NITROUS ?
I don't have a bottle warmer, so what's the quickest and safest way to warm up a Nitrous bottle to get tha pressure up a little w/o blowing up something?

A bottle heater is the safest. They are worth every penny IMHO. There are some warmers that you can store the bottles in that goes in the trailer. Problem is, they start getting cold as soon as they're installed on the bike.
My warmer is set up for internal and external power. In the pits, I plug it into a 12V marine battery and let the warmer run on it and keep the bottle temps up. I switch it over to the bikes system before I head to the staging lanes. I got mine from MPS.
Whatever you do, DON'T use a torch to bring up the temp. You're looking for things to go wrong using that to warm the bottle.

I use a torch. however, becareful not to burn your air or nitrous lines.

Is the pressure in the bottle a problem even when the air temp is average? or is this only a cool weather concern?

Brucer, Imma check with Scnitz or MPS about purchasing one. I cud use it now while temps are down.

Compton, Blk Ice and Dakota, I'm new to tha Nitrous end of things, so I'm not too keen on putting a torch to anything...lol! I wudn't even know which part of the bottle to put tha torch to or for how long. Imma stick with a warmer for now. Thanks guys!

Rook, yes it's all about the bottle pressure in the cooler climate months. In warmer weather it's not a concern but right now the pressure in a cold bottle may not be hige enough.

I try to focus on heating the liquid since thats the important part. I keep an eye on the gauge and heat the bottle to 950. I also always use a fresh bottle each pass.

Its always a issue. Warm months i keep the bottle cool with a wet rag and reheat if needed, cooler temps need to raise pressure. I mean you dont have to do any of it, but to keep things as controlled as possible i stick to the same psi all year, and tune the bike for a cetain psi.

Compton, do u ever have problems with your bottle leaking when it's full of Nitrous and the bottle's not being used. Do u ever notice it losing Nitous?

Never had that issue. Either your valve is bad or the oring on the threads where the valve screws into the bottle is bad. When its filled spray some soapy water around the valve it should bubble if its leaking.

In hotter weather, probably not. What you need to realize is, when the nitrous is flowing from the bottle, the bottle will get cold. This lowers the pressure. Not saying a bottle heater can keep up with the temperature change but it will kick in to help a little during the pass.

Bottle heater will do zero during a pass, and the electrical draw used isnt the best idea for drag racing.

I use the bikes power. The bottle heater system monitors pressure. Once the pressure drops to 925, the heater comes on. I did say it wouldn't be able to keep up but any heat applied during the run helps maintain pressure.

If you think so, that would have to be one serious heating element to be able to warm up and warm a bottle all within 5 seconds give or take a second when going down the track.

I don't understand why we don't see more systems like the Holtzman on bikes.
Bottle pressure does not matter. The nozzles themselves regulate the volume of nitrous. They spray a volume based on a bottle pressure of 300 psi. A full room temperature bottle is nearly 900 psi. Empty is 300 psi. At -30F a full bottle of nitrous is 300 psi. The nozzles spray consistent until the bottle is empty.
I have it on my snowmobile! 1000cc R1 bike variant. IT'S A 90HP SHOT!! Each nozzle sprays 15grams of nitrous per second. (1 grams of nitrous generally = 2-3hp)
Here are two videos showing it in action. The first video if you watch, you will see the two nozzles, they fog the box, and the blue lines feed fuel (tee'd from the main fuel line) to little brass sprayers pushed into the rubber velocity stacks.
http://www.youtube.com/watch?v=3KyQf6SpWt0&feature=g-upl&context=G1068cAUAAAAAAAbAA
The second video is a run gaining 20mph vs no nitrous, SHOWING the FROSTY bottle after the run!!! It was below 0F the night before and the bottle was left out in that.
http://www.youtube.com/watch?v=wEy0wBrYCX0&feature=g-upl&context=G1a3f4AUAAAAAAAVAA
I later had it on the dyno...on the motor 163hp SAE at the crank (PTO) and with nitrous it made 230hp at 9:1 A/F!!!! It probably would have made more, but I had an airbox lid that was made of breathable material.
NOW...I've had this for 5 years! Tons nitrous! But last year I changed the system. Now I run only ONE nozzle (45hp) and no extra fuel system, instead I add fuel with my PC3. About 45% is what I have in the cells on the PC3. -4deg timing too. Using a ZEX nitrous WOT switch.
I have the nitrous solenoid triggered off the PC hub for added safety, only allowing nitrous at above 8500 rpm and above 95% tps. Sled revs approx 11200-11500rpm on spray.
With all that said, in our bikes we face another problem. Our bikes might spray the nitrous through an RPM range, like from say 6000 and up at WOT. We could encounter knock without pulling some timing...but you'd have to ask those that use nos now!
Anyways....that's my two cents worth!! Thanks for listening!!

When I had nitrous on my Civic, I had a good setup. Bottle heater wired to an adjustable pressure switch. Had the electronic gauge inside. Set it to maintain 950 psi bottle pressure. Worked great. Should be able to make a similar setup on a bike.
