Hot Rod Supercharged Briggs and Stratton 5hp

[TheCoolmandarek]

lets see the thing run man ya caNT HAVE A video without the vroom

[sweetcarguy]

Dont let the ney sayers get to ya. They said the same crap before racing lawnmowers around a track @ 100mph was popular. These "engine builders" boasting 15hp builds lets you know right off the bat there clueless. Ive seen 50hp and better. Stick with it, that Linn Tech is a good school. I have a buddy that went through there auto program. Have you thought about mutiplying torque to the SC? Try using mutiple pullies or a mutiple gearset.

[rotax7804]

How about great job ! Who cares if it really works, you tried and still are. Most of these "couch potatos" couldn't due half of what you have done. Keep trying you will get it.

[Rat69Fink]

macks no sence

[rlckwd]

so after all that work how much power you making? 15?

[ridinhonda4life]

what kinda supercharger u got? lookin for one to put on my mini chopper im building

[quezzers03]

@ridinhonda4life i would not if i were you i had majour problems with the one i built it ran like crap and was all new parts/engine and would cost you at least 400 to get it running properley

[quezzers03]

i just started this simalar motor with simalar charger and works great and has 6 pounds of boost P.S. anybody that reads this whatever you do, DO NOT USE RUBBER HEATER HOSE

[26yearstoorion]

One more comment, USE A TWIN CYLINDER BRIGGS with that turbo next time (MUCH better results :-)

[26yearstoorion]

Oh... it won't last very long but sure is fun shredding those cheap-o clutches :-p

[26yearstoorion]

Geeze, Turbocharging & supercharging these single cylinder engines is pretty much a waste of time as the RPM's necessary to spin that turbo on a singles exuast pulse isn't there & the mechanical drag of the supercharger pretty much negates the gains at such a low RPM (35 years of building motors here) Cool though, try NOS or removing the head gasket to increase the comp, using a thin sheet of aluminum (cut your own) diaphram carb and use alcohol (start on gas) = 12-15 HP out of a std 5HP :-)

[quezzers03]

@longjonsilvrr nither it might lower it but really depends on how much boost is on it if its olny 5 psi probaly not but if your doing what im doing as in putting 10 psi to it and reving the crap outta it then it might last about 4to5 years

[quezzers03]

@Dnaudio12 he said it on the discription its a smog pump

[quezzers03]

im doing this to a nine horse with 20 pounds of tq im just wondering could i make like 10 pounds of boost does that sound right ive got mine all setup just waiting to hear back from a buddy with some flanges

[quezzers03]

@ohyrag obviouslley not

[quezzers03]

@roro879 not nessasairly if it is a new piston, rings and rod then he will be fine and the rod should be just fine because ive pulled apart one and seen the rod all id do is gride the casting lines away they say that'll make it stronger cause then theres nowhere for a crack to start

[hakera19973]

are you sure this is 5hp? looks like 20hp

[quezzers03]

@hakera19973 lol true

[quezzers03]

how do you start it

[quezzers03]

what is the name of the video of you trying to start it

[Dnaudio12]

What kind of supercharger is that, it looks like a air conditioner compressor

[ohyrag]

So after you supercharged it the horsepower is up to 5?

[rklos87]

@kothb123. No offense there buddy but it's obvious you do not have much knowledge of forced induction, so please refrain from your half ass input. He made a super charger out of what looks to be a belt driven smog pump. Pretty dope idea man!

[PFCPalmreuter]

maybe run the carb right off of block. i think your losing too much fuel inside all the pipes and sc. just put an air filter where you have the carb and run the charge pipe onto the carb.

[DialedBMX]

This is so cool, bravo, this is very inspiring. How long did this take?

[craigsmithx]

You are awesome. Your root looks like a smog pump!

[cammingchevy]

Smog pump? Did it make any psi

[kothb123]

yes yes i know how a super charger works but if u take a HUGE super charger from say a camero and i put it on a 5 hp engin your not getting the right amout of psi, which is critical for optima performance

[likayouful]

5 Stars Short Clip

[kothb123]

is that a scale turbo ? if not then ur not going to acomplish much

[turbodiesel3500]

@kothb123 Its a supercharger, runs off the crank. a turbo runs off exhaust.

