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