Meth/water injection?

You can also run a leaner AFR with water injection since you can replace some of the unspent fuel that is used for cooling with water, which has a much better specific heat.

VP Racing fuels also sell meth in large 5 gallon drums for $40-50 IIRC. They have physical locations you can go purchase these drums. ^^

I'm planning on using around a 50/50 mixture just to be used for IATs. After doing some math from some Subaru forums and the Aquamist forum, I should go with a .7mm nozzle for the IC and a .9mm nozzle for the TP, does that sound about right? I'm not looking to run crazy boost or tune for it, just want some protection from summer heat.

I'll be running a GTM Basic fuel system with Denso 600cc Injectors and Walbro 255 Fuel Pump. I'm inly hoping for around ~500 whp with low boost.

I would think it would be better to trigger meth based on MAP pressure than RPM, unless that's just a window switch and it's still based on MAP in addition.

Just to follow up on this, I had the Aquamist HFS-3 installed last week and spent yesterday with my tuner. It's working great for AITs, it was 85 degrees yesterday and when the meth was running the max temp was around 100 degrees. My plan to not tune for it didn't work with this system because with all the meth it pumps it made the car way to rich. We ended up doing a second set of maps so I can run it with or without the meth so I'm happy with the kit.
