See Thru Engine on Turbo Nitro and Dyno (How much HP does it make?)

November 20, 2019


Welcome back to Warped perception. This is episode 5 of the see-through engine
series. If you haven’t seen any of the previous episodes. And you want to watch those first. They’re all in the series playlist. In chronological order. If not I’m going to jump right into it. And bring you up to speed. Now in the previous episode I try to blow
this engine up. By running nitromethane. With aggressive timing. And just pure RPM. And to my surprise the only thing that happened. Is that it blew a head gasket. now this is the engine with new head gaskets
installed. A new transparent head. Oh and I changed the oil. that’s how the oil looks from the last episode. Wow that’s strange it’s kind of like jelly. Look at that. I don’t know what that is. But that’s what we have left over from the
nitromethane blow-up attempt. There’s some metal shavings and stuff in there. But nothing really crazy. Now before anything I’m going to start this
engine up. And show you that it’s in perfect running
condition. Before moving on. That sucker has compression look at that. It’s vaporizing. all right as you can see
the engine is in perfect working condition. Even after all that abuse. Now that we know the engine runs. I’m going to up the ante and add nitromethane. Aggressive timing. A turbocharger. And last but not least a dyno. So we can measure the performance of the engine
every step of the way. And see which modification makes the biggest
difference. first thing I have to do build the dynamometer. I decided to go low-tech and build a literal
brake Dyno. out of a basic disc brake kit. Some creativity. And a bit of Machining. I think my Dyno design. Is going to make it really easy for anybody
to understand. What horsepower is. And how it’s measured. This Dyno is also going to allow me to load
the engine. As well as track the horsepower output. Through each modification. To see which one is making the biggest difference. So the brake Dyno is installed. And like I said before. This is a literal brake Dyno. so I am literally
going to be measuring how much brake horsepower this engine is making. And if you’re not familiar with what horsepower
is. Horsepower is work over time. And 1 horsepower equals lifting 33000 lb. A distance of 1 foot. In 1 minute. to calculate the horsepower. We need to know how many foot pounds of torque
it’s producing. Now 1 foot pound of torqueperiod is created
by one pound of force. Acting at a perpendicular distance of 1 foot
from the Pivot Point. The Pivot Point here is our crankshaft. But in this case the distance from the center
point of that shaft. To this pin up here. Is exactly 6 inches. come up with since we have 6 in whatever measurement
we come up with. Will just divide that in half. And that will be how many foot pounds the
brake is generating. and last but not least the way with that we’re going to apply pressure
to the brake rotor. Is with this master cylinder right here. And the way this works is I kind of rig this
up. So we can turn it And lock it into each position. a place your bets right now is that how much
horsepower does engine can make. Because we’re about to see. I’m going to the control the throttle. While Diana gradually increases the master
cylinder pressure. Increasing the load on the engine. Until we get that sweet spot. and we’re at
the maximum amount of torque that this engine will produce. Oh no the head cracked. That was a pretty good run. Especially considering that we don’t have
a proper spark plug installed in the engine. I calculated about 2.5 horsepower. And about five foot pounds of torque. it looks like the load does make a big difference. Because this right here is the first time
I have ever cracked the head. And there’s even a little tiny pieces of glass
inside the engine cylinder look at that. next thing I’m going to do is remove the transparent
head. And mount the stock head in its place. and this is going to be a great comparison
between the make-do spark plug in the transparent cylinder head. And a proper spark plug and proper compression
with the stock cylinder head. Let’s run it ready to go. Stock head gasoline let’s see how much power
it makes. Okay that was a great run. Now it’s time for us to calculate how much
horsepower the engine made. And unfortunately I forgot to install the
tachometer. I decided to pull the engine back into the
garage. Install the tachometer that I forgot to install
in that previous run. And do one more run on gasoline with an accurate
RPM measurement. To get a good Baseline on what this engine
is making stock on gasoline. Then I’m going to move on to the nitromethane.
this is a tachometer that I’m going to be using for this episode. And I don’t know about you but I like when
I see a product being used in a real situation. Because if I buy it I know what to expect. In this case is going to get used and abused. And if it fails it’s going to be on camera. And if it doesn’t you know it’s good. So if you’re interested in buying this tachometer. I put a link in the description below because
I see a lot of cool uses for this. Including this one. Tachometer is installed and it looks fantastic. Ready to do our first accurate Baseline run
