See Thru Engine on New Turbo Got Boost? (Nitro & Dyno)


I’m already on episode 6 with this thing and
that is pretty unbelievable check out the series playlist if you haven’t
seen the previous episodes I’m going to be picking up where I left off
in episode 5 because this thing was just starting to make
boost I think the only thing that we were missing
to make more boost is more fuel This is running nitromethane not gasoline Which behaves a little bit differently in
a turbocharged application So yeah let’s see if we can make some boost One thing I want to change this time around
is the way it’s mounted We’re just going to take a dolly some two-by-fours A base screw that all together Drill holes into the concrete floor And I think that is going to work so I’m going to be using gravity as my fuel
pump here Overcome any boost pressure that we make during
this run This is going to be my regulation orifice And it’s also going to be a good indicator
of how much boost pressure we are making Because as the boost pressure increases the
fuel flow in that little eye dropper There it is right there is going to slow down So we’re all set we have our nitro coming
from our fuel tank like before We have our extra nitro using it kind of like
nitrous with this valve I’m going to start it up on nitro through
the carburetor give it full throttle And then open this valve right here just like
that And then we’ll see the nitro start flowing it’s already pouring out of the carburetor Okay start opening the valve a little Whoa too much too much too much Let it get some pressure hold on It’s running yeah it’s running I don’t know how much power it made but it
ran I didn’t hear the turbo spool though That run was very uneventful not really impressive It made 4.5 horsepower on turbo and nitromethane About the same as the previous episode So I’m going to try one more time See if we can get some more power out of it
on this setup but more importantly I want to see if we can
get some boost out of this turbo All right I heard it start spooling and probably
making boost the one thing I forgot to do is install a
boost gauge How are we going to see if it’s making boost
if there is no boost gauge Let’s run it again and see what happens That last run went pretty good And the engine started making some type of
knocking sound And while that may not be good In my opinion change is always good At least we made some type of progress here And it made about 4.4 horsepower not really
impressive And the boost gauge was bouncing around just
a little bit Now for this next run I’m going to remove
the exhaust manifold completely Because that is kind of a restriction And my idea behind making this exhaust manifold
in the first place Was I thought it would create kind of like
a flow in there and I don’t know increase the performance but it may have actually hurt the performance Let’s run it without the exhaust manifold
and see what happens one thing I want to do before this next run
is check the oil real fast One thing I’m curious about whoa What’s that that doesn’t look good I wonder what that is It doesn’t really smell like nitromethane
it just smells like oil I wonder if maybe the piston rings are broken
or something I don’t know I’m going to change the oil and run it again anyway yeah that’s what I’m
going to do Look at all that metal Alright oil is full I heard the turbo spool for sure that time Let’s look at the high speed camera and see
if it made boost I’m tired of this set up already I think the real restriction now is going
to be the carburetor Like everybody said previously in the Comments I’m going to remove this carburetor completely
the whole thing And that is the inside of our turbo It’s going to be full throttle all the time And I’m just going to spray the nitromethane
into the turbo And just kind of listen to it and tune it
as we go I mean theoretically it should work Yeah let’s see if it actually works All right ready to go oh just one more thing my kill switch in case I need to shut this
engine off In an emergency or it runs away or something
happens I’m going to get this ball and stick it right
into the intake of the turbo cut the air to the engine and yeah it should
work right I have it all in place ready to go My Killswitch My mechanical fuel injection system And yeah we’re ready let’s see what happens I’m going to call this mechanical fuel injection
wide open throttle The sky is the limit let’s see what happens It looks like that was the longest run in
history of this engine I’ve never seen this engine run that long And it looks like it’s overheating like heck Now we know why they use mechanical fuel injection
on the top fuel dragsters Because it’s definitely reliable for sure that was really interesting that it ran on
my mechanical fuel injection sprayer system What I want to do now is Mount is exhaust
manifold back on Quiet this down so we can hear the turbo spooling I love that sound I’m going to give it one more shot the way
it is right now And then do something completely different All right that was a pretty good run Yeah I think that’s all we got Whatever boost we got out of it right now I heard the turbo spooling That’s the most horsepower its going to make If it made boost it made boost and looking at the high-speed footage I see
it made about 2 pounds of boost Which isn’t much but it did make boost can you imagine with that little turbo what
this thing is going to do I’m going to go with a different set up all
