The thought of putting not only one intercooler but two on our cars has always been in the back of my mind. If the orginal is supposed to give you 15% increase in horspower maybe the second would give you 12%. I was thinking you would have it cool the air before it hits the turbo for space reasons, but i don't know if it would do any good. So that's what i was wondering, because this is plenty of parted out TGP's with intercoolers. Let me know what you guy think.
Black...When you compress the air, it heats up but I don't really know how beneificial it would be to put one inline before the turbo. I am by no means a turbo engineer, so I guess I couldn't tell you if it would help... 8)
A few of the turbo dodge guys have dual stock intercoolers.
i don't think so.....there were no dual intercoolers STOCK on any turbo dodge. they were all mounted next to the radiator, alot like the TGP setup. i've never really heard of anyone using dual intercoolers, just bigger intercoolers. maybe if you had a twin turbo?

cooler air is denser so my thought is get it as cool as you can and you can get thast much more air in
yeah but the 1st intercooler probably couldn't really get the air any cooler than ambient air temp. maybe it could i dunno. after the air goes thru the turbo it obivously becomes much hotter. i think a better idea would be a big intercooler & adding alcohol or water injection, or even using dry ice to cool the intake tract. don't laugh i've seen it done. both of these would definately cool the intake charge and the alchohol/water injection would serve to 'steam clean' the combustion chamber too. some people actually use a cold start injector to do this, or even the windshield washer pump. some turbo dodge guys use a cold start injector from a Saab to do this, since their cars (like the TGP) don't use a cold start injector. now as you've probably noticed i have NO TGP :( most of my experience with turbo systems has been with my brothers Shelby. but about everything he has done could be done to a TGP as well. there are actually 10-sec (if not 9) turbo dodge's out there, i would think a 3.1 turbo should be able to reach this too with probably less effort since it's bigger and has 2 more cylinders. 13's should be easy no?

Quote from: 90TGPA few of the turbo dodge guys have dual stock intercoolers.
sorry i misunderstood i think. while no Turbo Dodge's came with factory dual intercoolers, some people do weld 2 stock intercoolers together.

I had an Idea aboutadding water/alcohol injection to my TGP, but I do not know where to put the injector or nozzle. I was thinking UIC Pipe or the throttle body. Either way would be tricky because if you go in too far, it will start to obstruct air flow. I also thought about using a mist system to cool my intercooler....
hmmm, i dunno. i guess i would try to mount in right before the throttle body on the UIC pipe? maybe try to angle it in the direction of airflow like a regular injector does in the intake port. i'd like to hear more about the mist system....
joshua
Well anyways, the mist system is just a fine mist nozzle in front of the IC on a switch. The nozzle is connected to a hose that goes to a Storage container (I.E. extra windshield washer resivor) located in the trunk. And when you flip the swith, it mists water untill you flip it off. I was thinking good for sittin in traffic or just to cool it down. But I dunno, I had plans for it. Let me know what ya'll think.
Here's the link to a owner using dual stock intercoolers.

all i can say is wow!

The dodge setup is cool but i don't think it would be a could idea to cut the air off to the radiator. I was begining to think you could set the second intercooler on top of the other one but then you wouldn't have any air flow to the first one. It would fit and the bends wouldn't be that bad and the air could be intercooled twice but you might have to set up a minature ram air for the intercoolers/mist/fan system. And if you did that you would have to get a cold air intake/ram air system or somehow have your air filtered and directed via to the turbo because you probaly will only have room for pipe their, not an air filter. What do you think?
The pic's are great, and I believe that would be the way to do it, as putting it inline before the turbo will only serve to increase air flow drag, and the inlet to the turbo needs to be as free flow as possible, lest you may dammage the bearings as I understand it. (hence the reason for a KN filter)
By paralleling them in outlet you reduce the air flow through the IC by roughly 1/2, which allows 2X time to cool while in the fins! Therefore, the effect should serve to reduce heat gained by compressor effect significantly, but will need air flow to do it.
This is an interesting Idea, might have some merit if the plumbing could be worked out on our TGP's
sounds good, do you think you could fit them in front of the radiator ( the outside of the car)? It would help airflow. That would be a lot of pipe though. Or where you thinking of parreling the second next to where the first one is? I would love to see it if you got it set up.
I don't think it is feasible to do it the more i think about it if some comes up with great design and trys it i would like to see it, a CAI, and any reduction in heat with the thottle body air pipe would help a lot though
BTY http://www.gnttype.org/techarea/turbo/intercooler.html is a great site to calculate heat loss with intercoolers
I found this site helpful for a lot of homade turbo car mods, including intercoolers, alchol/water injection (which is what the link is for) turbo info, ram and cold air intakes, and exhaust. I might try the homeade setup near the bottom of the page but i am not sure i would get any gain, i am guessing you would have to be chipped for sure, maybe if somebody who knows something about how the chips work, and how this would affect our boost levels could me the link is: http://www.geocities.com/rad87gn/tech/alcohol.html which is worth reading and the homeade kit link is

Hopefully no one will disown me for researching on the turbo buick site. (lol) at least they are not ricers.
just my 2 or 3 cents
how about a supercharger/ blower then inter coolers then turbo to throttle body? sameway as a a/c compressor have a clutch on a blower thats controlled by electric pressure sensor hooker up between the turbo and throttle body. so when the turbo gets to about 9 10 psi the blower kicks on and pushes air through the intercoolers and helps the turbo out.
may work. maybe I'll try it if I get one

Alright, hold everything. Everyone needs to stop fooling around with dual intercoolers and stuffing extra sh@$ in the already packed engine compartment.
What y'all need to do is rip that dang intercooler out of there!
Thats right. Take the ic out and mount it in front of the radiator. Then have custom pipe bent to plumb up to there.
But now what do you do with all that extra space? Hmmmm, How bout a huge K/N cold air intake with a heat shield around it.
