08-18-2010, 01:51 PM #1OM 617.951- At the spot where the turbo connects to the intake manifold, there is a connector piece inside there that looks to be fairly restricting that passage from the turbo into the engine. If one were to remove that piece from the inside, and replace it with piece of intercooler boot around the outside, would that help airflow into the engine at all? Or just be a waste of time/money? Thanks.

No. The tube is actually a cone that gradually tapers from the turbo's ID to the manifold inlet's ID. Removing it would introduce an expansion chamber and lots of turbulence.

I thought it would do something to the airflow, but wasn't sure if it was towards the good or the bad. Thanks for the heads-up.
Hey Forced, you say you work as a (Diesel?) mechanic for a Trucking Company right? Where'd you go to school for that?
I'm looking at Wyotech in Laramie. Hear anything about that place?
Thanks Guys.

I have heard good things about Wyotech and if I could get a do-over it would be my choice.

I went to DADC (now Lincoln Tech). The initialism "Denver Adult DayCare" is accurate as it was mostly (99%) high school failures with no actual interest in the field. I would not recommend it to anyone.

I went to UTI (Universal Technical Institute - Un Trained Idiots) haha But it is a VERY good school and I learned tons there... Wish I had went to the diesel version toooo.

I had heard that the 180* bend in the U-tube on the stock air box is a common restriction point. If that were to be removed and a 180* silicone intercooler boot clamped in it's place, would there be any gains to be had in doing so?
Also, what is the diameter of the airbox output and the turbo intake?
Thanks.

Yea, I was debating doing that. I just spent $15 on a new air filter bracket though so i'd feel kinda guilty just scrapping it. I've been wanting to do a set up like FI's for awhile now, just havent really gotten down to it. Where might I find a air/oil seperator for the crank gases anywho?

No. If you notice its a pancake shape that aids in reducing flow restriction by keeping the air's velocity more stable from the inside of the angle to the outside.
Quote:Also, what is the diameter of the airbox output and the turbo intake?3" and 2.5".
Quote:I just spent $15 on a new air filter bracket though so i'd feel kinda guilty just scrapping it.Sell it.
Quote:Where might I find a air/oil seperator for the crank gases anywho?There really isn't a good one available that isn't extremely overpriced or very undersized. Most people have made one from a PVC tube or 1/2" airline water separator. The one used on 81+ 240D models is primarily a crankcase depression valve instead of an oil separator.

I recently installed a 8038 filter with a 3" "street" 90 degree ABS elbow and a 3"to 2" rubber reducer to the turbo. I thought it whistled good with just the straight pipe. Daaamn it sure got better, and that turbo spooling is sweet music... Thanks for all the helps guys. Pixs to come.

There is nothing wrong with the 8038 but the 8037 is larger and fits on the tube without having to enlarge the filter mouth.

Yea, the 8038 is a tight fit in the SD w/ euro lights, i'd believe the 8037 is even tighter, and may actually not fit. I didnt have to enlarge the filter's mouth though, just used a little bit of silicon lube and that generic elbow grease stuff...
