Tank mounting location heat soak concern. Nozzle question as well.

Tank mounting location heat soak concern. Nozzle question as well.
Hello,
I am very close to purchasing the Snow Performance Stage 1 Boost kit. I will be running a 50/50 mix.
I have two concerns:
1) I want to mount the tank in my engine bay BUT the only place I will be able to fit the 3 QT tank is thr passenger corner on the firewall right above the turbo. My engine bay temps are pretty low considering all the heat shielding/heat scavanging I have added to keep the temperature low BUT it is still the engine bay which will get warmer then a rear hatch mounted tank . My concern is will the higher temps hinder the 50/50 mix performance......hotter mixture - less cooling effect?
2) I HAVE SEARCHED and have read many of Howards posts regarding nozzles BUT I have not found if there is a perferred nozzle position/angle in the intake tubing. I do remember coming across a post that stated the 4 o'clock position is the best nozzle position...is this true?
Anyway, the pic below with the red circle shows the only place where I can mount my nozzle due to my Greddy overboost valve( in the second pic, the first is better clarity but was before I mounted the pop-off valve). The green is the tank location (yes all electronics will be relocated along with a heat shield around the tank with an incorporated spill shield to keep harness dry). I will mount the pump close to the tank somewhere in the engine bay(undecided)
pop-off valve pic
Now if I can not find room for the pump I will most likely run the tank/pump in the rear hatch. I dont want to do that because concerns of pressure drop but I may just be parinoid.
Thanks for your time.

Thank you Barry for your advice.
I just got done searching and reading for about 2 hours on everything from pre-turbo, nozzle location/sizes, 50/50 vs H20, pre-filter, no IC vs IC with AI, ect......my head hurts
What I have decided to do is I am going to run a 2 nozzle set up post-turbo imediately after my Greddy pop off valve. The nozzles are going to be 175ml/min each due to better atomization at pump pressure compared to 1 375ml/min nozzle.
After reading numerous threads in regards pre-turbo injection I am comforted that since I have a huge Greddy front mount that post-turbo is the best route(couple of rotarygod's post help assure this). I would like to mount the nozzles immediately after the IC but in case I ever over-boost my WI- 50/50 mix will be vented from my Greddy pop-off valve SO mounting immediately after is the only option.
I read in one of Barry's threads that nozzle location for 2 should be at 3 and 6 o'clock so that is my decision.
Since my boost pressure is only 15 psi, maybe max 18, i am hoping that 350ml/min combined nozzle flow should suffice. Power output I estimate to be around 380-400 rwhp.
Any other input/constructive criticism is WELCOME....do not hold back.
Again my goal was originally knock suppresion but since 50/50 mix has the best of both worlds..it seems the best choice.
