intercooler

Postby dinorossi » Sat Jul 02, 2005 4:19 am

ok, i never knew that watercooled intercoolers were made until looking at gt4s... is the watercooled intercoolers any better than the normal air cooled intercoolers?

unless you're looking at the 165 intercooler, yeah the wta ones are much better than the stock st-185 a/a.

fmics are just as good if not better, though.

no compression on cyl # 4 = no running alltrac :(

when comparing a stock air to air off a 185 to a stock water to air off say a 185RC, yeah the wta is gonna be better, this is mainly cause with wta it can more effectively prevent/disapate heat soak with the top mount setup (RC prob flows better too though)

but when comparing a/a with wta in general its hard to say which is better, there are aftermarket wta ic's (spearco for example) that can offer flow and pressure drop equal to if not better than your average frount mount

IMO one isnt better than the other, it just depends on your application...a front mount air to air ic is usually best for most but requires more piping which can result in more lag,while a 185RC or 205 wta ic is sufficent for many apps and keeps the shortest path possible

yep as pat says its all about application... they both have their advantages and their dissadvantages

typically wta has a shorter intake path and in turn is better for lag... also water is better at disspating heat.... but ata has its advantages as well

To slightly add too, the FMIC will be more useful around the highways and such while the wta IC will be more useful for those who do a lot of city driving.

Another thing to consider about WTA intercoolers is that if you so desire, you can fill the resevoir with ice and water to obtain intake charges that are cooler than ambient temps, which is flippin awesome.

............i like the way you think................^^^

would it work to put other things that disate heat faster in it? like radiator fluid, or someother kind of liquid? or would that just be a bad idea?

radiator fluid doesnt disapate heat as good as normal water.. its just helps fight corrosion and provides protection against freezing tempatures.

Waterweter is a additive you can put in water that makes it even better.. and adds corrosion protection.

so it really depends on application again, if your going to be driving in winter your going to need some anti-freeze. If not just use distiled water with waterweter

Or better yet just drain and refil before and after the winter :P

put alchohol in the system, that dissapates heat far faster than water

and u'll find that a WTA intercooler setup will have ur less effected by changes in weather (ie intake temps)

Anyone seen this?

I was looking for a st205 chargecooler but this is looking allot better. I like the quick spoolup/short intake path vs. fmic

i got an idea, if u replace the wta setup with like an ac unit type of thing with colder than ambient air charge, would this be a good option or what? i have been dying to find out.

Hrmmm thats a interesting idea, It would take allot of cooling im guessing though. Or even use a a2a or a2w then a A/C system to reduce the strain on the A/C, beause the compresser is going to suck allot of HP.. Dont know how reliable the A/C compresser is to run non stop.

An idea would be using thermal electric coolers (Peltier), with an interesting dual water setup to achive below ambient water temp to a A2W intercooler with just electricity. It would probably take quiet a few amps, if I had a st205 core i might try messing with it. You would need a alternator upgrade for sure... They draw like 20 amps each and i would use a few.

the supercharged SVT lightning's have something similar to this idea, the supercooler system...here is an explanation:

"Traditional intercoolers dissipate heat from the supercharged air by circulating coolant through a front-mounted, air-cooled radiator. With the SuperCooler system, the vehicle’s air conditioning system is used to chill a small storage tank of coolant to about 30 degrees Fahrenheit. On demand, the SuperCooler system switches the intercooler flow from its normal circulation and dumps the chilled coolant into the engine’s intercooler..."
