Should I run a meth kit??
I think they are in the 550-600 range. But they are worth it for that price. You run STRAIGHT Methanol through his pump (best cooling effect). No oil additive or anything. If you cannot find meth, you can even use denatured alcohol off the shelf of a hardware store (expensive, but good in a pinch, also little harsher on the pump). I put the kit in myself in only a couple hours (17 year old mechanic here). Somebody on here is using it in their 580HP procharged LS1 on a stock short block.

No, it's not. It evaporates quicker, so yes, it will give you a lower reading at the IAT sensor, but once it hits the combustion chamber and ignites, it adds to the overall heat in the chamber. Water on the other hand, cools as it evaporates, which is slower at ambient temps, but once it hits the chamber, pulls out considerably more heat, and since it doesn't ignite, it doesn't add anymore heat back into the piston/chamber like methanol does.
Does methanol make more power, YES, but it also adds more heat. On a stock shortblock, the pistons and rings can't handle the extra heat, remember horsepower is directly related to heat. More power, more heat.
Here's a chart showing the difference between how much heat the methanol absorbs versus water...
100% Water is on the left, 100% meoh is on the right.
I'm not opposed at all to running 100% meoh because you will make more power than mixing in water with it, but if you're after a cooling effect, 50/50 is what I would (and will) run.
Remember, knock is also very sensitive to heat, hence why we run cooler plugs.

I stand corrected. I can see where this would be an issue on a car not designed for FI. Buicks don't have this issues, so straight Meth has been great for the IAT reduction, and octane increase so we can run WAY more boost than stock. I myself am running just over 26PSI of boost on a stock short block, while others have seen 30+.
I agree 100% with you. On a motor built to see boost, the rings and bearings have tolerances designed to handle the higher heat seen from a forced induction setup, so running 100% methanol is fine. But on a stock ls1, with rings gapped as tight as 0.009" (mine were between 0.010 and 0.012") high heat from forced induction is a recipe for disaster. The water helps to keep the chamber temps a little friendlier.

so would a 50/50 mix be the best or would something like a 75/25 be better im looking to make the most power but the longevity of my stock short block is more important
and will this help making more power above 600 since i guess that's the reason most stock motors let go

I run 75/25 meth/water by volume. Stock short block beat the **** out of it daily since December. I run two 10gph nozzles.
alky control kit here, but soon ill be running e85 so it should not matter. ill have a seperate 93 octane tune that i will activate the methanol 49/51 (boost juice) in the event i want to drive out of town and cant find any E and still be able to have some fun without fear of temps. IMO the aquamist sounds like the way to go these days per alchemists lessons and research.
