Inside the MS362

[blsnelling]

As promised, the video is done. As promised, it's late, lol.

I couldn't be more pleased! The 362 really responded to the porting. Based on this round of testing, it was 26% faster than stock in about 12" wood, and 18% faster than stock with the 20" bar buried.

In the smaller wood, it was neck and neck with the ported 361. In the bigger wood, the 361 takes over and was 9% faster than the ported 362. It just has more torque, plain and simple.

So really nothing too surprising here. The 362 responded very well to mods, but still not like a non-strato saw.

But don't look at just the numbers. This ported 362 is a pleasure to run. It's very strong and is very smooth. It'll get better fuel economy as well. Only for the racer is the strato design that big of a deal.

Looks really good.

Well said and :agree2:

BTW Both 362's are really new and they will only get stronger.

Thanks for hosting us tonight, Andy. It's always a pleasure.

 

[Andyshine77]

No problem, it's always fun to hang out with you guys.

good work brad, she really holds the rpm in the cut, I am supprised at the low RPM with the port timming like it is. You can tell it really dosnt like to be loaded hard. BTW blood sold me that saw so you can just go ahead and ship it to me.....

Thanks for the thread and all your hard work Brad!

One thing to consider on this mod. . . It's the first one. The "super-secret recipe" for porting these strato saws probably isn't found yet. There are probably more gains to be had, it's just a matter of time.

Thanks again for posting all this.

Nice work Brad, and Thanks!

I ain't got a dog in the fight, but the matter of fingering out what makes the new strato horrors tick, is deeply interesting.

Maybe with some fussing on port timing that difference between the 361 and 362 in larger logs can be ironed out.

Stay safe!

Great work Brad- being on the leading edge of knowing the strato-charged engines is a huge asset... though I really like how the Solo 681 came in and took charge.

 

[woodgrenade]

Great vid, and job well done. The saw made some great gains and that is all you could ask for. I hope the vid I posted before served as inspiration! lol.

 

[BloodOnTheIce]

Looks good, I can't wait to run it. And no I didn't sell it and it's not for sale.
And this saw only has a few tanks of gas through it and should pick up a little more when it's got a few hours on it. I didn't have this saw ported to to beat a 361, I wanted to see what could be done w/ this new technology. Thanks again Brad.

Brad: when you do a port job, how do you know how much material you want to remove, and how do you measure how much has been removed?

On this job, how much did you widen the ports or change the transfers?

What was the final compression?

How wide did you go with the muffler mod?

Did you advance the timing?

Will you post pics?

and Brad, dont forget your mothers maiden name....

 

[Fastcast]

Interesting stuff!....Great work gentlemen!

 

[stinkbait]

Nice work Brad!

Dang that 681 is fast for stock!

 

[constantine]

Thanks for all the hard work and the excellent video. I won't run out to trade my 361 for a 362, but I'm getting a 681 for sure! It will take time and experimentation to figure out the best way to achieve maximum performance from the strato engine. I'm sure that even at peak performance, there will be tradeoffs between strato and conventional designs. The fuel economy is undeniable, even at this early stage, however. Keep up the great work and thanks for sharing it with all of us.

You can tell it really dosnt like to be loaded hard.

It does prefer a "medium" touch. The 361 can be loaded quite a bit more.

20%-25% are respectable gains for a woods port on any saw. I really think we're seeing the limitations of the strato design here. I'm sure you could go farther, but it would beyond the realms of a wood port. A popup would likely help a little.

Maybe with some fussing on port timing that difference between the 361 and 362 in larger logs can be ironed out.

See above.

... though I really like how the Solo 681 came in and took charge.

Kind of puts things into perspective doesn't it?

The saw made some great gains and that is all you could ask for.

I'm very pleased with the results. I was high 5ing Nik as soon as we timed the first cut. I knew we had success.

Looks good, I can't wait to run it. And no I didn't sell it and it's not for sale.

You're quite welcome. Thanks for the opportunity to be the first to go inside a 362. That was really cool. I know beating the 361 wasn't the ultimate goal, but I also know that's a huge question on everyone's mind. So I had two questions going into this. How does it compare to stock? And, how does it mod compares to the 361? Don't let the fact that the 361 was faster confuse you. The gains to this 362 were everything, and more, than I hoped for. It's just a different saw.

 

[bitzer]

Will you give us the pics man? The video is only the teaser! Im curious as hell to see what you did! Very cool Brad! Thanks for keeping it out there!

 

[blsnelling]

Dang that 681 is fast for stock!

And it's still wearing a little 7-pin rim. I'm out of 8-pins or it would be measurably faster yet
