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

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.

You have so much experience and have done so much home work it's frightening!

In awe of the work being done

This is world class even hard core bmw fanatics can appreciate the magnitude of this build

I cant imagine what this car will sound like, but my only doubt is putting 1000BHP to the ground, traction is going to be a nighmare. Imagine a 4 wheel drive 63, it would be a 10sec car if not lower

Awesome awesome build

U can give me the 335i after this is done

Respect, Mr Smooth.

Today time allowed us to get into the serious matters. OB from Chip Logic came over and the stripping commenced.


The variable cam gears without chains and the double gears locked in place. We did some marking with some funky lumenous green nail polish.


Camshafts off. More marking with funky pink. At this point I am wondering how expensive the nail polish I am using is. Shhhhh my wife wont know.


Close up of the valve buckets. There was no visible wear on any of the buckets accept for one which had a irregullar dimple. I am happy I am upgrading these.


Proof that even a naturally aspirated car can do with a oil catch can. The amount of grime in the intake ports is incredible.


Timing chain cover removed.


Heads are off. Notice the burn patter on the pistons.


Spun the motor around and removed the crank craddle and walla we get to see crankshaft and rods.


16 bolts later and the end results.



I am really starting to be impressed with the guys at AMG. The bottom end looked like it had just been assembled. Bearings look new with no wear and the cylinders look brand new. The bottom end is second to none in terms of strength to any motor we have opened.

Next we going to the engineers.

i only see frogs...

Timing chain cover removed.


The cover itself. Real solid pieces.


These 2 pictures are showing that they have been removed by imageshack...



Great work George

Keep it up

[Baracus]

Frogs gone on this page?

[Calla335]

I see all the pics!

[Jakkals323i]

yip they gone

[George Smooth]

Ok will do the rest of the pics.

[moranor@axis]

no more frogs just a few on the 1st page that i saw...
