I was doing some searching and came across this site http://www.designengineering.com/index.asp . Looks promising and seems like it would fix alot of our problems with cooling. I don't know anything about co2 and the drawbacks involved so your feedback would be greatly appreciated. Also on a side note they sell a intercooler water sprayer for only $94.00 . Anybody know if thats a worthy mod, and if so could you use that at a track without leaving a puddle and getting kicked out?

 

you are lucky to get 10-15 seconds of spray out of a 10lb tank
when you spray your intercooler/heat exchanger you run the very high risk of sucking the co2 into your intake which results in less oxygen and less power
a 10lb tank fulll of co2 is very heavy so what tiny bit of hp you gain is offset from all that weight

it is very impractical since the tank is emptied so quickly and you constantly have to fill it up.

it is a waste of money but if you are set on getting it there are other companies that make similar kits for about 50% of the cost.

 

water/methanol injection would be about 100x more effective.

 

I agree/disagree you can get a 30lb cannister and a wand and spray the heatexchanger between runs and it will drop temps way down, like under a 100. and with nothing to mount and no installation it's actually pretty cheap.

 

On an air-air setup it works well.

We have an air-water system which isn't optimized for such a setup....the intercooler in actually UNDER the supercharger. What you see in front is the heat exchanger.

 

I know its an HE and not the intercooler, but was just wondering if spraying the HE would work also. Thanks for the info everybody.

 

alcohol injection is much cheaper in the long run and it works all the time as opposed to an occational spray from the co2 (again it can hurt hp when your intake sucks in the co2) also alcohol injection can make MUCH more power by increasing timing and you can run a 12% nitromethane mix in the meth to gain even more power. the alcohol inj can cool intake temps by as much as 250 degrees, much more than the co2 will get you when you spray your heat exchanger. honestly the cryo setup is mostly just for show, it is a waste of money. most people that get it use them for car shows or just to purge to "look cool"

 

I'm not saying you didn't, but those sprayers are for an air-air setup.

An air-water setup is approx 14 times more efficient at transferring heat from the liquid to the HE than an air-air setup. The additional atmospheric transfer, assisted by the CO2, is only minimally aided.
IMO, you would be better off with an ice reservoir for the coolant and separating your IC system from the engine coolant.


Please be careful spraying any liquids into the Kompressor. It is meant to be a dry setup.

 

Please be advised that the carbon dioxide coming out of the tank is cold and can immediatley destroy the heat exchanger due to freezing. Giving a blast of CO2 is about MINUS 109.3 degrees and that will freeze the antifreeze most quickly. If you want to cool it off without the cost, use a leaf blower, I used one with a water mister and it was very effective at the trackwithout all the water on the ground, tires and such. Leaf blowers are several hundred CFM as long as you want to run it and it is cheaper to refill. Woody

 

Please post links to the best heat reducing kits, whatever the type. The difference in performance between hot and cold on these motors is night and day. I just want to find the most cost effective kit availible to lower the temps efficiently.

Is a bigger electric fan, lower temp thermostat, and spacers the only real options?

I know after tearing up on the ride for about 15 minutes, you can just feel the heat and know it's real hot.

All help appreciated.

 

the internal bulbs they make look very cool, i have one here on the bench we were playing with, it would gopefectly in the middle of an intake, i just havent installed one yet due to not wanting to loose the trunk space

 

You would probably get better results in a N/A Crossfire.

The adibiatic heating from the supercharger would quickly raise the air temp. It would be more efficient to install post-supercharger, pre-intercooler. Packaging precludes this.

I think a larger heat exchanger and upgraded Johnson pump is the best bang-for-the buck.

If you can swing it, a reservoir in the trunk large enough to run ice could put you well on your way to the 11's.

 

Problem who sells that?
Lots of we will soon on the web but I haven't seen one yet that I can add ice in my trunk to.

Or am I dumb.....clue me in where to buy and it would be in my trunk!
