The cars I have dealt with in the past have used air to air and air to water, both with good results.
Air to water can take your inlet air below ambient temperature's(with ice). The weight is a problem in some cases but is offset by the ability to put them anywhere. On same hp they are half the size of air to air. This would be my first choice for high hp cars.

Air to air is cheaper to buy. Biggest drawback is they need constant airflow for heat rejection. I built a 70 chevelle with a AtoA twin turbo big block. It would run around 90 degrees on average when staging, then just under 200 degrees thru the lights. Best et was 7.0X@ 197-201. We boxed up the air to air and sealed it so we could surround it with water and ice. The inlet air temps dropped to about 50 degrees staging and 110 degrees thru the lights. Best et was 6.8X@ 202-205. Then took that intercooler out for a dedicated air to water, it was about 40 percent smaller outside dimensions. The inlet air temps dropped to 40 degrees staging and always under 100 thru the lights. Best et is now 6.70@ 210. Before the run the water tank is filled with ice, 4 average sized bags will fit in. The temps will stay below 100 degrees on 2 bags and 3 gals water. The water at the end of a run will still be cold enough to keep your beer cold for the victory celebration! (or the "I thought I had him" speech)

Wow, this is one of the fastest threads I've seen on here. Great info!

John, that one in the pic is a tank/core combo. I bet the tank isnt more than 3-5 gallons. He made 700rw before this intercooler with a smaller turbo (306ci).

Kurt (Guido) I am far from wealthy,actually work very hard for every penny that goes into the car. I have made a lot of sacrifices of family and friends to accomplish what has been done with my car. I only posted the results of what "I" am seeing with my setup. Is it an ideal setup ?HELL NO but with the knowledge that I had at the time of intercoolers I left it up to the techs at Spearco to build me an adaquite cooler. In my opinion they failed miserbly!This year instead of trying to buy another a/w setup and add more weight to the car, seeing the IATS and what was acheived with those I could only improve the performance of my car with an a/a. Right wrong or indifferent that is the path that I have chosen to go.

P.S . The only thing on my car that I didnt build or assemble is the rollcage!

Chris,

Curt wasn't talking about you....He is talking about your "spokesperson"....I think I speak for the majority that we like to hear information straight from the horses mouth....This "well my buddy with XXX done to his car" stuff is how **** gets turned around and makes the owner of the car look bad....I deal with it on a daily basis....It's old....I have people from everywhere PM'ing, IM'ing me, or e-mailing me asking about my car....I sit and dispell rumors....A few of my personal friends have just ran with it and it has become a inside joke....But I will be the one that looks like an *** because of it....Just because if the car doesn't stand up to the rumors they've heard....

I have respect for both you and your car....I just don't think it is fair that you are being used as an example and have to defend yourself if things go South....I'm also not saying that "he" is trying to make you look bad....But from my perspective thats the way it is looking....

Guido

Yeah Im sorry if I came off like I was trying to make you look bad Chris. That wasnt the case. John took off on one of his holier than thou rants. Youve been around him long enough to know how he is. Youve been nothing but respectful to me since Ive known you and you should know I hold nothing against you. John on the other hand, has no place posting some of the garbage that he does.

Hey Kevin last i heard that Pontiac bigblock with a 106mm was coming along well, how long till its track ready without an intercooler????

Keygan, you're not to far off with the local rumor mill....LOL!

Ian

What kind of ET's will you see with a 1400hp 3rd gen?

BLU BY U

None, it's a street car....

Lol!!!

What was your intercooler setup Curt?

Trvln Nalzmn

Think of it from this perspective. All the energy in the air actually comes from the turbine, which comes from the exhaust gas leaving the motor. If your seeing 1000hp at the wheels or flywheel much less than that will be getting put into the air by the compressor.

If you work out the energy that it takes to heat 5 gallons of water from almost frozen to boiling point you'd have to have a motor making thousands of horsepower probably top fuel power output to do it in the time it takes to do the quarter mile.

Big Stick

Well about 1,000 hp...

rounded:
40lbs water/ice X 180 degree increase = 7200 btu's needed
1hp = about 42 btu /minute or about 7 btu's in 10 seconds
7200btu's /7 = 1028hp

Btw, yes, I was bored.

Guido

My intercooler was made of the two cores that form the 2-230 core. Its listed as a hi performance street intercooler. It was good for me at the time.

that works great if you're using all that horsepower to heat water, not propel a car down the track..

bottom line..

was Chris's (Z8's) a/w inefficient?? YES...

Chris's statement regarding ice water turning to hot water after a 1/4 mile is 100% the honest to god truth... There were a number of things not right about the setup... Cores were small, lines were small, pump was small... in the end, it suffered by the 200 IAT temps at the end of the 1/4 mile...

We believe the weight saved with the a/a and the physical size and CFM rating of the a/a will benefit the cars performance.. we went 159.64mph with 200 IAT, cant wait to see how it does with 100 IAT's..
