After Speaking with reps from EXTRUDEHONE @ the SEMA show and expressing what we would like to have done, we (Tom Payn/Payn tech, myself) sent a ITR Intake manifold to them. I will be picking up my ITR intake manifold from EXTRUDEHONE @ the PRI show this weekend and we will be testing the manifold back to back against a stock manifold on a MD chassis dyno. I will post results as soon as we have them.

Has anyone here had their ITR intake manifold EXTRUDEHONED and then dyno it? What kind of results did you see?

Thanks Mattj

No, don't have my IM Extrude honed, but glad someone is testing one

 

I've heard it won't make much of a difference - but what do I know?

Props to you and your test.

 

I am curious to see what kind of gains this will produce. I was thinking of doing the same at one point.

 

Can't wait to see the results! I did mine during a build up so I don't have before and after!
Hope I did not wast my Money

What kind of motor? Mods? turbo or N/A?

 

Way to be a pioneer, we dont get that much.

I dont know about honda's of course, but my BMW motor builder friend swears by ExtrudeHoned IMs for his motors.

I know if I had the extra funds and an ITR motor I'd get most of my stuff Extrudehoned just for better & smoother flow.

But I don't... so I can't... Yet!

 

Matt is this the same IM that was milled?

 

how much more does the honing cost to get it done this way?

 

i too have heard that extrudehone'd manifolds really doesnt do that much but i would love to be proved wrong

Steel Reserve OWNS

 

 

hmmm.....
I would like to know more on this.

 

We had one done before on my friend's itr and dynoed, didn't seem to make a difference. I think like 1-2hp more. I my opinion it's not worth it for the price. It just flows better that's all. BTW it's for sale if anyone is interested.........

I'd say it would make a couple hp's but not a big difference like it says above, however, it might make a bigger difference based on set-ups (ie. turbo). I believe this was a post a while back (year/or so ago). might want to try a search.

 

I think there wouldnt be good fuel atomization with the runner so smooth.

 

Can some one please aducate me on this topic & xplain to me what xactly does xtrudehoning consist of?

 

i beleive its some type of fluid that instead of usuing hand type tools (not normal gargage hand tools) the fluid is pushed through the intake manifold to smooth and open up the chambers in a peice of metal..

on a side note, first time i had steel reserve was at big sky, and i got a bit toasted and then proceeded to brake my glasses in some deep powder

 

I don't have any answers yet as to the cost or what kind of power it will or will not make. I'll post the results and dyno charts as soon as we have them.

Mattj

 

I don't understand how it could mess up the fuel atomization because the fuel doesn't even really touch the intake manifold. It just pretty much goes straight into the head. (i could be wrong though) I have an extrude honed intake manifold sitting in my garage. They are incredibly smooth. It is also HPC coated for heat, so if it doesn't yield any power than at least it will help with heat. But I do remember..... I want to say topspeed (some head porter in florida) Dyno tested one on an itr and he actually posted the chart on here a while back and it should gains of 4 hp mostly across the whole board, but it will be interesting to see what these results come out to.

Thanks for the link. Now, lets say we send a head to Portflow for a small port & polish job. How does that compare to getting it done through the extrudehone process? From what I was able to read in the link, the extrudehone process is ideal for smoothing out the hard to reach places where the polishing tools can't make it. But aside from that detail, is the extrudehone process better than getting it polished the way portflow does it? I'm trying to understand the subject better that's all, thanks.

 

So, if the air is going through too straight, there isnt a little turbulance, the the air will be too tightly packed, and the fuel won't blend well with it.

 

ITS NOT A FLUID, ITS MORE OF A PLASTIC ABRASIVE THAT GETS PUSHED THROUGH WHATEVER AND IS GOOD FOR SMOOTHING OUT TIGHT PLACES THAT A PORT AND POLISH (GRINDER) CAN'T REACH

 

YEAH KINDA........ I THINK IT HAS TIME TO MIX AS ITS GOING THROUGH THE HEAD THOUGH.
EXTRUDEHONING IS MAINLY USED TO GET TO AREAS A GRINDER CAN'T. IT MAKES AREAS A LITTLE BIGGER BY REMOVING A LITTLE MATERIAL AND IF YOU USE IT ON THE MANIFOLD IT SHOULD PROVIDE MORE AIR, WHICH ISN'T A BAD THING. DUNNO IT'S DEBATABLE THOUGH.......
