Dry kits cannot backfire, there's no fuel in the intake to burn.

Does anyone know what the fuel (alky) pressure should be to use those jets?

This might help explain it. http://www.turbobuick.com/forums/showthread.php?s=&threadid=104469

Its because of the low pressure. When you inject water into an area of lower pressure (your KB inlet) the water vaporises much faster than it normally would at a higher pressure. Since it vaporises so much faster it removes the heat in a shorter ammount of time. Thus your cold inlet pipe.

I was reading through some SAE papers on water injection and found somthing that might explain why alky almost always works better than water for the intercooled TR. From SAE paper 1999-01-0568: This would explain why pure water works better for hot air motors and is less effective for...

Has anyone ever datalogged ACT's with nitrous? Im thinking about adding a 50 or 75 shot to help spool the turbo (hot air) and was wondering how much it will drop the ACT's.

Since the water is in solution with the alcohol its freezing point is going to be much much lower than 32* F (which is why the Crown in my freezer doesnt freeze), which brings up another point. What if I were using mostly water with just enough alky to keep it from freezing? How much more...

How much more effective would the alky be if I were able to pull its temp way down before injecting it? Like putting the alky in the freezer over night, or packing the tank in ice etc. Anyone ever experimented with this?

Well what about C16 instead of alky? Im just trying to get around the tuning issues with the alky injection, turn on point, pump presure, nozzle size and have more control over my fuel supply with my computer.

Instead of injecting more and more alky and less and less gasoline like a lot of people are doing, why couldnt I just build a separate fuel system for alky that was activated under WOT? To completely shut off the gasoline to the injectors and supply them with 100% alcohol? You would need a...

The higher the barometric pressure, the higher the boiling point is. If you pull a vaccum on water, it will boil right in front of you and will eventually freeze too if you have enough vaccum. Whether the barometric pressure has an effect on its latent heat of vaporization I dont know, but it...

I dont think that knock suppression behaves the same on each and every combination. You have to take into account all sorts of variables like air charge temp, EGT's, combustion chamber design, the shape and speed of the flame front etc. I think the fact that the TR's are already intercooled has...

Did I read that right? 30 degrees below zero?

This doesnt answer the question, but I know of a mustang with a Kenne Bell injecting straight water before the blower and was able to add 6 degrees of timing with no other changes. You can sit here and argue about theories all you want, but 6 degrees of timing is about 50-60 hp. Who cares...

With discharge temps around 250-275 which would suit me better? Just because the temps are lower with the alky does that automatically mean that it will be more effective at reducing knock than the propane at a higher discharge temp?
