Who does extrude honing ??
 

I have 2 intakes that I would like to get extrude honed to open up airflow a bit. I live near Chicago IL.

Is there anybody in the Midwest that does this or do I need to send them to Cali??

Thanks !!!

You need 500's!!!! :rolleyes:

Figure out a payment plan and you might have a deal !!!

A number of these guys are cutting them out on their own with good results. I was contemplatine sending it to ASM but did not want to wait 6 mos. I never could figure out how it is a 6 mos process. Eddie Young bored out mine.

I cut mine out with a mill the best I could then had it hand ported the rest of the way,I have had several people who would like me to help set them up with top ends who could benefit from professional extrude honing,I would love to hear a source other then azsm,Smitty

extrude hone is an american company, you can send the parts to them.... this link has the us facilities...

I suspect the reason it takes so long is that AZ can't just send one- they have to get a batch together. Maybe "can't" isn't the right word- but you probably wouldn't like the price.

Smokey Yunick was doing the process in his shop back when I was in short pants- attempting to bypass a NASCAR rule on porting. Although the process took days to accomplish. I suspect he was using carbide in a light oil solution and using a diaphragm pump to circulate it.

by the looks of the link Smitty there is a place here in GR. If you need any help i can check it out for ya!

I know a guy that works at extrude hone and he said that there is a link on there web site that will take you there, he thought it was honeit.com, but from what I found it looks like it should be http://www.gethoned.com/ they specialize in the jobshop are doing a lot of NASCAR and drag cars as well. Hope this helps

very very good guess. i have seen the machine he used and it is essentially just that.

OK I called Extrude hone and the place that is set up to do intakes is in Pittsburg. The guy said it takes 2 weeks and it would be 450.00 for each fuel injection lower manifiold :eek::eek: He said they would remove between 30 to 50 thousands of material. Flow would increase and he said avg HP goes up 10 HP.. I will pass at 900.00 for 2 lower manifolds. I can get more than 10 hp for 450.00 each motor. Oh well it was a good idea in theory.

Payment plan seems like the best option...:eek:

I worked in an engine airflow facility for many years. The reason Extrude hone has never caught on is that is DOES NOT WORK. Well, ok, yes it does take out material, but the problem is, it takes out material in precisely the WRONG places.

Cylinder head or intake manifold porting is complicated work. It's not just a matter of hogging out material. The process takes out the most material were the sludge is moving fastest, and very little where it is moving slow. Often this is the opposite of what you want to have happen. (that's a simplified explaination, the more technically correct explaination gets into stuff like Reynolds Number and would require me to break out my college fluids text and would put everyone to sleep)

I recall a coworker tested several heads or manifolds that had the process done to them and they almost always lost flow or the gain was minor in comparison to a properly ported version
