If your turbo is big enough to flow, say, 16psi of air, losing 2-3psi simply means it takes longer to get there. I wouldn't even say more wear & tear.
Understood. Does anyone know have an educated guess on what the post-IC temps would be on these two intercoolers? If there is not a large difference, I would much rather not sacrifice the throttle response. With twin plugs, 93 octane gas, and potentially water injection sometime down the road, I think I should be fine with the higher flowing, less cooling IC - especially since my boost level is not that high.

Any thoughts?

Water/Methanol injection is the controlled squirting of water/methanol into the intake charge. The system involves a reservoir, pump, hoses, and pressure switch. The water/methanol absorbs the heat and effectively lowers the intake temperature. Pat Keefe has had a water injection system installed on his for Turbo SC for a while now without any issues. It's common to leverage the windshield washer fluid reservoir to feed the injection system. A boost activated pressure switch is commonly used to trigger the injector (e.g. you can buy a switch which kicks in at 3 PSI). It's a relatively simply system and quite effective/inexpensive.
