Is there any difference in engine durability between an intercooled and a non-intercooled FI setup, at the same horsepower?
Intuitively I would think that there'd be very little difference in pressure or temperature after ignition, which is when all the stress is.

non-intercooled "boost" is far more detonation prone than intercooled "boost" for a given pressure level on a given engine.

Ha!
Difference???? Absolutely none, nope no difference. I'd really know about that one.

Tom ran around here in Texas with a non ic'ed 3Ltc for like 5 years before it gave him ANY trouble  hehe, just giving you a hard time, dude, Tom, there's someone from Kileen, TX looking for you in the southcentral forums, I told 'em you might be around for a bit. . .  Off the topic, are you still planning a July 4th weekend thing up there??? If it's fridayish, I might convince the misses to come up, or maybe I could convince her that I "need" to go to Kileen for a bit, check your baby out, now that's she's purrin' nice and sweet. . .

But colder intake temps will help you better control WHEN ignition happens. Hotter air (which happens when you compress it) will ignite easier. If it is igniting too soon, then you will have problems with detonation, which will definatly affect durability.

On Friday night there is a Test-n-Tune and an import shootout. However, they wont let me race in the import shootout because I have a Ford So that means I have to race the tricked out mustangs, camaro's and firebirds...meaning I'll loose. They have a fun-n-grudge match on Saturday that I think is bracket racing, but I'm checking to make sure. If that is the case, anyone with consistent times could possibly win. That would work out well for me since Friday is the 4th and I don't think I'd get a big turnout because of it. I don't mind either night, but lets talk to people and see which night is preferable.

So if I apply non-intercooled boost to an engine with a compression ratio of 11.5, I'll have to use 129 octane fuel.
Maybe a mix of methanol and diesel would work.

So how much does an intercooler add to the cost?

Depends on what it costs for you to buy it.  A streetflight unit will probably run you ~$800 for everything. It's worth it though, you could spend $800 on mods for your car and not get as much power as you would from the denser air provided by the intercooler. Ever drive your car on a cool morning and then drive it on a hot afternoon the same day? Notice how much more powerfull it was in the morning? Thats denser air, just what an intercooler will do for you. People will talk all the talk about bigger filters and MAF's and whatever, but ask anyone and they'll always agree that a cool morning probably yields better results than a warm day with all those mods.
