maybe there is someone used to sell...


thanks

 

For the power you are aiming to run I would go for a custom crank and rod combo from Farndon made from a stronger billet material with more meat on the webbing to resist flex

 

hello

the engine is ready..I think now the only buy crank......(I can not spend so much money now..there is still much work to car)

 

If you cant wait 12 weeks for farndon to make one go with the Farndon one Burtons have in stock

And dont use Arrow rods

Get Farndon (robson engineering), to supply you direct with some custom / stronger ones

 

I wouldn't be using a used crank, well not in your engine anyway.

Drop Steveboyslim off here a PM regarding the Arrow parts, he can possibly sort you out a better price than retail.

 

I have cosworth rods..

Now I do not want to build a new engine
I just do not want to have it broken thr crank

 

Out of interest whats wrong with the Arrow rods ?

 

I now use using factory crank

 

Two of my close friends have had engine failures with Arrow rods bending, fact

Arrow machine the centre section of the H rod too deep close to the bottom shell area which causes them to bend under high load

Farndon do not machine as deep on their rods due to experience

Farndon rods are heavier but stronger

I have a custom Farndon crank and rods myself and the quality is very good

As for the cranks, Farndon have been making cranks for years, A few years ago a guy called doug kiddie who worked for Farndon set up on his own making cranks.

A few years ago Doug Kiddie sold the outfit to arrow who where a con rod manufacturer to get them into the crank business.

Due to the buy out all the machines were relocated to the arrow factory but rumour has it few of the experienced machinists moved with the equipment.

Thats why in my opinion Arrow have only a handfull of years experience with making cranks.

And also the fact they usually try and charge twice the price of Farndon for them.

Swindon Race Engines have a state of the art machine for making cranks but the price will be high, cosworth has crank making facilities also

 

Suprised to hear that !

It would be interesting to hear who is using either arrow or farndon in powerful engines on here.

I know people who use both arrow and farndon cranks and rods with no troubles at all

 

Both of my mates run Farndon cranks for the last 5 years with circa 800 whp with no issues.

Ian howell used a Doug kiddie crank in his 600bhp plus duratec turbo engine before it split the block but he had to send it back a few times as it didn't fit in his block the first couple of times.

Dont know anyone with an Arrow crank as there too expensive

 

Well here is a Farndon crank it 2 pieces.



I guess everyone gets it wrong, as for price I agree the Farndon is far cheaper.

 

Wasn't that Martin Hadlands crank?

I've seen the same thing happen on a TR6 Farndon crank

The pully bolt was but on with a windy gun which fatigued the nose of the crank

 

That one was Mike Rainbirds and I believe was a material failure, same failure as Martin had though.

I'm sure Mike can clear that up but I was quite shocked when it fell off in my hand.

 

Surprised at that

I'd be interested to know what the underlying cause of the problem was?

 

I also know someone who had a Farndon crank in his race escos and it failed in the same way as above
