Ive had a few different alky injection companys tell me different things that didn't exactly pan out. Don't get me wrong I do you them as added protection on customers street cars but they never delivered what was touted by the SALES MAN. Remember they are trying to sell you something. Are you able to log pre and post temps?

I will use straight meth as I believe it will evaporate better than water and hopefully won't impact the impellers as hard.
I wonder how much will be released under the hoop when the BOV opens?

same here, i think i am going to give it a try. this is on my old rat rod that didn't have any space for an IC without cutting the original grill.

Ok well i run on the street with 10.5-1 comp. and run 10 pis sometimes 18 and see intake temps on my 5th dyno run of 65 deg's you can keep your beer cold on the intake during a run lol.. on the street on the highway in cold weather it dont work too well as my carb will frost up and freeze.... it can be done but E85 or full meth is needed.. I think all forced fed cars need some type of alky to really to run to the max!!!!

back from the dead, a little update, the ebay 4inch on 15psi sees 117* intake temps, with the alky turned on it sees 90* temps. I am switched over to E85 and what do you guys think the temps will be with dual 14 AIS nozzles and no intercooler? again the cars a 408 s91 with 18-20psi max.
...ps, problem is the car runs hot and i want to get more cold air into the radiator, the dang intercooler blocks everything it seems.

temps were 90* with meth and intercooler. i am debating on how high the temp would be without the intercooler, seems like the pipes heatsoak might be doing more harm then good, it is just a cheap fleabay intercooler 4inch diameter, 3inch in and out

I have a pt88 with stock radiator in stock slanted position on a 408. It stays around 180 - 190 when cruising around. Your temp problem is most likely from not running the piece that sits under the radiator. The air scoop is needed to keep it cool.
What are you running track wise an with what boost?

If this is a pure track machine, have you considered going A2W? Alternatively i can post you to a thread of a guy useing dry ice to great effect! 
LASTLS1, i think its Q16 that like hgiher intake temps than C16. problably something to do with the energy required to get the fuel to start burning.

I had a 15 gph pre turbo nozzle & a 4 gph pre throttle body nozzle. I had my timing set around 15 degrees. I was running 91 octane & when it shifted to 3 rd at WOT at around 11 pounds of boost it popped twice & shot the dip stick into the sky. It pre ignited on cylinders 1 and 4. Cylinder 1 busted the mahle forged piston and split the block all the way though to the water jacket. Cylinder 4 just chipped the piston. I have it back together & running with 2 new pistons & a steel block. Could'nt find an another aluminum block. I am trying to plumb the intercooler as we speak. It is a PITA.
