Yea jgdakotanc you can get the stuff at radio shack. Get a 1/2 watt 10K ohm resistor and wire it to the IAT connector. That will tell the PCM that it is approx 80 degrees outside. If it were me I would buy a 50k ohm pot, a 15K resistor, a DPDT switch, and a small project box and build the IAT adjuster. Then you can adjust the temp to be whatever you want
All of that stuff will cost you about $10 and you will have a better product than the Ebay ripoff. That guy is making a killing.

I'm not totally convinced that a FIXED temp should be given to the PCM.
I modified mine, but I installed an inline resistor that show the PCM a cooler temp than it actually is, while still maintaining changes as I drive thru diff temps and climates. I live in Phoenix, Az and drive up into the mountains where it is 20 degrees cooler in the summer and temps get down to the teens in the winter. I'd really rather not show my PCM it is 80 degrees all the time LOL!

Hey Buck, you sound like you might know a little bit about this stuff. If you think that it's a good idea, and it's not something that's gonna f my truck up, will you give me a few more details on building that kit. Would YOU put something from radio shack under your hood? I'm all for the $10 project, and I like learning to mess with stuff that I don't know about yet, but I don't want to get in over my head. If you don't mind, help me out just a little, either on here, or you could e-mail me some more info gates@olivianc.net
Thanks

Yes I recommend building and using this adjuster...Radio shack will be fine for the parts
Well here is what I did... I went to radio shack and got these parts
271-1321 1K-Ohm resistors $.99
274-407 1-1/4 Hexagonal control knobs $1.79
270-1801 Project enclosure $2.29
271-1716 50K Ohm Linear Taper Pot $2.79
275-691 DPDT heavy duyt rocker switch $3.49
I already had wire on hand so I didnt need any but if you have to buy some, get 22 guage wire in 4 different colors.
Here is the link for the schematic and some other diagrams
http://home.earthlink.net/~rpkast/IAT%20Adjuster/
If you need any help email me and I will help you out. You need a soldering iron(not gun) and some good 60/40 rosin core solder. Once you get it made you can use a DVOM to set the adjuster. Larry of J&J Auto made a great post with the resistances and temps they equal. If you cant find it email me and I will dig it up for you. My email is Bjmlittle00@aol.com

IAT temp chart
Resistor = IAT Temp
3.9K = 118F
4.7 = 109F
7K = 89F
11K = 73F
15K = 60F
You can figure out what's in between each range by using some common sense.
I still am not convinced in using fixed resistors when the outside temp varies from morning to night, etc.
You would be better off inserting more resistance inline with the IAT still hooked up and functioning, that way it still adjusts for changes in ambient temp while still showing the PCM a colder temp reading than it actually is.
And, if everything is still stock on your engine as far as induction goes (Cold Air Intake, S/C, Turbo), why do this mod?

Hello all,
I guess you may not have been around in 2001, on this forum, when this 'blower' was discussed.
Bernd, who used to be the forum 'guru', said he hooked two of them inline, dynoed it, and saw very small gains. He said two together made about 1 psi. Feel free to correct me if my memory has had a bit too much homebrew beer.
Someone even posted a pic of a leading manufacturer's leaf blower, with the long tube and all, powered by a 110 volt cord. We joked about runing the quarter with a 1/4 mile extension cord, then you'd loose the boost when it unplugged itself.

Now that would be some funny a$$ sh*t!
I'd go to the track to see that run!
I'd bet it may give some low RPM boost on a econo box Ricer.
Now, if you could take a impeller type leaf blower and run that sucker 36000 RPMS off of the engine crank you'd see something LOL! Just hope that plastic impeller doesn't blow down your wide open intake with the engine doing 5500 RPMS!!!

im surprised no one said it but you could just by a power converter that runs from 12volts dc and will make it in to 120volt ac find u a extions cord to run your leaf blower and viola!!! All that from your ciggatte lighter

If you converted the horsepower demand to turn any impeller with required force to deliver noticable boost, it would never run off of a cigerette lighter style inverter, yet alone almost any descent/affordable inverter.
It would take a few thousand watts to create any usable boost I am sure.
I bet the common leaf blower would fail to start on a 400 watt inverter. Brush style motors demand very high power to start.
The leaf blower was still funny as hell and WAY more practical than any inline propeller purchased on eBay HA HA HA!!!!

Sorry nakonap I couldn't help myself by getting technical with "if this would work" mumbo jumbo...
But like I also said, the idea was funny as HELL!
I sure as hell laughed my ass off over it.
I'd sooner beleive a leaf blower gave usable boost over that joke on eBay!
Going back to the original subject... err... has anyone here ever tried to make a real home made supercharger? I've heard some people swear it has been done. Buiding something yourself that gave that kind of power would be so awesome. If I could fabricate with any luck of tight tolerances I'd take apart this old turbo I've got and drive the impeller only section with a serpentine pulley. If I only was rich enough to have a machine shop of my very own...sigh :-p

120,000 RPM,s damn that's alot. You would need one hell of a small pulley or one BIG crank pulley to get that. Is that what a Turbo spools to? I'm sure the altenator spins about 36k to 48k range. I was thinking around that.
If I ever did such a task, I'd probably leave max boost about 7 psi to ensure reliability from my daily driver that I depend on to get my family and Quads around without blowing up 200 miles away!
However, I've also got a Cirrus my woman drives. It's a small V6 with about 75K miles on it. I'd sooner mess with that because she only drives it to work, we don't take that out of town.
I do plan on getting a S/C for my new Dak eventually. I'll probably buy a bare bones unit from Vortec or something. I could build all the mounts at home. The complete system seems to run close to $5k while a system for a Mustang or a bare system cost under $2k. I'd have to figure out the fuel management on my own in that case.
