Nitrous

[sweav]

Hey evryone, just starting on my bsr. Finished my sons go kart at the start of summer and have been wanting to build one ever since then. I have drawn up my own plams (no offense to Mikes, it looks great) and this site has helped out ALOT. Does anyone know where the best place to get rims and what size, I have 4.5/10/5 and 7.1/11/5 slicks. Also, I am getting a 6 1/2 horse, has anyone ever put nitrous on one and if so where can I get the kits. Thanks for any help.

heres some information on nitro http://barflyracers.com/showthread.php?t=174&highlight=nitrous
go to www.gokartracing.com for rims. hope this helps.

Thanks sniffles, that helped out a bunch. I found a kit from holly. Little on the high side but it points me in the right direction

Hello, Try searching in ebay for nitrous system sneaky pete! I saw one the other day for around 200.00 complete New! Try also for tires there to. I just bought a case of 12 Firestone 8.00x 11.5x6 for 175.99 plus 23.87 shipping. Plus I also bought A lot of the parts for my dual wheel bsr through ebay! :wave:

hey moto, found a dry system pretty cheap. Since you've messed around with the nitrous, do you know where to get a small pump, solenoid and fittings to make it a wet system?

My first advice is for you to at least research Nitrous systems to understand the fundamentals...I am far from an expert...but I have a system on a 90cc engine that actually works well...The first thing is to understand the difference between wet and dry systems. Dry means no fuel ( gasoline ) is being sprayed with the nitrous. These work on lower HP systems that have fuel injection ( the nitrous is sprayed i think ahead of the MAF sensor ) that way the fuel management computer compensates with more fuel. The other way is by increasing jet sizes in the MAIN circuit of a carb....A wet system combines fuel and nitrous...via spraybars, nozzles, or foggers...the fogger disperses the mix into the intake and the most important factor is that it prevents a over lean condition...LEAN will explode the motor....Remember that you are adding a powerful oxydizer and need fuel to burn with it...This is where the jet sizing comes in...and you will need to enable the system only at full throttle...if you close the throttle with the system enabled....cough...cough......bang......You will need a pump, switch, battery, fuel solenoid, hoses, and fogger in addition to what is in a dry system...the pump can be anything from a generic aftermarket VW electric pump to a motorcycle pump ( like mine )...mine has a small gage that reads 5psi of fuel to the solenoid....fittings and hose are regular e-bay items..as are solenoids and bottles....beware that a lot of small bottles on e-bay have bad valves that cost as much as the bottle to replace.....the size of hose fittings is -4AN on everything upstream of the fogger and it is -3AN ....good luck

Hey sweav
I see that you are from Tulsa. I live in Claremore. It is great that someone from around here is into BSR's . I have seen a few around but most around here haven't ever seen one. Drop me a e mail . war-paint@cox.net

Oh hey! How did you find this site?

[sweav]

Thanks Rubicon, have been doing alot of reading on the nitrous. I just want to put it on just to have it there. It's a play toy, why not. I think I've found somethings for the fuel side, one question on the fuel pump. Do you have to run a regulator or is it built into the pump, and do you have it set up that when you turn the system on the pump kicks on or when the system is triggered? Don't know why but I'm just determined to put nitrous on it! Probably scare the hell out of myself and never use it again.

hey sweav what engine are you going to put nitrous on? just curious

[sweav]

Electric start 6.5 or 9 horse honda ohv. Haven't figured out wich one yet. I have rough drawling of the frame and got the barstool today. I think the 9 is going to be a bit much plus I don't think I can get 9 horse under the stool without alot hassle to make it fit.

personal thanks....i an seeing some interest in nitrous....i see little inquiries to me for advice.....I am absolutely not an expert...but....if you filter out all the "SMACK"...how many can show pics and discuss a REAL system that "WORKS"...thanks again

[RUBICON]

Great questions....I may can answer....I think most pumps....car...cycle...all that are for carb systems put out around 5 psi...more or less....in a pureist world like drag cars the overall fuel and nitrous delivery is affected by the fuel and nitrous pressures....but for what we do...get real....i do have a small pressure gage ( autozone ) ( 1' in dia ) and it reads 5psi....as to the operation...I have an "ARM" switch that puts power to the fuel pump and to the activate switch in the throttle assembly ( just like a drag car).....when I want to use it I open the bottle valve.....I "ARM" the system...I also have a button that parallels the throttle switch...I press it for an instant...it "SPANKS" the motor ( makes it surge like it was slammed in the ass!...cool stuff )....I hold the brake....bring the motor up on the clutch stall.....release the brake as I hit 90% throttle ( if I hit 100% the nos kicks too soon and bogs the motor )...when teh motor starts to breath ( 50%rpm ) I hit full throttle and the nos is enabled.....all I do is hang on and hit the pedal shifter...10' of air in 2nd....8' or so in 3rd..and a couple @ 4th....and I weigh 285......NOS is real and alive for me....til the engine pukes!

Hi There: I just read the information on the sneaky Pet system it comes with everything you need the way it was described to me. It has an arming switch,silinoid, plastic hose to go into the air filter and a battery pac that consists of two 9 volt battery's to make it work! I guess I might be missing the point here. (NOS) kit looks pretty complete to me, you just put in the right jet, they supply a few and wire the thing up and have the bottle filled and hang-on. I would like to know on a small 6.0 engine what jet would work to keep it from blowing up the motor. It sounds to me like it is a very possible to install one of these things on a stool.Garman351

JUST A QUICK NOTE THAT MAY HELP YOU OUT?
IF AND WHEN YOU INSTALL THE NO2 SYSTEM, CONSIDER A PURGE LINE, THAT WAY YOU WONT POUR A BUNCH OF FUEL INTO YOUR MOTOR. BUT MOST IMPORTANT !!!:blob_red: , AFTER YOU INSTALL AND JUST PRIOR TO YOU "PUSHING THE BUTTON" DISCONECT THE FUEL LINE AND PUT THE END IN A COFFEE CAN, THEN PUSH THE BUTTON, IF YOU DON'T GET FUEL RIGHT AWAY, YOU MIGHT NOT GET FUEL RIGHT AWAY WHEN THE N02 IS TURNED ON. OF COURSE YOU WILL DO THIS WITH NOS VALVE CLOSED ON THE TANK. THEN WHEN YOU DO GET READY TO DO A "TEST" RUN 100% YOU MIGHT NOT HAVE TO LOOK AT RODS, BEARINGS, PISTONS ECT...
JUST MY 2.5 CENTS WORTH WHEN IT COMES TO NOS.
