Youll need a NOS bottle warmer for the propane tank with 85* thermostat. I was wondering if a Co2 bottle would work? They make anywhere from 2.5 oz to 2.5 lb bottles.. seems like they should work, as long as they could be filled with a bigger tank.

What bottle warmer to use for propane tank? Do you need one if you run the bottle upside down which is better up or down?
What solenoid do I use for the propane, will any fuel solenoid work?

The pressure will not vary depending on whether you run the tank upside down or not. As stated above, the noid needs to be able to handle your working pressure.
Also, regular propane tanks are designed to be upright. The OPD valve has a float stopper in there to keep from over filling the tanks. If you flip the tank upside down, this float is going to shut off fuel flow. So you'll need to take your tank apart and modify it so this doesnt happen.

I was always with the understanding with the bottle right side up you had to have more pressure in it because it was in gas form. thats why i ran mine upside down, so i could keep it at around 60 psi instead of 100+ ?

For the heck of it i thought i would post my dyno sheet from when i was doing the two stage (dry kit, and wet propane kit) nitrous kit.
The motor is all stock internals execpt the tr224 cam. It still has stock heads. At the time the bolt ons consisted of LS6 intake, and mac mid-lenght headers, and lid + K&N. No underdrive pulley or other.
anyway here is the dyno sheet

as far as sizes go. I had a 100 dry and a 150 wet
the plan was to get a 2-stage window swith but then i just decided to go turbo

You always used the heater to get your desired pressure. The only thing you were changing was the volume of fuel you were feeding. With propane, every 1part liquid=270parts vapor. Liquid form is the way to go if you can get it to work consistently. The cooling properties coupled with its octane makes it pretty advantagous. Its too bad nobody has taken the time to market a useable conversion kit for nitrous.
okay i see what you are saying now. I was meaning you don't need as much pressure if the bottle is upside down to get the right mix. I understand it doesn't change the pressure either way. my bad

Some questions.
1. Do you still have to retard timing using nitrous/propane?
2. Will you gain more power using nitrous/propane vs nitrous/ gas using same nitrous jet?
3. Can propane be used by it as dry kit, if so do you have to add more fuel?

yes and no, it will allow more timing safely because of the higher octane. However, all parameters still need to be assesed before adding a gob of timing.
2. Will you gain more power using nitrous/propane vs nitrous/ gas using same nitrous jet?
No not really, with all parameters equal. Like above because of the safety factor of the octane, you can run bigger hit and more timing safer, so it's all in your final tune.
3. Can propane be used by it as dry kit, if so do you have to add more fuel?
You use the propane as the additional fuel, so no additional gas is needed. Unless you want to add propane as a kicker to an allready set-up system that may be running lean (3-way system).

I haven't really seen this touched on much yet.
NHRA rules wise, I am guessing they would have a real problem with propane, no?
My local tracks are pretty lax on the rules so I do not see it being a problem here, but I was wondering about going somewhere else. Like to an event where they stick tighter to the rules and check everything.

Would methanol/alcohol be cheaper and easier, yet yield the same results as propane? I do know that methanol has a better cooling effect than propane and you can add denatured alky to richen some windshield washer fluid, which is 10% methanol from what I understand.
