Does the Holley intake really work?

I also think you wasted your money on that 80mm overpriced, overinflated power ratings, piece of **** throttle body. If you noticed no gains with just the TB (No suprise there), then going to the Holley intake (Even if you port the TB opening) will also show little to no gains, as the Holley does not make any more power than the LS6 intake.
Does not sound like very good logic to me that you think you need to buy an intake manifold for $500 in order to see an improvment that a $400 TB didn't make for you on the stock motor.
Good luck.

How about a dyno compare of a ported Holley vs the LS6 on a heads and cam car?
Not being a smartass I just want to know the answer to the question too.

It is not just inside the intake manifold that the holley hurts with heat. Though the air is traveling at a fairly high rate of speed heat soak does occur. The manifold holding heat also causes the throttlebody to hold heat. A hot intake charge is a terrible thing detonation can do tons of damage. The holley will be useful for cars that need the holley like maybe a 400up ci TT. This is where the holley will make more due to its ability to be ported. It was designed for that use in particular not for a 346 NA car.
Let see if I can explain this......
Thermal dynamics funny stuff.......
you are sitting at the light ready to launch and the car is already warmed up. The holley manifold is hot so now the intake charge due to lack of flow is gettig hotter. You launch now all the cold air rushes into the manifold. since there is a huge temperature difference the hot air is not all used before cooler denser air moves its way in and forces the hot air towards the to of the manifold. Due to the velocity that the cooler air is carrying it will not allow the hot intake charge to go into the combustion chamber, rather it will make a swirl as they battle for the rights of flow passages. Now you have an inefficient flow through your intake. I know it would seem like there really shouldn't be this much activity but there is. Maybe not as much as it sounds like, maybe not enough to make a difference but this is what thermal dynamics says should happen. Once again this is just my .02 cents but get the ls6, i am pretty sure someone can port those thngs anyways.
It is kinda like ripleys, believe it or not.
granted this will go away after the air eventually cools down to constant temp but like i said this is just my opinion from knowlege i have.
