More water/air intercooler pics.

[TCD]

I didn't have a chance to respond to a few posts because the thread got locked yesterday. I am going to ignore any negative posts and would appreciate that others do also so the thread stays open.

Here are some pictures of the water/air intercooler components. We chose a water/air intercooler for two basic reasons.

1. It's has superior efficiency vs. an air/air unit. Water can absord heat at a rate of 13x that of air. You can therefore use a much smaller core. The water flows through the small surface area of the core and the charged air flows over the large surface of the core. The core for the 535i is 3x4.5x18. The charged air has 81 square inches of surface area to flow through. Imagine trying to fit an air/air intercooler someplace with end tanks that have 81sqin.

2. Packaging.

An air/water system is very simple. There are four components.

1. Intercooler
2. Reservoir
3. Pump
4. Heat Exchanger

The pump runs the entire time the engine runs. It circulates the water through the intercooler where it absorbs heat from the charged air to the reservoir and then to the heat exchanger. The heat exchanger acts like a radiator.

In a street application the same water will never see the intercooler twice. The intercooler has the same efficiency regardless of the vehicle speed.

In a road race application an air/air intercooler is preffered because it offer a cooling medium at a constant temperature and a vehicle speed that is fairly high.

Thanks,

thats cool bud. very neat, compact and efficient.

I guess the distance air has to flow is less, which can onlt be good for throttle/turbo respone.

Well in this case the piping length is about 14" vs 6 feet if the intercooler was out front.

i'd say that was less distance

how fast does the air travel in the intake?

Is this for the e30 or the e28. I know it said in the other thread, but I cant recall

This is for the 535i but the 325i will also have a water intercooler. We should have it built within 3 weeks.

Todd

[Jb325is]

I'll take one of each!

I wish, can't wait to see pics of the finished product. My dad saw your e28 at Fiverfest and said it was incredible. Arent you already making ~315 at the wheels non-intercooled on the e28?

It made 311/375 rwhp/rwtq at 15psi non intercooled. I expect another 30-40rwhp with the intercooler at the same boost level. I just installed a T61 on the 535i last weekend in preparation for 20+psi.

Will you be attending Sharkfest in AL. I am bringing the 5er down.

Im thinking about it if we can get some kind of valence for the euro bumpers. Im not taking it anywhere how it looks now. You know of anybody with a valence for sale?

Just thought you might want to correct, "absord" and the fact that water can't absorb heat better than water.
Call me a dork, but it makes a difference when corrected. 8)

that IC is actually be used in the m20 todd or if for another application? where will be mounted in the m20?

[Jb325is]

That intercooler is going to used on an m30 (e28 535i), but he's using a similar design for the e30

[STS]

The E30 IC will be an air/water as this one is, but the design needs to be very different for packaging reasons.... they'll do the same thing, just look different.

so you are the partner of TDC? Todd..?

Yes, Todd and I are partners in this little venture. The Twin Turbo 635 on the TCD website is my little creation.
