Husky 359EHP

rahtreelimbs · January 20, 2005, 08:50:14 PM

I got my Husky 359 built by EHP today. I was told that Ed builds his saws with torque in mind. This is very true. This 359 IMO will run or slightly exceed a stock 372.

Good Job Ed!!! 8) 8) 8)

thats what ive heard..enjoy the heck outa u saw.

Rich it would be better to say they have horsepower cause yes they have alot of torque but it is at 13,000 rpm's in the wood under load, I think you are going to have to either gear that saw up to a 8 pin gear or cut your rackers more, .025 is not enough for a 7 pin , it has the power so might as well us it, have fun

That brings up a good question. How do you go about puting an 8 tooth sprocket on the 359? I believe that this is the small spline.

ehp · January 21, 2005, 04:58:07 PM

Rich I never took your clutch off to see if it is a small or big spline,your 357 should be a big spline so you could just switch the complete clutch with your 359 clutch, if not I do have 2 set ups here because the 346's once set up for racing use the big spline, and what I have done on the 260's is machine the small spline done and get the big spline part and press it over the small spline and tig weld it together , works great but just switch the clutchs and make sure you change the oil pump gear with it because it will not work with the different splines

woodsjunkie · January 22, 2005, 01:22:50 PM

Ed,
Question dose the 359 come out ahead of the 357 after all your work is done?

ehp · January 22, 2005, 06:00:50 PM

Yes it is faster for sure, but you have to use the power , it has more torque at a higher rpm, than the 357 because it doesnot have the full circle crank in it , the 359 has the same design as the other saw like a 372 in the way the crank is design so you can get more air into the crankcase, more air more power but you need to do alot of carb work because it needs more fuel but mostly on the idle side circuit .
Rich's saw I know has alot of power and if you set it up so you donot have to push hard on it , it will surprise anybody,
I know here when I tested it I used a square ground work chain and the rackers were at .035, cutting hard maple it was still pulling over 13000 rpm's in the wood and that is what it drew down to and it was only turning 14200 out of the wood so not much drop in rpm's .
Lok at the last get together , Hunter's 359 which was brandnew and only had about 1 tank of fuel threw it was beating alot of the ported 372's and other saw at that show and saws like Crofter's was only .3 ahead so yes the ported 359 is a real animal

devo · January 22, 2005, 06:54:04 PM

Ed,

Can you run that past me again. Are you saying the crank on a 357 physically takes up more space, therefore less space is available for the air. Also what sort of work do you do to the carb.

Not looking fo trade secrets here, just trying to understand it all. ???

ehp · January 22, 2005, 08:32:22 PM

Yes the 357 has bells on its crank so they call it a full circle crank , the 359 has a pork chop crank like most saws. On a snowmoblie motor or bike motor they always try to stuff the crankcase so it is tighter but a chainsaw has a crankcase that is to tight to begin with in most cases , When building saws you fill the complete case and jug full of oil to see how many cc of volume you have, yes you block the intake and ext ports and fill up to 5 threads showing in the spark plug hole, now you already know how many cc of volume your motor is so now you take your jug cc and munis it from your total cc of the complete saw. so now you would know how many cc'c your crankcase really has from the inside of your piston plus the case .
Take that number and divide it by the cc's of the saw like a 3120 so 118 cc. This will give you the crankcase ratio. A 3120 normal stroke is 1.47 to 1
the 1.47 would be the motor cc ratio so if the crankcase is bigger then the ratio number would go down , now the best you can get is 1.20 to 1. this ratio will give you the best horsepower ratio you can get but the bigger the case the more fuel it is going to need to run because of more air being allowed into the case.
Everything like pipes and ports I do is done on a computer and it has a dyno built in to the program which works , You would be amazed at how much more horsepower a 3120 would make if it had a 1.20 ratio, your horsepower almost doubles just doing that alone, but then you will need double the fuel and most carbs are not up to that task , then you also have to worry about stuff like the crank breaking , to much heat because the motor was not designed to cool that much power, there is alot of little things you need to look at before just thinking well this is what I am going to do, it is hard to put back metal you already machined out.

