I would like to get a 4 core i/c for my tgp, does anyone have any suggestions as to where I can find one?
You could try Spearco. I'm not sure if they have a website or not.
here ya go! http://www.turboneticsinc.com/spearco/
might wanna take a look at this one for the product listings http://www.hardracing.com/CARPARTS/Misc/SpearcoInt.htm
I have it on my list to check this idea out but anyone is welcome to give it a look see, or try it out before me!!
Spearco does make some excellent cores and end tanks, their intercooler book is also very good info, and there is not any bias I could see there towards only their side of the story.
Aside for a front mount, the other idea I was looking at was to upgrade the intercooler in the same place as stock with a thicker unit (with the same condenser fins removed idea). The one I found at Spearco was part number 2-210 (a lousy $240 retail for just the core), and is damn near exact in height and width to work in this location. The key value is this core is twice as thick, and good for up to 670 cfm/450 hp. That is just too good, pressure drop with a 300 hp turbo is only .5 psi, good there!! Efficiency is 80+% at only 15 mph of wind, again damn good!! Now the only trick is getting some custom end tanks made up, and checking the area for clearance of all this, and my first brief check reveled the 6 inch thick core would fit, but the end tanks might necessitate pushing some AC hoses over an inch or so (not a big thing for the AC lines to accept). Not sure if anyone has access to aluminum casting shop, I have found one that will even do a run of 1, so when I get a chance to check this out, will be able to get things made up, less someone beats me to it, so beat me, I am too busy with many great projects like this one to get them all done in time for all your power hungry wolfs :shocked!: If I end up getting to it, I have dual temp/data-logging equipment to run tests before the upgrade and after, and dual pressure tests as well, and will document all this so there is a track record to prove out its value as a viable upgrade.
On my over mod?d black TGP, I will put in a big front mount (the upgraded stock/double thick unit will be testing on my TSTE). If everyone does not already know, those long ass ones all the ricers got are NOT the way to go!!! Those long ones have too much pressure drop, unless they are really tall and have a lot of tubes! There is the Efficiency value too aside from Pressure drop that must be evaluated, and the actual Turbonetic Spearco catalog section has this info on all their intercoolers, along with max CFM, HP, etc, its good info to have, it made me pass on what ?looked? like a nice huge intercooler on eBay. The one on eBay had the preferred big number of tubes that did not run a long distance, but when I checked that core out in my Turbonetics/Spearco catalog, found it had a pretty weak efficiency rating, even though the pressure drop was good, damn only $450 buy-it-now too :( . The core I want is the 2-179, with a 350 hp turbo the intercooler only has nice low .5 psi pressure drop, but an even more stellar 98% efficiency at only 20 mph! I have seen this intercooler on a lot of Grand Nationals/Turbo Regals, they did some reading too!! Trick is the core alone is about 20? square, so fitment will be a trick, but once I can actually get to my TGP (after a 4 year wait) I will pull the front bumper fascia and see what kind of room there is to work with, and how extensive any mods end up being, and as always, will document all my findings, and will have digital camera by then for all this to be worth checking out on my web site.
Blah, blah, bye!

I don't understand why the long ones wouldn't work as well as other designs.
I can get a 30"x(upto 18")x2" intercooler locally. I was thinking of getting this. But then I saw your post on long intercoolers and was wondering why the long ones wouldn't work.
Hey Jeff,
When you get that digital camera, be sure to get some photos of your STE :D

If the air travels along the longest portion of the intercooler, it will have more resistance and slow down. As it slows down, it loses pressure (I could go into the theory but trust this one). The more it slows down, the more the pressure drop.
However, the more surface area the air has to expel its heat, the denser the charge can become. So a larger intercooler for somewhat obvious reasons works better. For the same surface area and cooling capacity, air flowing along the short path of the intercooler will have the least pressure drop, than if it flowed the long direction.
