Prima racing crank pulley

[mikekean]

Thinking of getting one of there Aluminium crank pulleys while i have the engine out of the cup car. Does anyone have any experiance of them?

Ive noticed the standard one has a rubber damper in it, but the prima one doesnt. Is this actually needed? i dont want to buy one then have issues further down the line.

Prima are a good engineering company.. got some old school boys that work there, I've never had a problem with them :)

I would always run a damper if the OEM specified it.

I've just ordered my genuine crank pully,the rubber part is a Vibration damper
it reduces transmitted engine noise.
Solid one who knows wot would happen.

Could you think of any side affects of not having the damper?

 

[Icarus]

Crank failure is the main side effect. Certainly K20 and 2ZZ engines are extremely sensitive to changes in the crank dampers effectivness.

Ok ill give it a miss then. The billet steel flywheel i just bought for it wont have a negative effect will it?
