on ARP2000 rod bolts ? got Manley rods with these bolts and in manual there's only mentioned 30wt oil to use with.
so can I use arp lube and to what specs should I torque bolts in this case ?

yes you can which bolts/rods are they as you need the correct torque ? what size head on the bolt and length of bolt after the shank to the end

 

Yes. Google is your friend

 

not quite sure about bolt lenght, rods are standart 150 mm H beams, do they come with different bolts ?

 

its possible ,what manufaturer ??

 

Dude, nothing changes in reference to torque specs for the bolt-- what ever they reference is the spec--using the lube doesn't chnage that. The lube is designed to give you a more accurate torque thats all.

 

some rod manufacturers spec different torque settings for 30wt and arp lube

 

Manley, it's in first post

 

3/8" bolts I guess ?

If the fastener does not require ARP lube do not use ARP lube. Arp lube is very slippery and has only been tested with their products not stock bolts or any other bolt. You can easily over tighten fasteners that dont require this lube.

 

I'M SORRY BUT THIS IS 100% FALSE

The torque spec is not set for the actual fastener, the torque spec is designed for the joint itself, than you pick a fastener which can actually support the clamp load needed for the joint. The bolt has the same strength, but the joint is what you are clamping.

The lube or any other coatings that come on specialty bolts are there to change the k-factor of the bolt, if you don't know what that is then you know very little about bolted joints. Higher lubricant, less k-factor = higher clamp load for the same amount of torque...That's exactly why the torque load changes with lubrication, the actual clamp load is the same, but the torque applied becomes reduced (with higher lubricity coatings).

Its important to adhere to the torque specs, using say a torque spec for 30wt oil on moly lube can over clamp a joint.
Use the lube and torque spec what ever manufacturer recommends.

FYI
(I've designed multiple joints professionally)

 

there isn't stated torque specs for arp lube in Manley manual http://www.manleyperformance.com/dl/tech/rod-hbeam.pdf
there's only for 30wt oil

so what specs should I torque to with arp lube ?

 

It's commonly 10ft/lbs more with 30wt over ARP lube but I wouldn't go off that, I'd contact Manley.

 

I've got a CRAZY idea..

Use 30WT oil.
