Mr Smooth your wife is right, crazy WTF. That engine looks brand new.:cry: Anyway all the best on your build, I will make up the new label for your engine just scan and send me your signature....Will also read, "Proudly South African, 1 of 1"

At least you didn't have to strip your BMW engine to make power...Lol

Phew this is a huge built. :thumbs:
Removing that engine looks so easy. Great support staff you have. Well done GS.
I see a monster in the making. :praise:

Is there a build link maybe to the BMW build? This is brilliant,would love to see your other build!

The information is scattered all over the forum. When I got some time will compile something.

First order of the day was to remove the wiring harness and then the intake manifold along with the injectors and fuel rails. Was pretty straight forward. Once removed it looks like there is nothing left of the motor.

The inlet manifold.

We then went ahead and stripped everything of the front of the engine. There are quite a few interesting channels left.

Valve cover off showing the camshafts as well as the variable cam timing adjusters.

This is the point we got more or less stuck and where the expensive special Mercedes tools are required. We sorted most of the cam placement problems etc without needing the tools but with the cam adjusters pictured below a tool is needed to hold those fine gears together at a exact place prior to removal. We pondered for a while and devised a home remedy which we will be attempting on our next engine strip session.

Since we had some prep to do with the cam removal we spun the motor around and removed the oil sump. We where really shocked when we saw the size of the oil pump. The oil system is overkill in this car and the oil pump alone weighed close to 5kg. My engine builder mentioned that after seeing this the dry sump system on the SLS was either fitted to lower the motor or for just having something nice on the sales prospectus.

At this point we called it a day.

Looking good , it is easier with the lifter .

I helped a guy pull a bm motor , problem was he put the strap around the cross member ...wondered why the wheels lifted off the floor :roflol:


George , a few questions seems that nobody has had the courage to ask :

Are you looking at 1000 hp at the reef ?
How efficient is the build power output at the reef as against the coast , i.e. percentage loss maybe 3% or so ?
Are the bore and stroke sizes remaining standard ?
Would the bore withstand higher pressures /temperatures if bored oversize by say 1-2 mm ?
Thanks

The goal is 1000hp at the reef. The charger flows enough cfm to achieve this with a bit of charger rpm to spare.
The charger will be cranked just enough to achieve the 1000hp. How the power will be measured is unknown at the moment although two cars have shown in access of 850whp in the states at a set boost point.
The bore and stroke are remaining standard. I am not sure about the oversized pistons because at the moment there are two cars running stock bore sizes. The one has Darton sleeves and the other on the stock block. Both are handling the power. The gaps between the pistons are very fat although further down there are some water channels that are even closer hence everyone is avoiding oversizing.
The altitude losses at a set pulley size will most probably be in the region of 8-10%. On peak I will have to use different pulleys if I need to go to coastal regions although the fueling is set to be overrich to compensate for this the power output might go up to high for the engine components.
