I am a newbie to nitrous as well. I got a lot of good info from the people on the site here.
I just installed a boondocker kit on my 08 MTX and it went really well. The most I can say is that it was easy to understand and follow install directions. Also on the tuning end the guys at Boondocker were very helpful and patient with my questions. I got the synergy kit with tuning box and the regulator. I am going to add a Exhaust Gas temp gauge soon for tighter monitoring. It was fun to install and on the test runs and early tuning, I can tell this is GONNA BE FUN!!! Already took my nytro to the stock apex level...But the APE is gonna get BOOSTED this summer!!!!!

i would go for it. as long you have set up right you will have no problems. I run a nos wet system. and it hits hard. the only bad thing is it just seems like the bottle is gone as soon as you hit it but it is worth it. when I get chance I'll post my install picks. good luck

ok now how much setup or tuning are we talking about and what are we tuning in all the tuning in is within the kit itself right im not gnna have to play with electricals or any of the settings on my sled itself or is that where the reclutching stuff comes in.. cuz im afraid im going to mess sumthin up or blow my motor and wouldnt even know where to start for the "tuning in"
-Thanks
-Thanks

Depending on the kit, you may not have any tuning to do. Maybe some fine tuning but if you buy a kit that is built for your sled, you won't have any "tuning" to do. If you only run a 30HP shot, you probably won't have to do any clutching. You'll just have to try it and see if you hit the rev limiter. If you do, you'll need to add some clutch tip weight. I doubt you'll have a problem with 30 hp though.

What I meant for tunig is just like Stoutner said; you wont have to do anything with the rest of your sled unless you go for monstrous gains 80-100HP. It is all about tuning the control box or actually fine tuning the settings that are alreaddy pretty right on for your sled out of the box. What takes a little time is getting that perfect air/fuel mixture to produce optimum HP from your set up. If you err slightly to the rich side you are more than likely not going to damage your engine. So far, outof the box on some 2-3 second button pushes I was noticing 200-300 RPM increase and it helped me push past the high mark level in same snow conditions of when I was not hitting the boost. It all seems like greek for now, but you'll love it and its fun to learn, install and RIDE! Lots of support from here too!!!

Using a NX based kit the air fuel is controlled with jets and there is a chart showing what jets to use for what HP, ZERO tuning for air fuel. Still have to clutch it though.

Kinger, I doubt he'll have to do any clutching for a 30HP shot. I was able to run my Apex with stock clutching and a 30 shot no problem. I didin't start hitting rev limiter until I went 50 shot and higher.

Hey Stoutner, can you elaborate on rev limiter a bit for me please. I know that with the direction I am going to be going with my Apex and Nytro, I will soon have to start tweaking other parts of sled-i.e. Clutching...Maybe redirect me to another part of the site that has this info. Thanks!
also, what is this TORS thing?

TORS is the Throttle Over-Ride System

True you cant even run a 30hp shot on the NX kit, lowest is 40hp and requires clutching because its "wheel hp" not crank hp so its more like a 55 shot on a holtzman or Boondockers kit.
Race blue check into a shockwave helix, I'm going to give one a try I LOVE nitrous but the riding 600 miles underclutched and overgeared for 30 seconds of 140+MPH leads me to want some way to get some power back once the nitrous runs out. Its also a easy way to keep yourself off the rev limiter

I'm still on stock clutching with a 50 shot. altough i have been riding on hard pack snow condtions. and kinda hook up. But let me tell ya it was way to much FUN smoking my buddys f7 sno pro. He has a head, y pipe, pipe, clutch work, picks, boon docker cotrol box, plus a few things I don't Know about. he dosen't like me any more. lol

Tors is just a safety feature in case your throttle sticks. If it is working, don't worry about it. It has nothing to do with performance or nitrous. It is a little microswitch that is built into your throttle assy on your handlebar.
Apex's have a rev limiter built in to the electronics so the sled will not rev over 11,200 RPM. I don't know what the limiter is set at on a Nytro. On the Apex, you will probably rev around 10,700 rpm when not using nitrous. When you add that extra 30 hp you will probably be revving around 11,000 or so. Of course RPM's depend upon conditions. Heavy snow it will be less. Glare ice will be more. On an Apex, you can just about get away with 50 HP extra and you will be revving right around 11,200 under hadr acceleration. Maybe you'll even hit the limiter once in a great while...especially if you start spinning due to icy conditions.
That's why I say you can get away with a 30 hp shot without any mods.
Kinger, I think he is talking about adding 30HP to his motor...not his track. You can go as big as you can afford. My problem with a larger shot for trail riding is you run out way too fast as you already know. Also, if you go larger than a 40 or 50 shot, you will have to do clutching and I honestly don't think a clutched 50 shot is any faster than a non-clutched 35 or 40 shot. Adding that extra clutch weight definately hurts your "off nitrous" performance...albiet not that much.
