BBK intake vs ls6 intake

Coolant running through them would increase posible heat soak as well. Coolant isnt exactly cool, LOL. So a metal intake on a car without coolant running through it should stay cooler as the only heat soak is from engine bay temps & the heads. And engine bay temps will decrease with the car moving and air flowing.

Just run one on dyno and watch the numbers drop as it heats up. Numbers will look good starting off. An hour or more on the dyno and there is a decrease in hp and tq. It's happened with more than one bbk.

I watched one being dynoed and over the course of the tune 2-3 hours, it kept losing hp. At the end of the tune it dropped 13hp from when they first started.
This was tuned by a reputable forum sponsor and they said they've experienced this before with the bbk.
You might not feel a loss or gain of 13hp, but regardless it will heat up over time. The heat soak is not a myth regardless of what anyones opinion is.

I also wanted to add that the tuner said if a bbk equipped car was running in 30 degree temps during the winter months, heat soak wouldn't be as much an issue.
On a hot summer day in july or august, you could expect an even bigger drop off in performance that may not be felt or measured except on a dyno.
He went on to ask how your car runs during a cool 40 degree day, as opposed to a hot and humid 90 degree day. I think we can all agree any performance oriented car runs better in cooler ambient temps.
BTW, they dynoed the bbk car on a 60 degree day, so it was not very hot out and still saw a drop off in numbers over the course of a couple hours.

To each their own but i would much rather have cast than plastic any day plus it can be ported

I don't have s dyno sheet. It wasn't my car. I was just there observing and talking with the tuner about dyno tuning my car. He simply shared the info on what he was currently working on at the time, and his prior experience with tuning cars with bbk intakes.
I'm not here to argue what intake is better orthan aluminum vs composite. I'm just simply stating what I observed and passing on what the tuner told me.
Take if for what it is. I don't really care either way.