together But this was fun Let’s do the math real quick Once I started applying more load it started
eating up more nitromethane And I just went with it so if we do the math That’s going to be 7.2 horsepower that’s what
I’m talking about Okay I just refilled this bottle right now
and on that last run It used 45 oz of nitromethane and it was a
2-minute run 45 Oz I thought that was a pretty impressive number For this next set up I’m going to be using
this turbo right here Which is far as I know is the smallest turbo
that they make To give you an example of size difference
this turbo right here is 22 mm And this one is 27 mm now that you saw which turbo I’m going to
use time for me to build it I’m all done with the new set up the turbo
is mounted The intake pipe is mounted And I’m just going to leave it without the
carburetor for now And do a quick test run with the stock head
and do what I did before Spraying the nitromethane right into the turbocharger
and see what it does First things first before you starting any
new engine or turbocharger Make sure you add some oil all right that was a test run with the turbo
properly set up and the stock head I think it did pretty well looking at the high-speed footage we can see
it made a couple of pounds of boost And again it’s freewheeling there is no load
I didn’t apply the dyno brake Did you see that RPM I had to cut it short and put the ball in
there I didn’t want it to run away But yeah I’m going to do this run one more
time This time with the see-through head and let’s
see what happens All right that was a pretty good run I think we might have lost compression or
something happened Because it just died out but yeah that looked
pretty good Wow it cleaned that head up alright let’s see what happened there why
it shut off That’s what happened look at that Looks like our little screw the retaining
nut for my electrode Must-have vibrated loose I don’t know if it’s the nitromethane or the
RPM or the heat or what I’ve never seen this before but if you look
at the see-through It’s actually like polished wow that’s pretty
cool If that electrode didn’t break off if that
didn’t happen I bet you we could have burned through this
whole thing This time I’m going to run it one more time
with the new see-through head And I’m just going to go for gold I’m just going to try to blow this thing up And I have a wider shot on the high speed
camera Hopefully we’ll see some Carnage and something
blow I’m not sure but that’s the goal to make it
blow That run was probably my favorite run of all
of them This thing hit 7400 RPM I didn’t see what
the boost was Because I was so excited that this thing hit
7400 RPM With the see-through head with boost So I’m going to do another run This time with the stock head on And my goals have changed just a little This time my goal is going to be to make as
much boost And as much horsepower as possible with the
stock head I’m going to put as much nitromethane to keep
the mixture Right where I can hear it should be And get as much resistance on the dyno and
see what happens I think this is going to be awesome I don’t know I have a bunch of stuff coming
out of the intake of the turbo I just don’t think this turbo is as good but Yeah I don’t no I wasn’t really impressed Let’s look at the footage and see what it
looked like That run was just okay Not really what I expected I wanted to see
more RPM Like the previous run with the see-through
head I can’t figure that out I would have thought
with this stock head We would have more efficiency and just better
flow and we would have got more RPM but that didn’t
happen I also think that this turbocharger design Is not as good as the Mercedes turbocharger The impeller design is probably a little different Because with the larger turbo I can hear it’s
spooling more But it was making less boost pressure And once it did start making some boost pressure it didn’t perform like I thought it was going
to So I’m going to do one more run even though
I don’t want to I want to end this video here but I am determined to make some boost pressure with this turbo I know it has to make some boost pressure What I’m going to do next is I’m going to
drill a hole Into the intake tube And use that same sprayer that I was using Run a hose from the intake tube to the sprayer to create a sort of mechanical fuel injection
system That way we are injecting fuel after the turbo
charger not before my gut feeling is that when I’m spraying the
fuel into the turbocharger Right when it’s starting to spool up The stream of fuel is hitting that compressor
wheel slowing it down And then interfering with that spool up So I’m going to try it one more time with
this mechanical fuel injection system And let’s see what happens I have a feeling that it’s going to work oh
yeah Wow that sounded good That was good we did about 3 pounds of boost
7.5 foot pounds of torque At about 4200 RPM and if I do the math real
quick That is about 6 horsepower So it’s not the most horsepower it’s made But yeah it did pretty good It did what I wanted it to do we can move
on I have AMP EFI engine management system That I am going to hook up to this engine
for the next episode I’m going to try to do a full out fuel injection
system With all of the sensors And that way we can control the boost The mixture the timing the whole nine yards That’s it see you in the next episode Which is going to be this engine and hopefully
it’s the last I know I said that like three times hopefully
this is the last See you guys next time Let me know what you think in the comments

