I know very little about intercooling as well, apart from my research here.  However, that intercooler seems excessively large.  It says it is rated for 800 cfm.

If you use the turbo calculator here and type in the specs for the 1.6: http://www.not2fast.com/turbo/glossary/turbo_calc.shtml  You will find that a 1.6 boosting 30 psi at 6000 rpm only uses about 300 cfm.  :shock:


less of a restriction isnt necessarily a bad thing  :)

was I reading it right that that intercooler was only $150 :shock:  I am going to use a saab FMIC on my build. It should fit perfectly as i don't have A/C in my way. But for that price, maybe I will reconsider. The saab has plastic end tanks, and that looks super solid. 8)

I am a complete turbo noob.
I have owned vw diesels all of my life...but never a turbo. I completely understand the consept of cooler air being better, but I have never done anything with a turbo motor. I was just thinking that I don't have working a/c and that should fit up there nicely. It looked like it didn't have much pressure drop and if it is rated for 800 cfm I was wondering what that meant. Did it mean it would cool 800 cfm to outside air temp or if it would cool air up 800 cfm after that it wouldn't benefit? At any rate I figured I would want at least something rated for 600cfm. That is the size carb on my old 400 and that is a na gasser. I just don't know though that is why I was asking.
Also, after looking at the site, is water to air a good idea, or too hard for a daily driver?
whoever it was that posted the link for silicon intakes Thanks. I have been trying to figure out how the heck I am going to piece all this junk I have in the basement into the car...now I know.

air/water is far superior IMO, but more expensive and more complicated.  it would really shine in a daily driver... imagine no heat soak!  air/air intercoolers will start to get too hot while sitting at a light, and so your initial go power is reduced until you get up to speed again.

with the air/water setup you can have a pump set to turn on at a specific temp, and even turn on the rad fan to cool the liquid at a light.  thats where it starts to get a little bit complicated though.

i think the 800 cfm is how much the intercooler is rated to flow.  so if you put more air going in, you'll have a restriction.  sometimes thats good though, so the air has time to cool in the intercooler.

I still haven't  got my block back yet. :evil:
But it is bored and the machinist was impressed that the cylinder specs were to be within .001 when he said most all the other diesels he does are .003. I saw the block laying on the floor and he pointed and asked what is that though? I have searched and have no clue. There is something and it looks like it was threaded or put into the block right under the hole where the vacuum pump mounts. It is on the transmission side and he didn't notice it until it was cleaned. It looks only to be about an 1/8" hole. The question is what is it, how do I fix it, what is its use, and what information could you guys give me on it?
any ideas? I am fresh out.

Very nice!  I'm glad to see the flow bench numbers.  What was the cost?

My cost was maybe different than yours since he likes me LOL...Actually he gave me an approximate cost and said it could change with the price of metals, valves, phase of moon etc, but his quote was approx.530.00 and with shipping both ways I had about 600 in it total. That was cleaning, parts, labor, porting, getting the broken stud out, and cam seal...everything. So it was close but I will let him decide what he charges you. His name is John and will quote you whatever you need I am sure.

PS, one hell of a guy to deal with, great communication, and easy to talk to. He is not a my stuff don't stink pay tons of money now blah blah blah kind of guy. I would recommend 100 percent. Also, if he comes up with a camshaft soon I will be "testing" that as well ...if the wife doesn't care (find out :lol: ).

Well, for $150 it certainly adds to the TOO COOL factor even if is it almost 3x larger than required. But hey, what's the harm ? The temp drop should be a little more - a good thing - and the increased spool time sounds like its not an issue for TheMan53 :-)  I like this idea - but I'm not looking to race, but have power w/o cooking my engine.

Well I got it back and here is the pic of the "thing". It looks more like a pop rivot without the center part, but it doesn't get through the block so I think I am just going to run it. Let me know what that is please. I really don't think it is anything, but if it is clue me in.