on gasoline. Alright that’s our background. Run number 1 accurate Baseline gasoline. Alright let’s see how much power this makes. alright so apparently. I didn’t account for this screw vibrating
loose inside of the scale. I’m going to put the scale back together and
do one more run. It’s always something. I’m just going to get some red Loctite and
fill up this screw. Put this back together. I definitely picked the right scale. Because this thing went right back together
again. Hopefully our scale doesn’t break this time. Ready baby. so that right there is almost exactly 9 foot
pounds divided by 2. Which is 4.5 foot pounds x 3600 RPM on the money. Which equals 16200 divided by 5252. which
equals 3.084 horsepower. That’s pretty amazing that this thing after
all this abuse is still making the rated horsepower. Time for the Nitromethane. I just have to change a timing but Nitro in
the tank and ready to go. Okay so that was a fantastic run pretty entertaining. We’re going to calculate the horsepower real
quick. We were at 4000 RPM. we’re going to multiply
that by our foot pounds of torque. Which in this case is 14 divided by 2 equals 7, equals 28000
and we’re going to divide that by 5252 to get our horsepower number. Which is 5.33 horsepower on nitromethane. That was pretty impressive 5.33 horsepower
on nitromethane. With just a little bit more timing. And I opened up the needle for the carburetor
all the way until it was almost falling out. To get as much Nitro in there as possible. So for this next test I’m going to take the
sequential turbo charger. Off of an SL 65 and modify it to fit on this
3 horsepower engine. okay I have the turbo all installed on the
Briggs. I mean it looks like something I haven’t ever
seen before. I’ve always wanted to put a turbo on one of
these small engines. And I just never did. But now it’s done. I put a spring on the wastegate here to keep
it closed. Because I’m hoping to build some boost. I put a viewing window here on the intake. The turbo is being lubricated by this Loop
tube. The only thing I don’t like about the way
that this is set up. Is that I had to use a wet system. Which means I have the carburetor mounted
to the turbocharger. And the turbocharger is pulling in the air-fuel
mixture. Compressing it. And then forcing it into the engine. I don’t like that because that’s kind of how
the first forced induction cars were set up with this wet system. And there’s a lot of problems with this but
I think it’s going to do for this. And now that the turbo is mounted modified
and ready to go. Let’s see what the engine does and how much
horsepower it makes On turbo and nitromethane. Okay so that run was kind of disappointing. We maxed out at about 6 foot pounds of torque
at 3500 RPM. Or actually 3 foot pounds because we need
to divide that in half. So only 3 foot pounds at 3, 500 RPM. no wonder
why they don’t use the wet system any more for turbocharged vehicles. It made last power than the naturally-aspirated
setup. so what I’m going to do is I’m going to try
one more time. Tune it a little bit and give it as much fuel
as possible and see what it does. Hopefully it makes more horsepower else its
going to be really disappointing. Oh there goes I think it made more power. I heard the turbo start spooling up and making
some boost. Did you hear it it went woohoo. so that got me excited I heard the turbo start
spooling up and it was like woohoo making boost. I don’t know where all that oil burning came
from. It could have been from the bearing in the
turbocharger or from the piston rings. maybe the piston rings are getting messed
up. If you listen the engine is making kind of
a little creaking noise. So I don’t know what that is. But with this run it maxed out at about 7
foot pounds of torque at 3650 RPM. And I don’t know if it was that much better
then the naturally-aspirated nitromethane run. But let’s do the math real quick and we’ll
see. So we got 3650 RPM x 7 foot pounds of torque. Divide that by 5252 and that’s our horsepower,
so. the numbers don’t lie unfortunately it only
made 4.86 horsepower With the turbo on nitromethane. So that’s kind of disappointing I’m sure this
thing will make way more power. But I’m going to end this video right here. Because this thing is taking just way too
long. This was a lot of building and everything
else and it didn’t blow up. It didn’t make more horsepower than the nitromethane
alone but. yeah if you want to see another video on these
engine I’ll definitely do one. I’m thinking maybe just fix these problems
because. I’m sure that this thing has to be able to
make about 8 or 10 horsepower with the turbo That’s just my guess. I don’t know how I can get it to work maybe
at a fuel injector. Some type of engine management system maybe. I’m going to look around and see if there’s
a company that makes that. And maybe I’ll bring it up in another episode
it was kind of fun. So let me know what you think thanks for watching. Hopefully you enjoyed that long painful episode
and process I’m trying to get more power out of this engine. But I think I maxed it out I mean. Putting a Turbocharger and nitromethane and
timing on this 3 horsepower engine. it still didn’t blow up and that’s pretty
amazing. So tell me what you think thanks for watching
and see you next time. This is going to be so cool you know how many
people have wanted to see this thing Dynoed on nitromethane a lot.

