water meth question

Has anyone tried water meth? I'm running a twin turbo p pumped 24 valve. I have the air and still have plenty of fuel left to squeeze out but haven't because I wanna keep the egt's down. How much would water meth help. Id like to stay away from nos and propane only because I think getting a lot of power out of just fuel is more respectful. Not knocking on any one that uses spray but its just not something I'm into although the 1200hp numbers are awesome. Just looking for some input. Also if it is a good idea who makes some of the best kits. Oh yeah I use the truck as a daily but I drag and dyno with it too. Thanks .

My truck:
1999 Dodge 24 Valve Cummins
P pump conversion with a 180 pump
Pump doesn't have a fuel plate, 4g springs, & full cut dv's, no afc, ect..
.093 fuel lines
Air Dog 165
custom ground cam
mahle pistons with .050 valve reliefs
balanced rotating assembly
8 x 11 injectors
ported head with 60lbs valve springs and 12mm studs
Pro 52
Polydyn header
stage 5 east coast diesel bullit automatic trans.
triple disk dunrite torque converter
4.10 gears
klienn train horns
Nubers with the twins and without header

Looks like you've already addressed the head. That is the main issue that I have seen with water/meth is the increased cylinder pressure leads to head gasket failures. If you are just looking for cooler EGT's I would consider just doing water injection. No real power gained, but it will cool the air in the intake.

From what I hear water meth wont help EGT's Unless you are spraying mostly all water. But spraying mostly all water wont get you much if any more power just cooler EGT's. Spraying a healthy mix of water/meth will get you more power but not lower EGT's & higher drive preshur. But again this is just what I have heard.

I see Robts is running it, and he seems to have one hell of a set up. Why don't you PM him and ask? I was considering the same thing from Snow performance mostly for the MPGs. Good luck, post your results.

The main head issues stem from the meth which is used as a fuel, more bang means higher cylinder pressure, which puts more strain on the head gasket. Water injection cools intake air temps, resulting in air with a higher oxygen density. Higher oxygen density, means either lower EGT's and lower smoke. If you do this, just to allow yourself too run even more fuel, then you may end up having to be concerned about your head still. What are you currently running for fuel and boost? What is your current set up like?
