a custom IC
 
i searched about this and didnt come up with too much
so heres the deal
i am a student so i am constantly short on cash and i want and intercooler
i dont have a grand to drop on an intercooler but i want one like people in hell want icewater...
is there any intercooler that can be ripped from any car in the junkyard or any way to make one that is budget and fab feasible?
whos tried?
what were the problems?
i dont need anythign fantastic
good will serve fine
thx
barban

The only way that would be cheaper than getting a used upgraded IC from some one would be if you have the skills and tools to fab up your own piping, ducting, and mounting.

There's no free lunch...

Narfle 08-09-03 01:52 PM

welding is a cake walk
mounting should be easy and i think if i go Vmount ducting would be easy too

hmmm one of the older porche cars had a nice intercooler if i remember correctly.... do a search cause there have been threads on it

isuzu NPR
do a search on it.... if you want one, let me know at rxrotary2_7@yahoo.com

porsche 944 turbo's have a very large ic. i think it's about 4" thick and looks like it can flow some serious air.

Narfle 08-10-03 01:39 AM

5" actually
im lookign at a vmount 944 ic
ill let keep you guys utd

what about taking out the battery and running two Stock ics..from the turbo, in one, into the other, out the 2nd one into the engine? All it would take would be a few custom pipes and mounting brackets.

teamstealth 08-10-03 02:28 AM

my bad...relocating the battery...lol

That's a very BAD idea. The stock IC has a pretty large pressure drop as is. Running it in series would at least double that.....

Barban: Having skill with a welder is only part of the problem. You will now have to fabricate a duct or modify someone else's to route air to the IC. Not to mention trying to fabricate a bracket or some type of mounting system for the IC. It's all do-able I'm sure, just trying to make sure you understand all the work involved.

teamstealth 08-10-03 09:15 AM

would it really be that much worse off than a huge FMIC as far as pressure drop goes? I had no idea it was THAT much of a crappy IC. Just figured id ask since ive got my stocker installed and a friends sittin here i coulda used for free :)

thats why im going v-mount
it will make the ductin a lot easier and brackets are home depot nonsense

teamstealth 08-10-03 04:49 PM

yeah im planning on going v-mount as well...but i figured if i could have a temp larger SMIC for $100 why not? Ive got a custom shop owned by a friend that could fabricate stuff for cheap.

Good idea, if you run them in parallel instead of in series (two y-pipes). Sounds like it'd be a good experiment and it certainly won't cost much...

teamstealth 08-10-03 06:55 PM

parallel would be quite interesting...not to mention new custom turbo piping comingt from each individual turbo. sometime soon were gonna cook up some more ideas and actual plans.

teamstealth 08-11-03 01:20 AM

what would be the benefit of running them in parallel...not to mention how would i merge them back into one pipe?

Here's the way I understand it:

Running them in series doubles the pressure loss. If the stock IC has a pressure loss of 1.5 psi, for example, running two in series would result in a pressure loss of 3 psi. Put another way, the same volume of air is restricted twice in a row.

The pressure loss of running the ICs in parallel should decrease, since you are effectively increasing the internal volume of the IC. Using the example above, the same volume of air has more paths to take (less restriction).

To hook it up, the output of the turbo Y-pipe would split out to the inlets of both ICs and both outlets would connect to the throttle body. These pipes would have to be equal in length, that's why I mentioned using two y-pipes.


teamstealth 08-11-03 12:54 PM

yeah i get what ur saying now. Why equal in length tho? so the boost still builds smoothly since im NS?
