, it has to have a load

your turbo won't spool unless in gear, in audis at least

the wastegate is open when in neutral

so no, it wont glow

but go drive around hard for a few minutes, flooring it a few times, then stop, leave the car on and go look at the turbo, it will still be glowing
