It's a part they developed for their HUGE boost 951s.

Looks cool (no Pun intended)

it's basically a mini-air/water IC
it's really cool

seems like a novel idea, but where are the numbers to support how much it decreases the air tem?

doesn't seem like it would cool the temp MORE than a regular IC, but it may be able to keep it more consistent over long pulls/time if you're tracking the car... (kinda like a air to water like chapel said).

Interesting, but for $600+ dollars, I wouldn't want to be the crash test dummy. I'm sure you could do a air to water intercooler for about the same price and those are proven.

well, they're proven on the 944 Turbos (951)
They run 2 in parallel on one of their big turbo 951s
They've been around for a few years.
Might be interesting to be put in with an existing TMIC or FMIC

here's the setup they run on one of their units.
one before the factory IC and one after.

here's another where they've replaced the AirAir IC entirely
does seem a bit overpriced, but it's aimed at Porsche owners...

I think im gonna try it out on my evo or subaru just for test purposes.

Right on man:)

Whats the inside look like? Where does the water supply come from and how does the water supply stay cooled?

coolant comes from your radiator
you can put in a radiator FOR the THP to cool it even more.

coolant passes through the outer channels, cooling the fins inside

Here's the standard setup:

just a coolant line and a pump.

Here's one with a coolant radiator for JUST the THP
little one.

I wouldn't want to use the engine radiator coolant - Seems a better idea to use separate radiator core

you could do that too.

Compare this to the pwr barrell IC?

not familiar with it?
link?

this I imagine (http://www.pwr-performance.com/intercooler.htm)

Well, it's expensive.
Not enough information for me to really comment on it in all honesty.

For all I know, it could work magically well, but it sure looks like an air/water IC to me... made for tight spaces... for rear-engine cars... who have no good way to get air from the front of the car, etc...

Like, say, Porsches.

Very very very likely to be pointless on our cars.

actually, it was designed for 951s... front engine Porsches

Interesting.

those two installed photos are from 951s.
and from what I know about the red one, it's pushing 25+psi...

i would go for a co2 spraying sleve, dei makes one that freezes the inter cooler piping, seems like you would get more of a gain that running your intake charge through hot raidator fluid.....

Well, 25psi doesn't mean anything really without a compressor map to look at and a bunch of other details.

Nothing speaks to me other than hard numbers.

- Pressure drop at various CFM ratings
- Inlet vs. outlet temps at various CFM ratings after the unit has had several WOT pulls performed

If they can show me at least a 60% efficiency (repeated without cooldowns, like road racing), I'll perk up ;)

Looks to be a nicely packaged system but a separate cooler is needed. What is your coldest coolant temps? 180..even 170?...now how bout on a track???

Air heats up around 11 degrees per pound of pressure, this is what I've always been told, with a turbo/blower that is efficient. At 20lbs of boost, the air is roughly 220degrees + ambient. If that passes through your 170degree-cooled tube, regardless of efficiency, it's still too hot for meaningful power and will never go below 170degrees. It's my understanding that the STI pulls timing when IATs are over 140. This is why using your radiator for fluid is not a good idea.

I have a Magnacharger on my Z06. It has a separate radiator in front of my coolant radiator. This feeds the heat-exchanger under the blower, that sits right above my intake runners. After running a 20 minute session at Limerock, I opened the collector tank and stuck my finger in the intercooler fluid...COLD. This was a relief, the sytem was doing it's job. My engine coolant, OTOH, was 220degrees...not a good idea to cool the intake air with that fluid.

Depending on the airflow that could be utilized for a cooler, and the efficiency of the tube, it could be a pretty good option as it appears to be able to flow quite well. I figure a water/meth system used just after the tube could work well enough to bring IATs pretty close to ambient or under.

I don't like how there is an open area in the center of the tube, though.

Probably a good option for someone with very little space, better than running nothing, but I'd need to see some numbers/testing to be a believer.

For a drag application, CO2 being blown through the tube's cooling passages could be effective...

Be good,

I'm using a 13" hard pipe in a Miata. (supercharged). I brought this back to the UK after living in the US from 1994-1998.

It has reduced intake temps from +45'c to +20'C. I have some improvements to make and should get this to +10'C. (hard pipe is touching rad pipes at the moment, I'm using wrong sized piping until my new parts arrive and I have an idea for getting the efficiency up by ~10% by turning the hard pipe into a part of an expansion manifold used on some of the latest Porsche Turbos.)

I wrote a much longer post but it got wiped for some reason. If anybody wants more details on the installation, let me know and I'll give you the full story.

P.S. I drove a Subura last week for the first time. Impressed with the torque and handling but I think my friends car needs some work, the top end power wasn't there and his brakes were shot.

I used Lindsey Racing stuff about 7-8 years
ago on my first car..'88 951 (i miss that car)

1- high quality stuff
2- it dose help to lower temps/ they come in different lengths.
3- was thinking of adding one to the WRX
