What is a Safe Meth/Water Ratio to use or is 100% meth Safe? Also how much can I boost using meth?

 

This should probably be posted water/alcohol injection section of the forum.

Yes you can run 100% meth or mix for different ratios. It just depends on what you are trying to accomplish using the injection. More water in the mixture will cool the intake charge better than just running straight meth. Mixes vary from 80/20 meth/water, to 50/50 meth/water. Running straight meth will be used to basically up the octane of your fuel so you can run higher boost and more timing. If you are on a stock turbo then should be able to easily max out the boost of the stocker if you are spraying enough meth.

 

I wanna run about 28psi and make about 400 at the wheels or close to it with my full bolt ons. Will I need larger injectors to run meth?

 

No. Meth will make up part of your fuel, so you will not need larger injectors.

 

That would depend on your current injector duty cycle. If you're running cams along with the typical bolt on mods you may need to go to bigger injectors. Log the car to determine whether you need to or not.

 

I run 100% meth and 30-33psi, depending on the weather
