Contour Enthusiasts Group Archives Forums General Group Buy Extrude Hone GB- Directly through EH

For those who've been waiting for an Extrude Hone GB for the UIM's, here you go. I got this email from Rick @ EH in reguards to the rumor about a set price of $285 for CEGers.

"Daymon, Hello the cost of $285.00 is for a group buy of 6 0r more
intakes. I have seen tuck tape on the intakes to protect them.
Thanks,

Rick Miller
Automotive Project Manager
Extrude Hone"

I know I'm not the only one who needs to get this done. Once we have enough, I'll get supply payment info that's directly through EH.

I have a friend who would do this , Is 285.00 the final price with return shipping ...Whats the HP gain if any ?

So this is the uber extrude hone and can be done again to SVT UIMs correct

i think i should let my 3L breathe a little better, count me in!

I have a friend who would do this for sure , but i read in another GB about the same product and they said there was no HP gains at all . . ?

If there was no gain to this, then I wouldn't be spending $285 for it. Gains will depend on your mods. For example, a turbo 3L w/ PnP'd heads will get more gains than a basicly stock SVT from this mod.

Awhile back I got some approx CFU rates from Extrude Hone..
stock = 155 CFU
single= 170 CFU
double= 180 CFU
triple= 188-190 CFU

We also know the SVT heads were flowed at 210-215 CFU (stock is about 195)..and t.body is reportedly over 300 CFU. So the point is that even on a 2.5L the UIM may be flow limiting factor along with LIM butterflies..

For $285 Extrude Hone will port-match your upper intake manifold to your lower intake manifold and hone the manifold another time with a "more agressive" putty. When completed your upper intake manifold will flow approximately 190 CFM. Shipping is not included in the $285 price.

Whats the turn around time?

Will extrude hone effect my manifold if its powdercoated?

don't think that would matter as the SVT UIM's are all powdercoated. If you're really concerned about your finish (as I should have been), you might want to get that clear protective tape to put on the powercoated parts. I was in the last GB and my UIM had wear marks, though not that bad. Most likely was from shipping... from the UIM rubbing on their packing foam.
