I'm not concerned about 200 degree air for daily driving. Many OEM vehicles use jacket water for intercooling because it works. The second intercooler will easily shed heat from the low volume 200 degree air under daily driving conditions. If it turns out to be an issue, it would be simple to add a 3 way valve before the core to divert the coolant around it.

Also I need to verify is fluid is transferred through the heater core if the heater is off. If it isn't all I'll have to do is turn the heater on before a run to engage the 1st intercooler.


I'm looking for input on the heater core outputs on the water pump, and suggestions where to tap the coolant system for intake and return.


Thanks all for the input.

 

2 intercoolers will give you 2 pressure drops.
How is your air over 300f.
Is that pre intercooler.

Air/water Ic work
WHEN
Sized properly inter cooler, large hx, good pump.

If you want to route your water through your heater core,
Turn temp **** to hot, but ac to max cold.

 

Yes pre intercooler. I am adding 200+ degrees to ambient air (when the supercharger is at full tilt).

Thanks for the info on the heater controls!

 

I've been drinking so maybe I am on crack, but why not just get a bigger intercooler and not over complicate things. Also, is your current heat exchanger big enough? Have you measured water temps?

 

I agree. This is one of those situations where you're putting duct tape over duct tape to hold **** together.

 

This thread sounds really familiar...

Read that. Guy wanting to do the same thing. Use the spreadsheet I made. Its not a worthwhile idea. You are better off fixing your current intercooler situation.

 

I agree with the majority of responses on this. It seems you are making a simple heat transfer system way more complicated than it needs to be. A properly sized and setup A2W system should be able to keep IAT within 20 degres of ambient. From the numbers in the first post, you have a good start with only a 56 degree rise in 100 degree ambient temps. Unless you are also logging compressor inlet temps, your charge temp rise may not be that much. I would look at matching pump flow and heat exchanger size or adding volume before trying to add engine coolant into the system.

 

With a centrifugal supercharger, I don't know why you would be a/w intercooling anyway, unless its a mostly track setup and you want to add ice to the water to rapid cool it between rounds and what not. But a/a have shown over and over to me more efficient on the 90% street application. Just my 2c

 

Like others have said, this sounds like something that is being completely over thought here... Without doing the obvious upgrades like a bigger IC, HE, larger pump, larger capacity tank, check out a product that was called a Killer Chiller. It was a fluid to fluid intercooler setup that worked pretty well back in my Lightning days.

 

My current a2w set up works fairly well. The point is the lower the air temperature entering it. The core running off off the jacket water is going to tend to stay near 200 degrees. There is plenty of cooling capacity it the trucks cooling system. This heat engery will stay out of the second IC thus making the second IC more effective. Shaving 90 degrees off of the air entering your IC is going to translate to more HP.

To get the same performance out of a single cooler you'd need a much larger heat exchanger, or you have to cool the liquid below ambient with ice or the AC system.
