I'm playing with some M8 take-offs while I'm here at Reher Morrison's shop.
I gotta say. I'm very impressed with what these are capable of. They have ALLOT of potential, ALLOT!!!
In stock form, they flow more than enough for the relatively small displacement motors they come on.
But for larger motors, these things have some enormous potential. I got the Intake port well into the 350s
without touching the valves or seats, (that's tomorrow's lesson).
I put a chart on my FaceBook page, (MCE Performance) of the initial go at the intake port. No seat work was
done up to this point. I expect some even better results after I fix Harley's chitty valve job. LOL
Keep your dick in a vice!

Here's a link to the preliminary flow results (in case you don't have FB)
