People should read maximum boost by corky bell.
And to add to the where to measure PSI debate above...... depending on where psi is measured, it might not be accurate to compare two systems. 7 psi in one system and 7 psi in another system might not have the same psi charge entering the engine. There can be some losses going through intercoolers.
Im curious to know more about Stillen's air to water intercooler built into the manifold. My first original thought was there doesnt seem to be that much area inside the manifold, so to get sufficient cooling this system might be more of a restriction than the front mounted intercooler in the GTM system...... although water to air has about 4 times the cooling capacity of air to air.
I havent seen a flowchart or diagrams or any good descriptions or pictures of the inside of Stillen's air to water intercooler. Does anyone have them or is this a proprietary design by Stillen and are they keeping them under wraps?

Vortech kits often use a air-to-water IC on other cars... but most people running much more than the kit's stock power usually swap out to a air-to-air IC. See their Mustang or S2000 kits for example.
The design remains yet to be proven... only time will tell.

It's perfect for most daily drivers, unless you're doing extended WOT pulls to very illegal speeds. Air-to-water is more compact and more efficient, but there is a limit to the speed at which it can pull heat out of the charge before it gets overwhelmed (just how a air-to-air IC that is too small will get overwhelmed).

I used just distilled water when I had my vortech on the s2k, but if there's a way to improve the system, I'm all for it.

I'm not that familiar with ethylene glycol, but isn't that antifreeze? It has a higher boiling point than water, but I believe the thermal capacity is lower than water...

I dont know if it is feasible or cost effective at this point. In the beginning, I just plan on using the stock Stillen setup and going from there.
