Ok, that's either a complete fabrication, or misrepresentation.

There is NO WAY you saw 20F intake temps on a 104F day without ice in the reservoir.

That is a COMPLETE misrepresentation of a closed loop A2W system.

I already said though, for a drag car with ice in the system, hell yeah it's the way to go.

 

Heat exchanger (radiator, for the dumb asses) two 1250cfm fans (2500cfm, if you don't know math) just over 8gal of cooling media (distilled water, sea salt, water wetter) and nitrous to cool down the media if i feel it is getting too hot! As i said before mine is not a typical air/water kit! sea salt helps keep the water from freezing until -4* with the mixture i have.

 

Have you had any experience with air/water on a vehicle? Besides a drag car!

 

Ok, sounds like a slick *** setup.You've come up with a way to induce an ice reservoir like setup using nitrous. I'd still argue the nitrous would do more good in the motor though.

You say A2W and below ambient temps and I'm calling bull**** unless you add an additional cooling media.

I don't have any experience on a street car. Like I said, wrong tool for the job. I've done enough math to know a simple dual heat exchanger closed loop system does not beat out a good A2A though.

I do have some experience on an 800HP drag car though.

 

I did say mine is not typical, I can create ice in my reservoir. But most air/water systems are pretty damn good as long as you can sink coldness, you're not in the boost all the time, after i get out of boost,my temp drops almost instantly.

 

An A2A that is properly designed can pull the charge down to a couple degrees of ambient. The A2W isn't going to do any better than that without additional cooling like what you have done.

An A2W can have substantially less piping and volume for better response, a definite plus.

An A2W is considerably more complicated and heavy though and that's why I steer clear of them on a street car.

 

I've had setups on bikes and cars! street and drag! The only time A2A is better is on a long road course, like MMP, but you just have to think outside the box to keep your temps down. The best you will ever get with A2A is ambient, unless you add an additional cooling media, it takes alot longer to heat up the water. It is only 14 times more dense than air!

 

A2A will always have to deal with pressure loss also! A2W not so much, I lose less than 1/2psi thru my intercooler, how many A2A can do that? None i have found!

 

Weight and complexity man. Even on a race car.

Every pound you add is a strike against the setup on acceleration, cornering, and braking.

Every bit of complexity adds another point for failure.

Pressure drop is pretty easily made up for. We have a turbo to take care of it.

 

I agree with you on weight, the only thing i have to worry about failing is my pump! Our cars already weight a ****load, I did my setup for me, because i can't leave nothing alone, and I don't trust others to test for me! I know for certain aspects they both have their shortcomings, but I like not having lag, cooler intake temps, EGT's, ONR, and less thermal loading on parts. I think the extra weight is worth the horsepower potential.

 

You are talking to the wrong guy.

I DD a base model EVO with over 300 pounds missing.

My goal over the next year is to pull out another 200-300...

I can definitely respect you mentality though, just not the way I like to build cars.

I think my next setup will it a good mid way between the two. It will be A2A, but it will have very low system volume and be very capable of getting temps down to ambient while being VERY light. Under 16-18 pounds for the entire system.

 

That's the beauty of it, no one has too see eye to eye! I'm in the process of gutting my car, and designing parts to help it drop a ****load of weight! Good luck with your car!!!

 

jason i need a catback

turns out my wastegate was torn..

 

fairclough did you get my last PM asking about some parts?

 

"Hey dude, I'm going on a canyon cruise with Biggie in July. Can you ride shotgun and consistently monitor my post intercooler air temps on my laptop... I hope you don't get car sick easily? You'll have to hit this switch every time the temps go above 40º F. Also, whenever we stop, can you also run into the closest gas station and buy 10 bags of ice to fill the 50 gallon aquarium in the trunk. We'll run out of NO2 pretty fast, but we can keep buying ice all day long. This is going to be a sweet drive!"
