Not meaning to remove anything..do you have the clearance to mount it on the front as below link shows?

Just need a longer center bolt and three longer M8 bolts to center the trigger wheel plate ?

Joreto, when tuning EVOs the most destructive knock was when suddenly lifting off from full throt. to avoid it all the cells should have as little variation as possible

Jay, I don't see how they can have little variation, one moment your doing 1 (200kpa) bar and are at the top of ignition and fuel table (say 17degs and 11.5:1), then you lift off and for a fraction of a second you go into vacuum (20 kpa) in the bottom part of the table (40 degs and say 14.7:1 afr). Tonight if I don't forget I'll post part of the log.

yeah even on my w124 m103 u can see in the vid below that most power is made before 6000RPM and then it trails off from there. u can see it most in third when looking at the speed and how acceleration slows.

A turbo'd M103/M104 should make max HP around 5500-5800RPM with max torque at 4000-4400RPM.

Pushing the band to any higher of an RPM range makes for a result that causes stress on all the components of the engine and doesn't achieve a thing.

true, i should have said that what u should have in the low load cells is timing set just abt lower than those of the high load cells. the trouble here is that it means u need to tune for the load cells u hit on WOT. ill try and get more info from my friend as he is seriously into evo tune.

Say u have 17' at 200 kpa,then try and have cels from 130 to 200 no higher than 17.
can u e-mail me ur map?

Good news, I just became the owner of an m104 980 engine and will start work on the car this Saturday !

Jay, I'll email you the map tonight when I get home .

Now you really have my attention. Are you intending to run the standard compression ratio on the M104 engine?

For about a month now I'm running a restrictor as specified by garret, before that I was running without one. Without the restrictor I've have also done many 0 -top speed runs and didn't have any problem. Oil temp was ~100 degrees Celsius (~ 212 degrees Fahrenheit) on the last run. This Saturday I'll take a better look at the engine, pull the head, pistons etc for inspection , hopefully I'll narrow down the cause of the failure. The new m104 980 engine comes with an oil cooler which I intend to use.

Have another question for the boys with manual transmission, what clutch setup are you using in order to hold the power ? Since the clutch is out, I was thinking about a twin disk setup, or would a stock pressure plate with a 3 or 4 puck ceramic drive plate be capable of handling the TQ/HP ?

ed, that is probbably the way i will go, when roman sent me the kit, i followed his instructions, i will have to make another bracket for the sensor.

joreto, my clutch is a two piece sachs one i brought from roman, it seems to be very good quailty, but was very expensive.

there has been a thread on hear recently about a much much much cheeper two puck casstet type clutch, wich was around $300, i felt like crying when i saw hpow cheep it was .

dont think std clutch will hold much, but i am sure that a bmw 6 speed manual clutch could be made to work,. wich may take more power.

"some mods improve your car and make it into something it never was, other mods, however, although essentially the same, are not, and make that car a ricer"

if your car isnt shiny, you dont know what you are talking about, remember; paint shine = knowledge. In order to be taken seriously, you should spend all your money on paint, (and get a dyno reading).
Dont forget to polish it often

Hello everyone.

I am just a dreamer who dreams about turbo charging his 300SEL M103. and just wanted to thank you all for the tons of useful information you post.

I've read this thread post by post, and its like going to school, with each post i learn something new.

Because of this thread i now have much more hope and confidence that i can turbocharge my ride.

Thank you all and Joreto, Man im sorry for your m103 loss and i hope the new m104 will come with a better luck to you. wish you all the best.

Nick, that quartermaster is a very good clutch. I say you made a very good choice when you got it. Personally I'm going to go with a custom made two plate clutch.

Osama, thanks, hope that the number three engine is the lucky one :-D .

Bahamius, I'm going to run the stock compression with low boost ~ 0.7 bars (~10.15 psi). This should give me an effective compression of 17 which is what most tuners recommend for a street car (actually between 16 - 18). In my opinion, setup this way it should be plenty quick and very reliable... but time will tell :-D .

Hi Joreto,
This is my opinion on how you should approach the twin cam. (I would do this if it were a single cam motor as well.)

I would O-ring the block, get pistons that lower the comp ratio to 7.5-8:1 and add water injection.

I would also be using 7 or 8 heat range ngk plugs.

This will give you the best chance of having a reliable engine.
Using a motor with 10:1 comps just gives you no head room for mistakes. It just won't survive any detonation.

Also reading back over your first posts you had a lot of detonation on the early tunes, chances are the damage was done then and it was just a matter of time until the engine let go.

Roman from memory runs E85 which is easy to buy in his country, can you use this fuel?

Joreto, promise us all you won't get all excited (you said gloves off or the like, a bit back regarding the new engine remember lol) & go higher boost than 10psi. Keep it cool man 10.1:1 @ 10psi is still very respectable boost

__________________

um.....why have men got nipples

Oz 300te, yes I had some issues with detonation due to megasquirt settings but they were solved a year ago, also when the bearings were checked they were fine. As to the compression ratio, I prefer higher compression with low boost for a street car since it's a lot more drivable. The 2.5-16v engine had it's compression lowered (8.0:1) and frankly speaking until the boost build up it was a pig. Don't think I'll have any problem with 10:1 and 10 psi of boost, have friends running something similar on BMWs and toyotas with no problems, you just have to go easy on the ignition timing in boost. E85 is very hard to find in my country, I'd venture to say it's almost impossible .

BAD300, gloves off was for the old engine but since I'm not rebuilding it I'll take it easy on the new one :-D .... at least in the begging, but first things first, have to get the engine in the car and sort the clutch and exhaust manifold. For the exhaust manifold I've got an idea that may make the fabrication very easy. Idea is to just turn the 2 stock exhaust headers (if possible), than fabricate 2 secondary pipes that bolt on to them and join at the turbo flange.

P.S. Also isn't Whipplem104 running stock compression in his build ?
