How to Improve the Flow of Complicated Parts

[@VertigoGTI]

I haven’t heard “extrude honed” since 2007

[@truthimagination2997]

It used to be expensive back then too

[@FLiPpiNpRidE]

Mike been around haha, prob how he learned it back in the day

[@AndrewKidd14145]

Because it’s not for normies. Only for real builders and engineers. Too expensive and highly specialized equipment.

[@cindysue5474]

@@truthimagination2997 It still is but worth it.

[@karlgross3520]

We had an extrude hone in our plastics extrusion shop. It was a really neat machine. The only thing is, though, is it can make bad turns and slow areas in a head worse. The media is going to go where it wants to, not where you tell it to. You really can't beat porting by hand or cnc. Hand porting, then extrude hone is a whole other level.

[@findtherightbeat]

I remember Lisa Kubo's race car had the text "Extrude Honed" back in the day

[@diegolp5323]

Abel Ibarra too.

Mike always looks like he’s about to bust out laughing when he talks, just a happy ass dude 😂❤

I would be too. look at the collection of vehicles hes standing in front of 😂😂

Glad to hear extrude hone is stil around

[@vashumashu4359]

So cool. Liquid sandpaper.

[@nooneproductions27]

Amazing work old technique but very effective

[@radisnooker5]

I have a civic with the k24z7, so exhaust header is just a big hole in the cylinder head. Any gains to be had from using this process? Or is a head swap still the best way to go

[@motoiq]

4P has made huge gains with this head. This process probably works good too.

[@mikellewis2346]

Head swap would give u v-tec on both intake an exhaust as well as multiple ports for exhaust. But if your using a turbo the single port head can still be used to make great power. It all depends what your doing with the motor an what car its also in.

[@apm3rk]

That’s so smart lol

[@mechticulous8202]

I was hoping to get the recipe for the abrasive paste or something. 😅

[@mikellewis2346]

Would it be worth doing this to a k20z3 rbc intake ??? I see alot of guys cut them open to port them. I dont like the look of that at all.

[@motoiq]

I think it would be ideal

[@cadillac8597]

What cars have heads with the manifolds built in?

[@motoiq]

A lot now days

[@cadillac8597]

@@motoiqyikes - does 1 piece head/manifold improve (stock) performance or a cost saving measure by deleting a couple bolts and the installer?

[@motoiq]

It is for emissions

[@IdEk5627]

Omg i was wondering when someone would use this method. I learned about it in school and always thought it would be great for manifolds and stuff but i wasnt sure how available it was to the US. If someone did it near me i would def get my manifolds and stuff honed

[@realMaverickBuckley]

Its been around for a little over 50 years. Its really for polishing/ smoothing.

[@michaelr5545]

Ive been curious about extrude honing for years but forum misinformation has led me to question its effectiveness. Thankful to hear your opinion, thanks Mike

[@paulmryglod4802]

It was worth tons of flow improvement on old 5.0 intakes where I think it became well known.

[@Fk8td]

Extrude hone is an old method goes well back over 20 years.

[@richard-mai]

Concept is so simple I can’t believe I couldn’t think of it!

[@metrichotrods1763]

I knew this before he said it because i read about it when he wrote about it 20 years ago

[@Unknownexplorer666]

That p10 primera though...

[@Phat_rabbitt]

Extrude honed😂

[@DeathIncarnate306]

Vehicles should have these types of processes done at the factory!

[@papopleto]

Mike Kojima is the goat!!!!

[@renemunguia4655]

Nice p10 in the background. Turbo sr20 or na

Would be nice to see it in action the porting process please?????

Thank you so much you guys are so great!!!!!!!!

[@muasboy]

I remember reading your book, that u wrote years ago. And you mentioned extrude honing. I was amazed

[@scoobee9]

That's awesome, once you started to describing the process i knew exactly what it was. I hadn't heard about it in a very long time. Thanks.

It is way more power than that.

[@MFRtherapy]

How to improve flow, dont install skunk2, aka junk2

[@motoiq]

This is actually probably the best stock configuration manifold on the market.

[@MFRtherapy]

Nope, stock configuration equals leave it alone or go to a different honda intake mani. I have pictures of the trash they sell. I also know people who have worked for this company. No true honda modder is proud to have junk2 under the hood.

[@miquelanesto1762]

Something recommended by this channel that is relatively inexpensive.

[@rudimerm7686]

Yes, that is exactly what I was going to say.

[@dinosshed]

Pump wet concrete through it. Add a stack of dishwashing liquid to prevent it from setting.

[@RandomlnternetGuy]

Didn't even know that was a thing. Thank you

[@droboyjr]

I mean that’s super cool and all…but where tf am I gonna find a shop to “Extrude Hone” my intake manifold? And on top of that I’d be curious to see how “relatively inexpensive” this process is for a regular joe.

[@motoiq]

Sent intake to Extrude Hone
