Does anyone run NOS Nitrous Oxide Injection on their ATV? I have heard about this and saw a kit for ATVs at www.magnumforce.com

I have heard that there is a guy running a megna supercharger on the DS650.

 

Damn, that would be cool. Just for the sake of strutting. :-)

There was a fully blown small block chev powered sand rail at Sand Lake a couple of weeks ago. Totally sweet machine. Had the B&M twin side draft carb supercahrger. It was a long chassis, four seater with about 18" of suspension. Totally trick.

I could imagine the fun of idling through the parking lot with that supercharger sound! Let alone the speed out on the flats!

What drives that megna supercharge on the DS? I can see a supercharger fairly easily and I have seen superchargers on Harleys, but I never really investigated what motivated the supercharger in the first place. Do they modify the head to run it off of the cam drive train?

Keep us informed on your quest for speed! :-)

I don't know much about his setup, something about running off of stator, but he posted some info at http://www.ehlertpowersports.com/for...d_ID=617&mc=59

Also some info on NOS at: www.highpower.freeserve.co.uk/technical.htm
www.highpower.freeserve.co.uk/faq.htm

 

i run it off the stater 3 rib belt. cut intake tube down weld 3/16 plate to intake. 3/16 plate on carb side. weld tube from intake on carb side. moves carb back 21/8". idler off old honda from junk yard. 40 hr. fab time. too much time at machine shop.

 

Alba action has an ad out in the new dirtwheels with a lot of parts for the ds including a supercharger kit that will soon be available.

 

I just sent Alba an e-mail asking about the supercharger kit. It looks like they also sell those NOS kits for ATVs.

 

One more question...

Any thoughts on wether NOS is best when used with 110+ or Methanol?

I have a 39PWK CT alky carb, but am undecided as to install it or look more into a NOS set up/

 

my main problem is detonation over 8 psi. boost with vp red. im going to try a msd magnet pick up with boost retard. this will get rid of the ds ignition. then i could set and control my timing. the alba kit will be around $2000.00 with eaton blower. i tryed nos you have to put a fuel block before the pet **** to run a fuel pump. nozzle in manifold boot with 2.5 lbs. bottle 25hp jets. you only get 18 seconds.

 

Speaking from muscle car experience... it's not mandatory you run higher octane while using nitrous oxide.

Gasoline octane should be chosen appropriately for each engine based on it's modification. If the engine is stock, there is NO need to run higher octane, you WON'T see a HP difference. Your just wasting your money.

A good scale could be...

10:1 compression ratio can use 92 octane easily.
11:1 should use 94-98
12:1 96-100
12:1+ 100+

Keep in mind, the type of plugs you use, jetting and especially timing effect an engine using high octane fuel.

Basically when adding NO2 to an engine you want to ENSURE you get plenty of fuel to the motor (for this reason most kits include an electric fuel pump) because if you spray a load of NO2 in the engine and it can't pump gas fast enough in there to burn, your gonna lean out big time! and KABOOM!

Basically you're burning pure oxygen when using NO2, it's bonded with nitrogen to stablize it, because if you were to burn just pure oxygen, you'd melt the heads. It also cools the combustion chamber considerably (due to the transition from liquid to gas from the bottle) That's why the bottle gets cold as hell after spraying it for a while (like old freon cans for AC).

Well, that's today's lesson in Nitrous!
