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

Great saving but just not proven to invest thousands in a engine, however you don't know until you try lol

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???

13th November 2012, 16:48
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!

mattybr5
13th November 2012, 17:11
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

Andy.F
13th November 2012, 17:21
Are they not using 4340 for their cranks?

mattybr5
13th November 2012, 17:26
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??

Ren
13th November 2012, 17:47
Allens / Laystall at a guess, probably EN40B

Andy.F
13th November 2012, 18:16
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.

mattybr5
13th November 2012, 18:20
ok andy thats fair enough i take it you didnt bother with the micro polishing or knife edgeing?

well i didnt want to cause a disbute and was unprofessionalto have put arrow down as you say they do make great products and lets hope they continue to do so but ether way im ordering one for my self and when i prove it can take what i can chuck at it like you have then im sure there be more to order then anyone also wanting to take me up on this then your welcome im not making anything on them i simple want a good deal as you all do

Andy.F
13th November 2012, 18:29
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

mattybr5
13th November 2012, 19:53
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

mattybr5
13th November 2012, 20:04
sorry frank on another note about price a member on here who cannot wait for the arrow crankshaft group buy messaged arow him self they have now qouted him 3600+vat for one crankshaft i got qouted 2975+vat andy f payed 2800+vat this just shows how much profit they are willing to put on each crankshaft in my eyes upping the price so much is totally out of line i cannot justify spending that amount im sure most others wont ether

PS-06
13th November 2012, 20:24
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 ;)

mattybr5
13th November 2012, 20:29
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??

PS-06
13th November 2012, 21:16
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 ;)

mattybr5
13th November 2012, 21:22
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 :)

14th November 2012, 00:45
I'm undecided on this at present

mattybr5
14th November 2012, 18:28
well the order for 2 shafts have gone in hopefully in a about 4/6 weeks we will have a finished product to show off and hopefully i can test them and im sure if they turn out as good as they promised there be a few more wanting these then so there no push to order one at all i will say try and speak to russell direct at arrow if you go for one of there as the prices vairy so much you want to know a firm price fella

also on another note its not just 6 cylinder cranks he can do he can also do the 75mm or 79 or 83mm stroke crankshafts for the 4 cylinder ej range engines also again at very good prices

No dates fella still alot to do before they get fully tested by all parties already on board when they are on the shelf the initial price will be altered also accordingly as it's taking alot if time and effort from all parties to get the product sorted so this will be taken into account for the rrp price fella

I thought you just give them a crank and they make it?

Whats to be sorted other than the buyers giving them some 1000+bhp use to prove them?

mattybr5
25th November 2012, 21:09
P1 te few people who have come on board with this now are gettig them at 1750 yes fella I know it was a big ask bit the ones have see te potential in them and want to save the money so one these are made and tested all at the 3 people own money time to test and also at a risk of there new engines to a degree then after that no there will be a increase in the price they won't be no where near the price of precision but why should we go to all this trouble for nothing??we are given time and effort so the price will be upped for the people time it takes for this to come off

Andy I don't get your post??you don't want in on this that which is fine but unlike you we haven't been given the drawings that pat has done some time ago to copy the crank shaft is being designed not copied some changes are going to be made to hopefully have a better product I don't get what your post has any relevance ??

Andy.F
25th November 2012, 21:22
I was just going from your first post when you said you just need to give them a std crank and then 4 weeks later you get a 79mm one for 1750 all in including vat. Are you saying thats not the case now that they have had a look at it?

I have customers interested in the product at that price but is the price going to increase now someone has taken a commercial interest?

25th November 2012, 21:30
It's a lottery with the price IMO maybe closer to arrow pricing by the end of all this ?

I just want a crank for my engine lol

mattybr5
25th November 2012, 21:30
Yes andy i know your interested party in the crankshaft we ave spoken already and Come on andy I know you didn't take that I give them a crank and it gets coped to serious they wanted a standard crankshaft for a reference it's being completely remade to what they think is needed a full cad design is being drew up its not a back street place that's doing its being done te correct way and now I have some extra help were looking to get the best possible product we can as for the price iv already taken alot of time and effort as have the other members who are contributing to this why should we able charge what we like??you do with your cams you put in all the hard work I wouldn't expect you to sell them and not have some reward for all your time and effort??ether way this crank will be nearly half the price of arrows cranks and available on the shell at some point the Price will be set and not changed depending on what mood I'm in I cannot fairer than that

mattybr5
25th November 2012, 21:32
P1 sorry I don't know your name no it's not going to be anywhere near the price of arrow crank shaft I'm pretty shocked by there prices I wouldn't go charging that price which is just greedy in my eyes the price isn't going to change to much but my time and also money aswell as the other parties who are in on this to give you this product are expecting a little something back you don't go telling rcm that if they have a product out they have designed and taken all the time and effort that you think they should sell it at cost price and they not make a penny on it?

