dryice chilled alcohol injection

bruthaboost · 09-15-2002, 02:11 PM

Hello, this is my first post here. I've looked throught the archives and I didn't see anyone address this. I'm about to install and dyno the SMC kit on my integra-I know a lowly Honda-and I'm wondering if anyone has tried dry ice and alcohol (is this worth the extra psi I may be able to run for the cost of running strait alcohol). Ethanol freezes at -114 C and dry ice at -78 C. The two together would of course lower your alcohol temps to -78 C plus whatever heat the pump introduces. Of course I have to use "dry" alcohol. Water would cause the solution to slush. The nice part about dryice and alcohol is that it stays cold for days (at room temp) so you don't need much.

BTW my setup is a garrett t3to4e, spearco FMIC, rc 550's, and standalone ecu. I'm hoping for 360 whp.

TIA

alcohol/water injection works as it removes heat from the combustion chamber when the mixture flashes to steam. I am not sure how the ambient temperature of the injected mix affects the amount of heat removed. My gut feeling is that it is minimal but I am guessing. Should be easy to try.

Remember what happens when you put some water and dry ice into a sealed container. You want to be very sure that the SMC reservoir can breath very well or you will blow the hood right off the car. Keep a camera running!

Hmmm, if you could spray the intercooler, or yes find a way to inject it into the up-pipe, you would succeed in lowering the intake temps. Propane injection works the same way

Tho alchy does cool intake temps by 40 degrees, the alchy (water mostly)cools the egt's by 200 degrees. As Steve has said, this is how alchy injection works.

If you can find a way of delivering a cool, fine mist into the up-pipe you wouls succeed in lowering intake temps, and deliver finly misted water into the intake. That would work!

Of course there is the convenience factor. Maybe a good strong, and insulated container would work. Then you would need a regulater activated by a hobbs switch. Then there would be a slight problem with falling temperatures in the 'bottle'.....

It's actually kind of a neat idea.

Perhaps you could manually spray the intercooler, or into the up pipe. That is to say, use a solenoid, and a simple 'push switch' for starters, just to see what happens.

Yes, keep the camera rolling...

If you don't want to fool around with all that maybe you could position a box with dry ice so the intake would have to draw through it....
