Water/meth injection required?
My IATs are around 95F on a hot day which I think is resonable, about a 10F rise. But due to the humidity, we all know that the less dense air kills performance. I was thinking about installing an injection kit and would like to know what the trend is? I am still under 9psi but I would think that lower IATs and better volumetric efficiency would help under all conditions?

What fuel are you one? Intercooled? Tons of other variables.
I'm on E85 non intercooled. My IATs are about 190* as I hit the 1/4 traps. That was spraying a 50/50 mix. Next time out I'm spraying a 3rd nozzle and straight meth. I say if you're worried, spray it. It's not too expensive, and if it'll make you more comfortable at WOT, go for it.

I really doubt the tune is pulling timing below 100*. Spray some blue washer fluid at it, I'll bet it won't feel as sluggish in the warmer weather. And it'll make it that much safer.

Not sure about the blue washer fluid? I buy methanol and mix it 50/50 with demineralized water, this is the only intercooling I have for my 4.3 supercharged Jimmy. As for the T/A, I agree that it wouldn't hurt to get some latent heat transfer going on and improve density as well! What system do most use for the F-body? Not much space!

Ok, I'm running 91 and twin 4.5 ICs. Not running at the track but really notice the power loss with heat and humidity, I know this is normal for FI. Was thinking of water/meth as a compliment to the system under normal driving and of course WOT. I know the IAT sensor has a lot of authority so I am sure its pulling timing?
also as said, your timing really shouldn't be effected much, if at all with 95* IAT's, unless that's only what you're seeing at cruising vs WOT pulls?

More of the same. If your are seeing IAT's under 100, I honestly think meth injection would be a waste of your money. You shouldn't see any gains at all with that.
Now, if you plan on upping the boost, and or timing in any significant amount, then I would say you should re-visit the idea, but until then I would leave it as is.

OK, that's good to know! I should clarify that my IATs are at part throttle and around 4,000, I am logging real time so I really need a copilot! Still tho, FI really suffers with heat and humidity and the IAT sensor would have to see that and pull timing, it plays a big part on LS1s. What systems are you guy's running? I see Snow system, I have a Cooling Mist on my truck. I am thinking boost will end up around 9 with the 3" pulley I have on the SC now, depending on where the limiter is set. I am currently tripping at 5,700 to keep it safe untill I can get some decent logs.

I am running a snow performance kit. It has worked great for me and the customer service from them is excellent. I know a lot of guys go with Alky Control, but I did not find Julio's customer service to be that good. I will say that Alky Controls kit is also top notch though.
There are others that are used such as Devils Own and others but Alky Control and Snow Performance are the two most popular.

It took me a little while to do this thinking I would need the windshield washer tank, but after I realized I still had the original washer fluid in it, I decided I didn't use it enough and it was an ideal place for the meth.
There was plenty of room for the pump as well.

I plumbed the windsheild washer tank and just used that for the meth resevoir. I even plumbed a sensor near the bottom to tell me when the meth level is near empty.
