Heat soak - vented hood options that are not "louvered"

I did the radiator, and before next summer ill swap out the fans. At least in TX it seems like you need to do both. If that's not enough its

I did the radiator, and before next summer ill swap out the fans. At least in TX it seems like you need to do both. If that's not enough its time to start cutting into the hood.

Why get fans? Just turn them on at a lower temp right?

Oh of course. I'm just saying in my post that I think the ideal way to improve heat transfer in our cars, and most cars in general is to vent the hood. There's almost no downside - it's weight reduction (hopefully), while allowing massive amounts of heat to vent itself, like Synolimit has experienced. A vented hood will always improve cooling efficiency at the speeds our cars experience.

A larger radiator and fan will help, but like I said - it's more of a "reactionary" solution to the problem, versus a "primary" approach of simply allowing the heat to not form as heat soak and get trapped in the first place. Another factor is also if people are okay with replacing the OEM hood - in that case, a larger rad / fans are required. But for race cars, you won't find one without hood/engine bay venting. ^^

Getting larger fans or more efficient fans will allow more airflow, which in most cases for cars, is beneficial. The OEM Radiator/Fan combination for some people simply cannot keep the car cool at full tilt, and that is where I'm assuming people are having issues, esp. with turbos.

Uprev adjusts the temp they turn on. The GTM fans move a lot more air than the stock ones.

Alstann, you're right on the vents being the best way to get hot air out of the engine bay. If there were a vented hood on the market I liked from a functional/aesthetic standpoint I'd start with that. I'm just not a huge fan of the options we have on that front, so I'm going to try adding the fans to the CSF radiator I've got, lowering the fan temperature more and running less antifreeze. If that isn't enough to keep temps stable, then ill start cutting holes.