[roro879]

You need a wiesco piston,rod,and bearing,to handle the extra stress

[TommyGullo]

how much boost did you get because im thinking of doing this to a kabota d 722

[724x4acchevy]

@TommyGullo I had a pressure gauge on it and for the short time it ran, i saw 3-4psi of boost. I only had it running for a few minutes and never changed to the overdrive pulleys.

[TommyGullo]

@724x4acchevy I got it going and put a boost gauge on it and was getting 10 psi at idle and at full 15psi thanks for the idea!

[Twankiejones]

@TommyGullo just put a turbo on it man

[charger19691]

Very nice machining work and engineering of this little engine. When you get the bugs worked out you will have a little screamer on your hands!

[Anniesmycat]

run it!

[outdoorsman1k]

You need to post a video of it running

[724x4acchevy]

@outdoorsman1k

There's a short 40 second video of me trying to get it running on here. The theory works and is proven, i needed to use a different style carburetor than the diaphragm style tillotson. Went to a float style carb and eventually got it to run consistently. Unfortunately i don't have any videos of that.

[stopglobalswarming]

@724x4acchevy Sent you a link to a very versatile carb from a moped that works on these motors.

[stopglobalswarming]

I have heard of go-kart builders using Ford F150 smog pumps, and supposedly it works really good but if it over-revs, it blows the head gaskets. good luck with your project.

[331hemi]

who are you on the hamb?

[724x4acchevy]

@331hemi Ratty55

[331hemi]

@724x4acchevy

i saw your hat in the picture.im bulletproof1

[NickyFlores]

@724x4acchevy .. I shoulda guessed you'd be a HAMBer.

[longjonsilvrr]

do puting smog pumps or Supercharging an engine like this, extend or lower the lifespan of the engine? or neither

[goodmechanic]

@longjonsilvrr Whenever you install power adders to an engine such as turbos, Noz, or superchargers, you increase the stress on the engine.

[JamieMcClanahan]

@goodmechanic  DUUHH

[Ibringthetruth1]

You didn't show it working.

[hayden12w3]

Nice Work! I hate that same engine, and a few smog pumps from old suburbans! I just might try this out myself.

[dext1991]

i need to know somthing =) - why? O,o

[MalliganTheUFO]

Is that a vane type compressor, if so, what is it off??

[TrackEmDownKennels]

How much does something like that cost?

[superpizzaboy7]

would it be possible to run an alternator or fuel pump on the same belt at the same time?

[shinyfuzzy]

you're lucky to have access to tools like these

[24preacherboy]

If you run propane instead of gas you wont have the runner problem. Plus propane is 110 octaine. It saves a lot of headach when it comes to fuel delivery.  I am going to use a couple of smog pumps on a 4cyl military 4a032 engine (looks like a small vw engine). It will run a propane carb. Let me know if your interested. I will post vids.

[JcXtreme72]

@24preacherboy I'm very interested in seeing that setup

[AlternativePowerMan]

Keep it up!! Looking forward to see it running.

[ColonelK0rn1]

Nice machine work. I was admiring the carb work as well.

[jasongiddensviper478]

Well done! Thank you for sharing.

[colbycous01]

bad ass,, what do you figure the hp is at wot? 5+5 more, or less,,, or maybe even more? to bad you cant get him to idle down. maybe if you put in a propane injection at the head to turn on just at idle?

[muhammadisasissy]

VERY Cool!!! You doing your own machine work?

[724x4acchevy]

@muhammadisasissy Yes, i'm a CNC machinist.

[CAPTIVEPULSEMAKER]

@724x4acchevy

...on the subject of forced induction....y'all should check out the supercharged two-stroke videos....other really cool ones (videos) would be Scuderi engine, Tour engine, and Jan Ridders' super chill Scuderi engineering model...you might want to catch my "CAPTIVE PULSE" / Panthera Supercharger X 13 also...it's a hydrogen fueled piston supercharged OHV two-stroke engine...The current videos were quickies. I'm working on some better video...

good work....Thomas

[billmorse]

Why couldn't we see it run ?!?