devo · January 22, 2005, 08:48:32 PM

Thanks Ed. I always thought of the work you guys do to mod saws as kind of an art form, I had no idea you used so much science in it. My hat's off to you for being smart enough to figure that stuff out. Got me wondering what you could do with my spare 036 thats gathering dust in the shed. ;D

ehp · January 22, 2005, 09:08:21 PM

Make it go faster pretty much. I know I am happy with the 361 that belongs to Jokers , that saw turned out real nice , yes the 036 is different but it will work just as well once done

ehp · January 22, 2005, 09:14:33 PM

If you build the same saws all the time then not much R&D work is needed once you figure them out but with the saws changing every day now cause of the emmisions standards the gov. has set ,it is nice to be able to put your port numbers in to a computer before you start porting and see if they will work , and now with all these different saw I could be working on a MS200T in the morning and a 3120 stroker alcohol saw in the afternoon so it saves me alot of time and money

woodsjunkie · January 23, 2005, 05:19:15 AM

Ok Ed I will have to take your word for it for now. I did own a 2159 ported by Ken Dunn nice saw runs real well but not even on the same page as my Neigerized 357 XPG.
Perhaps we can all get together and have some fun in the near future. I am thinking about having something hear at my place. I am kind of centrally located for a lot of the guys and perhaps would give more a chance to come. Would you be willing to make the trip? ???

ehp · January 23, 2005, 07:37:20 AM

I am not going anywhere until May that is along ways away, Hunter and Crash Banger are also going to have a get together as well so there will be lots of these, But if you want to see a 359 just go over to Hunter's and run against his

jokers · January 23, 2005, 09:31:37 AM

Maybe I could make it over to your place Eric, I have a Jonsered 2159WH that Ed built that runs pretty smartly and those heated handles sure are nice when it`s cold like it has been lately. Anyway, since Dan Henry says I don`t know how to run a saw, I wouldn`t be any threat to anyone`s ego, but you could get a feel for an EHP 359/2159.

I also have the MS361 that Ed built, but they don`t take mods as well as a 357,

!, so it might not be much of a contest, but atleast it would be fun.

When is the get together?

jokers · January 23, 2005, 10:11:26 AM

Hi John,

I could help you get your hands on a 2159 with heated handles but what about shipping and duty to Africa? ;D Could you meet us in O Hi so that I could just give it to you?

Russ

Gypo Logger · January 23, 2005, 10:49:23 AM

8) Russ, I've been cutting wood here on the border of Congo and Gabon. Mostly Zebrawood and Burmese Teak. At 2500 metres in elevation it does get rather cold, so I will take you up on the offer of the 2159 Sno Pro. I'll meet you at the get together at Woodsjunkies.
Ed, how will the 2159 perform at such a high elevation?

Hunter · January 23, 2005, 11:15:29 AM

I have both the EHP357xp and the EHP 359.
They are great saws. I grab them over quite a few others.

Woodsjunkie,
I can always bring my 359 up when I come to pick up the grinder you said you were going to sell me. As a matter of fact, I can be up to your place in about an hour or so. I just have to make sure I stay in cell range, with the wife about to give birth to the real HUNTER.
I figure I could make a few cuts and head to the hospital to see him being born.
Id like to see some pics of that Neigerized 357.

Give me an idea and I will find out what it is, and send it to you, or if you want to keep this one I can delete the other one and fix or remove your location information on this login. One login is all one needs.

Gypo Logger · January 23, 2005, 09:13:05 PM

Hi Jeff, I think it was Crazy Canadian or something like that, but Lottarocka is ok.
I'm not really from Africa, but it sounded good at the time.

Hopefully I will be able to put something together hear when the weather breaks some.
If I can muster a get together I hope a lot of the guys will make the trip especially guys like Russ and Hunter. I know I have a lot to learn with my sawyer skills and it would be great to take some pointer from such experienced sawyers.
John you know there doesn't have to be a get together for you to stop by you are always welcome. One thing I want to make clear if I do have something hear Cliff and his boys will be invited.
Will have to wait and see what the weather dose as well as my recovery.
