lol, damn you Ultra I was thinking you was a saw builder, you pulling my leg here. What would you use the smoke wrench for anyway,lololol

Ultra likes the small smell of burning magnesium, in the morning... Hey Ultra, aren't you supposed to be till'in the land?

It would be easier to do it yourself if you have measuring instruments and a die-grinder. I can give you my specs for the 046/MS460. I don't modify saws unless they are new as it takes so long to clean everything. If you pm me with your email address I will send the information you need as well as part numbers for some components. The 046 takes very well to modifications. Although it is a 77cc machine, when done properly it will easily cut with a stock 066/MS660. They are also a very tough saw regarding rod, crank and wrist-pin.

Sounds like a plan. You say it will cut along side a 066, now thats a hefty increase in power, must say. I must say in advance I've own a new 066 a few years back and this 046 was fairly new as well. Both were bought in
1998. The 046 surprizing ran in 20inch wood as fast, if not faster than the 066. In big wood with bars buried the 066 would pass it but I gotta tell ya this is one unusual 046. It honks. Even my ole Stihl rep told me once its the fastest cutting stock 046 he's ever seen. It runs so strong I sold the 066 a year or so later. I'm gonna pm you my e-mail now buddy. We're gonna build us a hot rod thats already hot, can't wait to see what this thing does with your suggestions...........................

THALL you need to start the 066 up first before it cuts..

that would be "stihl TOO wet..."

Too Wet? when does winter end out there? I've been till'in for weeks now..


In about 1 week I will send my wife out with her 4x4 oxen to start working land .. She is learning to build saws rite now and learning to weld..

So that leaves you on AS sippin' whiskey? Nice, I want your job!

Now Ultra you know damn well a man can't run two saws at once. I had the 066 running although it was sitting on the ground while I was sawing with the 046. Wait a minute, that explains it,lololol

I figured you already tried to modified it, and now it runs in reverse! Try reversing the chain:D or sharpening the back of the cutter. Maybe Simon can help?

Yes, he was right ha ha, but they have a short and terrible life. The brake mean effective pressure on a nitro-methane, blown engine is incredible. That piston alone uses 4 liters of fuel in 4.2 seconds. They are kinda thirsty engines.

That is less than 9 US gallons. You must be talking about at .25 throttle. LOL

I am familiar with the formula you posted, but as it pertains to the internal combustion engine there seems to be a flaw or exception not taken into account.

Case in point two small block engines both making 300hp at 3200rpm can have very different torque outputs. I've seen it on a dyno. Simon you are correct as hp is a function of torque and rpm, but something is missing here.

Then there is something wrong with the dyno. I don't care if it's an electric motor, diesel or otherwise. If a rotating machine is developing 300 HP @ 3200 rpm, it is producing 492.39 lbs.ft of torque. Period. You are getting confused with torque curves, the graph plotting torque vs. rpm. These graphs are different for different engines but at a given intersection like you described, the numbers are identical unless you can somehow blow Newton out of the water by violating the law of conservation of energy.

Ok Simon how about 95 hp at 6000rpm ??

We have a harley that is 95 hp 101 tq @6000 on 2 different dynos how can this be..
Dynos measure torque, they use this information at a given rpm to calculate HP. If you are developing 101 lbs.ft of torque @ 6000 rpm you are producing 115.38 HP. Sometimes there is a bit of confusion between rear-wheel HP and crankshaft HP. This muddies the waters a bit. You always lose HP through a transmission due to heat and friction.
 
Ultra, There are many variables with chassis Dyno's. Is it a mustang dyno or Dynojet? The mustang Dyno's read lower, because they put a realistic load on the drivertrain, whereas the Dynojet is a basically a set of resistive rollers. Dynojets always read higher.

Is that STD or SAE corrected? That makes changes and differences too.
