Radiators: Is 22" enough for 400 HP?

Eastwood company is marketing a radiator they advertise as a tri flo model. Claims your coolant will be 25 degrees lower using this radiator. Basically the is sectioned off 1/3 of the way down on one side and 2/3 on the other. The theory is since it is a cross flow model the coolant has a total of 3 passes thru the cooling area.
They have been selling them $200 all sizes. 22" 26" and 28" are available

Interesting. That's pretty much my budget. LOL I'll have to check it out.

long story short I started with the slightest of upgrades (several fans, water pumps,thermostats,shrouds, radiators) and now I ended up with a 26" radiator and a Ford Taurus 2 speed fan. You never know when your going to be stuck in traffic or car cruise watching the temp gauge creep up. You start calling friends asking if 230 is ok. Second guessing your 160 stat. Your kids are in the back "why is the car smoking daddy"

Yeah, I saw quite a few people here do the 26 inch + Ford fan setup. Looks like a nice setup, but I'm worried my stock alternator won't keep up with that fan.
