The system in the video is run from 100% down to 20% then back up to 100% and atomization is outstanding for the entire range. We then pulse the system to show the quick on/off capability of the system as well.

Wow, that is very impressive. I'd like to do a project like that someday on a built twin turbo LS 7 liter, but for now I'll only need 1200 cc lol

I had a look around your site - love the twin tanks with LED's.

I run a 15L tank now and it lasts me about 3 tanks of gas on average normal street/highway driving, so going down to 7.5L would require topping up every tank of gas, which could be an issue for long trips away from home. But I love the concept of not having to pre-mix and being able to pour 100% meth into one tank and filtered water into the other.

Thanks Richard, I get it now. This system sounds like what I need.

I assume the HFS-4 has the failsafe built in?

I was thinking of replacing the 2 jets where they are now (pre Throttle body) plus the 3rd one out back pre-turbo - What would you suggest for placement?

Yes, the H4 has an inbuilt turbine based flow sensor failsafe as standard.
