I mentioned awhile back ago a Nitro Fuel saw and E85 fuels. It's the only thing that makes sense, nitrous not practical turbo many have tried and failed still not practical. E85 in a car takes double the injector size and tune. E85 is huge performance in cars. I don't know much about chainsaw building just throwing ideas out there. I really enjoy channel. Really like to see a ported 462 vs 572 xp ported, piped on nitro dyno shootout It should get the algorithms going crazy at least in chainsaw world.
Dam Joe you do a great job pouring that fuel from the bottle to the saw without spilling a drop - I'd have that all over the bench even using a funnel... 😉😉
Very interesting little look into that exotic fuel world…. Why the JB Weld outside the upper transfer port? What is that JB sealing it back up from? It appears that the muffler is just open with that big hole? How is that open exhaust not just smoking that piston? Thought you needed some muffler to not smoke the piston??? That’s a significant power jump from the fuel switch only??? Under 8 to over 10 is a hell of a jump up! 10hp out of that little engine is pretty wild stuff! The way it’s reving up to the stratosphere definitely had me thinking can it hold together at 15,000??? Holy smokes man I bet that son of a gun blast through that 8x8 or whatever you guys are using in a hurry! That would just be a heck of a lot of fun to get to run a couple of times! Very very cool stuff!
The jb weld it from grinding through the transfers or adding boost ports. I didn't pop the cylinder off. As long as the tune is ok, and oil in the mix the muffler outlet wont smoke the piston. Short bursts of 15k+ seem to hold up well. As the rpm in the wood is a bit less and races are less than 6 seconds most the time
Used to run alcohol/nitro in RC monster trucks T-Maxx etc.. that was 20yrs ago.. I know at the hobby shops you can buy 10-20-30-40% Nitro fuels and it almost looks like thats whats being run in this saw. Try some 30% nitro mix once it should gain even more power. This is very cool but not much good for cutting firewood or falling timber. Still very cool! Can't wait for the next video 👍
Interesting to see your pretty close on the torque with a normal build, race saw just tuned for much more RPM. I have no real interest in race saws as I actually use the things for work, you also wouldn't get me running nitro methanol indoors. Any of you guys run saws on E85 or pure ethanol?
Takes higher compression to gain power from racing gas like 110. A stock saw would probably lose power from higher octane as without boosting the compression higher octane fuel burns slower. Now a ported saw with decked cylinder may see some gains from premium pump gas I bet.
Nitromethane is so volatile it creates more heat and pressure then even high octane fuel it is similar to the explosive component in TNT with nitro producing more explosive energy by weight and the nitro doesn't require any oxygen charge or boost to compression to be effective it will make power just from ignition even in a vacuum which is why nitromethane was once used to fuel rockets in the form of tetranitromethane which is an even more explosive version of nitro lol. What's crazy is you can literally make rocket fuel by combing isopropyl alcohol and nitric acid over an extended period of time although it would take a lot to yield very little and it world take further processing to extract the pure tetranitromethane it is one of the most simple high power fuels you can get.
Awesome to see how exotic fuels effect the power output on these small enhines!
You'd never know by the way it idled it was on funny fuel. Nice build to whoever it belongs to. Thanks for the video Joe!
I was very impressed with the manners this saw had. Better than some stockers lol
@@dynojoemods2764 better than many xtorq's lol, but they are still great runners with a nice sweet spot.
@@dynojoemods2764 So true.
@@dynojoemods2764ha it is a well mannered saw, if never used that lingo to describe a saw but right on lol
@@dynojoemods2764oil mix 33:1 ?
Nitro the ultimate power adder. A bit more work but well worth it in a race saw. 😎👍
That was fascinating. Thank you
Love the new backdrop and content! I'm on the lookout for more signs and flags.
Absolutely amazing! Thanks!
I've been waiting to see a nitro sae in your channel! Awesome!
Great video mate 😊

Nice job Joe.
Have a great week.
Thanks, you too!
I would love to see a work build with nothing but a carb and fuel swap. That would give you a good bench mark for fuel change only
I enjoy your videos.

Can't waste the go go juice....
Wooo woooo nelly! Shes come to life, haha scared me a little
Very nice video Joe!🤩🤩
Gonna be a monster!!!!!
RIpper for sure!

Thanks for showing this i have always wanted to try this !!!
Nice 😮
💪🏽💪🏽💪🏽👏🏽👏🏽👏🏽
Low tops hard to come by in USA? You do great work joe!
Cool 😍🤝👍
i bet it smells so good
Good video
You should get the fuel flow and ignition timing up to where nitro wants to be. It will RIP!.
Awesome video Joe where do you get the nitro methane fuel? Is it RC car fuel?
Make a video on how to convert the carb
When and where is saw fest at?
I wonder if AT or MTronic could compensate for nitro?
I have a question. Would it be worth the trouble to run E85 in a saw?
Wow that was awesome. 😂
👍🏻👏
Do you do port jobs for people? And if so how much do you charge?
Keren bos 👍

Though making a shit-ton more power that fuel is very toxic to life and corrosive to saw internals . Unless trying to get a world record …….
Yes I run a 660 on E85
I always wondered how that nitro methane would react if you mix in with gas 20%. It would be nice to get a little extra power out of daily usage.
The 2 fuels will not mix together. Nitro propane yes
@@fabzacres-blackcat ah ok thanks
I'm curious what av gas or 110 vp fuel does on the dyno. I've ran both in my 046 but don't have a dyno lol

Whats the purpose of the epoxy on the ports?
Add more volume/extra ports
Nitros mental huh.
