[@RedfishCarolina]

If I understand nitro, it's self oxidizing, so adding as much as possible without hydrolocking the pistons allows you to reach ABSURD compression. I'd love to see what the spark plugs look like after this lol.

[@SpencerHHO]

Nitromethane is CH3NO2 so yeah it carries a lot of its own oxygen. It has the effect of raising volumetric efficiency because there is a lot less air (which is 80% nitrogen) in the cylinder allowing for a lot more reactants in the same space. That and it's also an extremely high octane fuel etc.

[@Technotranceism]

My thoughts exactly, I would imagine that the plugs and ignition system, aren't very happy!

[@andersjjensen]

From what I can read nitromethane has a lower octane rating than ethanol, but because you comparatively hose the engine with it the evaporative cooling makes up for a lot of that.

[@chauvinemmons]

Yes nitro has oxygen as part of the molecule with alcohol it may burn nitro it's not meant to provide oxygen mostly goes out the exhaust pipe nitro decomposers much like dynamite it's actually closer kin to TNT. Where do you get the real power issue fill the cylinder with more fuel than can exist at top dead center under massive heat and pressure it decomposes turning all that liquid into a gas that is your power if you have about 65 degrees of Mag lead 4 degrees 8 degrees 12 degrees of timing is not going to help. Run a hundred percent with about a 9 gallon pump you're liable to melt your Pistons if you had a real mechanical pump putting 20 25 gal a minute in and 40-60 degrees timing and 85 percent nitro in the the tank Now try that.

He said it was the only way he could afford to play w/ his toy. Back then, a 55 gal drum of mid-temp was about $100; nitro was right at $1000. The temp is drying rate when used cprrectly, for thinning lacquer. We used it for years, 1 qt to 15 gal gas, to de-carbon '70's smog motors to eliminate carbon build-up dieseling. Have used it for 40 years as a bad gas start up additive, or a tired motor revitalizer. Never damaged anything w/ it.

[@rars0n]

For anyone who doesn't already know: nitro contains both the fuel component and the oxygen component. So the more you add to the mixture, the more power it makes because it's largely bringing the oxygen with it. I really love seeing you actually test this out on the dyno though. VERY interesting stuff!

[@paulsachs9983]

Our course youtube experiments turn to oxygenated fuels. Wait until they discover hydrazine and flak jackets 😂

[@JETZcorp]

In the 1960s, the Ramchargers drag racing team made up of Chrysler engineers started adding hydrazine to their fuel. The tech inspectors wondered why the tops of their pistons were turning green, and they made up some nonsense about dye and combustion analysis or some such. Eventually their supplier got curious and asked what sort of military aerospace project Chrysler were working on with the ultra-toxic hypergolic rocket fuel. When they explained that they were using it as an automotive racing fuel additive, the guy flipped his lid and said they were all lucky to be alive.

I'm guessing white trash will be running nitro race gas / methanol soon instead of the current setup with mass nos use. Really, i'm hoping it's a whole new vehicle, something odd to add to the fleet. I'd be mildly interested in seeing an old rwd volvo wagon burnout car running it's 5 cylinder on this until it blows it up. 😂

[@insane4wheeler1]

I watch engine masters so i can learn things. This is like an episode of engine masters. Very knowledgeable info. I may never use this info, BUT anytime you learn something new, it is worth it. Thank you

[@NitroGnome]

Finally!!! :D but now, small warning.... starting up or cranking engine with nitro in it may really make nasty explosion, even my small lawnmower engine got exploded so violently that there was pieces that gone trough plywood ceiling... so BE really cautious and safe with it... Greetings from fueller harley owner and mechanic...

[@chrisclark6788]

Cleet seems like the most busy person you’ll ever meet but has time to do this😂 all to you brother

[@halfshark101]

Legend has it, Nate broke the up arrow clean off on tuning

[@thehighlander1720]

Fun! A-lot of these guys when they play around with nitromethane forget or don't know when when this stuff is refined/created it's bonded to an oxygen molecule. So, as a fuel it brings it's own oxygen to the party; it's the reason it delivers so much power when injected, compressed and ignited. Had these guys known or remembered this and used much higher fuel pressure and a whole lot more volume they could have seen some much bigger nunbers. Of course doing so might have caused that engine to scatter itself all over that shop... yard sale! LMAO!

[@000001willy]

So the lesson to be learned from this is that should be used as the fuel for Mullet to move you into the five second range.

[@CGT80]

Yep, that is why mullet only makes 5000 hp and top fuel cars make 10000+ hp......it's funny how it matches their doubled number on this experiment.

[@clankyexpert8998]

Mullet has the engine and turbo to go 5s it’s just the tuning and suspension they’re gonna have to dial as they’re already pretty freaking close

[@CGT80]

@@clankyexpert8998 Mullet is also heavier than Tom Bailey's car, from what they have said, so it will be harder than it is for Tom to run 5 seconds.

