You have to do a video of that thing spooling up now!

Good result. Is egt measured before or after the turbo on your installation?

Hi Dougal
The egt is measured just after the turbo.

That makes sense. Your pre-turbo measurement will be around 700-720C at 100km/h with that turbo and that boost on that engine.
This is safe, but don't go any higher. You can move the probe to the manifold to know what it's actually doing. But the lack of piston-squirters on the non turbo engines are the main reason to keep it conservative.

You should have around 110kw at the crank.

Hi Dougal,

110kw at the crank is what the installer suggested. Unfortunately I didn't get a Nm reading the Dyno was configured for Lb not ftlb. The reading was about 800lb.
Brad suggested 600 deg was safe. This is what I was looking for, improved performance without destroying my engine.
Thanks for your input.
