Twin Turbo Intercooler Design

The 1UZFE EGR Delete Kit is available for sale here.
Not a bad design and there should be less pressure drop with this type of design. I have seen intercoolers like these before but they were for LS1 turbo kits.
 
Can you describe your set up? For now, I am going to assume each turbo is collecting from each side.

I think a better design would be two separate intercoolers joined at the outlet via a y merge to minimize some of the turbulence. Space is a commodity so this might not be possible.

It's a decent design but not ideal. The inlets may have some terrible turbulence and backflow.

P.S Only one S in Sponsors, (not Sponssors ;) )
 
Lex, i wouldnt use the 2 seperate chambers on the intakr side, i would just use 1 full chamber, same as the out let. With this design, you would not get as equal a spread across the whole cooler, but if both inputs were pushing against each other, flow thru the cooler would be much smoother. Also, try to stay away from box style end tanks with very high boost ( i dont know how much you plan to run ) as the welds can blow out. Better off with rolled end tanks, much stronger, and much higher flow.
 
The other way.

This is how i did twin turbo set up with a garret bar and plate intercooler the plenum is fitted with 2 throttle bodys and the intercooler is divided in too 2 halves. with shaped end tanks to help with flow the cooler is 600 x 300 x 110.mm.
and is capable of flowing 800 hp.

Choice number two with dual intake:

For twin in/out design, you are better off using the 300zx style intercooler, not so many changes in direction of air flow.
 
His statement is very general. It depends upon the distance, style of core and the amount of air that you can pass though the core.
 
Which IC below would be the optimal choice with twin turbo, dual intake?

1. Side By Side: Two In, Two Out

2. Top To Bottom: Two In, One Out

3. Top To Bottom: Two In, Two Out

Not to hijack this thread, but I see that Taffy is a dealer/reseller for Darton, the people that resleeve engines.

Taffy - can you contact Darton about the feasibility of resleeving the 1UZ?

#1 That's the design with the least possibility of the air flow changing in direction. You probably don't need the 3 inch outlet. The same diameter inlet and outlet should be fine.
 
I don't know much about intercoolers but if anything wouldn't you want the outlet to be smaller than the inlet (as opposed to bigger) seeing as the air is cooler and therefore denser? A bigger outlet would only slow the air down making it more laggy I'd have thought...
 
Definately option 1, for much the same reasons i said before, and that verylost has said.
Damien is also correct, both inlet and outlet pipe should be the same size. Yes the air is denser on the outlet, but it is still being pushed by the less dnese air enterering the cooler, so speed will not vary there.

Just to make things interesting, have you considered water-air coolers???????

Unless lextreme has some secret trick to cool the air to near freezing temperatures, the difference in inlet and outlet diameters is minimal.

I just suggested he stick with the 2.5 outlet to save some money. The difference in size should have minimal effects on cooling and performance.
 
Andrew,

Great find. I read Corky's book few times already and he specifically stated top to bottom is more effecient than the traditional front mount.
