turbo timer
I was looking on ebay at turbo timers and there were a few on there that looked like they were made of radio shack components, and only had 3 or 4 wires to hook up. Has anybody ever made one up? Maybe there is a diy that I havent seen. I'm sure Kwikkordead has probably done it.(he seems the type)

I don't know of anyone on any of the forums that built there own.
I don't have one I just watch until my egt's hit 300 and shut her down, it only takes a minute or two for this to occur. If you really want one check out some of the site sponsors. They seem to have pretty fair pricing.

This is what I use and it works great, plus its plug-n-play:

Or you can go with a crimestopper alarm

you do not need one... its a old OLD throw back thing when oils were not as tough as they are now. Shut it down when it gets to 350-400 and you will be fine. Almost 750,000 miles on PSD's and never a turbo failed from hot shut down.

I check my gauges but it seems like when I shut it down it is at 300-400. I suppose if I had be dragging it with EGTs at 1200 or so, I would let it cool down further but in this case, by the time I settle it down and park it it is already at that range.

Adding to what Joe said:
This is outdated thinking that goes back a long time ago for two reason.
First, oils were much more prone to "coking" back then than they are now. Upon hot shutdown, the oil would sit in the center cartridge of the turbo and cook, leaving a solid, ashy residue which was not good for the bearings.
Second, the bearings back then were made of babbit, a softer more malleable metal that was much more prone to distortion, especially with the ashy deposits from the coked oil circulating through the center section.
Enter the days of more refined oil ingredients, and better metal choices for sleeve bearings, and the need for cooldown is almost non existant.
I'll admit though, I do wait for mine to dip down to 300-350 upon shutoff, more out of habit than anything else from when I did not know this.
I would be most conscious of it after a long hard pull, when towing, etc.
Definitely wouldn't climb the hill to the rest area with foot to the floor, grossing 25K+, whip in at 800º, shut her down and run to the potty!

I must have a problem with my truck then.
Normally I slide in my drive broadside, go tokyo drift around my uncles house, blow liberal smoke on the neighbor's horses, slolum btwn my ATV trailer, outside water spicket, VW bug, and Taurus SHO, land in my parking spot, and jump out the window, slide across the hood Duke style and unlock my front door.
Wonder why mines always like 550-600