  1. It makes sense why less power with a turbo. A turbo requires a certain percentage of engine power to function. In a vehicle with a normal size engine, that percentage of power is smaller. But in a small engine, that percentage of engine power becomes far more significant. This percentage negates the overall increase in power. Looks like it uses about 1 Hp. to run.

  2. Have you really got nothing better to do?
    Looks in mirror;
    "Have you really got nothing better to do?"

  3. Love all your videos… been subbed for about a year. In relation to this video… "Too Much turbo – Not enough engine" (insufficient exhaust air flow/volume/velocity & exhaust Heat)… Turbos Need Heat to spool up quicker, and one cylinder is not only insufficient in every way for That particular turbo, but too far away from its needed heat source. Great Video, just the same… love the content. PS: What you're labeling as a "wet system" in regards to the turbo/carb setup, is officially known as a "Draw-Through" system. Keep em coming!

  4. Shoulda used a smaller turbo. Will definitely make more power. Basically its like rob dahm putting a ship turbo in his rx7 is what you did with the turbo from the car

  5. you gotta remove the governor from the engine so you can really open her up and get a way higher rpm so it can try to build some boost

  6. You’re awesome man! Yes people gonna comment that too many user errors and this and that of course won’t work but I see the video as just a dude having fun and not editing out stuff only to make you look perfect. Life isn’t meant to be so serious. Id love to kick it in your workshop, have a couple beers and create crazy random projects lol

  7. This video is in incredible and you seem like an amazing mechanic/engineer. I do however disagree with your use of nitromethane.
    From chemistry lessons, nitromethane carries oxygen locked up in the molecule. So much so, you run about 8 times a much nitromethane through an engine compared to gasoline because the fuel/air mix is so much greater.
    To make proper use of the nitromethane, you need to greatly increase the jet size in the carburator.
    Nitromethane only makes about 1/3 of the power an equal amount of gasoline will, but you can burn 8 times as much through the same engine and volume of air. It's why a nitromethane dragster makes so much more power compared to alcohol or gas powered dragsters.
    A properly tuned carb you should be able to triple your max HP results.
    Even though you opened the needle jet up to allow more fuel flow. I still don't believe you was anywhere near the proper stolchiometric mix for nitromethane.

  8. Use a smaller turbo! That turbo is design for a 4 cylinder to spin it, with a much larger displacement. That engine hasn't the capacity to spool the turbo properly

  9. Wet vs dry boost; probably a very valid idea! As far as US production cars are concerned in the modern era, Studebaker used a carb box on their blown Golden Hawk in 1957, then starting in 1963, they used a special sealed AFB carb on their R2 engine, and reverted to the carb box with the higher boosted R3 and R5 engines. The latter ran over 200 MPH at Bonneville in 1964, all with a 5 liter engine. Pretty impressive for a stock bodied car at the time! They used basically box stock Paxton/McCulloch blowers. The R2 would make about 8 pounds of boost in bone stock condition, although some claimed more…but with all new parts I'm assuming. In a completely different situation, the 2 stroke Detroit Diesels all were supercharged, but later models offered turbos. In my own case, a Turbo 6V92 engine was speced at 350 HP at 1950 RPM. When the boost reached about 12 pounds, you could feel the difference. That was 552 cubic inches.

  10. Try a Paxton supercharger or any other blower setup. I can't wait to see it. Please try it. Superchargers are more efficient and reliable I think.

  11. And so became a story about burning different fuels to blow up a lawnmower engine to a story about what you can pimp your lawnmower with 😀

  12. Old briggs things run forever they're pretty badass it's pretty wild I enjoyed that video I'm a mechanic myself I like doing projects and s***

  13. Them engines run for ever are lawn mower engine is still going after ten years of fitting a corn flake box for a head gasket what i did years ago lol😂😂

  14. I noticed your missing a finger I had my left hand caught in a table saw and lost 3 fingers. How did you lose yours?

  15. Bruh why is he calculating the horsepower of the engine, when at 12:48 you can clearly a sticker in the engine that puts 3HP.

  16. Look at what the oil looks like on a Top Fuel car that runs nitromethane. It looks just like yours. It's the Nitro washing down the cylinder wall mixing with your oil.

  17. When he was a kid, he invented the 2 story gravity hydro bong! And was safe about it, he used pressure gauges and a burst valve

  18. With high rpm comes high crank case pressure, you need some way to evacuate the crankcase. Put vacuum on the crank case.
    when the pressure is equal to or greater than the cylinder pressure the rpm cant increase.

  19. Beside the issue of WAY to big of a turbo, I would be willing to bet that the turbo wasn't spooling because of the single exaust pulse hitting it only 1/4 of the run time. I would bet you could come up with a super charger by modifying the turbo and hooking it to the crank shaft, that would even out the pressure coming from the compressor during the run. The next step would be making a dry system, maybe from one of the mechanical fuel injector from systems from Go Power Sports. I bet it could be rigged up to be a blow through system? Also curious if you put a boost gauge on it to even see if it was building any boost at all?

  20. 1971, Bonneville, a guy used an air injection smog pump from a 454 Chevy to blow into the carb of a 125 Honda twin…made 8 lbs of boost driven 1:1.

