603 crossover tube into an intercooler... - Page 2 - PeachParts Mercedes-Benz Forum

Im going to drag this up alittle (again). Ive found a small fender mounted i.c. on an Eclipse turbo that can be had for $20. It looks like i can mimic this setup. The turbo side can use a simple boot and elbow. The crossover will need cut and welded square to round, and preferably gradually as possible, and not an abrupt taper/bottleneck. Also the factory fender/hood vents would be nice on the SDL.

Why? All you are going to do is choke airflow and reduce power. Do you have an uprated pump? The stock system is quite adequate.

well this will be done on my SDL daily/test mule. the setup, if it works, would be transfered to the spare motor i will be overhauling before dropping in the Land Rover, and stock setup from it swapped back to SDL. I agree that on these cars an intercooler will probably not help anything, but yes, the other will have full load adjustment and be in an overweight full time 4wd, and will see lots of sustained WOT scenarios when wheel spinning in mud holes/sand/ect. So yes, i would, in an ideal situation be able to go where i want, and make it home!

And dont YOU have a huge front mount IC?!!

That eclipse IC looks to be about the same size as the one on my 99.5 Jetta.

It 's not that big but I also 3" tubing which is what you need for 700CFM. In your scenario, you are far better off with an AWIC, a radiator and a large reservoir tank. AAIC is only good if you are moving, I imagine you rarely will be moving more than 20mph when you really need that boost. Before you do anything, add an EGT and see what its really like at WOT.

Is it better to measure EGT or IAT?

EGT is the only one that matters (as does EGP but both are coefficients of each other). IAT post turbo and post intercooler will tell you the efficiency of the intercooler, pressure before and after intercooler will tell you the deficiency.

I plan on using one of those overboost solenoids to measure before and after pressure and only use one sensor, alternating between the sources.

I have a pyrometer. but ya, you have a point about the low speed and the lack of airflow....hmmm.

So I've never seen a pyro on a stock system. What kinda max EGT are you seeing?

300SDLandRover · #26 09-21-2013, 11:23 AM

I installed it post turbo,(work on semi trucks, thats how they're mounted,before visiting these forums, didnt think to mount in manifold) 0-60 run WOT will run up to 600* which according to best guestimates would yield 900* or so? Cant find anywhere i can push it farther. Really want to try a water to air intercooler now that you mention it, and weld an inlet on the opposite side of intake like yours. Maybe next year with taxes...

The awic I bought was under 200 and sounds like you can do the welding yourself. I really think it's the ideal way to go.

Ya it does. I found a nice one for $149. I have a good sized heater core from a semi with dual electric fans mounted on it, and a massive Edelbrock fuel pump i can use, all i would need is a plastic overflow tank from a wrecking yard!

I would use a much larger tank in the trunk for some real power. Also the SLS tank might be a nice fit!

The Land Rover Discovery has a (no bull****) 3gal WASHER FLUID RESEVOIR. Just got a ARB bumper off one at my wreckers for mine, woulnt be too hard to mount where my LR air filter box is now, (intake side would be reversed with OM603 swap.)
