Is this possible? Has anyone done it? I'm trying to figure out how to run a small shot of NO2 in the safest way possible untuned due to the year of my truck. I have seen death shadows single port wet setup but not sure if it is safe to run without a standalone. Any input would be appreciated. Thanks

just tap a wet shot into the intake piping

As far as I know, there has not been anyone that has run a direct port setup on a 1GR.
I think if you are going to run it with a supercharger, you might have a better result running it through the blower to cool it off. The old style 3 lobe rotors are not very efficient and make a lot of heat when the boost level goes up. Running the nitrous through it pulls a lot of that heat out.

Interesting...what about just running a water/meth injection system instead then? Cheaper and/or easier?

Eaton has discontinued production of the 3 lobe rotors I have been told.
A few years back they came out with their 4 lobe rotor called the Twin Vorticity (TVS). It is a much better design.
Here is the problem. The older 3 lobe nose dives in efficiency as the boost pressure goes up. The pressure in the manifold exceeds the pressure between the rotors so it backs up and makes another pass through the rotors and the heating of the air really goes through the roof. Hot air does not make power.
The best positive displacement type is the Lyshlom type. This uses a male and female rotor with a lot of twist to it. This is the type that Whipple makes and is sometimes called a twin screw. The advantage here is the air is compressed between the rotors and decompresses into the manifold so the pressure between the rotors is normally higher than in the manifold so there is no back flow problem.
The disadvantage to this type is that it is much more expensive to make. Have two different rotors and a gear drive that turns each at a different rotational speed. At very low boost they are a tad less efficient that the Eaton 3 lobe, but as the boost goes up they really shine.
Eaton's 4 lobe has the advantage that both rotors are identical so they are cheaper to make. Has a higher twist rate than the older 3 lobe so the back flow problem is greatly reduced. Still does not equal the twin screw, but gets much closer. The TRD Supercharger for the Tundra uses the 4 lobe version, Corvette and many other new OEMs are using the 4 lobe. Oddly the HellCat is using the Lyshlom made by IHI in Japan. Likely some left over Mercedes AMG influence.

good post gadget
I've ran meth in other turbo cars and i don't see you making much hp using it in this application. running a e85 tune would be better then a meth kit

That might help, but if the core in the unit is to small, it still won't make much of a difference. It is still better if possible to start off cooler.
Anyone local to URD wants to try that I have all the instrumentation needed to test that out.

Gadget I just moved about 30 minutes north of you and was wondering what this would take to test

If you mean the water pump for the Trd s/c whitebeauty installed a better pump. I have it in my truck and I added mo cool to both my rads. Plus a e-fan on the rad and to be honest I don't think it does to much. I believe the only way to make power out of these s/c is nitrous and if you don't want go that route then go with URD Rotex s/c kits.
You know Gadget, if you collect all of your posts of this nature, and put them in a book about engines and boost, that would make one hell of a book. So informative and rich in information.
Nitrous through the blower is the way to go. Just make sure the bottom end can handle it... Guess how I know. But a "50 shot" picked up almost 100ft.lbs on the dyno. Now if there was a less "rinky-dink" way to tune my 2009 I would have continued seeing where the combination could have taken me after I rebuilt the engine with forged rods/pistons/studs/etc

A wet shot of Nitrous through the blower on a small shot for sure; it would take a lot of effort and money to do direct port for such a small amount of spray.
A well tuned single point wet setup is typically good for up to about 150 shot before you need to worry about pooling & distribution depending on the intake manifold design (obviously dont run this amount of spray through the 1GR if u want it to last).
You need to be absolutely sure your AFR is kept on par and that knock is kept at bay given the amount of power that you will make. You are pushing the limits of the 1GR with boost and spray so there is very little room for big mistakes (some cant even get just boost right).
**You should spray higher in the RPM range, stay away from low RPM peak torque area.**
If you don't know what you are doing or don't know someone that truly does id leave it be.
There are plenty of claimed engines on this site from boost alone.
