What he said .

pee vee

while this is up here.
Are the standard cossie Rods the weak point of the engine?
(or least strong point)

if they are not, what is?


thanks!

Nope, standard pistons are the weak link. Cosworth or other forged ones are required for above 500bhp.

As Gareth and Mike Standard rods are a little heavy to be using much over 8200 rpm but are as strong as old boots

pee vee

brillient thanks Mike!

they made the YB quite well in that respect then!?

Stavros

The YB was made as it was for homologation reasons, GrpA rules at time stated they had to use standard crank and rods, so they had to be able to take 500bhp+ for a full race with no probs, so strong as fuck

Same as why standard RB26 crank and rods are silly strong.

my standard rods and crank have been fine running over 600bhp

however they have now been fired as someting else is getting their job

Ginge !

my cossie bent 3 rods when i stripped the engine down


does that mean i was just unlucky and should stop dropping it to second for quick braking and byuy some bigger brakes then

ive always been told if i wanted to go for 500 or above i need stell crank and rods

so what will a yb crank and rods handle i.e

lightened and balanced
knife edged
tungstun coated

also rods polished and stressed relievd

balanced etc

will they be up to the job for 450 reliable

im using cosworth forged grp a pistons 7.2.1 c/r

Ginge !

kevin forgot to mention there fooking heavy

people only think the cossie rods aint as good as they aint finished all blingy like the farndon jobys

Stavros

det.

piston in cyl moving up while det tries to push the thing down equals bent rods.

esp as in cyl pressure in det is massivley more than normal

Incorrect ignition advance/retard can bend rods!
