    New eg33 billet stroker crank shaft group buy

    Ok as most know iv been in talks with arrow cranks about a possible group but and due to costs this isn't the best time for most and the fact that another member has approached them and there now quoting 3600+vat this just isn't a option for myself any more

    I have now approached a local company who have been specialises in crankshaft production for over 30years with many prestige customers from the like sod Aston Martin rolls Royce and Bugatti aswell as the making the crank shaft for many hi revving zetec and bda engines and the famous 6r4 metro rally cars many years ago aswell as many currant rally car teams and suppliers for Honda ford BMW subaru and Mitsubishi aswell

    Also aswell as the standard reproduction crank shafts and full performance billet crankshafts they can make con rods to spec ad many other parts aswell which I'm in talks for other products also as we speak

    Iv payed them a visit today to view and get a feeler for them after a good chat about our needs and a tour around there work shops and showing me the 6millon pounds worth of Cnc machines and all the machines needed for the process iv pretty much been blown away

    This is a full cad design crank shaft that iv been assured the quality of the product and finished aswell the material and machine cannot be matched by any other company in the uk at present in there words you will not break this which looking at some of there bespoke customers crankshafts I take that as gospel

    We finally got down to the serious talks of money and what a pleasant suprises he has offered them in batches of 5 crankshafts for 1750 each all in this is for a 1 piece 79mm cross drilled nitrided crank shaft fully dynamically balanced with knife edging if preffered at a turn around of 6weeks for the batch

    For the ones wanting that bit extra he has also offered a full super finish/micro polishing on the crankshaft at 120 extra per crankshaft

    I'm I the process of getting my own crankshaft made were just waiting for my standard crank shaft to take them that for the exact measurements then the process will begin once the first one is done the others would take half the time only to reproduce

    I know this is a big part for alot of high powered engines with alot of money spent at them and this isn't a proven product at all but saying that the arrow crankshafts wasnt proven for this engine before andy tried it at a great cost iv ordered my own and am happy to run this and I'm positive there be no issues at all so now here the questions who else is up for one ??

    On a side note I'm also in the process of looking at getting the billet cams made by these also aswell as a correct fitting 14mm head stud conversion for this particular engine aswell as the likely hood of con rods I beam and h beam again all built to spec to take what ever is chucked at them

    Please if your interested post you thoughts and views il try to get any info you need and answers to any questions you have thank you

    Well the stories and the samples they have of arrow crank shaft and rods that have failed at there site I wouldn't personally use a arrow crank now these are customers crank shafts that have failed and they have had to make them a crank shaft up to replace the arrow one that simple wasnt up to the job also it may not be proven in this engine but one of there crank shafts is well proven I a 2000bhp+ Vauxhall victor there regularly does sub 7 qtr miles

    What makes arrow any better if they haven't got the same state of the art equipment are a smaller younger company and use lesser quality material with less process and options???

    It would be interesting to hear Arrows view of the company you are in discussion with, just to balance things!

    Also the 2000bhp car is of little consequence when you consider thats from an 8 ltr motor and it only runs 7 seconds at a time. Thats the same specific output as a 2.0 making 500bhp.

    Not saying there's anything wrong with their cranks but then the Gobstopper and the Banana have given a 'proper pasting' to Arrow cranks without issue so I think you are taking it a bit far saying you would never use one in a road car!

    Not saying I wouldn't use one never is a strong word biit the 2000bhp Vauxhall is full road legal and I'm sure it's 6 sections and not 7 but what's a second or so

    Arrow are fully aware of the company that's no secrete and not knocking them but I carnt justify paying a nearly qouted 3600+vat that they quoted another member on here yesterday a price should be a price

    I'm not asking anyone to side with ether ether way I'm ordering this crank im sure if I prove it's power capability that there be many people asking for them the same with yours andy but if everything I'm saying is correct and the machining and the material and the service is better it goes to show how much arrow are putting on each crankshaft

    They have told me all the specs and like a clown I have lost the list down il be seeing a email to get them all but he has said they can use any material you like basically but he has said one that for the life of me I carnt think which he says is the top grade

    In your opinion andy if the material is matched or improved the machine work again matched or improved also the added cross drilled/micro polishing/knife edging and nitrided and dynamically balanced can you honestly say the price different isn't worth the switch over??im not sure what the arrow offer in terms of extra or extra charges do they have crossed driller and nitrided and knife edged as standard order andy??

    Arrow are crossdrilled, or rather low pressure oiling drilled and are also nitrided 4340.

    Yes its worth a trial Matty for sure and its a good price, particularly for a one-off.

    The journals and thrusts are micro polished as standard, knife edging is not much (if any) advantage on Subaru cranks as the webs are already so thin (as dictated by design constraints) that the reduction in windage is negligable.

    It sounds promising Matt, but cheap(er) must not stand in the way for quality, i'm curious to hear if its 4340 or EN40B. Would you be so kind and tell the name of this company? I'm just curious to see what there name does when I google

    Might be intressted in one Matty

    frank its allens crankshaft i have no problem with you googling them as i have been promised sole rights for the sale of these from my suplier it saves him dealing with 20 customers when he can dealo with just one and cheaper the reason for this is twice as many cnc machines running rather than a few working flat out he turns over more cranks than arrow also

    the material i will comfirm but as mentioned he can make in any material you like so what ever you preffer

    Tnnx Matt,
    It's indeed a "bit" strange that the price goes up and down like the petrol prices....
    Did a quick search, and I'm getting more intressted...
    Is the price (1750) incl vat? would make it even more intressting

    hi frank hope you found good results because thats all i have done and yes the iup and down price is annoying its not like there low then going high and going even higher thats good money to spend else where for me

    and yes 1750 is the all in price frank that is the standard finish item its 1870 for the complete micro polished finishing if you wanted tat but its optional

    what kind of power are you looking to run frank as looking at your thread and car so far im thinking alot more than anyone has so far also with your trans and monster rear tyres the arrow crankshaft isnt proven for this sub 6 second run or power yet the chances of that failing is always a possiblity at a much greater cost dont you agree??

    You have a point there, but I'm reading in your first piece of your thread that says a batch of 5 for 1750,- or do you mean 1750 a piece too?

    Power is nothing without control

    the first order will be bit of a weird one frank he is doing mine for this price i have another member also wanting one making 2 if you want to jump on board thats 3 straight off he will make these for the 1750 or 1870micro polished

    after that and there tested they will be brought in batches of 5 so it will mean me doing orders and ordering 5 at a time to keep the price at this if i have to buy more than 3 myself to make the order up and put them on the self to sell on so be it there will be a surcharge ontop for me doing this then but it saves customers waiting so it all depends how popular they become in the future but at this time 1750 get you a nice brand new crankshaft that should take anything you chuck at it 1870 gets you a ubber slippy nice shiny micro polished one
