Oil grade for a Turbo 172 track car

[clio_cup]

Got my first track day coming up since the engine has been boosted. Currently running a good grade of 5w40 and has an oil cooler fitted. Would this be alright or be beefed off running a 50?

Cheers all

What’s the hot oil pressure at idle and under load? That’s the best way to answer if you’re better off upping the oil grade.
