Twin Turbo Ls3

[exwestracer]

I'm all ears (ok eye's..LOL) and do appriciate your input...
I know that water is a better heat transfer medium than air(hence smaller turbo intercooler).
I agree that once you get the heat into the water, you now need to pull it back out using air (1:1 heat transfer with a bigger radiator)

I haven't done the math but most radiators I've seen don't use the same size as an air/air intercooler.



Also max 1:1 heat transfer would be based on 100% throttle all the time at max boost. I don't know too many that would plant the throttle with 800+hp 100% of the time? Road racing on the big track at Willow I might see full throttle on the front/back striaghts for less than 10sec? 145mph

example: 600-1200hp Radiator

Good info here: http://www.bellintercoolers.com/page...FAQ.html#FAQ_5

Of particular interest is the last half of FAQ #5... They sell both, so I figure that info is about as un-biased as you can get... My comments were based on a direct comparison of inlet charge temperatures vs heat radiating areas. Obviouly, each type has it's place.
