Dyno tested....Mastermind's ported 261cm vs Stock 261cm Gotta see this one.

[DexterDay]

Where do u get ur boxes?

Either the P.O. or WalMart.

Walmart has cheap "Heavy Duty/Duck" brand boxes. They are double corrugated. They look thinner than a standard box, but are twice as stiff.

The P.O. has thinner boxes, but they work. Or you can go to your local drug store or Dollar store and they will give you almost any box you ask for.

You can see the 2 layers in this pic. Most times I just use what I have (whatever saws come in), but if I am out. These 2 options are where I go.

You know the 461 ain't a Strato saw no? At least not like the 261/362/441.

I want to see a 460DP vs a stock 461. My hands/ears told me they are close....

It's not an Mtronic, but it's still Strato..

I want to see a ported 460 against a ported 461 My 460 is mean

 

[MasterMech]

It's not an Mtronic, but it's still Strato? No?

Nope. Check the piston design and the intake ports. Where are those fresh air ports anyways?

Yes it is!

Then someone needs to please tell me what the difference is in the 460 and 461?

I thought it was Strato?? What's the difference in the two?

 

[bryanr2]

dont know about the 460 but the 461 is quad port

 

[Mastermind]

The 461 recycles some of the exhaust down the transfers.........

But it's not what I would call stratified.

A quad ported 460 is what I see.

Top end is totally different design. Quad transfers and long entrances that start near the front of the jug outside of the actual cylinder instead of the two shorties on either side like a 460 has. And a weird little aluminum hard-on in the crankcase that should kick extra lube to the wrist pin. Some minor differences in the carb jetting too but if you were locked in a room feeling around in the dark you would call it a 460.

Then I have to see a comparison. .

Chad.. PM your addy and tell me when and where. I wanna see the difference in gains.

It's probably world's apart, but.....
I love the 036 (dual port) and I hated the 361 (quad port). Hated it.. Had 2 and disliked them both. Both very Minty..

I plan to have both a dual port 044 and dual port 046 at GTG, both with HD-2 filters, and I have advanced the timing on the 046. (the carb rebuild kit for the 046 should arrive tomorrow).

 

[MustangMike]

I'm reading too fast, you guys are talking the transfers and I'm talking the muffler. But I guess for both those saws, both apply!

if i was 10000 miles closer i would gladly offer for the dyno the 461.

That's exactly what I was thinking when I watched your build thread. I was very impressed that Stihl went that way with it. I almost got one of them when I saw the better AV. Then I saw the price... ;(

How did they improve AV? I thought the 461 still had the old system?

I can test. I'd like to have all saws at the same time after that 461 gets ported.

I truly do hate to ask for help but I dumped over $1000 in my dyno and spent a lot of hours building it. Would you guys be willing to pay for a dyno test? What's fair?

 

[dl5205]

Wasn't there quite a discussion recently on the claimed "delayed Stratification" (or somesuch) of the 461 or similar? Where WAS that argument?

I'm thinking if I were to offer dyno pulls to the public it would be At Least in the $75 - $150 range. But hey, I'm a Capitalist.

fully instumated snow and bike dynos get 150.00 a hr.. But they also cost thousands of dollars...depends on how much of your time is in it to test a saw....from hookup until you take it off how long does it take? And what do you think your time is worth?

To high for me maybe $25-$50 and I'm not expecting anything from the saws that are being sent to me that was just discussed.
