Installing 1000HP ati balancer on RB26. stock crank bolt or ARP version?

[burn4005]

Hi Guys,

I'm going to be installing an ATI 1000hp balancer this weekend on my ~800 flywheel horsepower RB26 has a steel trigger wheel welded to it adding about 600 grams. will torque to 450Nm with oil as per manual, is the OEM nissan crank pulley bolt the correct option for this damper or should I be using an ARP (102-2501) version?

cheers

Oem is fine I believe. Sturdy bit of kit but with an 800 bhp machine with all that work is it not worth putting the ARP one in?

Yea came to that conclusion and ordered one today. Cheers!

I think the arp bolt needs to be torqued to 650nm, is the motor in the car ?

[burn4005]

No, that is not the case. ARP recommended torque is 325-345ft.lb (440-467Nm)
