max hp stock forged counterweighted crank?

[mikaelh]

Hi
i got an original german made crankshaft wich is forged and welded counterweight on and wonder how much it it can handle?
69 mm stroke its made by bug pack 23 years ago.

I have used a stock non counterweighted crank in a 250 hp turbocharged engine with no problems.

2-4 hundred? Doesen't really matter, as long as it's more than all the other parts
At some level of HP and rpm the flywheel will come of, does that count?

seems i be on safe side=) i plan to rebuild a low hp street engine for my 1303s.
i will use my as21 case build a 1915 cc and use this crank and rebuilt original connecting rods and cb 44 heads.
winter and darkness come here now so now its more time to spend in my workshop.

Hej mikaelh (Hello mikaelh)
Another swede here.
I think you are safe with the welded counterweights on the forged crank.
Make sure to get the crank + flywheel + pulley balanced at a local engine shop.

I did that with my 2007 I finished late this summer, and there is almost no vibrations.
I also weighted the pistons and conrods to differ 0,7gr lightest/heaviest.

Going from a tired abused 1600 to a fresh 2007 is quite the experience.....

IMHO if you want to know then you want hp. so sell it and get a 82-86 stroke crank that will make the power.unless your going to force feed it then it will also make power. but then I would still go with a new crank. but thets me... Im kinda stupid that way..