  21. All your experiments , so to speak , are fantastic.
    I would like you to test Mazda 's " Wankel " engine with the clear plate you make.
    The engine would run on original gasoline , firs in medium and then higher rpm, so in real life – mode.
    So it would look like combustion , suction , exhaust , so all that is very controversial with this type of engine.
    I know , i was looking at the little " Wankel " engine .
    Please be kind and do an experiment like this.

  22. 🔵 I would be VERY concerned about tiny bits of glass that got down between the piston and the cylinder, without removing the piston and cleaning everything out you're probably going to end up getting scratched-up piston-rings and cylinder-head.

  23. Bro me ayudas en un problema del mismo motor ya no quiere arrancar la comprensión es de 40 tiene chispa y gasolina que puede ser ayuda!!!!!!!

  24. Dude you are wasting your time doing this. You're girlfriend or wife needs you talk you into stoping this nonsense. I'm guessing you don't have a good job or anything better to do. C'mon guy.. long painful episode is right.

  25. Can you please make a tutorial or give a link to a dynamometer like that. I want to start measuring the torque of my motorized bicycle engine. Thanks.

  26. apparently because a single cylinder engine only creates boost when it doesn't need it (exhaust stroke), you need a boost chamber to hold boost so that the boost is still available when it intakes.

  27. Just curious, wouldn't you have to give the enginea rather large upgrade to be able to do something like that? Like change the valve springs, the pushrods, the flywheel, and maybe even the Piston?

  28. Thats weird. Cuz when I drink nitro methane, I dont get more energetic. I just fart alot.
    I think my car feels the same when I pour Red Bull in the tank.
    J/K kids…dont pour red bull in your car.

  29. Back in the late 70s in high school, we had thee best industrial arts classes. Electronics, machine shop, wood shop, and power mechanics.
    Power mechanics (auto shop) was my fave. Our teacher was David Vaughn. A retired navy guy with a hot temper, but extremely cool and understanding. Just follow 3 rules. When he talks NOBODY else does. When its study time, its time to study, no fuck*ng off. And, if you ever even think about stealing anybody elses stuff, just leave.
    Outside of that, we spent most the time rebuilding lawnmower engines. The 1st one you did had to be a complete basic rebuild. No 1/2 assed job and no mods. After that, you could rebuild a Pratt Whitney if you had the time. But 3.5 Briggs and Strattons were all we had time left for. He had the tools, but if someone else was still working on their 1st engine, they had priority. And that usually ran the rest of the semester out.
    Another rule, which was kinda fun. Your engine block had to be royally spotless. Because he would inspect all your parts prior to reassembly, then he would give you a choice. Peanut butter or jelly. Then he would slap a glob of your choice on a part of your block of his chioce…bon apetite. Start lickin. Because, hey. You said it was clean.
    His temper almost got him fired a few times. He threw a block of wood at one of us and nailed the kid in the lip because he told him twice to "shut up, this is important". The rest of that hour not a soul even squeaked in their seat. At the end of the class he apologized. The kid he hit was kind of a rich spoiled brat and sniveled "my dads gonna sue". But he realized he was the one being out of line. Next day we were all back to normal. That class was like family. We even had a girl in it. Everybody loved mr. Vaughn, the coolest shop teacher ever.
    I saw him about15 yrs later at a Carls jr. I think he had cancer, but I dint ask what was wrong. That was the last i saw him.

  30. You cannot put wärtsilä boat engine turbo to car and hope that it makes more power. Need much more exhaust gas. Little engine cannot produce it. If turbo is right size no matter where carburetor is

  31. You got what's called oil dilution . the meth and alcohol and the high rpm cause the gases to escape past the rings and it goes into the oil. This is why oil is changed every run on high performance engines.

  32. Hi bro.. can you teach me how you timing that engine for nitro fuel coz I understand that it's not the same for gasoline fuel timing. Hopefully you can teach me.

  33. The smallest engines that can be turbocharged start at about 20 HP NA output, and use the GT06 turbo (smallest you can get)… Anything smaller than that, and you have to use a shaft-driven supercharger. There isn't enough exhaust gas to power the turbo.

  34. So you made some mathematical errors. Your lever arm is 6 in and you said it needed to be one foot. you divided by 2 and you were supposed to multiply by 2… your lever arm wasn't 2 feet. Then you would divide by two but since your lever arm is only half the length. you would multiply it…. it would create more torque at a foot of lever than it would have at 6 in. Also when your turbocharging a small single piston engine you need a boost box. a way for the turbo to generate air pressure. If it had more than one cylinder you wouldn't need a boost box on the intake and you need to use one of the small little turbo. there like a hundred bucks on eBay. Rhb31i think it is. Boostedboiz on YouTube have a shopping cart single cylinder turbo and they go into the details of why you have to have the Boost box or whatever you want to call it.
