Extrude Hone (facts)
 

Yes, this topic has been covered, but it never seems to cover the facts. I have seen a lot of speculation:

lower torque #'s, higher hp #'s @ higher rpms , slower air speed due to enlarging runners, poor fuel atomization due to loss off surface turbulence, and a few others that I cant think of right now, but no facts...

Does anyone have first hand "facts" on Extrude Hone (other than it being overpriced).

Comparative Time slips, Dyno pulls, any fact based article from a magazine or publication (not a paid article advertisement in disguise, please spot the difference)

I'm curious

I am hoping to get facts not a I know more than you (pure speculative) pissing contest (which often happens here)...

Two facts that I am absolutely certain of:
1: It's shiny.
2: It's expensive.
Aside from those I don't have anything else to go on. ;)

That funny!


But for something that has been so heavily debate on numerous forums (Google it and see) I am surprised there are no real facts. At least that I have found...

All you need to look at is the flow bench and dyno charts of whatever it is you're planning on extrude honing.

Works especially good on oem cast turbo manifolds.
