    I was looking for something between the Chinese tat, and Arrow.
    Particularly with the lack of grain structure of EN40B.

    En40b nitrided billet steel
    75mm/79mm throw 83mm throw available at a small extra charge
    Center or rear thrust position available
    Cross drilled oil feed
    Nitrided
    Dynamic balanced
    Knife edged is desired
    Micro polished finish optional at 100

    These can be ordered and ready in 4 weeks time
    Re: oil feed - Can these cranks be specified with "straight through" or alternative options for oiling?

    What about the Manley froged crank ??
    I am running 1 in my car which revs to 8500rpm and makes close to 500hp
    I have had no issues at all since going this way and would highly recomend it for the money

    Thanks for the suggestion. Yes. I'm sure that would be fine, for my purposes - 4340, it's straight through oiling as well.
    But, with import duties, etc it comes out about the same as the EN40B crank above.
    I'd happily use a standard forged crank, but I want to try a non-OEM stroke and a cosworth/arrow oiling system.
    I'm not sure about cross drilling, due to centrifugal issues at higher revs - but I'm not qualified to say whether that's really an issue.

    What oiling set-up did you specify Matt?

    Standard set up - one main feeding two rods



    I don't fancy cross drilling due to centrifugal forces at higher revs.



    What about the straight through design like Cosworth/Arrow?



    Cosworth and Manley

    sorry i hadnt notice the replies on this we originally went for the cross drilled route as its tried and tested but now we have simon osmound on board who has put alot of time and r7 d into this crack shaft to give us the best results its now beed designed with the straight through oil feed as above so with the better materal and higher quality of maching this should be the best crankshaft available

    iv been to see the new desing and old design today and im very happy with the results i have a meeting with simon on thursday as he wasnt there today but il get some more info then but with a few tweaks to the design and nice machine addtions to this desgin and the new oilling system the crank shafts have been delayed a little while but the 3 crankshafts are all machined out and nearly complete there a few prodcedures like the stress releaving and nitrideding and then super finishing to be applied so this will take it into next week for the full final finish of the cranks

    for the 3 we have order the 2 are 100%spoken for but we will have 1 available if anyone is interested at 1750 without the super finish or 1850 with the full super finish if anyone is interested in one

    after these first 3 these wil be available in builk buys of 5 crankshafts at a time if anyone would like one after that we will do small group buys to ge the numbers and the prices to the same as we have qouted above

    quick picture of one of the crankshaft without the final maching/nitrided coating or super finish on the balancer machine while i was there i was happy to hear that no further maching was needed to balance the crank shaft its well within tolence straight out the cnc machine

    Thanks for the update Matt.
    In the side by side view of the cosworth and manley cranks, the straws don't fit into the journals on the cosworth crank - the passageways are a smaller diameter. One for Simon Osman to ponder.

    Cheers andy I think we need to do what you mentioned the other day

    Frank mine hopefully in 1-2months it will be built if all goes to plan another members will be built before mine using one of the other cranks we had done so he be doing the first testing we also looked into upping the crankshaft for more power minded like andy's and yours with aero space material s106 (en40c) this would be over kill for pretty much everyone else and slightly more due to material cost and extra machining needed but I cannot see much else being better suited thats for sale at the moment..excellent news on the pullies then all the bits are coming together il be ready to build very soon so I'm gonna need them

    Are the cranks still getting made nowadays? And how good are they, since a long time has past. Proven for 1000+?
