Dieselboost's 524compoundTD

and why are the regular MLS gaskets coming as 2.3mm compared to the stock 1.87mm. why such a difference, does the comp ration get too high?

it depends lot of which kind of engine you are building...

if compression rate is lower than stock... you can use higher higher boost... like over 2.5bar

and this helps a lot with cylinder head flowing...

we measured that m21 cylinder head flows about 145hp in stock condition... but my head flows about 250hp easily now...

but main reason to your question is that i had no choice... my friend had one spare mls gasket and it was that...

Just got ready engine room section electrics...
NO more shitty wires etc...

now engine room needs only paint job for boost pipes, finishing for the fuel lines etc...

after these mods i will bolt on my bodykit and beige leather seats

after all this... i will make real photoshooting with my friend who is professional Photographer.

but i say... car is not made with with big money today... and it is not show car... it is just made for fun and weekend fighter and actually for daily usage in summer...

so there are few not so cool thing in it...

I have now read this whole thread and also checked out all of your pictures in the eyecandy section. Very nice project and car i must say! Looks almost like my 524td, same paintcode and then i've even got a set of Breyton magic 19" rims that looks almost like yours except from the "splitwheel bolts".

I have a similar project going on with my car, but don't worry it will be repainted in another colour and use other rims.

Maybe i will put up a project thread in here later on.

@Pipewelder: Please post up your project! I really like the idea of these High power diesels!

I'm very curious on how your new fuelsystem works.

That's one thing that has annoyed me for long time, the stock filtering when there is airbubbles.
Update us!

And Jelmer538i: I'll try to get up a project thread soon. I really love the 524td's and it's real nice to see that there are serious people tuning these wonderful cars!

it really works... i have tested it littlebit... no air bubbles anymore...

need to check my fuel pressure when i get gauge on it...
i will report later when i know more...

Hell yeah... car is inspected now... and taken to road use...
just cruised about 150km today!!

everything works just how i wanted, boost is 0.5bar but later i will use 2.5bar...

DieselBoost · Post by **DieselBoost** » Apr 09, 2013 3:17 PM

Hell yeah!!! i DID IT!

we got an leaky mls gasket.... with daily driving and 1bar boost

i think this is caused by failure in bloc deck surface... or leak between layers of mls gasket... which i dont glued...

Pipewelder · Post by **Pipewelder** » Apr 14, 2013 2:14 PM

Congrats! Or what should i say..

It sounds like the issue depends on either block or cylinderhead surface. What i've heard the MLS gaskets requires very good surface finish to work. Some poeple says that you have to glue, and some says you don't have to. But the surface finish is quite important to get it seal properly. This by experiences on gasser engines, but the same should apply for the diesel, if not more important than gas engine.

DieselBoost · Post by **DieselBoost** » Apr 16, 2013 12:33 PM

i have some ideas about this...

my cylinderhead was better than new one... and never used...

but that block or.... hard studs caused this by aluminum head thermal expansion...

and i used vht copper gasket glue... that i always use...

mls gasket with elastomer doesnt need glue...

there is some good info in the turbo section about MLS gaskets. I'm sure you know what your doing because your work looks good. A lot of guys had leaks when the surface of the head and block weren't at a mirror finish.

yep... that is irritating to know

Holy moly... i just found that crank bearings and connecting rod bearings and piston ring are not so expensive what i thought...

so i say hell yea... i will get my fully machined flame ring block from storage!

DieselBoost · Post by **DieselBoost** » May 08, 2013 11:51 PM

just got cyl head back on place...

i cleaned old mls gasket surfaces and glued it between the layers...

tomorow i will do some tests... hope it will work

DieselBoost · Post by **DieselBoost** » May 15, 2013 5:51 PM

It works again...
