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

[KG441c]

I love my Monkied 362c. Im doin all I can to resist selling my completely redone and ported 026 to get a 261 to get a masterminded sticker! Randy I sure like that new Monkey with the gun avatar that was posted the other day?

 

[Mastermind]

Did you feel like Dex???? Was there a big gain over stock to you?

 

[Mastermind]

I've not been able to spend a lot of time on the trigger of one like I'd like to.

 

[MustangMike]

You need to put time for that on your new schedule!!!

 

[Mastermind]

Maybe in December....

Totally woke it up. A ton more torque and you can lean on the saw without it tapping out in the cut

Got the cow caught and got a couple of heifer calves in the field now.........thank goodness.
Did I mention that I really like this graph??????

Best advertising I've seen from a ported saw! Proof is in the pudding.

 

[MustangMike]

We need to get one of these new MS362Cs on that dyno. If what Dex says means anything.....his 362 was a more impressive gain over stock than any saw I've done for him yet..........if what he says can be believed.

You have a volunteer!

Are the numbers you use for the 362 similar (or the same) as what you use for the 261 & 441, or does each one like something different?

True story..

My 460 was pretty mean stock and is a Machine now , but this 362 seems to be pretty bad azz unit!!

 

[Mastermind]

Good question Mike......

The exhaust height will always be different on 50, 60, and 70cc saws that I do.

Transfer height will be in some cases too. That is the number I work the hardest to dial in just so.

I'd rather not post the numbers I use on these M-Tronic saws though.......

 

[KG441c]

Randy do u see the mtronics saws having an advantage or disadvantage as far as being durable compared to a properly maintained and tuned non mtronics saw?

 

[MustangMike]

Randy, I don't blame you at all, but it sounds like you have got them really dialed in!

Dex is making me drool to get it back!

 

[Mastermind]

Randy do u see the mtronics saws having an advantage or disadvantage as far as being durable compared to a properly maintained and tuned non mtronics saw?

So far..........I think the M-Tronic system is very nearly bulletproof.

And......they tune for max RPM in the cut. Win Win!!!!!

mtronics compared in durability and peformance compared to the older 026,036,044,etc?

 

[Mastermind]

It's just a carb.....no different really.

 

[Dieselshawn]

Ohh yea!
Hey, question about the Dyno: how do you get rid of the heat?

I use a much larger size oil tank to keep the oil temps down than chad has.

It was by accident actually as the 5 gallon tank was on sale for only $50 cdn with the oil ports and vent cap. Couldn't pass up on the price so my table was designed to hold the larger tank.

I've had 5 large saws, 2 of them masterminded 660's, 1 modded husky 390 and 2 stock 660's do several hard pulling runs each and the oil only got warm to the touch.

This is over an hour of dyno pulls, swapping saws, tuning.

The pump has only reached half capacity so far..... Now I need a modded 3120 husky to try.

 

[redfin]

What were the numbers on the 660s?

 

[Mastermind]

Good idea on adding oil capacity. I'd probably build a stand for the dyno......and incorporate a large tank in the stand.
