? about Snow Meth Speed Inc is running a GP, so I thought I'd ask some questions. (Ryan?) I know it cools the intake charge, but does it result in lower exhaust temps too? The reason I ask is my ceramic header coating is blistering, and most of my exhaust is discoloring - which tells me my exh temps are pretty high.
Since I'm only running ~7 psi & 18-20* of timing I'm not supposed to need it. But with my IAT not displaying on HP Tuner, and no exh temp gauge, I'm a little concerned. Would this help me, or be a waste of $?
I'm not really looking for more power, I just don't want to hurt anything.....

**pops head in**
you probly have, but......have you stuck a wideband on it? if you think your exhaust temp is that far off, maybe your fueling is also off? or the timing is too retarded and the fuel is burning in the header?
timing and fueling have a huge effect on EGTs... and if you know your EGTs are off, then one or both of thoes are most likely off... and on a forced induction car, id look into it until i found a solution...
i know its harder for you to do that then it for me to talk online about what you should do, and i hate being "that guy" just talking about it online, while you actually have a 10sec car... but i just thought id say something anyway.. its probly not news to you, but i know sometimes i need someone to state the obvious to me too... lol.
maybe you'll be lucky and its a simple fix... or its not the motor, but the coating failing.. in anycase good luck...

It will kool the charge and add fuel and power at the same time. I also cooked my headers when I had the blower on it. More power more heat. We will have to spend some mre time on yours with the Wide band 
BTW Pick up the phone! LOL I need a kit for the truck!

I run about 36* total and back off 8* with a 200 shot. What happens is the mixture is still burning as it exits the exhaust port and puts a ton of heat in the header. I'm sure your EGTs are off the scale.

I guess it's kind of a catch 22 huh Don? With boost, you can't run too much timing and you have to run rich to avoid detonation (if you like your motor). Which as you point out results in fuel still burning in the headers. And then add in some race gas that slows the burn process down even more, and I'm surprised I'm not shooting flames out the exh tips. 
So the question is would meth help? It will cool the charge, which should allow me to run more timing. Seems like I could also lean it out? I don't want to run it so hot for so long that I start burning exh valves or seats. But if it won't do anything, I'm pretty sure I can find something else to spend $400 on.

Testing.... Testing.... Testing.... Testing.... Testing.... Testing....
LS1's don't need much timing...due to there very efficient chamber design. If you run any car advanced over what it needs your going the wrong way....As for timing a lot of blower guys run down to 10 degrees total (depending on boost and IAT').. Your in no way to low on timing and your wide band numbers looked good....The answer is to pull the blower off and run less exhaust through that combo..... or just not worry about something that does not need worried about....

I think the meth will allow you to run more advance safely because the charge will be cooler. So it helps in that sense, and also the expansion of the water/meth in the chamber gives you more power as well.
I can already tell you that Snow kit kicks ***...Ryan runs 3 degrees more with it....Total of 20 with snow....17 without.....At 15 psi.... MARK, I would just install for the extra 20-30 rear wheel, guys are claiming in on forced induction applications... 
DON...yep, it's amazing how some of the bigger forced induction guys run very little timing...I know on Cory's setup, we had the timing down to below 14 at WOT...After some heavy tuning and more fuel we were able to get to 16-17 at WOT....After Cory pulled the cats and put in bigger heat exchanger (along with an AFR around 11.5) we were able to run 20 degrees and used the IAT table to pull timing above 170 degrees....That way we had the most timing, and if it ever had a prolonged pull up a grade the timing would retard a little (besides knock sensor circuit).....Some of the Stroker NA guys are seeing best power at 22-23 degrees....Most "Stock Cube" cars make most power between 26-28 total.....DAMN LS1's ENGINES...

I too have the IAT issue it seems. I tried your trick Jim & got 21+ at launch, but it quickly drops back to 18. So maybe the Snow Meth kit is what I need. On my other 402 (I used to have a bored 396) I ran 40-45* of timing per Grumpy's intsructions. (not Ellis, the REAL Grumpy) You'd NEVER get that out of an LS1. I ran 28* on my cammed stock motor. Any more & I'd get KR.....

Seems like that's a popular LSx thing to do with the ATI procharger! And then you will get to lose the license plate and have a bitchin FMIC showing through. I bet that plus meth injection would give you a substantial increase in power

I was hoping I didn't need it for this mild setup I'm running now. Thing is, everytime I look at my setup, I see some way to improve it, or find some item that I think is hurting my performance. And then there are all these issues like Meth that I just don't know enough about. Not to mention tuning. All those little tables I used to ignore play a much bigger role now....
The Meth kit is good for a lot of people. Just make sure you mount the reservoir lower than the nozzle or use a check valve. A few guys have had issues with the low end meth kits seeping into the intake system.
If you do your homework on the forums here you'll be very happy with the kit as long as you don't go super cheap
