To Ortolan&PUMPISH:
Did your AT&drivetrain being reinforced??
Because Im really worry about the stability of them.
Or you guys never care about that

Like the video I watched,the rear rubber coupling would be destroy by the torque

And I think the gear clutch of AT would be easily slip while you driving under maximum torque in the low gear

Where can I find a set of AMG 3.6L Crank&Conrods&Pistons in a good condition,Ortolan?

I had my AT rebuilt with OEM high-torque parts. Hopefully it'll be enough, I'll know soon.
If you want to build a 3.6L monster the best way is to buy a used C36 engine on ebay. If the rods need replacing I have a set of new rods being sold cheaply. You can then have some custom pistons made up.
Doing it this way would have been far cheaper than the way I ended up going.

US$300. They're sitting somewhere in my mechanic's workshop. I'll pick them up when I'm next there.

About drivetrain you can easy make aound 400Hp with stock drive train and GM clutch plate but more then that the problems will come.

Now I use sasch racing 2 plates clutch kit for 1200nm
And no rubber flex joints, I replace them with knotcross and special builded tranny so I hope I can make up to 1000Hp with this new setup

1000HP?! Whoooweee! Really? We'll be waiting to see some video of THAT!

Thanks for the information

But Roman,
What type of manual tranny of you use?
W202's 5MT?
W201's 5MT?
W124's 5MT?
I think the limit-strength of these 3 types would be diffrent.
The MT maybe stronger than AT,but so much torque would be a biiiiiiiiiiiiiigggg problem for a tranny.
I mean in long term,the clutch may able to receive,but the tranny inner components too?
And Merc's MT had a problem,"too much shift stroke/un-convenient paddle layout".
Does it can be solve?
Im consider about to swap a V12's tranny components to a 722.5 tranny,with carbone clutch discs.
Or,find a rare 722.6 tranny for it(only able with M104 3.6L/2.8L).
Why 722.6?
Here,in my place,many 55K+722.6 tranny can up to 800PS+&950nm+ without any tuning for tranny strength,and they often drive over 200mph without any problem.
Do you think it's a good idea for the tranny?
The idea of crosshead joint for driveshaft is great,I agree this is a final solution for the hell rubber joints.

Where are you, Roman? What's happening with that hot rod Benz?

The G.F.P · #12 02-05-2008, 10:48 PM

wow!

ive seen romans youtube videos ages ago and regularly show my cossie mates his video and the whole time he is on the ssame web site ive been for almost a year

the man is nuts

im anxious about trying to get 400bhp out of my m104 twuin turbo let alone 800bhp

ive only read the 1st few pages of this topic so far

just herd they have m104 TT conversions left at beaconsfield so im tempted to make my amg styled coupe a twin turbo too

Roman, what is the reliable bhp that could be made on a stock m103 turbo engine. I'm asking since I trashed my turbo 16v engine (broke the num. 1 stock con rods at 1.3 - 1.4 bar. Topic about the failure http://community.190revolution.net/drivetrain-performance-modification/32338-2-5-16v-turbo-engine-failure-rebuild.html ) and now I can get a m103 983 engine . Plan is to leave it stock i.e. 9.2:1 CR and turbo it with the parts I have - t3/t4, Megasquirt and so on . Could I get 350 - 400 hp reliable bhp from it (want to make a fun daily driver till I rebuild the 2.5-16v) ?

P.S. also what is the max boost you would recommend for it to be reliable ?

You went into detonation and destroyed the rod. you needed to add fuel.

Gus was killed in an accident, he will be missed.
