NOS Sneaky Pete System

[Trucker200X]

I have that NOS Sneaky Pete System which I bought from my buddy who used it on his Boat but it didn't show much improvement so he sold it to me and I never put it on anything. The Sneaky Pete System isn't much, its a 16oz bottle and adds about 2-3 MPH gains and 3-4 Tenths off your 1/4 mile time in a car. I have been thinking about going ahead and making my 83' 200X a "Test Bike" and seeing how the motor would react to Nitrous and what modifactions might need to be done, I will also find the pro's and the con's of having Nitrous...I was just curious if anyone else has done this and how did it work out?...

[NOS_350X]

you definently need Heavy duty cam, valve springs, and valves. And to get the best results get a high compression piston.

[mudduck14843]

stainless steel valves, heavy duty valve springs,high compression piston,hp cam... basically set it up to run alky and you shouldn't have too much trouble.oh and definatelly a hp clutch kit

[BigRedRunner]

Might want to retard your timing a bit. At least thats the way it is on cars.

[Trucker200X]

I think I am probaly going to give it a try...Just to see what happens...If I blow the Motor...Then I will know I need to do some work to it...lol... I will keep ya guys updated...I think it will be a fun experiment...

[J.D.]

Actually I've heard the best way to do nitrous is leave the engine pretty much stock as far as compression. And it makes sense because you put high compression, and THEN nitrous, talk about stress. Beef up the valve train like lifters and such, but leave the compression stock.

[Trucker200X]

Well, I think I am going to just leave everything stock and see what it does. I am going to mount the spray jet in the rubber intake but right before the carb. I will mount the bottle on the left hand side of the bike on the frame rail, the solenoid will be mounted on the frame rail buy the brake resivor...I am going to put a micro switch on it some how so has soon as I hit the throttle its spraying...I also got the purge solenoid which I may mount up...have it purge right behind the seat...

[JMiller]

Let us know what happens :?: :?:

[HemiChallenger71]

The lower compression is a good idea, be sure to get a forged piston, if you want to use a lot of nitrous, be sure to beff up your rod as well, I've herd of 300EX rods working really well in 200x's. Retarding timing would be extremly beneficial, but I'm willing to bet our small machines don't have all that much timing in them anyway. Use a colder heat range plug, use two ranges lower if you are using a lot of nitrous. A mostly stock engine setup is probably your best bet. Using heavier cam and springs can help i guess, it depends on the cam really, nitrous works in mysterious ways. How much is a lot and a little nitrous for a bike that size is questionable as well. If you use like a 10hp shot or more I'd say you should probably use race gas when you plan on hitting the bottle. An extra 10hp is a lot for a 200x or any three wheeler really. I dont think it's a good idea, but suit yourself, those are a few things you should worry about when hitting the bottle.

Also only hit the nitrous on WOT. Also remember you only have fuel from gravity, no fuel pump, so don't go to crazy.

[Trucker200X]

I will...I think if I do a small enough spray it should hold, yet give it the "boost" I would beable to feel...Should have it done in a couple days...

[dogger]

hey hemi made some good point's also don't for get you'll need to add more fuel or you can have a problem.

[Trucker200X]

Well for fuel I am going to use 101 octane, Its on pump at a local gas station and is fairly cheap at $3.00 a gallon.
I am going to start small and work my way up.
First time I use it I will have the smallest shot..around 5hp..I will have it on the micro switch setup so has soon as I hit the throttle it will activate and spray.
If all goes well I will step it up a notch...and just keep tweaking and stepping it up untill it either 1. Blows, or 2. I see a weaking in the power.
Also remeber the Jet will be loacated in the air tube so it will not be getting most full effect as if it was on a car and located under the carb on a plate.
I will be sure to take plenty of pictures and keep you guys updated.

[mudduck14843]

my step father had a nos setup on a old chevelle and one fall day the dam car wouldn't start so i hit the button then the ignition....OOPS!!!!
parts went THROUGH the fn hood NO JOKE it blew the intake right off the block...I knew then why he always told me NEVER to shoot it below 6000 RPM!
this was a setup from about 15 yrs ago i would imagine they have come along way since then but just be carefull!!!

thats the way the Boondocker nitro kit is mounted.

[Trucker200X]

BoonDocker? What is that? Can you get pictures? May help me alittle...Actually any pics of quads or trikes with NOS will...

[350XXX]

i have some info on it in a Dirtwheels mag. i'll post it in the morning.

[Crash104936221]

i would adjust the micro switch to give it nitro ONLY at 7/8 to WOT

becuse at 1000rpm 5hp is 26.26 extra foot pounds that the engines not designed to handle
and its 52.52Ft/lb @500rpm(5hp shot)

thats a .2lb/min shot your using eh?

my guess is that if flow is started when the engine hits 4500rpm that a 20hp shot should work but i would imagine that the life span of the engine will be ALOT shorter

20hp being .8lb/min if my memory serves me

[NOS_350X]

thats the way the Boondocker nitro kit is mounted.

