Novice Intercooler question

Dear All,

My Turbo charged OM616 (18000 Km) does not have an intercooler.

People claim that adding an intercooler adds about 10HP to the engine

1) Is this 10 HP figure true?

2) Where will this 10 HP show itself, at low rpm or at high rpm. In other words , will the car pull more or go faster?

3) I plan to put the Older Mercedes Transit van's Intercooler as an intercooler for OM616 is not available in India. Can an Intercooler be too big ? can a big intercooler cause any problems.

4) Would I be wrong to try to use intercoolers from other engines that are smaller and therefore easier to install, Like peugeot 1.3 L . What are the precautions I must take.

5) Would any one advice against adding the intercooler for any reason.


Thanks in advance.

Ram

their is a set of calculations for determening the size of the intercooler(someone chime in here), i noticed in your pics that the turbo would have to be "clocked" to get the output of the turbo posistioned so tubing for an intercooler can be added, also if you turn the boost up you need to turn the fuel up.. and a turbo charged 240D.. is something new for many of us i bet.

1: No. You will not see any change in power until you adjust the max fuel setting inside the injection pump. What you WILL get is lower Exhaust Gas Temperatures. This is what allows you to turn up the fuel without melting a piston.

2: After the max load setting is adjusted, you will see more power anytime you are near full boost.

3: Bigger is better. The more area you have, the closer it can get the intake air back to normal air temps. The only downside is slightly longer turbo lag, but it will barely be noticeable.

4: A small intercooler is better than none.

5: No. All diesels should have an intercooler.

Is the max load setting able to be easily changed on these Injection Pumps?

Well, all TURBOdiesels should have them anyway... Show me a 2007 model-year passenger car diesel that does not have a turbo.
