Hehehe. An effort to reduce the intake air temperature to ambient should yield a lower exhaust temperature, allowing for a greater amount of fuel to be burned before the engine reaches a critical temperature. Done right, an intercooler coupled with a reasonable fuel increase may be MORE reliable than stock due to lower exhaust temperatures.

The lag would likely come for that big honking Holset turbo! Sure it'll take a while to spool up but there will be a WHOLE LOTTA BOOST when it does! Looks like the ones on CTD's. Check out the K&N filter. Quick, someone tell them their getting dirt in their engine! RT

I would be sorely tempted to replicate something similar but I refuse to sacrifice my A/C. I wonder if there's room for a custom-fabricated intercooler that is long and narrow, crossing under the bumper & radiator/condenser. Might require an AMG-type spoiler which is shaped different to accomodate such an item. Hmmm... plus, the heat rejected wouldn't go directly into the condenser & radiator. Oh well, I'll probably end up attemping the mini version ahead of the right front tire (a la Mosselman) eventually.

That's one big effen turbo!

Very impressive project.

Why custom fabricate when the parts are already available from Mercedes Benz? The intercooler for the 606 turbo is exactly as you describe. Check your EPC for the 99 E300, in the "radiator" section.

Heh-heh... I know. I think there was one on eBay pretty cheap a while back, I should have picked it up. I suspect it may not fit, might be a little too large in one or more dimensions. The good news is that it's only ~$400 new, last time I looked. I have peeked at my bumper in the past and there is no room with the stock bumper, AFAICT... I'm pretty sure we would need a modified AMG-type to enclose it. Hey wait - I almost forgot! You have a 606 turbo - any chance you could get some measurements next time you change the oil and are poking around down there?

Funny you should say that. The display is screaming "Service Due Now" every time I start it up. Will get to it next week and try to have a peek.

You can get an increase in power by just adding an intercooler. Consider this scenario...

For arguments sake, your turbo'd and non-intercooled car makes 15 psi of boost. The wastegate limits you to that pressure.

Okay you install an intercooler. The compressed air entering the engine is now much cooler and at a lower pressure. The sam amount of air is entering the engine however.

What happens next? The wastegate will try to maintane the same air pressure as before, and increase boost pressure again to 15 psi. Since the wastegate is only controlled by pressure the engine will be ingesting more air than without the intercooler.

this will occur unless your turbo cannot supply the extra volume, or your fueling requirements can support the extra volume.

The rule of thumb is for every 10 degrees of inlet temperature drop you experience you gain 2 percent more power.....

If intercoolers didn't work, then why do manufactures install them on turbo and supercharged cars?

The turbo gets its pressure signal from the compressor housing. 15psi is the same at the turbo no matter if an intercooler is installed or not. This is why when a pressure drop happens across an intercooler the turbo wastegate must be adjusted to compensate. Installing the signal line after the intercooler can lead to a surge (Too much boost).

There was an OM606 intercooler on ebay last month that went for $75--I could kick myself for passing it up. I think that all you'd need to do is blister the lower valance on the front bumper to accomodate the mounting of the unit. I have no interest in all the fancy tire scorching stuff, but it would be nice to increase the overall efficiency of the OM603 with an intercooler and other improvements.

intercooler is a good thing, an we benafit all the way around.

1) aids in cooling air

2) allows more air into cylinder

3) cause ya get more air in cylinder, better power

with just a intercooler mod, you'll notice a slightly better power, slighty lower operating temp's, and with the lower temps, it will last some what longer over all than stock. then if ya what to play, I'd add a water injection system, vs a propane system. I'm in the same mind set as Zeitgeist, not really looking for 500hp kinda power, just good solid power, that runs for a lot of miles, and low maintnice. Just so ya know, I choose water injection cause it's a proven fact than it also helps keep the tops of the pistons clean, as well as the valves, don't know if propane does.

remember, folks, bolting on an intercooler alone does nothing for power. Yes, nothing. You must increase fuel delivery at the injection pump by adjusting the full-load screw inside the governor (NOT just tweaking the ALDA). Then you will gain power. Otherwise, you get zip. Trust me.