Andy.F
25th November 2012, 21:48
unlike you we haven't been given the drawings that pat has done some time ago to copy

I don't know what you are on about? Pat had the first crank made many years ago which he actually gave to me to run in my car, subject to me replacing it. I certainly never asked for and wasn't given any drawings to copy?
I simply bought a crankshaft from Arrow to a design they have on file.



why should we able charge what we like??you do with your cams you put in all the hard work I wouldn't expect you to sell them and not have some reward for all your time and effort??

So, its not you that has been asking around if anyone has a set of my billet cams you can copy ? Straight answer please.

mattybr5
25th November 2012, 21:55
Andy I speak to you about your camshafts and no one else what we discuss via pm stays between us I came to you first to see if you would lien to try a set you didn't that's fair enough end of that I haven't asked anyone for your camshafts at all I wouldn't even know anyone else running a set apart from your self

And as for your crank shaft it the same thing you have a crankshaft that's been designed already which for you worked out great I and most don't have that option as from what I gather arrow cannot sell that crankshaft as its pats design??unless they change something on that crankshaft I don't think they should sell it unless pay gives the go ahead??arrow also asked for a standard crankshaft they can go off when I was in discussion with them so I take it they don't have the design on file now or they want to change the design or something

25th November 2012, 22:04

25th November 2012, 22:18
I've no idea if there are currently any issues buying a 79mm EG33 crank from Arrow without Pats authority. I went via Pat, maybe thats why I didn't have an issue.

Regards cams, I will be selling my current set shortly due to moving onwards and upwards with futher developments. Thats the problem when people copy stuff, it means they are always one step behind....

Standard crank seems to work ok for the Rigolli boys! Although I do believe they have had one let go but at that power its no surprise really.

mattybr5
25th November 2012, 22:26
Yes I'm glad to hear your constantly pushing the bonfires and also trying new parts and I'm site if your new cams work as good as the last ones everyone will want these aswell andy I didn't start this thread for a argument a discussion yes but I'm not the one to sit there and argue with people iv away come to you first with any ideas you said no to re doing your cams over here which works for you I'm happy for you mate who ever has said I'm after a set of your cams if that what they said I don't know if they got the wrong end of the stick or something the only reason I want your cams is to fit them and use them which you already know that :)

Standard crankshaft I'm looking forward to Simon pushing it on his new turbo set up it like you said there nothing wrong with them so I can gather

As for arrow I don't know the full story but if there is a problem with using pats design it's gonna cause more hassle getting one from them it may even increase the price if there redesigning it again maybe someone can shed some light on the matter

Quick update iv been to see the manufacturer today for a update the crankshaft design is complete and ready to start machining the rough cut crankshafts that will be ready by the end if the week.

At that point il be returning for a update and a look over everything then it be off for the final finishing..at the rate it's goin the first three crank shafts that have been ordered will be fully finished and ready to go out te end if January and orders after that will take roughly 3 to 4 weeks only now all the design has been complete ect

Just gone over a few details with him the basic specs are

En40b nitrided billet steel
79mm throw
Center thrust position
Cross drilled oil feed
Nitrided
Dynamic balanced
Knife edged if desired
Micro polished finish optional at 100

There are a few trade secrets he has added in the design but that isn't to be dosclosed but will all benifit the crankshaft



Iv also got the prices for the 4 cylinder billet crankshafts he also does and te price for these are 1350 per single or 1150 if we canget a order of 5 together

these are again full billet nitrided crank shafts a quick spec again is

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

Are the standard OEM crankshaft shortcomings similar to those of the EJs?

I suspect you can't actually order an Arrow Crank (or DK as it was) without going via Pat as I can confirm it was designed for him as I have seen and possibly actually still have the drawings, and if I did have them still they aren't leaving my computer!

p1 we have ordered the amount needed 3 orders was placed 3 cranks have been made. you had your chance to order one of these at the start fella you cannot jump on at the end and expect us to order more as people please this has been 6 weeks in the making everyone had there chance the 2 other members who was in from the start have there cranks nearly finished now...were not going to carry on selling these until there fitted and tested it would be foolish to sell a untested product as a main stream part

also at close to 1500 per crank shaft i wasnt going to order more than was taken it would be stupid to have such a amount of untested crankshafts that may or may not sell sitting on the shelf..im hoping when we can try and test the crankshafts then if there is enough interest we may do a group buy of may be 5 at a time but we will have to see cheers

24th January 2013, 17:34
the prices was added on the first thread for the first people who wanted to order the crankshafts 1750 fella its on the first post if you read it again..this is a price for the people who have ordered the crankshaft which fair play to them is a bit of risk for a un tested crankshaft but the quality and fitment of the crankshaft will be perfect the material used your not gonna get any better really specially for the price but they have come forward and said yes we haveone at a very small risk

if and when we get them tested and prove there more than up to the job and were happy to sell them there be around 1850-1950 it all depends if we can get the right number so still ahve the price of arrows crankshaft but not as cheap as the first 3 fella i did explain all this to you on prevous replies you had posted

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

Iv also got the prices for the 4 cylinder billet crankshafts he also does and te price for these are 1350 per single or 1150 if we canget a order of 5 together

these are again full billet nitrided crank shafts a quick spec again is

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?

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

That's a clever idea ref the oiling - good job to all involved

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:)
