Turbo is red due to exhaust gases pooring through it at a great rate.

Normally this is only visable if it is poor light.

That's why you never wash a hot engine as it would crack.

You are recommended with a turbo to drive gently for the last couple of minutes to let it spin down and cool, otherwise you shorten it's life.

so if i inrease boost like i did before the whole turbo glowed red that cant be normal

[lonky]

Does sound if you are over boosting, which can cause a whole load of problems.

I presume you understand how a turbo works and what the waste gate is used for. If not I will explain

You're definately overboosting that turbo, check all the vacuum pipes are connected and in good order with no splits or colapsing under vacuum. Also check the waste gate maybe jammed shut.
