the question on the AC of the water in a WTA setup is a matter of how much HP it drains, and how much more it will produce. i think ur average AC drags around 10 - 15hp or more of ur power (someone correct me if im wrong and ur CERTAIN or have reference, but im pretty sure). question is, will that colder water produce more than another 15hp by effecting the charge air?
what are teh complications of the system? how much more room is it giong to take up in our already spacious engine bay?
a WTA system is already very efficient, which can be increased by a number of factors:
- the intercooler itself
- the size of the resoviour tank
- the size/efficiency of the heat exchanger/radiator that cools the water
- an appropriately powerful pump
many one run rag coolers use a pipe through a box of dry ice, which is evidence to the case that reduced charge temps can make a large difference, but in said case there is no scavenging
Corky Bell mentioned in maximum boost that his theory was it wouldnt create a great enough advantage to overcome the power drain weith current AC technology, i seem to think he may be rite, considering how well PWR's barrel WTA intercoolers werk
abel ibarra run two on his 6 second rotary
have a look here for urself
