RUBICON'S Nitrous BSR

[RUBICON]

Soon as I can get new pics small enough to attach I will send more

[Mike Bean]

Very Nice Rubicon. How long did it take you to build?

Where'd you get that gas tank? I ended up needing to relocate the tank on my Intek, replacing it with something like that would be awesome.

[RUBICON]

Well...initially about 3 months. I started with the purchase of the engine on ebay. I needed to design the motor mounting and stool relationship. I studied pics of all the BSR's I could see on the net to determine what the fundamential dimensions should be and which were optional. The design developed on paper ( AutoCad ) and a lot of dimensions and position relationships were established before fabrication. My intention was to design it to suit me and build it only once...That was not the case...the fun is in the design and fabrication...and then...improving...and adding...and reworking..etc.....I had a nice kart steering wheel..then a MOMO kart wheel ( red suede ) with anodized quick release...the 3 different steering shafts up to 3/4" solid SS to be stiff enough...Then a mountain bike alloy handlebar and stem for more control at speed..foot gas pedal then thumb throttle...billet foot brake....then handlebar hydraulic..a straight carbon steel exhaust...now a stainless / carbon fiber MUZZY with SS header....straight aluminum axle...now chromoly with differential....mechanical brake...now vented hydraulic disk on diff for equal braking...a hand shifter under the seat like an old style chopper...now a billet foot shifter for great wheelies in all 4 gears...tried rain tires for looks...went back to slicks...and last....a wet fogger Nitrous system...so...it seems to be "the journey"...not the destination...if you see what I mean
ps: all of the fabrication was done by me in my garage...and the tank is a piece of scrap aluminum tubing that I welded ends on and tabs and ports.....note* there is a guy selling party keg tanks on ebay...look cool...but pricey for what they are....If I could not tig I might do one of them....

Looks good man!!

[RUBICON]

Thanks for posting these...when I take pics I usually have the camera set for highest resolution...then this comes up and large files are a hassle.....

[monkey-1]

No prob, here are more:

[Mike Bean]

Very nice work! I am going to have to add a pic of that to the barstoolracersupply.com site.

Now lets see some video!

Ive got to say I like this one. BUT my friend you got some big ones!!!!! That thing has got to just shit and git! Nice work. Glenn

[RUBICON]

Thanks for the kind words...There are very few of "US" that have the abnormal brain activity to appreciate the stupidity of all this. I have been alone in the venture from the start...which is sad when the purpose for me is first to spend time ( and money ) being creative in design and fabrication details and skills....and no one sees the point....I keep saying..." IT IS THE JOURNEY...NOT THE DESTINATION"...AS EXAMPLE...Look @ what everglon is doing...and what he has to work with...I look each day just to see how creative he is in making up for not having a selection of parts and materials or tools....this is the best of what it is about....creating...problem solving..and then....then...showcasing the result...
On a side note....my other interest is wagons...not too unlike studmonkey's...I saw the "daddy" of his many years ago...way before any following...look back @ Ed " BIG DADDY" Roth's ( the father of " RATFINK")creation called WagonMiester...and you will see that he was the first with the identical theme...well...I attend car swap meets and shows where wagons are the shopping cart of choice...and the common interest there is in custom wagons of a very wide range of materials, skill, creativity, ingenuity, and cost...I take pics of all of them I see...and I visit a short while with all that will talk about theirs...In some ways I may have raised the bar in Charlotte Motor Speedway's Autofair and Daytona's Turkey Run....but I see a few new ones every Spring and Fall...getting more crazy...if the pic is not too big I will attach....THANKS GUYS

[monkey-1]

Awesome! I love wagons too and have a couple of more ideas floating around that I want to get to some day. If you have any other wagon pics, post them so we can all see them!!

[elvergon]

iI might add that your barstool is the best one ive ever seen. Im so honored by your words rubi, its nice to have fellas and people helping me out with such experience as yours. Someday ill hope we can meet each other. I agree with you too, its the problem solving and the creation what makes it being what it is.

I still want some videos of your barstool bro. Hope you can get some, especially using that insane nitrous. Once again thanks bro and hope everything goes good for you.

First of all WICKED stool...Second I enjoy reading your input in this forum. I'm sure you have been asked this before and I just haven't read that thread yet but did you piece that NOS kit together or does it have a specific application. Not sure I need that on my stool but I've got to hand it to you it sure looks cool.

Really not sure how I managed to post this twice....But I'm not sure how to erase it

[altrego30]

Not sure if I said this befor, But Rubicns BSR, looks like an awsome machine, did you ever name it?

[RUBICON]

Thanks CanadianKid....after several weeks of research on the Net I was not able to find any real info on small displacement applications...I was originally inspired by the infamous nitrous GO-Ped and the Trans Am drag race video....when I found a site on gassing a radio controlled scale off road race truck...I figured it was not "ROCKET SCIENCE"...so I compared all the similarities and did my own.....I got lucky with my jet sizing...It is a "wet" system that combines 5psi fuel with Nitrous through a fogger nozzle in the intake manafold...This assures an adequate amount of fuel so the combustion is not too lean....it makes a real loud scream when the nitrous hits.....There has been only one other person that has attempted it ..but I have not heard progress since he bought his bottle....

Altrego30...no name yet...you will be @ sea when I run it at the local drag strip when it reopens in early March...plan on a one time event...lots of guys taking video and pics......just want that time slip to frame with a few of the best pics and have proof of such a crazy stunt.....When my son in law is on the SSBN TENNESSEE he says he stays so busy that time compresses...it must be different when underwater for 3 months at a time...in the summer they may get one " steel beach" when the boat surfaces for a barbeque and swim on deck ....I would rather run back and forth across a busy 6 lane than be on a flight deck....come home safe...and remember.....LIFE IS A JOURNEY...ENJOY THE RIDE!

