Excellent Buckeye320, it seems you have your head screwed on straight

and there is nothing wrong with wanting to learn all about these amazing little machines. The engine I was working with last weekend (Jet Central 60 Super Bee) at full throttle runs at 181,000 rpm.
On the subject of fire extinguishers actually the AMA rules require the ABC CO-2 type but also a water base type must be on site, sometimes the club provides the water base but when we donated one to the club it quickly disappeared. The four jet guys at our club now each carries his own water base also. Those are mine in the picture and I make sure I always take this one also when none of the others are going to be there.
Dry chemical types should also not be used since this can damage your turbine. Co-2's will not harm the engines.
Here is a direct link to the Actual AMA turbine safety rules:

Now if you are an AMA member you can access in the members only section of the AMA website a full listing of every single Turbine Waiver holder in the US. I think its something around two thousand folks and connecting with any of them on a local basis is an excellent first step in enjoying your engine.
Also another and popular way to do this is to visit any of the Jet Rallys that are all over the country now. I highly recommend networking in this way since this also opens up the possibility of obtain not only help but a source of all sorts of used equipment that may be difficult otherwise.
Curious if you obtained your engine used and how many hours?
Also since this is the airplane beginners forum its probably best for future turbine questions to go here: You will get lots of good answers there>