[DeanLyman]

Your my hero.

[wmralder]

The simplest solution that I've seen to the pressurized carburetor is to put the whole carb in an air-tight box and pressurize the whole thing. You will probably have to pressurize the fuel too as in use a fuel pump or pressurize the fuel tank too. In the end the carb works with pressure differentials and as long as the "ambient" pressure is the same around the carb it should work.

[Compwhiz128]

GAWD DAMNIT! mills and lathes galore!

[dnl5649]

i did the same thing, i actually powered the engine by propane though. the old carb wouldnt give the engine enough gas to make it run so i drilled a hole in the carb and put a 1/4 inch copper tubing attached to a old torch on a propane tank. it worked okay, maybe 3 psi of boost, my smog pump was from the ford 400 cid in my mercury it was pretty badly worn out though. it wouldnt idle at all and it ran rough

[robby844]

ummm so you say youve seen alot of "fake" supered briggs but yet you used a smog pump?

[724x4acchevy]

@robby844

By "fake" I'm referring to a leaf blower duct taped to the carburetor. Most of the videos on here are of smog pumps forcing air through a carburetor that was designed to siphon gas up a pickup tube. If you force induction this style carburetor it will run very lean if at all. By putting the supercharger between the carb and the block, i'm able to keep it a pull through system and maintain vacuum behind the carb. It works more like a traditional roots style blower on a SBC chevy

[BigEsGarage]

@724x4acchevy A blow through system is possible if you keep the pressure equal, the bowl to the intake, the pressure differential in the ventury will still happen under boost. In some cases no re-jetting is needed.

Drag bikes using a wippel or a turbo, not set up as a draw through, do this all the time mostly, I believe, because of idling problems an quicker throttle response. Nice job on the fab, by the way.

[724x4acchevy]

@robby844 also, these smog pumps are without a doubt able to produce boost. I installed a pressure gauge on this setup and it was able to produce 5psi. Unfortunately my intake runners were way too long and my fuel mixture fell out of the air by the time it got to the cylinder. The only time I could get the mixture to stay in the air was at wide open throttle. It would not idle at all.

[robby844]

@724x4acchevy say what you want its still a fake super.

[muhammadisasissy]

@robby844 No, most smog pumps are nothing more or less than a vane supercharger or their design and function are the same.Unless the unit compresses the charge in the unit its self (as in Judson or Norman) it is not a true supercharger but a blower (like roots type or turbo-charger). No matter what you want to call the unit :supercharger (noun) , smog pump, or? it can still "supercharge" verb but, nothing "fake" about it.

[TheMitch1611]

how much extra hp do you think it gave it?

[ciclotronforever]

Wow!!

Absolutely wonderful!

[gokartmaster123]

wow nice job on the engine also i hope you have a billet racing rod in that cause those stock aluminum rods only handle 6100 and they still can throw a rod

[foxdmulder]

Now thats a lawn mower engine, in the words of Tim the tool man Taylor::

Uuuurrrrggghhhh uuuurgghh uuurhhg

[724x4acchevy]

Motor has been sold to Mike Clements

[gaspowerrules]

@724x4acchevy cool is it more hp and rpm put on a go cart

[the4xchamp]

Do you want to sell it ?

828-212-4664

[the4xchamp]

That is the nicest looking Billet Flywheel I have ever seen ! Mike Clements

S/C is very nice too !

[roboman79]

How do you start it??

[norcalbruce]

Its a good idea to put an air resavor on the intake to even out the air flow. The smog pump doesn't have a steady air flow it has a pulse to it. See hanson supercharger corp for pic its the big funnel looking thing. It also has a pop off valve incase of a backfire into the intake. I'm just about done building my own.

[mctim64]

Saw this on the HAMB cant wait to hear it run. Keep us posted.

[724x4acchevy]

When I get it done I will. It's still in the construction stage.

[SAGKFCASBOST1CSX]

cool are you going to make a vid of it running
