Intercoolers
Intercoolers
Experts;
I have already bought an European exhaust manifold and a Holset HE341Ve for my 1987 300D turbo. The next on my list is an intercooler. I have read a lot about different kinds. Some recommend a thin one (1.25" think) blocking the radiator. Some recommend a small but thick one (4") hanging low and blocking a small part of the radiator. What is your recommendations?

PS: attached picture is the kind of set up I am going for, off course the exhaust manifold will be different.
PPS: do HE341Ve and HE351Ve use the same elbow?
The thicker the intercooler the less efficient it will be. The ambient air heats as it passes through the core, by the time it reaches the back of a thick core it can't absorb much more heat and part of the engine air remains hot.
A large thin intercooler is much better than a stubby thick one.
Here is a chart from a TDI that compares a thick aftermarket side mount intercooler to a thin front mount intercooler.
341 and 351 vgt turbos are very different. They have little in common other than the same oil/drain ports and a 4" air mouth.
Yep. An intercooler will put less heat into the radiator air than the A/C condenser would.
