Mines not a square, but my intake is almost the same height as a high ram.
I only have about 3/4"-1"of clearance.

He could measure that pretty easy, I feel like the squares have a lot of hood room.

So many options not enough room.

Guy is finishing the wrap, I wanted the supercharger on but work got in the way and needed to be addressed asap.

I would hook it up direct for now if you want it use it. Won't make as much power and it will need reduced timing but it should still run fine.

Then again I don't like doing things twice either, depends on how soon you want to get the intercooler setup picked out and working.
 
Engine masters did some tests with water to air intercoolers. Even with just the sandwich intercooler plate installed it made more power.
Air to air is lighter, but harder to plumb for the reasons mentioned above.
Water to air cools the charge more efficiently, unless you're doing a really long pull the intake air temperatures will be cooler with a water to air intercooler. If you drag race you can get a big reservoir that you fill with ice to super cool your intake charge.
Water to air is more complicated as you have to add a radiator, pump, hoses and reservoir, but it's how all the OEM manufacturers are getting 1000+ HP out of cars now.
 
We can utilize the timing vs IAT feature in the Holley to reduce timing if IAT temp rises, this would protect the engine in case the intercooler pump quit working.

Here is a short list to ponder, I am sure I missed something making this on the fly.


Air to Water
PROS
- more efficient cooling
- less air charge volume
- better use of space
- potentially lower pressure drop

CONS
- expensive
- adds water plumbing
- more mass

Air to Air
PROS
- simple
- less expensive
- lighter

CONS
- larger longer volume to boost
- may not fit sufficient system
- less efficient
- potentially higher pressure drop

Also I will mention the truck was made to drive down the highway so that has a lot to do with the intercooler.





I know I’m trying to make a race car run down the highway but I don’t care it has to go down the highway.
 
You are talking to a guy that has a solid roller 900HP NA motor running down the highway, and then I add nitrous to that sometimes and end up with 1100 HP on pump gas.

Your setup is pretty mild and not a problem, you just have to decide if it's worth the extra cost to you to go air to water or not.

Here are some options for heat exchangers to work with the water intercoolers, Afco makes some for camaros, CTS-V, mustang, F150, etc. One of them might fit in your grill quite well, and you just plumb two water lines to the intake, and an inline pump. I can get these through my distributor, some of them are in stock.

For example the Camaro unit is a 22.375 x 11.125 x 2.25 dual pass core.

Heat Exchangers

<p>Cooler intake temperatures mean more power. It is just that simple. However, providing your engine with cool air to breathe becomes even more difficult ...

For the pump you can use a mustang or camaro pump, I can get you a mustang pump for ~$180.

Camaro pumps are too expensivbe, so I'd rather have the Mezeire pump for around $280 at that point.

Does anyone but a factory manufacture make a really thin intercooler? I’m not finding much after martlet.
 
One thing you can do with air to water is move most of that to the bed. Pump the cool water up to the front and warm water back to the bed for cooling.

You talking air to air? That's tuff because it has to flow enough air so it needs large piping, 3 - 4" piping. Typically this makes the intercooler thicker as well, it doesn't have to be, but if its not thick it needs to be quite large to maintain flow.

The thermal conductivity of water is 23X that of air near room temp, which means you can use a lot less of it for the same cooling. Now, you have to do it twice, so you lose a little efficiency, but I have still read before that it's 14x more capable of a system than air. This is why the air to water only use heater size hose and can be thinner and still be more effective.

Here's a thought. EVs,and hybrids have electric system cooling systems. The pumps shown look just like ev system pumps. They have thin radiators too. Might find a size that works. More options.
 
Most EVs are running at 400ish volts, pumps, motors etc are much more efficient at higher voltage, I doubt any of that would be 12 volt.
 
Got the radiator, core support out and picked up the supercharger. After this work meeting, I will be putting on the supercharger, new core support, new radiator and fan shroud. Depending on how things shake out I might put the new grill in.
 
Well crap I forgot it needed a different water pump for the supercharger to work and I lost the bolts for the spacer kit to match the ls1 water pump and it needs gaskets.

Amazon will be dropping off a water pump and the spacer kit tomorrow. :surepal:

not sure about that, 400v water pump would cost a crap load just for the electrical insulation. All the cars have step down voltage. The ac pumps are high voltage, iirc it is 3 phase ac voltage from inverter.
