(04-22-2010, 11:13 AM)jonbobshinigin Well, this is a primarily, if not entirely Mercedes diesel board. What vehicle are you interested in learning this for?

Generally, "Holset" seems to be a very popular brand for Turbo upgrades on these cars. Typically they come off of Cummins engines. Most of our cars already have a turbo and when we want to upgrade, we adjust the car to give the engine more fuel FIRST, then we worry about adding a turbo.

Raw vegetable oil does not run "clean" in an engine.

(04-22-2010, 01:09 PM)Rcdevil i meant as in emmisions, but yea i know that if it does cause some clogging.

(04-22-2010, 04:14 PM)GREASY_BEAST Welcome rcdevil. I ran SVO for a few tens of thousands of miles in my 300TD. The key is to design a system that has separate fuel filters, heats the fuel all the way back to the tank, and ensures that diesel and SVO never mix. You should not switch to SVO until the fuel temperature is at least 130°F and the system should run at least 160°F after its fully up to temperature.

All these concerns pale in comparison to the filtration. You must ensure that the fuel going into your tank has been filtered to the micron rating of your fuel filters, otherwise you will not be able to drive very far. Furthermore, you must ensure that the fuel is 100% devoid of all water. This is the most difficult part.

(04-22-2010, 03:39 PM)ForcedInduction That "french fry" smell coming from the exhaust is pollution that happens to smell pleasant.

Proof?

(04-22-2010, 07:59 PM)willbhere4u The exhaust is just for is noise it wont make a difference what fuel you run!

The only difference is that the straight pipe is a lot louder! http://www.youtube.com/watch?v=duSWb2v1inc

As far as smoke goes a car can be tuned to run clean no mater what fuel you run on! my 240 makes almost no smoke at all and it runs on 100% pure diesel! with a straight pipe!

(04-22-2010, 08:37 PM)Rcdevil are you kidding me? exhaust isn't just for noise it is to clean and filter the emissions...

Ah Grasshoppa, remember these are diesels, not your gasser...forget almost all you know about gassers and come to the dark side.

(04-22-2010, 06:49 PM)TotalDiesel SVO Is Co2 Neutral. Meaning that the plant in which the oil came from consumed the Co2 from the atmosphere. The oil removed from the plant consists of carbon taken from its environment. So when you run vegetable oil, you are only returning that Co2 to the atmosphere as it was before. PetroDiesel releases larger amounts of carbon which existed millions of years ago. When we burn fossil fuels it releases more carbon in the air, Obviously. Thats why people feel that crude petroleum is the cause of global warming which adds more co2 to the atmosphere. Waste vegetable oil simply keeps a stable Co2 level when it comes out your tail pipe. The only pollution factor would be how efficient your engine is. Its definately not good for the environment or anyone when a cloud of black smoke is trailing your vehicle.

(04-22-2010, 09:41 PM)Rudolf_Diesel No problem, the newer diesels are using cats and DP filters, but these older ones don't. The more free flowing you can get the exhaust the better. BTW, stop staring at my avatar

(04-23-2010, 09:07 AM)TotalDiesel Diesel turbos typically double the output pressure of gasser turbos and more because the engines are strong enough to take the pressure and theres no need to worry about knocking.

(04-23-2010, 10:59 AM)Rcdevil so when shopping for a turbo i will have to look for a diesel turbo, right?

There is no such thing as a g@s or diesel turbo. Turbos do the exact same thing on both types of engines, you just need to match the turbo to the airflow and pressure ratio you need.

(04-23-2010, 08:08 PM)Rudolf_Diesel but a diesel will not be as hard on the components.

(04-23-2010, 08:08 PM)Rudolf_Diesel but a diesel will not be as hard on the components.

From a thermal standpoint without a doubt, from a work-stress view they are probably about even. I'd say a g@s engine is easier on them since they spool up infrequently and to much lower pressures, but they have the sudden compressor flow shock of the throttle frequently closing (even with a relief valve).

(04-24-2010, 08:30 AM)Rudolf_Diesel I am not sure if I would bother with a gasser if I couldn't run high boost, what's the point?

(04-26-2010, 12:33 PM)dropnosky yeah, WTF? I can't believe you would replace it with the chick from charlie and the chocolate factory. (I think)

That is Veruca Salt of Charlie and the Chocolate Factory.

On a side note, the Band of the same name on was pretty cool back in the day.

(04-28-2010, 12:26 AM)George3soccer owned a w124 with a 602.

nice looking w126, sure wish that would be a diesel under the hood. most likely not.

(04-28-2010, 10:03 AM)garage Best advise that anyone on this board could give you would be to read, read, read, and then put that gained knowledge into action.
This is one of the few(if not only) forums on the internet that is dedicated to not only these old diesels, but tuning these old diesels.
Theres a wealth of knowledge to be learned on here.
Ive read every dang topic(almost) on this site and still learn from it everyday.

And by the way, if your interested in seeing everyones views on running veggie in these cars you should go check out the Alt Fuels section of the board!

(07-26-2010, 10:58 PM)Rcdevil no actually i just turned 15 in may.

and also sorry to be the bearer of bad news........ but im really sorry to say that i will most likely be getting a vw im not out of the whole mercedes thing though because i still think its awesome but for it being my first car i mainly need the mpg for going to and from school. but trust me there is still a spot in my heart for a diesel mercedes as there is nothing like one and my dad also has a 560sel and a 560sl so i still get reminded of them every day. and yea, just wanted to say that im not just gonna move on from you guys and this forum like some people have.

hope you guys can understand

(07-28-2010, 12:06 AM)Rcdevil mk4 tdi
and thanks for suggestions, probably gonna do it, and yea ive been on the vwvortex forum and am gaining more and more info on the mk4 golfs. and also its gonna be in the style of vw vortex and will probably be lowered and etc.

thanks,
