Competition air-water intercooler, worth it?

[F8LDOSE]

I was thinking of making a new upper intake which would be the whole length of the base plate, this would involve making new injector lines,. The manifold would would be much larger than stock, and would probably have ten times the space inside. Then i was going to put several runs of half inch lines inside and pump ice water through them, used in addition to my stock air to air cooler. Is this a good idea or am I wasting my time? It would have to drop the intake air charge even more... ...

Unless you make the cooling area like a radiator it might not be effective enough. I don't have the books at home but I think that there is a water to air unit built by Cummins for industrial applications of the 12 valve engines.

I know that I am wading into dangerous waters when I mention this, BUT, I know that in all of Gale Bank's engines for Bonneville he uses water to air intercoolers with ice water.

I have seen a twin turbo small block melt 30# of ice and the water heated to 90 degrees in a five mile run.

dont wast your time makeing one the come on the some of the industral engines all ready you can get them for arund $75 at your local big truck recking yard



I am going to run on on the the lil red cummins express with its on radiator of a bike

Has anyone tried spraying water on the intercooler during heavy use? A friend mentioned I should try this, and I just shelved the idea, until reading this thread.

I guess you could use a water injection type kit to spray a mist across the intercooler. Comments... .

I was thinking about doing this summer but prioritys got mixed up. I have the parts to do it. A complete windshield wsher kit from an early 80's Nissan pick up. Comes complete with reservoir, nozzles, wiring and hoses. I have it sitting on the shelf.

Spraying the intercooler off with ice water definately helps. My buddy runs a twin turbo nissan in import dragracing, and we'll spray ice water on the intercoolers for several minutes before each pass,(using a pump up sprayer that you would spray trees with) the intercoolers, being aluminum get ice cold as well, and this trick really helps him. A little reminder to anybody that is going to try this for dragracing, Make sure you blow the intercooler out with air to get the water out before you launch..... :--) :--) :--)

I saw fairly recently in a turbo-import racer type magazine where they were running a mister spray bar across the front of their intercoolers. Through this they blew some sort of compressed gas which cooled the intercooler.

These are for the 12 valve construction spec engine.

We have been testing a water to air between turbos. So far we have seen a drop in temps between stages of about 50%. We have some more testing to see how it has affected hp. So far it looks promising, we have some more testing and mods to do to it, but it should work well.

The trucks that run at Bonneville with the Detroit Diesels have very large intercoolers between the turbos and the blowers. Then in the valley under the blowers are another set of intercoolers. I have a picture of the set up on Joint Venture that runs 250 mph, but, it is too big for me to post here. I can send it to you or anybody that wants it. Maybe some one can post it here for me.

 

[Pat@BD]

Please email me a pic of it. Sounds like an intersting set up.

Look at the results of this one, cools air from 405* to 119*.

The good part about air/water IC's is that you could in effect get your air charge BELOW ambient air temps if you ran ice water through 'em... something that is pretty hard to achieve with an air/air... unless you spray it with something.



There are even 'intracoolers' out there... . they run your A/C refrigerant through the IC core for a REALLY cool charge. Gassers love these... . but the parasitic loss from the A/C compressor has to be realized and overcome... .



I have experience with air/air and air/water... . they both have their place.

I have often thought about taking the vent that runs to the FAR passanger side, and running it somehow into the plumbing to the engine for a cold shot of air. Wouldn't this increase boost by just a tad too?



Andrew

 

[HoleshotHolset]

Just remember... too cold of an intake charge isn't good ... . diesels being compression ignition rely on a happy, not too cold air charge.



I doubt you'd see more boost.

I know, but it's the thought that counts right?

There's a bit of a problem fitting the Cummins water to air cooler. It seems it was designed for the 12v engine.