I was going to say that. Boondocker claims that its a much safer way to run it rather than puting it between the carb and intake. It makes sence. And the kit they sell is only $400

[Trucker200X]

Very interesting Crash, I may consider doing it that way. I am going to "Try" and do it right the first time...Maybe save myself from buying a new motor...

[Crash104936221]

how are the guys runing nitrous on there raptors and such getting the extra fuel the engine needs into it?

i think the Canondale 440 EFI engines would be a great one to inject due to the existing fuel system and the ability to adapt it to inject more fuel when you hit the switch

hmm 350X with a modified canondale 440 W/Nitrous :shock: :twisted: :twisted:

just looing at Holley's site (NOS Nitrous Oxide Systems) and seen this page for motorcycles http://www.holley.com/HiOctn/TechServ/TechInfo/NOSTech8.html

and some other stuff in the web site

will post more as i find/ think of it

*edit*
just had a look at the sneaky pete and its a fair bit difernt then the pic above lol

a good read on that site seems to know his stuff

[tri-freak]

set your carb richer. cuz all nitrous does is let you burn more fuel. make sure your not burning too much extra fuel, or your engine will bog out. trust me, my dads boss has a '68 chevelle dragster that runs 11.5 seconds consistently on just gas. we have a NOS cheater kit plugged into the nice demon carb, and it just bogs like a mofo when we hit the nitrous. too much fuel going into it too fast. so over the winter, we're gonna set it up too boost the spark when we hit the nitrous. otherwise, she just bogs out. and also jet a little richer, so the idle is quite low and stalls easy when cold. this will help get more fuel into her when you hit the nitrous. i hope this helps and good luck! make sure u wear a damn good helmet when you try this too! peace out, tony

thak yo 452x, i hadn't got the chance to post that yet.

[Trucker200X]

Thanks guys for the picture and links. I think this will help me out alot in the Riggin' process. I will keep you all updated and take plenty of pictures...Thanks again all!

[bigred110]

Make sure you get a bigger jet before you does this. NOS takes gas away, so you need extra gas for the engine to burn. Retarding your timing is a good idea.
Make sure you pick up some new spark plugs to, so you can do plug checks after each blast.
If you can put the nozzled past the carb. Thats how most systems are setup.
I had NOS on my elco and boy that was fun :twisted: :twisted:

[bigred110]

And also get the highest grade of gas you can get to.

[Trucker200X]

I am going to run the Nitrous jet before the carb, If my stock motor takes it well I may move it to after the carb. I will run probaly just 101 octane and maybe a octane booster. Im trying to figure out a way of setting up MSD or a similar type of ignition box on the Trike. I don't really know how it could be done...but anything is possible. I have been thinking of making a swing arm for my Trike...Would it be TOO trashy if I made it out of like a 1 1/2" or 2" tubing..Also cutting off some pieces of the stock one and rigging them onto the new one? I would do I good job on it but I just don't know if it would be too trashy...I got everything necessary...Lathe/Mill, Welder, Torch, Drill Press, And every thing else I would need...What do you guys think?

[Pete]

you need to run it between the carb and the engine. Running it before the carb can cause a nitrous blowback when the slide closes. Thats not good.

You generally want to leave your compression and timing stock when first using nitrous...as you get a bigger and bigger shot you actually want less timing and less compression.

If you're really going to do this on a 200x, I'd give it a SMALL SMALL shot...like maybe 5hp tops. You will have to jet the carb rich since the sneeky pete uses no external fuel enrichment to compensate for the nitrous.

[CartmanKXT250]

Yeah and when your not using the bottle it will be rich as hell and not fun to ride..but when your on the nitrous it will be running properly.....I'd say screw the sneaky Pete setup and buy a regular wet system with a fuel jet and a fuel pump

[trikerider2oo7]

get a video of it. i wanna watch it throw you off.

[Trucker200X]

TrikeRider2007, It's funny...Most morons...Like yourself watch "Fast and the Furious" and think you hit this magical button and BAM!...You do this sick as wheelie for 5 minutes and go from 0 to 150 in 3 seconds...Sorry bro...Don't work like that...Yes you get a nice hard launch...No my set up won't be insane enough to throw me off...If anything it will shoot my rod through the side of the motor...

[Dan Tenn]

"If anything it will shoot my rod through the side of the motor..."


Thats what I want to see video of. :-D

[200Xtreme]

Trucker200X hit it dead on!! (about the morons who watch fast and furious, and believe that trailprotrailprotrailprotrailprotrailpro )

[short4stuff]

trucker did you do it?? Or are you still going to ?? Update this!

[Trucker200X]

Well no, I ended up selling the kit and bought a 4 wheeler...But now I just recently tore the 200x apart and I am going to restore it and I am getting some idea's in my head for restoring this trike to a...well I don't know yet...something fun, fast, and PRETTY!...I will get pictures of the rebuild and the possible motor I am going to put in it...

[LaDano]

The biggest mistake is running lean. When nitrous goes lean things tend to go boom, not good while sitting on it. Make sure you run some way of extra fuel at wot.
