I kinda hesitate to get involved in this conversation for some reason. I will say I have used a riffraff 4x4 billet wheel in both mine and my dads trucks and were very happy with their performance.

This was a huge part of the reasoning behind why I started working on the turbo matrix. Hopefully by looking at a chart with lots of the variables broken down in an easy to compare fashion we can start to see some trends in what makes things work well in different situations.

I have one of these “different trucks” that didn’t suit well to a combo that works very well for most people.

Agreed.

Agree again

Yep, agreed and a good chart to help visualize it. It’s all about those beautiful little oxygen molecules and how many of them we can get into a combustion cycle.

Good point, I need to add my elevation to the information on the chart. I’m at around 680’ right now according to my phone.
You are correct, I do not know how the elevation effects the AIS.
If the info from your linked page holds true it would mean you have to move A LOT more air to make your truck work at elevation.
But... the air is also thinner, so does that mean it will actually flow through the filter easier? Oh the questions keep building. Science is hard.

This is easily seen at the drag strip. You will pick up considerable ET once the hot summer day turns into cool night.

Informative read. Shows the extra boost required to make up for the lack of oxygen in the less dense air pretty well.

This is a very valid point.
