I have the Aquamist HFS-5. Now I'm trying to figure which meth to go with. I have been stuck with the choice of either the VP M1 or SP Boost Juice(49%meth, 51%water).

I have read so far, that the 50/50 mix cools better with less chance of knock and last longer then meth. anyone with experience with both?

 

I suggest you experiment yourself. 50/50 first, then 80/20 then 100% straight. See if your car works better with advancing timing or less timing lean a/f. And what you feel gave you the best results.

A good target a/f with meth in general would be 11.8 conservative to 12.0 across the board. If you're confident enough you can lean her out even further and venture to mid 12's. Be careful and make sure your failsafes are in place and working

I would go with who ever is cheapest once you mix the vp down to 50/50 mix with denatured water.

 

Distilled water

 

bump for some more answers.

 

In my WRX, I ran VP M1 mixed with distilled water 50/50. I had no issues with that mixture.

 

As said it is up to you what mixture you chose. It takes a little bit for the water and meth to fully mix (an hour or so can't remember). 50/50 will not catch fire. I use straight meth so I don't have to worry about the mix. I also have found it to make good power. The more cc the better to an extent. You will have to weigh the pros and cons of each. Hell some use 100% H2O.