  1. you should probably let the engine rev up to 6000 before applying the break, so it will have a lot of boost at that point. It might make more HP that way. Also, you are spraying way too much fuel in there, the mixture is too rich and it won't burn as good as it could.

  2. You need a to have a some thing like a air tank in line between the turbo and cylinder head, becouse it's a single piston engine compared to an engine with more cylinder, so you need to have "boost" waiting to enter. Becouse when the exhaust value closes the turbo turbine side has no flow to it to keep it spooling, so if you can make an in line tank on the compressor side you can make more boost you could make 8psi if not more becouse you have it waiting

  3. I am believe that if you fabricated an intake runner (simple pipe into the turbo, spray a steady stream of high pressure fuel and compressed air MASSIVE POWER AND CONSISTENTLY, add on an 02 ( wideband )sensor and gauge for long term power!

  4. Why don't you do a full 20 horsepower build with a Predator 212 then add in the nitro methane and the turbo to it.

  5. Why? Why not?
    Ah or yeah my mower engine failed.
    OK, So what happend
    Ah, under 6pi boost running nitro methanol it just stopped man, I don't know what happened it just stopped.

  6. Q [email protected] muito legal mesmo!!!!! Tenho um motor desses na ordenhadeira aq em casa para quando acaba a energia ai eu logo ele na bomba de vácuo da ordenha aí não é preciso retirar o leite das vacas na mão e sim com a ordenhadeira normalmente……

  7. Do a bi turbo setup , make the smaller turbo power the bigger turbo and the output of the bigger turbo into the intake

  8. I turbocharged a 5hp Briggs in. Auto shop class 20 years ago. I learned a turbocharged one cylinder engine needs a chamber. Or intercooler(not just a open tube ) to supply boost when the turbo isn't making boost for 3 storks if I remember correctly the chamber needs to hold 4x the engines cc.

  9. Single cylinder turbo engines run best with what's called an air capacitor on the intake side between the turbo and intake valve. The air capacitor size is between 4 and 5 times the size of the engine, so a 100cc engine would need a air capacitor between 400 and 500cc's. You can find plenty of info on Google. I searched "air capacitor for single cylinder turbo engines" and plenty of info including a paper written by the MIT department of mechanical engineering, and there are also several videos on YouTube showing people making air capacitors. Love your videos, keep up the good work

  10. My algorithm is the fuel to air is incompatible to energize at the maximal level. I could develop much better system. As you can too. I understand last minute stuff! Work bugs out. Can you check for head gasket leakage.? 3times i had head gasket leaks. I bet u 100$ thats it…………

  11. du duutoto much fuel not enough fueltoooooooo not shakey. an evenflow of fuel would have helped pressure tank with some regulation for the fuel would have worked wonders with regulation 8.5 hp at9 or 10 out and shaboomwent the rod. having fun is what it is all about eheheeheheheh.that milky shit in the oil was water and a little excess fuel. alchi always makes water below the piston.

  12. Cool but I have to say. It sounded like crap. Might need to get the base engine running correctly then add one thing at a time to it. Might make some power then

  13. Cool vid!
    I just made a vid where I run a JB Weld crank journal, and I reached under the mower deck to move it sideways on the vid. (I never run a blade on my lawnmower engines on my vids, so I was safe). However, some people are kind of freaking about it.
    Could you make a vid with hot dogs in a glove showing why you NEVER reach under a running pushmower!? It would be a Public Safety vid!
    I also have a vid idea for you that I am 100% sure will go HUGE, please contact me about.
    Miles

  14. Just curious if you did a compression test with both heads on the motor, I'm will to get the see thru head has the slightly higher compression?

  15. the turbo is massive compared to the size of the engine you will never get much boost and in a real application would have excessive lag. The project is pretty cool though it's too bad they don't make really small turbos

  16. You should try a mikuni carb I have a 26mm on my 5hp briggs it makes around 8.5hp runs mint and it took the top speed of my go kart from 41 to 55mph

  17. How this dude is still alive is a mystery.
    His still having 9 fingers and doing this kinda stuff is amazing.
    But his still being alive and still having at least 9 fingers while doing this kinda stuff is Absolutely Incredible !!!

    In the next episode he gargles peanut butter while running before wrapping himself in bloody seal blubber and swimming with great white sharks !

    The last sound this guy will ever make will be
    " Kaboom " !

  18. Why not use the stock carb on gasoline feeding into the compressor? Get the baseline with a good plug reading. Once you have the baseline, try things one at a time to compare 'a to b'. You may need more lead on the ignition. BTW- the schmooze contaminating the lubricant oil is the nitro leaking past the rings. Every NHRA fuel-class engine oil looks like that after a run.
