Anyone ever thought of doing hood vents to help for cooling. I see them on CYAN race team cars. Wonder in Polestar/CYAN or the team has any specs for these.

Two things, one there is no cooling needs that those would help. As we have discussed in other threads, the only cooling issues revolve around the transmission and possibly brakes. Hood vents won't help either. Two, I'm pretty sure those are there for aero and not cooling.

Good to know. Just saw them and wondered is all. I guess i am used to hood vents galore coming from and Evo X 
Evo has his vents/scoops because it can have a TMIC vs our FMIC.Good to know. Just saw them and wondered is all. I guess i am used to hood vents galore coming from and Evo X
Edit: Looks like the Evo's may just use FMIC. My Subaru had a TMIC, hence the scoop. Looks like the difference is where the intakes are. The Volvo's have a larger frontal area to suck air in, so really have no need for hood scoops. The Evo uses the hood scoops for its intakes it seems. It looks like only the driver's side are actually open while the passenger side is sealed.

They are for cooling, and may help reduce drag a bit as well, but probably not by much if any. As the air passes through the radiator it needs somewhere to go. An easier exit through the engine bay means more air can pass through the front end to help cool whatever fluids are passing through the various radiators there may be (engine coolant, engine oil, tranny oil, etc.). There are quite a few performance cars on the market now that have either hood vents, vents behind the front wheels, or both for this very reason. Managing heat is one of the biggest challenges for race cars. But as P50GT said, engine coolant temps really aren't the issue with the P*. If you put a tranny cooler and/or oil cooler behind the front grill these could help. Folks with the d088 intercooler could see some benefit as well since it sits in front of the radiator, but it would probably be negligible.
This is what the Evo forum said about the Evo X vents/scoop: "The one near the winshield cools the turbo. the two in the front release heat just like the old evo. the side ones behind the front tires also release hot air from the engine bay. they are all functional."
Volvo’s original skid plate has the louvre that directs airflow upwards towards the exhaust manifold & turbo compressor housing.
Many people don’t know that removing the skid plate actually reduces the amount of air that gets forced through the intercooler/radiator/condenser.

Here are some successful approaches to reduce heat build up in the T-6: To improve air flow through the engine bay remove the rubber rain "dam" at the front of the windshield cowl. It just pops off. Replace the OEM radiator with the do88 high capacity unit. Add a transmission cooler. Wrap your DP in rockwool tape. @lcfpolestar
