Thread: Turbo Porting & Polishing

i'm sure there has to be benifit....at least in efficiency

sometimes 7-10hp is the difference between 390hp and 400hp... eh, eh??

this is essentially the poor mans method of the services offered by Extrude Hone

No extreme hone is much more different.
It's a chemical means of removing/polishing material

The Extrude Hone process is a physically abrasive material pushed through the part to smooth the part internally. How is that chemical exactly?

Measured my 18G turbo's wastegate. The flap is 30mm while the hole is 24mm. Could use some boring out, 34mm flap would be sweat, but would be fairly hard to fit.



Well when two physicals objects rub against each other they create heat, a chemical heat!

Sorry must have erased too much what I was saying is
Extrude hone is abrasive and Electrolytic Chemical Machining (ECM) does the same but it's Done chemical

no it is not! Extrude Hone works no different than a piece of sand paper or a grinder wheel. Its abrasiveness is what removes material. The fact that it is not a newtonian fluid/material is what allows it to be pressed through small orifices and cavities and remain abrasive (but not too abrasive) and not change behavior or its properties under various temps & pressures, like a newtonian fluid/material would.....



Youre correct Ben... Saying EH is a chemical process is like saying a piece of sandpaper is chemical process cause there is glue between the aluminum oxide grit and the paper LMFAO...




erase all you want, youre still off. Extrude honing uses a compund, which sure, it has some chemicals in it (what doesnt) but the polishing process happens abrasively not due to chemical reactions! Friction caused by viscous shear flow of a fluid or material is NOT a chemical process!!!

In the end the metal has been mechanically polished, not electrically or chemically.

Can you not read ? I caught it and corrected my error in what I said due to my darn phone and the second post is correct just as I said extrude hone is a abrasive and ECM does it chemically (electrochemically) they are two different processes

I can read just fine... who the hell brought up ECM? lol

your first statement also said Extrude Hone is MUCH MORE DIFFERENT, thats the part thats incorrect.