Its not that I think it needs nitrous but I just can't get past the COOL factor. For anybody else that is interested there is a company www.boondockers.com (http://www.boondockers.com) that build a nitrous kit that uses a manifold to pressurize the vent lines of your carb with nos when you spray. Eliminating the need for a fuel pump. They claim to have had little or no engine problems. I purchased a system for my 660 Raptor and if it works out I will give my little beer buggy a kit to.

p.s. don't use their forum I asked a question close to 2 months ago and still no response

[moto1fast]

Hello Guys! I am putting my Nitrous on NOW and should know how it does in a day or two! I am going with the same jet sizes to start with as you Rubicon thanks for all the info on the NOS system. I am also putting a dual purge system on it for that Other part of COOL!:hot:

[Canadiankid]

Purge.....I hadn't thought of that.....way cool. You going to vent under the seat or were? Get pics, video and post please. Love it....a purge on a bar stool. Wicked

[moto1fast]

Hello, I am making a Smiley face like my avistar with a sign and he will be setting on the back top ring of my barstool with the purge comming out of his eyes. It will be a few days but I will post pics then! This thing is turning out to be one more thing and one more thing and one more thing LOL I Love it!!:thumb:

[RUBICON]

I looked at the Boondockers site..it was interesting...I did not drill deep enough...though I tried for a while...to get the gist of their theory of operation....I am convinced it works from the looks of the components and such...Where I was curious is in the fuel delivery. I wonder if they in some way pressurize the fuel bowl and get more volume that way?...I saw where you install a manometer to measure what looks like inlet ( not manafold) pressure ( like between the filter and the throttle slide)..and tune the nitrous jets to it.....All I have learned is that DRY systems that spray only Nitrous need the carb set rich to compensate and not run too lean....on a car with a small shot (50hp) the car will run ok a little rich....much over that will require more fuel that the carb alone cant control at lower throttle openings....and injected cars can run a little more dry because the ECM can compensate for the nitrous and add more fuel ( to a limit)...so...on such a small engine I would think that bigger fuel jets would make it run way too fat (not run at all)...to balance with the amount of nitrous...I was just cautious and added the pump to force fuel into the fogger nozzle.....I have friends ( that know nothing about small engines ) that run 500-600hp nitrous plate systems with dual stages to get over 1000hp....with that much money in a motor you don't want it to run too lean....it will run like hell...then explode....
ps: i have a spare polished 1lb bottle that I install on my wagon when I go to the car shows and such....so much of my stuff really works that I am often asked if it works on the wagon...( stupid question if you ask me ) but I guess that are still trying to understand the stuff that is real and get carried away...I tell them it doesn't function...but...it is real and is full...and that it is a spare for my BARSTOOL....that starts another interesting line of conversation...and when I see all the puzzled faces...I pull out the book of photos...nuf said...have fun

[Canadiankid]

I haven't installed my kit on the raptor yet, but you are bang on, the manifold that sprays nitrous into your air filter diverts some pressure to the carb bowls. I know a guy with this system and he doesn't run it rich. You have to rejet becuase you plug off the bowl vents but other than that it runs fine off the gas and pulls like a freight train on the gas. They don't build a kit for 160cc engine like my little honda but I think if I buy a few key parts and do a little reverse enginering on the system I bought for my quad I should bring a smile to my face.

[RUBICON]

You have the desire that takes you into uncharted water....take examples of what works...learn the theory....twist the application...experiment...and you become the first at a new application....when I say a remote controlled race truck...18" long...with a 2 stroke model airplane engine...a small canister of whipped cream gas ( nitrous oxide did you know? ) and a small brass needle valve on a servo....real nitrous on a engine that small...go figure.....

[Redrooster]

Awesome pictures of your awesome bsr...... What a beautiful machine....
Great work rubicon..... Hope you can post some video of you riding it doing some wheelies.....

[BAR-TAB]

looks like the underhood of a mitsubishi lol......same sized engine......... boatload of wires

[RUBICON]

Still looking for a way to post dragstrip videos...recorded on 8mm digital tape...it will show on TV or playback...but when I try to save to a video file the final recording pixilates in the middle of the video....will keep trying...one run on "motor"...the second on "bottle"....times and speed are displayed on the finish line.....

What kind of cable are you using to get it into the computer? I have found that using a FIREWIRE (IEEE 1394) cable is best for video. A USB cable will do what you are talking about (pixelating).

[RUBICON]

THANKS...The cam is my son-in-law's....I used a s-video and audio..I will have to ask if he has other cables...I know what you are saying...

[Chevy2ride]

I've driven from go-karts to econo dragsters and although my wife may say otherwise.............I'm not sure if my coconuts are big enough to take a ride on that rocket. :dizzy: It looks awesome and fast even standing still. I will definitly post a picture of that machine in my garage.:thumb: The creations I've seen so far is hard to keep up with. :hammer: So many ideas out there and it gets better all the time.:cheers: Why don't u email me with an address and I'll send u some choc covered macadamia nut candy from Hawaii. Even my wife enjoyed looking at the pic's. I would rather send u some beer but u know how women are............They think life is like a box of chocolates...........Aloha from Hawaii............

[elvergon]

Hey Rubicon, checking every DETAIL of your barstool I noticed you have the spindles the other way. I mean, what it is usually the braket is the one that has the axle of the front wheels and it attaches to what it is usually the king pin. I´ve seen at dragstrips that most drags use that configuration, however last time people just told me it was the same as standard spindles.

Is there any reason why you did it that way?

[c.schulz]

Rubicon, I'd like to ask where did you get the spoiler. Something you made or bought?
