It's indeed very strange that they still don't tell about the thermal efficiency of their units.

In January last year they also told me they would have data available by Spring - but that was Spring of 2008...

Sounds like one of these along with RiceRacing's no intercooler AI setup would be a good compromise to no intercooler at all.

 

Back from the dead.

Does anyone have new information on this?

 

First time I've seen this thread. Seems like one 10" or 12" unit could fit between the intercooler outlet and elbow into the UIM.

Seems like water injection would trump this though in terms of cost and effectiveness. I am definitely a big fan of water to air intercooling though.

 

I'm really interested in this as well...anyone ever find out any more info?

 

Kind of pointless with AI, added weight also. Plus there not to cheap so not a lot of people are willing to just try one out for ***** and giggles.

 

Just a thought. I'm thinking about upgrading my stock IC just for a reliability purpose. Do you think something like this would out perform the stock IC in a focus of HP levels in the 300-350 range?

 

Just keep your stock IC and do a water injection system. It will do more than an upgraded intercooler and will cost much less. That is what I did so of course I favor that route.

The other thing you could do just install one of these tube air/water intercoolers in between your stock IC and the elbow.

I still say water injection will trump it though.

 

looks cool and all...

i have only seen this setup used on full out drag cars ..that do one pass ..then they are turned off until next pass .. running on alcohol or methanol at high boost...

i never seen any one... use one on the street...but as i came to find out in this thread ...some high end exotic cars use it.....

so i dont see way it wouldn't work for a street car running low bust ...
lets say single turbo rx7 gt35r at 15psi ....or a larger turbo at 10 psi... for around 350-400 max rwhp range

i think it would work best with larger turbos and low boost and methanol injection for street...

i would definitely use two pipes instead of one ...and run a separate radiator for it...and use 50/50 antifreeze with it ...

benefit of this-- simple piping ,faster response,you dont have to relocate radiator,,
or the battery...

so i say 400rwhp max rotary response machine would work with this setup for street
mostly do to methanol injection....

but .....

if you wanna get in to some crazy numbers 450 or 500+rwhp on rotary with this setup one the street or circuit racing....i dont think it would work....you would pretty much need another 3row radiator in the car to cool the pipes...

this is primarily full out drag racing stuff not really for the street or auto x or circit...meant to cool more efficiently for short period of time

 

I like the idea a lot but seeing as we don't have any real numbers and the examples we do have it doesn't seem like its worth it to dump all the money into it. It was a good read in the end. It does have a lot of "WOW" factor to it when you see it all setup in a car.

 

I am curious though that you could always run a setup like below. Which would be Turbo-->A2W-->stock intercooler-->A2W-->TB. You definitely wont have any cooling issues on that route.



I am intrigued though on running a split dual like they did on this other porsche.





Doing something along these lines would help as well.



I would only run 3 hoses in and 3 out though. Running that many hoses from 1 split just kills your flow. You could do 2 pipes, back to back which would give you better cooling (IMO) then 1 long pipe.

 

idk how much you know about porch 944... but what you see there is setup with stock turbo...
944 makes about 247 hp ...so it would work for stock rx7 to... Turbo-->A2W-->stock intercooler-->A2W-->TB...

you wouldn't gain anything, it just might look cool....and you would have to much going on in engine bay...

you are better of just adding methanol injection and greddy elbow.....on the stock car....should be able to get 350 with pfc and tuning ,,,,

when you add A-w there is no need for stock ic,,,,, it would just defeats the purpose as you wont gain any response or make it worse than it is ...

and you only need to run one hose in and one out ...the pressure from the pump will do the rest...

with that mods are you trying to run this setup....

 

No doubt running this setup with barely any mods is a waste. But you could potentially push more HP with a stock intercooler when you run these A2W units inline as well. Sure it costs more money, but to some people they want to gloat about how they triple cool flow.

As for running multiple hoses in and out. It really depends on how the water flow area is set up. If the coolant can flow freely through the whole unit from one hose you would still find a hot zone on the opposite side of the hose intake.

From my understanding of water cooling capabilities and my experience in water cooling electronics: Faster flow on small cooling area or slow flow on larger cooling area = same cooling capabilites.

But again, it would be a huge waste of money on a stock setup.

 

The whole deal is cost prohibitive if you consider that you can achieve better results for much less money. It does look very cool though.

It seems like a lot of work running any kind of air-water intercooler when you can have direct contact between the air and water by running water injection.

If air-water IC is better than air-air, then direct contact using water injection comes out on top by far, plus it's proven, can be done for well under $500.

Again, it looks cool but for those that already have a nice SMIC or FMIC, adding water injection would do much more than just piling on additional intercoolers.

 

totally agree with adamrs80....

you can buy methanol injection kit for 350$ from AEM

running this pipes with stock ic is just waste of money and time

because methanol injection is way more efficient
and installation is more simple ... some shops will install and tune it for 500$ including the unit ...
-------------------------------------------------------------------------------

now if you are interested in only cooling your stock rx7 with stock ECU... one 10" pipe it
should be better than your stock ic ...

if you add to may things inline you will kill the flow....and response time

by running one 10" you will get the cooling you need and better response ...

I saw a custom one once, worked extremely well! They modified an air/air IC sealing up the ambient air area, filling it with some type of wax that melted at 50C or so and leaving some air space for thermal expansion. At testing they found that the phase change pulled lots of heat out of the air charge and since they used a huge core the wax never melted completely and went back to solid when off-boost. Charge air never went over 50-55 C.

Only thing is that they could not use a lower temp wax because it would be liquid at ambient temps and they would lose the phase change.

Cool looking and easier to incorporate into your system, but not every efficient. Doesn't come close to the regular a2w cores. I'm doing a MONSTER a2w on my FD right now, pictures and how to coming soon so come see it
