Vortech's Aftercooler vs ATI's Intercooler
I am looking at short term runs like the duration of a dragstrip run and not continous running in autocross.
And for what it's worth.. Heatsoaked in 2 hours of stop and go traffic.. My Aftercooler core is merely warm to the touch.

If drag-only, watch the class rules. I just read a power-adder class that does NOT allow intercoolers and does NOT allow cog belts. I think it was at Englishtown.
Personally my experience is only with air-air intercoolers. I've heard air-water are better for chilling. I've also heard of people spraying nitrous across the front of an air-air intercooler to chill it better.
All in all, it would seem that an intercooler that is out front someplace will cool better than a box under the hood and over the engine. It gets hot in there!

Then again, the water reservoir and water to air heat exchanger/radiator for the F-Body aren't over the engine, just the aftercooler. Water to Air exchanger can be located up front too and water reservoir is away from the heat.
Now, if you use lower than ambient temperature water, I guess I can see that it could beat air to air, but how the hell do you get ice water into the system?
So even if air to air might be a bit cooler, it can't conduct/dissipate the heat as well as water.
Weight savings? Air to Water
Reducing tubing/boost loss? Air to Water
Drag Strip? Air to Water w/Ice
ice melts pretty quick in the heat of the engine compartment. there are other pulley setups at limit belt slippage..ATI IMO
I sit about 1" off the ground. Last thing I need are dual intercoolers scraping everything and knocking the air tubes loose.
Andy at A&A and Mike at MMS have come up with good solutions for the C5 ATI kits.
I still prefer the Vortech belt and secondary cog system for the C5. If I had an F-Body I'd go ATI.
