3SGTE: eBay IC cores: for low power only

[mr2ya]

a core should be a core
IF sizes are the same
fans are same
and most important same turbo
of coarse there is
tube and fin and
bar and plate
im sure there are slightly better ones
but for the most part the same

[spins]

Okay, which is better, trunk mount or top mount? And what is better for the price, i have no plans to do A2W

[spins]

Oh yeah what the best IC's available for top mount and does anyone have any pics of a top mount conversion?

If I were building a custom IC setup, putting an A2A core in the engine bay is the last thing I would do (which means no to a top mount) IMO. If you want to stay A2A, then go trunk mount.

Thanks for the research, but this post generated a few questions for me:

1) Were the cars using the same turbo at same boost levels? I ask because different compressors are more / less efficient at different boost levels which should lead to increased heat even at similar power levels. This test should be done on the same exact car to really backup the claims.

2) Why would someone use a small intercooler like these SMIC's to support 350 whp in the first place!!?? That, to me, is a no-brainer.

3) I will try to help add my information as soon as I finish my turbo install. I have a spare temp gauge and I actually road race my car and could get some logs of the temps as I run. I will have the BERK shroud and fan on it, but it is an EBAY intercooler kit. My turbo is a small 16g.

Thanks.

i saw pics of one trunk mounted intercooler and it appeared to take up the entire trunk, is this a typical installation

Every TMIC is a custom install. Most of them take up the entire FLOOR of the trunk. I've seen people install mesh grating over the core, so they can still put packages in the trunk.

Because they only use 350hp once or twice a day IF that often. The rest of the time they are staring at the brake lights of the car in front of them....

i got a question. I have a A2W intercooler but no heat exchanger. I have the pump connected to a switch so i can turn it on and off as i like. Do you guys recommend keeping the pump on constantly when driving around town or cutting it on only when running hard. Also where can i get a good heat exchanger and what brand should i look for. And does the heat exchanger benefit alot. Sorry to jack the thread.

[Sang]

An A2W with no HE means that the water will continually increase in temperature. The idea is to keep flowing cooler water through the core, not hotter.

I'd rather have a dinky greddy SMIC than a A2W with no HE, IMO.

I'd leave it on constantly.

Sang is right, get a heat exchanger!

Visit your local junk yard. You just need a small radiator. You can probably pull one from a VW or Honda that was wrecked from the rear.

I would never hack my trunk up to put a damn intercooler in it. I would go A2W intercooler. Here is a hole setup for 500$ eBay Motors: TOYOTA 3TC 1.8 WATER TO AIR INTERCOOLER KIT UNIVERSAL (item 300208730625 end time Mar-26-08 11:41:52 PDT)
You can all so find head exchangers on ebay for like 120$ or so

No, they were not done with the same turbo but they were done at the same boost levels. If you actually calculate the differences in adiabatic efficiencies in the maps of most modern compressors, you will get no more than a couple of degrees C of temperature difference in the compressor outlets across the entire compressor map at any line drawn across a given pressure ratio. That means that outlet temperatures are dictated almost excusively by pressure ratio. Both cases were taken at sea level at the same boost level, hence the same pressure ratio.

Obviously, my observations are not perfectly scientific and have some degree of error, but the results are many orders of magnitude greater than the error factors and a more scientific test will end up reaching the same conclusion.

so you have a W2A IC with no heat exchanger and a pump, where does the water go when pumped out of the IC?

Ask Justin311 how much his A2W IC costs him as a weight penalty

So far, the most efficient intercooling system we've seen in terms of packaging, cost, convenience, and trunk space, is a meth injection kit!

With the nozzle placed right after (or in) the coldside endtank of a cheap SSAC intercooler, SpeedOracle datalogged temps never reaching over 106 degrees, even after repeated dyno runs with a crappy fan. (ask Ken how high the temps got with his Spearco sidemount..heheh)

Chemical intercoolers don't care how big your core is

i have a ebay side mount, im not going high HP but i'd like to crank the boost on my trimmed ct-26, so i was thinking of making my own meth kit that would kick in around 9-10psi to help with the cooling affect. How much am i looking at price wise, and how hard is it to setup one of these kits?

[boostd4]

No need. Someone already did this test on the other board with a JDM CT26 and couldn't make more than 250whp even with the meth. The turbo is just out of steam over 15-16psi. It didn't make any more power with the boost cranked up.

At that level, the Ebay IC should be just fine by itself

well, hopefully i'll show the "other board" just how i roll, and make more than 250RWHP with my setup.

[mr2ya]

yeah air to air in a engine bay has never worked


wait porsche's dont have choice
I guess i blew that thought out of the water

900whp and more
are out there..

[kercha83]

the pump is in the water resevoir tank and pumps water into the intercooler and back into the resevoir.
