It still amazes me that whilst 500+bhp seems more normal, that people do not seem (who havent gone through the stress of either sorting these engines or parting with the money) to realise that whilst BIG bhp figures are more attainable nowadays, these cars need a bit more than an oil change every 12 months and do need looking at in between!

Anything 500+ on a 2ltr is pushing the boundaries of reliability and life expectancy.... regardless of what you do in my eyes. Something I am sure people like Martin are all too aware of.

Like you say Martin...... you could of had a skip full of bits!

It takes balls to take these kinds of vehicles on track for a beating..... especially people like me that only turn up to track events with a screwdriver and insulation tape!!

 

I would be defo on the phone to the supplier asking if it was made of billet chocolate surely it shouldnt break so easily

 

I'm sure Martins got it in had lads!

 

Franco, how come you changed your name again?

cos you smell like a yeti?



did you get that CD?

 

Long story.............. But think of it like a caterpillar bursting out of its cocoon as a beautiful butterfly!

Sorry mate, havent been home for a couple of days. Will check tonight!

 

from the looks of that, now i've seen it again, it looks like the woodruft key has probably saved the day because that seems to be the bit that's held it together

on the other hand, unless someone has unbolted the bolt, it would have only been a short while for it to have worked itself loose

and, seeing as i don't know who built the engine, i'm not going to comment on the build as it seems fairly obvious the bit that's broke wasn't the bolt

 

Well If it was the engine builder then a few of us could be well fucked with our engines!

 

Yeti Racing

was it you





































and is that why you've been away for a while

 

WFT! Its Franco you gibbon!















And if I'd built that engine.............Well lets say it'll be safe to say that it wouldnt of made it off the engine stand before failing!

 

of the pink dildo waving grease moneky picture fame
















note to self, don't buy an engine built by franco

 

Dojj thats not a woodruff key you plank its a part of the material itself. However you are right in saying it has stopped the pulley from coming off....as it looks to me to have kept it on the last thread of the bolt (i.e. the tab has stopped it undoing itself off of the last bit of bolt)

Martin
Me and my workmates (material engineers and a few metallurgists) have looked closely at them pictures and we've all come to a rough conclusion that the failure started within the the bolt hole (at end of the projecting tip left on the crank) and has failed upwards in a V shape towards the end of the bolt to the area where the stress is (if you imagine where the crank exits the block to be a pivot point) which happens to be where the bolt ends and looks to be the area in the vicintiy with the least ammoutn of surface area.

I cannot without looking at it though say 100% what caused the initial failure from within the threaded hole area....If I had to hedge a bet it'd be from an inclusion within the material or a lamination or contamination of the metal.

If you dont mind i'd like to have a look and see it close up...i'm in Birmingham and can give you answers. Then you will have ammunition to hit the manufacturer with for a refund/replacement.

I have the afternoon off friday so can nip in then if its convenient.

Dan

 

By all means take a look See you Friday!

 

Bought a new crank from another manufacturer, it landed today.

 

dke ???

 

you dont hang about do you martin!

 

that's what i was saying
because the break has happened at the woodruft key point, the key has probably prevented more damage by keeping both bits together when the break occoured

 

The hanging about bit is the worst part of mechanical failures, once you get that new replacement part - its all fun fun again ....

until that credit card statement arrives....

By then its all sorted and your having fun again.

Good to see cranks arrived and hope all goes well with re-building.



Hope a outcome comes of a warrenty claim too

 

fitted yet

sad news, but glad it had a limiting effect and didn't total the engine

when's the next outting?

 

talk about dont hang about

 

Now taken over by Arrow.

Wassap fatso....long time no speak!!

 

Sadly all the bottom end now needs re-balancing, not too expensive but it will slow me down by a couple of days.... Safe to say it will be sorted by this time next week though..

 

Nice!


By the way....read your pm

 

great news

 

Hi Martin,

Just wanted to say publicly that it was superb to have you enter the Final on Sunday and a real buzz to see you circulating, albeit cut short by the crank problem before you really got to stretch your legs.

Fair to say for all concerned it was relief that what happened never caused more damage and that the repair seems well in hand.

Time Attack is not all about ultimate big turbo stupidly mental power, contrary to popular belief, and for this reason I believe a well prepared, set up and driven Cossie can genuinely battle for honours in Pro.

We look forward to seeing you back in Time Attack 08 Martin and getting stuck in amongst the fray.

Keep well,

Glen

 

Cheers Glen 08 is a must

 

@ martoon with his new crank casually lying
on the floor in the work shop with hundreds of other
discarded bolts etc. 10 a penny eh
if that were mine it wound be on a red carpet for a pic
then quickly cocooned in the thickest bubble wrap ever.

 

jesus that was lucky!

 

Fair fucking play in terms of the schedule to get it fixed, you sir, are a legend
