I thought you presented VE very well John and yes my head exploded just like the emoji’s lol ! I’ve done a lot of VE testing and used it primarily to test MAF sensors, although it’s great for testing air efficiency as well. Something to note, you can qualify a MAF at idle using the 1 gram/sec. per liter and have it be skewed at any rpm off idle. Using a piece of graph paper and drawing a line at varying rpm is a good way to test if a graphing scan tool or scope is not available as long as you can record the data.

That’s great and all, but you want to get your MAF value at peak torque rpm not peak rpm. VE is greatest at peak torque rpm, and I’m not aware of any engine that has its peak torque at redline.

Thank you so much, this is exactly what I was looking for.

I believe there are some NA SBC racing engines with 23 degree heads that have achieved over 100% VE. Am I right?

94% is nuts for a dead stock "grocery getter" engine! I remember back in the early 80's it was assumed that if you had ~85% on a non boosted engine you were rockin'. Of course, we had no practical method of testing that back then (here, let me pull my heads so you can slap them on a flow bench... cough...). Not to mention that was just a portion of the equation. Man... times they have-a-changed! And for the better here.

Great job! I should have stayed in school. Where’s my calculator at😂😂

Is there a VE calculator that can be used with MAP only engines?

why can't i find knowlegable mechanic like this in houston now that scotty is gone.
