I have a question bouncing around in my head.
Heres the deal; I have a set of BC Econo Rods w/ ARP 2000 bolts, installed on running motor.
These Rods are rated for 600hp maximum. But, I want to make around 850-900hp 10,000rpm. Would it be a bad idea to upgrade to the same torque spec ARP 625+ Bolt, being as the engine has been ran about 2,000miles?
The Bolt upgrade would be with the Engine installed in the car.
Thanks in advance for any advice given.

 

just get new beefier rods

 

You're planning on making 850hp, why does it seem silly that you're asking about what kind of bolts you should use?

 

I may just do that? I really don't like the idea of removing and re-installing different bolts on a used engine. They rate them Rods at 300hp each "when using the ARP 625+ Bolt". I know the Econo's w/ ARP2000 have been used on 800hp engines but, I don't wanna blow haha.
