Twins guys-- why no intercooling between stages?

[paulb]

On thing to keep in mind is that the goal is to remove as much BTU's of heat as possible from the air going into the engine. An intercooler will remove more BTU's the greater the temp difference. As far as intercooler efficiency the hotter the air moving through it the more BTU's it will remove, with the same outside air temp.

but those BTU's and its effeciency is tied to the CFM's you're moving through it. those units are way too small.



what happened to the K. I. S. S. idea, rather than turn you nose up at the tuner guys next time you're around them why dont you look and see their little setups they use to spray their IC's. most use CO2 but some use NO2 and just fog the outside of the IC to cool it. cheap, it works and its simple. trigger it with boost or throttle position and you're set.

Exactly.



And the hood scoop inner cooler is an awesome idea. The only thing is someone/company needs to fab up a hood and inner cooler combo to make it look nice and function. How the air exits would be interesting, I have never looked at a WRX that closely to see how this would.



And to lower the cost of this. Since very few people do the twin turbo, well, on the 3G's not many. mainly 2G anyways. I would venture to suggest a dual innner cooler setup for _single turbo_ applications. The majority of the work involved to design a scooped hood should be the same for twin turbo, and single turbo applications correct? The difference would have to be in how the innner cooler is designed with air inlets and maybe outlets. One could adapt this hood and inner cooler to be in series right after the main cooler prior to the intake manafold. I'm gussing 80% part and design reusage to do this. this way, all setups could benifit from a second inner cooler.



And now you can say, "yeah, that scoop isn't just make make my truck <b>look fast</B>, it helps to make the truck faster.



If anyone does this. I want 1% or 2% of the profits!!! or atleast my name involved.

We did the between turbo intercooling back in 2001 on our Silver race truck. Infact right now we have a shop truck that also has this setup with our twin kit. It works well the kit is pretty time consuming as their are a couple of caveats. But we dropped over 125° in EGTs just cruising on the freeway.



The intercooler is a water to air unit, with the piping pretty much done nice and neat. We were going to sell a kit but I'm not sure how much demand there would be.

 

[swankmetal]

would it only work with your company's set up?

We did the preliminary setup to work with ours and PDR's. It may work for others but I have not seen that many to confirm.

why not a small custom made evaporator to be plumbed into existing A/C system sorta like the heater block under the intake horn.





better yet take an old small chest freezer apart and wind the cooper that would be found wrapped around the chest around the cold pipe, put the compressor part in the bed and run off of an AC inverter when the pipe is compleatly covered in frost you have cold air enough to get at least spooled for pennys and no obsrution to air flow, sept maybe frost in the pipe :-laf ... call it the sanford and son special

So here is a question to ask on this thread! If I'm at 85 psi and the air temp at the hat is 105 F, do I really need an air to water cooler?



Now lets set back some 2 years. Doug Mangrum (NMRA/FFW type) has a procharger blower car that runs in the 6's, his intake temp going through the lights is 100-105 degrees F. So Mike Duffy builds a huge(bigger) intercooler, piping ect for Doug's car and now it goes through the lights at 60F, what does he gain... ... . nothing, no E. T. no MPH! I'll stay with my bad boy intercooler and my water injection and drive it 350 miles a week!

Take a look at an ACERT Cat C-13 and up in a truck application. A water to air pre-cooler is standard fare, and their aren't that awful big... ..... too bad the only ones lying around at work would inject coolant into the air.

that wouldn't be so bad

that wouldn't be so bad if the "coolant" was water/meth would it? maybe that wouldn't cool too well but if you put freezing cold water in the water/meth tank it could be benificail.

maybe you could do this but instead rig up some king of co2 system to circulate through it then vent to the atmosphere out side of engine compartment where it wouldn't become an inert gas. (this i would like to try some day. )
