Got my manifolds back from Extrude Hone and Jet Hot. Very nice work by Extrude Hone, but I can't get the pics to upload. Have nice pics of the runners, if someone can tell me how to post them.

 

Sweeeeeeeeet, I would like to see pics

 

you can send pics to hippo206206@yahoo.com and I can post them for you.

 

Extrude honing should be awesome on the manifolds for better air flow. Wish I had did it to mine.

 

send them to ddearborn@stny.rr.com and i will host them for you.

 

Sent 3 pics to T88, have lots more

 

help me out...

what's extrude honing?

Also, any before/after comparision on intake temps??

 

Go to extrudehone.com, or maybe search here. It is a machining process where the abrasive is suspended in a fluid, enabling polishing, deburring, etc. in castings that would be difficult to do by hand. They also gasket match the ports. I have no before/after data, as they aren't installed yet.

 

how much did each process cost? did they do any before and after flow testing?

i think it would be very difficult to get comparison on intake temps as most people here measure intake temps before they hit the intake manifold. iirc....

 

If they did any testing, they didn't tell me. The woman who replied to my inquiry told me to expect 15-20% increase in HP; when I talked to the guy in charge, I told him how impressed I was with that He revised it to 15-20 HP.
Don't know cost exactly; I'll know when I get the credit card bill.
I'll have an idea about intake temps. since I've taken some notes. Problem is, I am also modifying my IC and adding a phenolic spacer at the same time, so I won't know how much to attribute to what.

 

so pretty much if you alredy had your UIM and LIM polished you would have to polish them again after you do this.

Depending on which Jet Hot Coating you choose, it looks polished. It also has much better thermal properties.

 

cmon! make with the pics already!

 

it was around 600 for both UIM and LIM including shipping.

To get the complete effect you should JH all non-radiating metallic portions in the intake path. Although even doing just a couple will probably have a noticable effect on intake charge temps.

I'm looking forward to any charge temp stats you can give us after installation.

 

yeah, I got a quote quite a while back; considered having it done when I put the motor in. Extrude hone is the real deal, it just came down to me not spending the money

 

 

Thanks for posting the pics, Glass Man

 

Looks even nicer than I expected

 

Make sure you port match your gaskets or its all a waist. Actually your could probably just get by with using just some ultra grey sealer

wow looks good!

 

for the price i'm not all that impressed....

but it looks good nonetheless, i'd say you could have a custom LIM/UIM made out of tubular aluminum for that price

 

I'd say you should try No way you could fab both pieces for anywhere near that price.

 

Agreed....unless you do it yourself or are doing it in quantity.

 

Was that for both the extrude honing *and* jethot coating? How much for just the jethot?
