Keep in mind that that IC was built to cool ~200hp worth of airflow....a lot more than most ppl will be flowing through a vw diesel.

as long as the intercooler gets good airflow, even a small one is better than nothing :wink:

Heres one that lowered performance because its too small:http://vwdiesel.net/phpBB/viewtopic.php?t=12278&postdays=0&postorder=asc&start=15Specifying an intercooler by HP is bogus. Pressure drop vrs boost is probably better. CFM is probably best.Anyone know what CFM our various turbo put out?

Pressure drop vrs boost is probably better. CFM is probably best.Anyone know what CFM our various turbo put out?well if i read that thread correctly, 1~4psi@35psi is a bad thing? who actually runs their turbo at 35 psi daily? and would you not expect that kind of pressure drop relative to the amount of heat that you remove? :lol: looking at: 0.2~0.5psi@15psi - it seems to be a good intercooler to me. granted if the intercooler manged to drop 1~4psi@15psi then yes, it would be near useless, but if the temperature drop is high, it will reduce egt's with less black smoke. so i'll stand by my statement that it is still better than not having an intercooler :wink:i think zukgod's problem might have been with a boost leak with the intercooler plumbing, or possibly with the way it was setup. running at those pressures anything is possible. plus the k24 is only efficient to around 20-22 psi, and the T3 possibly a little more, but not much. after that the exhaust backpressure exceeds the intake pressure.

His EGT went up, smoke went up, and I suspect his power went down. At 25 PSI this intercooler is worse than no intercooler. :wink: I don't know if you can safely get 100 HP out of a 1.6td at 15 PSI.No leaks in my system at all, double checked everything. I do think I have to many 90 deg bends though and I will be taking as many of those out as I can here shortly. I'll come out of the turbo with a 45 and have it angled toward the pass headlight rather than a 90 out of the turbo then snaked around everything to get where it needs to go.saurkraut,you are correct, my power was different after the IC install but only at the mid range area (more), after that it kinda dropped off. Before the IC if I really pushed it in third I could touch 40psi thus the IC quest. I know the K24 is way past it's range there so my attempt was to help drop the intake temps with the IC. Right now my clutch slips so damn bad I cant even get on the freeway fast so till that's taken care of I cant do any further testing.I found a much larger IC last night. 31" x 12" x 3" with 3" inlet/outlets.I figure it flows more than double the current one. I'll be getting that installed next week sometime and if all goes as planned I'll get a new clutch this weekend. At that time I'll be able to report back the improvement if any.No I don't run it @ 35+ psi all day but when I do I want and expect it to function as intended so I'll keep changing stuff till I get it where it needs to be, with all your guidance that is :wink:

As you can see, the 1.6TD moves far less air (CFM) than the SR20 but they move a similar mass of air given the difference in PR (This also demonstrates how both motors should make similar torque figures dispite the difference in HP). The temp of the air will be much higher with the 1.6TD due to the PR so I will concede that it is likely that I am putting more heat into my IC than in the stock application, but the pressure drop should be less. That being said, this IC is better than a lot of small IC's from a heat rejection standpoint as it has large cast aluminum endtanks and inlet/outlet to transfer heat to....better than plastic no doubt.Phew!
