Lug nut torque ?

[kingsburgphil]

This is kinda embarrassing, but what is the correct lug nut torque for ERCO's with clean & dry 14 mm studs, 19 mm steel nuts and radiused alloy "washers".

While torquing the nuts the washers don't "like" anything over 70 ft. lbs. (Snap On & Proto torque wrench's). I've been away from VW's for far too long (blame GM) so I could use a bit of professional advice.

ft. lbs, or Nm, are ok.

P. S.   Anyone have any input on using 911 alloy lug nuts?  How about trimming the ends open per NHRA specs?

I never used a torque wrench for mine, I just did them up until the felt tight, if that makes any sense. I used the regular closed end nuts they were supplied with, and had to remove one every now and again to prove to the scrutineer that the stud extended far enough into the closed nut.
As far as the 911 alloy nuts, I seem to remember reading that it's a bad idea to open the ends up because of it compromising their strength due to the material, but I might be wrong!

did mine 85nm if you torq more the alu washer will crack.

Phil,
Using the porsche nuts with Erco washers on ercos I torque to 90ft/lbs,never had an issue with washers cracking.I use the nuts with the ends enclosed still,not had a problem at tech with it like this

cheers richie

Thanks guys,  I'll try again to torque the steel nuts to something approaching 90 ft/lbs. The last time, the nuts felt like they were "going thru" the
washers, and common sense said "stop".

Regarding the Porsche lug nuts, I seen quite a few "twisted" nuts without them being modified. If tech will accept a closed end nut.....more power to us.

Thanks again for your input

Phil, I think the rule for the closed nuts is that the stud must protrude into the nut AT LEAST one diameter of the stud. So a 12mm dia. stud needs to have at least 12mm of thread in the nut. Common sense says that you don't want so much sticking out that the nut bottoms out either though.
I'll check the rule book later if I can - it'll be something similar for UK and US I would think.

Just bought this Erco wheels, the race version.
Do someone know were i can find bolts and washers?

Torque specs for various fasteners varies depending on material, but you can find a reference table for steel bolt torque specifications at http://www.engineershandbook.com/Tables/torque.htm (standard) and http://www.engineershandbook.com/Tables/torque1.htm (metric).

Not sure about the Porsche alloy nuts specifically, but I do know that the open ended aluminum lug nuts that Mark Williams makes are NHRA legal. I have a set, and believe that the wall thickness is much greater than the alloy Porsche nuts that I've seen.

I purchased a nice set from David Cornatzer - http://www.thesamba.com/vw/classifieds/detail.php?id=536285

I needed to to test drive the cantankerous beast last week, so first I set "ol" reliable Snap On torque wrench to 90 lbs. All twenty lug nuts "clicked", If
they're happy, I'm happy.

BTW, the barely drivable beast is now just a big pussycat, changing the clutch disc,throttle linkage adding syncro's and losing the spool has made the car quite drivable.

Who say's an Fk 89, 51.5's and ported Comp E's won't work on the street ?......it's just my cup o' tea, but not necessarily anyone else's 
Next up is putting the "baby on the bottle".

Thanks again for the quality input