Hell Yeah Brother 👍

[@vincentrobinette1507]

I love the smell of Nitro in the morning...It smells like VICTORY!! The next thing to do, is change the oil and filter, run the engine on gasoline for a few minutes, then change it again! Burning CH3NO2 (Nitromethane) produces water and nitrogen, which becomes nitric acid in the engine oil. Once oil goes from being dielectric (insulator) to electrolytic (conductive), it begins to cause corrosion and worse, galvanization between dissimilar metals within the engine. That attacks bearings and piston rings and their landings. Letting the engine sit with contaminated oil does more damage, than actually running the engine! When going back to gasoline, you might check the fuel map... Maybe a little less duty cycle on the injectors.😀😀

[@punisherii5209]

Hey Cleetus, just a thought I have. Your guys at the shop all have great video presence , seeing more of them working on our favorite cars would be awesome ..I miss the earlier days of the builds and repairs afterwards. They were some of the best shows around. I bet if you did a survey , you would find most of us loved those videos. Any one of those guys could do stand alone videos and add to the McFarland empire with more content

[@blownmouse]

Amazing power and torque out of a stock 5.3. Very cool test guys.

[@middletnpyro]

this might be the best episode of the month of freedom so far!

[@tonymayhew191]

On the last good pull you could see the tire start to distort from the torque when he first punches the loud pedal! Impressive guys! I was belly laughing when I saw that tire begging for mercy. 🤣

[@YlowX7]

Yeah, something to do with the shutter speed of the camera creates an illusion of the stokes spinning backwards. the effect is possible with the naked eye, but it's different.

The naturally aspirated torque per liter value is what is really incredible. Usually 90 lb ft per liter is the absolute max. Looks like you were up around 95 lb ft per liter. That is really good.

This is the type of Month of Freedom videos I've been waiting for!

[@fritzozuna654]

Great content! Maybe 25 yrs. ago a rodding mag. had an article about something the racers in the early 50's were doing that would double the power of a stock flathead Ford...for one race. Hydrozine! Blown rods were worth a big prize win. And while they could, they used actual ROCKETFUEL!!! Outlawed long ago. Maybe you could try some of that, but do your testing outside.

[@allseeingeyezz]

that stuff is incredibly toxic. that's why they don't use it.

[@tactical_potato81]

This was such a good episode and definitely not what I expected. I would love to see a Crown Vic with an eBay turbo and an upgraded fuel system with some of this

[@dan3162]

One of the top videos in years, solid work guys!!! Time to change the entire fleet to nitro

[@Fosterforged]

Laughed so hard when Sam shows up in a lab coat 🤣🤣

[@joedelgiorno6110]

[@joseacuna3239]

I mean, the amount of fuel being dumped into the engine to achieve this madness is incredible. No wonder why top fuel dragsters are so expensive to run (besides all the other variables)

[@Calango741]

Have you ever seen a video of how much Nitro is being just blasted into a top fuel engine? It's almost enough to hydro lock the engine. It only works because Nitro Methane has it's own Oxygen, so the air/fuel ratio doesn't have to be regulated anything at all like a gasoline engine.

[@llamacebu216]

Nitrogen is cheap Besides, everything used on the Cleetus channel is ad revenue. Which means nothing comes out of his pocket bc youtube is technically a "business".

[@johnc.hammersticks]

Stock 5.3 nitro tune, with some parts thrown at it having a pure nitro tune for the track would be killer. Those were huge gains!!!

[@Spadishking]

Yeah they were, I have stock 2001 GMC that's 314 hp with just an intake and exhaust, this made me realize the power the old iron block v8's can make. Although I can't afford nitro methane anytime soon it's still cool to see the capabilities of these old engines

[@johnathanromero3944]

I doubt the engine would last a full trip down the track with that high of a mixture of nitromethane. If it did the plugs would probably be melted and the rings would probably be vaporized lol it would be cool to see a SM nitro small block thrown in!!

[@dalegnodle]

But it would cost you a thousand bucks a run just for fuel!

[@chadkent1241]

​@@johnathanromero3944 at this hp level, that's not an issue. Plugs will be fine. It's the heat generated from 11,000 hp that melts parts in a TF engine.

[@KittyMorgan-m4p]

I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.

[@Randomactivities2.0]

I used to put r.c. car 80/20 nitro in my 87 mr2 mk11. Also, a homemade brown gas generator can give decent gains. It's super easy to make and adds alot of umph when the reostat is tuned in properly. Throttle body injection works best for tuning the hho generator. Easy to build hard to get proper ratios tho.

[@rydplrs71]

James holding his heart looking at over 450hp was like a woman looking at an engagement ring. Pure love. There’s still 5 minutes left, so hopefully there’s a nitrous bottle on the way. Edit: next episode

[@lobsterbisque7567]

Now you know how a nitro injected A/FD can run straight up with a blown alcohol dragster. They make torque almost like a EV. Right off the hit.

[@P-J-W-777]

You know that was over 500 horsepower to the flywheel on a stock motor. Now see how much more horsepower a stock 5.0 will make.

[@warrenmichael918]

pretty expensive motor to play fuel games with. I wonder what Steve would say if they asked him if it can go on nitro?

[@Notarobot310]

With the SMX things for Mullet are about to seriously change considering what Tom Bailey and Steve Morris are going through trying to that much power from tearing up everything it's sending to the limit. However as far as this truck, it needs to be a Leroy type of creation so bend some pipe and send it.

[@mjay6245]

Mullet already makes too much power for small tire setup. Cleetus isn't anywhere near the 5000HP max, so no need to blow it up on nitro.

[@Bobthebuilder.69]

@@warrenmichael918 nitro engines don't normally live a long life, Top Fuel dragsters do a burnout and a 1000 ft pass, then it's time for a rebuild.
