I want to make it ***VERY CLEAR*** that any time I say "pound of air" in this video, I'm referring to the mass flow rate of "X" pounds of air per minute. NOT "X" psi of boost.
Also, I messed up a bit on the time stamps, here are accurate links:

The data you provide is underrated man. For the amount of effort you’ve put in it’s sad you don’t have as much recognition as the you tubers with all the flashy cars.

[Huwberts_Emporium]

420hp to the wheels in a Miata must feel like 700hp in a new car.

[Nebbia_affaraccimiei]

and THIS my friends is why I've been subscribed for so long! sweet sweet technical content explained for dummies!

[PistonsAndPetrol]

I listened and bought an NA Miata. Thanks dad.

[themmiatadays]

Did I just watch a tv show long TheCarPassionChannle video... yep and I enjoyed every second 🤙

[FDB]

I have no idea what any of this means but I'm still interested lol.

Greg, this is without doubt THE BEST turbo compressor map video. A perfect real-world explanation (with actual data - no bluffing or fudging figures). It was even better than Brett's video, from GFB, on the MCM channel. Simply brilliant. Thank you.
can anyone give this video a thumbs down? Shame on you!)

[PANTYEATR]

finally, an understandable explanation on how to read a surge map. thanks so much bro.💪

Craig and Craig is the most under-rated auto team on youtubes.

13:49 I smashed the like button so hard I broke my screen. Thanks for the content Greg.

[usafsmoky]

This is an incredible service. Sitting with a turbo’d NA that I built along side your videos, you’ve got the motherload of content that I bet other cars platforms wish they had.

[mikespencer]

Making the complex understandable! Bravo, Greg!

[rokudrifter]

you just answered something that I think about everytime I consider turbo. driving two hours to get it tuned without the turbo plumbed.

[daniel]

I’ve literally sat in engineer lectures and I’ve never had such a quality of knowledge and data provided. Outstanding! 👏👏👏

[edwardbusbin]

Loved the longer technical side of it, keep it up man!

[Hartbreak]

Now I finally understand compressor maps, every time I went into a forum trying to grasp the concept I was welcomed with comments with more mathematical and technical jargon than a Apollo mission to the moon. Now I need to understand the exhaust side of the turbo 😂

[khawajadotd]

I just learned SO MUCH. Would love to keep seeing in depth technical stuff

[alj]

Epic video, love the more detailed format.... You are going to end up getting less power to weight ratio if you keep adding sensors 😂

[madmiata]

Came back to watch again after a few months. Great job simplifying the fancy engineering stuff. My brain has a hard time comprehending engineering technical documents. You made it easy. Thanks man!
