Why Meth?
It chemically cools the intake air and supplies a denser charge? Is it only a safety measure against detonation or will it help provide safety and area under the curve(more power though out? Newb to FI

It depends on how you tune it. If you optimize your tune on pump gas and then add the meth, you may lose a little power. If you optimize your tune with the meth added, you will gain power. It will allow for more spark timing and that alone will pick you up some power. There are safetys you can add in the tune if you place the IAT sensor behind the stream so timing will be removed if meth fails to spray for any reason.

E85 will help with the octane, but IMO, you're not going to get the cooling effect due to the proximity of the injectors to the intake port, which will reduce the fuels' ability to atomize and exchange heat. You'll also be forced to contend with the injector sizing and fuel volume issues to accommodate the increase in demand of the E85. Then, for some, there is the lack of a good # of E85 stations in the area.

I've got a brand new Alky-control kit I'm going to install soon and was wondering the best place to mount the nozzle? I'm wanting to use it for safety so do i mount it behind the MAF( integrated IAT sensor)?? Is there a need to retune after the install if mounting it like I mentioned? I have been told it will run real rich so i will lose a few hp?? Please enlighten me as well!

You have a 5 wire MAF. You can remove 2 wires responsible for the integrated IAT and buy a 97 C5 IAT, pigtail and grommet and put it down stream. I placed mine in the intake, just behind the throttle body.
Since Meth is acidic, I wouldn't place the nozzle before the MAF. It will cause problems eventually.

Take a close look here. You can see my (2) brass meth nozzles on each side of the intake pipes and the sensor in the black rubber coupler just before the throttle body is the relocated IAT sensor

No E85 around here. For me it's like race gas on demand. Great for a street car that spends about 95% putting around in traffic on 92 octane. Only uses the good stuff for maybe 5% when I'm hittin boost. With meth I can run over 13psi with stock 10.5 compression.

I use meth only to cool my intake temps... if I dont I am getting to 140 above by the end of 3rd gear... The engine is tuned for gas only but when it starts to spray you can feel the car liking it...

BlownBlueZ06 and Corvette-Chris,
Basically, what your saying is to cut the wires that go to the IAT sensor in the maf, splice them into a new pigtail harness and into a 97 C5 IAT sensor, mounted downstream of the meth nozzle?
Since I have an A&A kit, can I move my maf so it's just above the Intercooler and then mount my meth nozzle in the hard pipe after that and then the new IAT sensor before the TB? How hard would it be to mount it in the intake? Will I need to retune after if I'm using it for safety? Can I install the IAT sensor in the rubber coupler before the TB or will it leak boost?
Anyone have instructions on which wires to cut as well as the part numbers for the IAT sensor and pigtail harness? Why is it recommended to run a 50/50 mix and not just straight meth?
Thanks in advance for all the help! As you can tell, I'm a newbie to meth as well!

Would Methanol add anything(hp-wise) to a High compression/427 engine? I know i would need a tune for it, but would there be any benefit? It runs strong on 93-octane with this tune.
How about if i ran a 125-200 shot of Nitrous + Methanol?(on my 427) Thanks In Advance!

Cut the Tan and PPL wires off and splice them into the pigtail.
There is no polarity, so just pick one.
Motley Drew and I put our IAT sensors in the intake behind the throttle body.
I wouldn't put it in the silicone coupler.
