Has anyone ever had a custom water to air intercooler made for their truck, or know anyone that's tried? Something like the new 4.0 TRD intercooled system or what you see on Stillen's 350Z Intercooled Roots kits that bolt between the charger and intake manifold?

It would probably require hood modifications to deal with the increased height, but something like this seems like it would make a lot of sense with a low failure rate and be fairly straight forward to install. Bolt it on and plumb in coolant inlet/outlet. Longer belt.

I know the URD and TRD 7th injector kits see a minor cooling effect, and URD offers H2O/Meth kits.

Thoughts and/or experience?

it works but the manifold has to be designed for it. i worked for stillen and vf eng. and these kits were designed for use with a air to water intercooler and you just take them out if its not wanted(dont know why). the air to water is the way to go for efficiency and i wouldent even mess with water/alcohol injection.

the cost is much higher to go this route and more parts( water/air cooler, radiator, elec water pump, tank.

as with anything it can be done, i used to head up r&d at vf so if you haveany more q's let me know and i dont recall how th charger setup is on the older tacos but i may be able to make something work for you.

ive thought about trying to cool the air charge before the s/c as it wouldnt need as many mods to pull off.

the gains wouldnt be as dramatic but im sure it couldnt hurt...

you can get small intercoolers that came stock on old turbo volvos for next to nothing, know alot of vw guys that use them. not the best or pretty but might be good for experimenting without wasting $
i know this isnt customtacos but thats my :2cents:

I tried it years ago on a Gen 1 s/c.

It was a fun little project.

Looks like you learned a lot. You could have used Evans waterless coolant to get rid of the water corrosion problem.

All in all, I'd say you might as well go to a turbo if you want intercooled boost. I find the Aquamist wi works ok too. I don't hear any ping (up to 10.5 lbs of boost).

True, it seems more intricate than H2O/Meth injection, but no refills. Pretty much forget about it, other than to change the coolant occasionally.

I'll definitely keep you in mind. If I decide to go this route, I'll be doing it this fall, once I get my tranny VB upgraded. I don't have any welding/fabrication abilities at home, or the skill/experience, for that matter. Seems like there's plenty of room for a heat exchanger between the grill and radiator, even with my tranny cooler. Looks fairly straightforward to bolt something between the charger and intake, as well.

I've found several posts on a couple of forums about people trying to rig their AC up, but they never posted back with any results and one of them gave up.

Wow, crazy project. I'm impressed. Looks similar to these:

I was thinking more along the lines of something that bolts between the intake and supercharger, though.

Too bad someone from the aftermarket world hadn't jumped on this back when they first released the 3.4 supercharger. Seems like all of the roots kits are coming out with air to water intercoolers now. Maybe the technology has just recently arrived at a reasonable cost.

The custom fab and non-smogability here in CA kind of rules out the turbo option for me. With the TRD being smog legal, all I'd have to do is remove the intercooler every 2 years to smog it, rather than everything involved with the turbo.

I picked up a SC cheap off of Craigslist and had it rebuilt by Magnuson, so I'm already headed down that road. I really like the power/torque curve of roots supercharged motors, not to mention the simplicity/reliability of the overall package, when tuned right. I'm not crazy about the heat issues with turbos, either.

I've owned both a supercharged (Camden) and a turboed 22re truck. While I really enjoyed the top-end pull of the turbo on the street, the supercharger fit my daily driving and off-roading preferences better.

Not sure about all of the Volvos, but I believe they were air to air set-ups and wouldn't offer much benefit inline before the air is compressed.

its not worth the money to try to cool the air before the s/c .with the heat of compression theres not too much cooler inlet air temps will do .

from the looks of it it very possible to move the charger up and bolt in a cooler core.

my buddy has a water/alchol inj system in his ford prerunner and has nothing but problems when the resi level gets low in the rough stuff. no matter how you put it for offroad its unreliable

That was one of the main things that lead me to look at an intercooler/aftercooler. I don't want something that's going to run dry on me when I get on it offroad. It has a place street/strip, just not off road, IMHO. I'm sure there's those who've had no problems off road.

I'll probably just run the URD 7th with their 2.2 pulley while I sort it out. I trust Gadget on reputation alone and if he says it's a safe combo for daily driving, I believe him.

Besides the power increase, I'd like to intercool it to decrease heat stress on the motor for longevity's sake.

What kind of off-roading are you guys doing? I very rarely get into boost off-road. I guess the desert racers might need to carry an extra jug of water/meth.

Yeah, the whoops at speed make sure nothing stays where it's supposed to be.

The TRD Supercharger for the 5vz is a nice unit. It is proven very reliable and it makes decent power. They fell just a little short on engine management and fuel delivery, but URD can help you there.

Several people over time have tried to rig up a charge air cooler with the TRD Supercharger and non have proven to be worth the trouble or cost.

If you really want a charge air cooler it would be simpler to start from scratch instead of attempting to modify the TRD unit.

Here is a picture of a supercharger system in its early prototype stage. It runs well and I hope to have some better prictures of things when I get parts back from the powder coater.

Gadget is this a kit URD is putting together for future sale(please oh please:rolleyes: ) or is this you just having fun? More importantly what are your projected numbers for this system? Your knowledge and imput are always valued on these forums, thanks for taking the time to mingle with us less informed folks:)

outer cooler

I was playing with a couple of ideas with a buddy of mine who owns a Neon SRT and the idea of thermo wrapping the outside of the supercharger and hooking up a co2 to spray under the wrap. As far as how to manage the bursts of co2 or how much cooling the outside of the charger would do, I dont know. Just an Idea. It would probrably look ugly as shit as well.
