With all the talk concerning turbo's lately, i though about selling my s/c and getting the ems system(which is good). I don't want to go to the hastle of uninstalling the s/c and installing the turbo plus the added expense. I searched the forum and saw alot of folks talking about a a/w intercooler for the s/c but has anyone worked out the details. I thought i might go that route and use the smaller pulley. this should meet my needs very well.

thanks,
 
Blarsen has had his air to air onboard for years as well as a couple others....
Nick was working on a second batch of IC's for a group by... thinking they were air to air setups and 750-900 IIRC
Then a few folks have air to water
DJ is one....
FirstToy/Inverness did theirs together a year or so ago with a great writeup....

Landtank was also working on development of one... may want to follow up on that one and see where it is in production.

then from time to time you will see a non TRD branded IC that was a prototype that should have gone with the SC kit. I believe it was air to air as well.

The intercooler still works great! replaced the small hood scoop with a larger carbon one..

It is just my opinion and we all know what those are worth, that if you are going to spend any amount of time crawling slowly offroad that having an A2A intercooler mounted on top of your engine is a bad idea. It will work on the highway at speeds, with a decent scoop, but offroad all that heat from the exhaust manifold and engine is going to rise and heat soak it very quickly. If you are talking about a front mount intercooler that is outside the engine bay I think that is quite a bit better, but I couldn't figure out how to fit one without having tubing hanging under the frame so for me it was A2W.

My .02. Without an intercooler the heat from the manifold and engine rises up and will be at temperature X regardless. An air to water still needs airflow over it somewhere so they both end up in a very similar situation at slow crawl speeds. Very little to no difference.
 
Yes an air to water heat exchanger does need air to move over it, that is why it sits outside the engine bay, and has its own dedicated fan as well as the engine fan drawing ambient air over it. I have seen engine bay temps +70 degrees over ambient on a moderate day.
 
What is so difficult about an air to water intercooler, that one hasn't been developed for the TRD setup by now? Seems like there would be a pretty big market for a bolt-on intercooler with the SC guys. With the SC heat issues I can't imagine not wanting to have one if it were available.
 
If an SC guy won't offer up, one the NA guys should jump on this. If I was down there I would be willing to buy an SC especially if there was someone willing to fit up and install an intercooler for free. With an intercooler and small pulley, what are you looking at.. 100hp gain? About $32 a horse.
 
All very good points. I'll still contend in a slow off road crawl they will both become heat soaked and be the same amount of worthless.

After 2nite my charger will be on! Maybe I'll take them up on it. See what they can conjure up. I'll even drive all the way out there :)

It isn't difficult and EMS Powered wanted to make a bolt-on kit and asked for anyone in Texas to give up their TRD truck, and they would get a free system. As of yet no one has taken them up on it.

All good points... neither will work very well if you are going slowly on a trail. But the air to air if far more efficient on the road.. here is a quote from someone with more expertise than me..

"There is an overwhelming quantity of ambient air available to cool an air-to-air core relative to the charge air thru the inside of the intercooler (The iced down water intercooler is the only exception to this argument.). At just 60 mph, with a 300 bhp engine at full tilt, the ambient air available to cool the intercooler is about ten times the amount of charge air needed to make the 300 hp. Whereas the water intercooler largely stores the heat in the water until off throttle allows a reverse exchange. Some heat is expelled from a front water cooler, but the temperature difference between the water and ambient air is not large enough to drive out much heat. Another way to view the situation is that ultimately the heat removed from the air charge must go into the atmosphere regardless of whether it's from an air intercooler or a water based intercooler. The problem with the water intercooler is that the heat has more barriers to cross to reach the atmosphere than the air intercooler. Like it or not, each barrier represents a resistance to the transfer of heat. The net result; more barriers, less heat transfer" this quote is from Bell Intercoolers.. http://www.bellintercoolers.com/
