Have you done any testing as in measure and compare temperatures?

Interested to know what the inlet temps are?

Do you have a FMIC too? Im just trying to figure out why you still have a hardpipe coming out of the fender.
Also where did you mount the radiator for it? Where are the lines? Pump?

Im also with these guys.. Right over the turbo isnt the best place for the heat exchanger.

yea i thought the same thing about having it right over the turbo
there isnt much space to mount an a2w intercooler so i found a place where i did have a bit of space
it fits perfectly but i'll need to insulate the turbo and intercooler as much as possible

if i didnt think it would work then i wouldnt have mounted it there in the first place
perhaps using ceramic will be my best bet

the intercooler radiator is mounted where the stock intercooler would have been...
its also a 2x1 foot radiator...which BARELY fits with some modification

Search IJ.'s posts. He had an a2w setup for a while.

Yea im sure you could isolate the IC from the turbo a little better. Maybe you could get some heat shielding blanket to wrap around it.

Why is the IC pipe still going into the fender? I would think you should just curve it up from the turbo right to the IC for the shortest route possible.

I think with a good volume heat exchanger, it will be more efficient than most of you expect... IMHO with a good heat exchanger it will be far more efficient than a FMIC.

edit: in regaurds to gotsomegetsome's setup

haha you know i spent hours trying to find IJ's profile but i suppose those who are patient turn out to be more fortunate?


im not done with the setup. Ive got some exhaust wrap thats only the cloth one to go around everything but the turbo itself, but some aluminum coated or something like that wrap for the turbo...its like a button on blanket but not as custom fitted.

so far ive ran the engine for ten minute intervals from cold starts and the intercooler amazingly doesnt get that warm at all... i would have expected at least a bit warmer temps but it really is only warm to the touch

the curve for piping wouldnt be the best thing for flow... 180 turns with radii less than 6" are a bit restrictive. I cant turn my turbo pointing up if thats what you meant also. for some reason I cant find the pin or whatever it was that lets you do that so I just left it... and cutting the pipes and all wasnt that big of a deal. took most a day to complete with minimal power tools


however, if you guys could help me out, Im having problems with my BOV. its a type H connected to the pipes by the intake if its shown in the picture. for some reason with or without a vacuum connection, it simply wont open. I believe it has a 12lb spring but the valve should open anyways i though....

perhaps i have the wrong vacuum tub hooked up? it is connected to the original bypass valve vacuum tube

okay heat rises in situations where the liquids carrying it are not contained
so when at a dead stop for extended periods of time, perhaps, perhaps the heat will sink to the intercooler provided the turbo is not insulated from the intercooler

thermodynamics states that heat will travel from higher concentrations to lower concentrations however for this to happen, the medium must transfer the heat to that other concentration. unless the turbo is giving off infrared radiation...which i dont think it is...then this should be fine

I come from a land down under
You've mounted it in the HOTTEST part of the engine bay full stop....

Will it work.. yes will it be efficient NO, why on earth bother going to all this complexity and added weight to be a less than efficient system just for ease of packaging?

ease of packaging? it was never about that...
if i wanted that, then i would have gone stock

its not that its mounted next to the hottest part of the engine compartment
the original pipes go right above both the turbo and exhaust

so what your saying is that any setup, stock or aftermarket, would be inefficient
therefore, any setup that removes heat from the equation should be more efficient than any other setup unlike it

Are you stupid or just arguing for the sake of it?

What happens when you put a pot of water over a heat source?
