hi guys.
Finaly I installed my MD 5/16" spacer on my car today.
everything was fine, but There was one problem with 6 center bolts.
I did the test drive after the installation. and I checked 6 center bolts(because someone had a problem with 6 center bolts.) after test drive, doesn't stay torqued with 60 in-lbs. So I re-torqued with 100 in-lbs 6 center bolts. would be ok with 100 in-lbs?

 

I had to retorqued the said center bolts 4 times to 60 inch-lbs. until they all held. This was over a period of some 3 months, as I checked from time to time. I would not torque the center bolts much more than you have. Wait a week and see if they hold at 60 inch-lbs. I think they will.

 

Thank you andy.
But I already re-torqued 100 in-lbs........ Is it okay? What I worried is inside of plaum 6 plastic internal supports(I wish it stay ok. ;(
And I won't torque 100 in-lbs anymore as you said.

 

You should be fine. I would have initially been a bit more concerned about breaking a bolt ot two. Some members have reported snapping bolts, due to over torquing. However, it appears that you survived that peril.

I would simply sit back and enjoy your handy work and check the bolts at 60 inch-lbs. in about a weeks time. Enjoy your new spacer.

 

you knwo what's weird; i know a lot of paper say their center bolts become untorqued over time, but i checked them again for the 2nd time in 3months (since i had plenum stuff installed) and mine havn't budged at all.....weird?

 

sup atlantic~

Give me your plenum and spacer... LoL

 

Noooo, 100 in/lbs is too much for the center bolts! Read this thread, especially from Hydrozine which is Tony of Motordyne Engineering.

Center bolts shouldn't go over 75 in/lbs...

 

I think Hydrazine is right in that the plastic spacers heat cycle and after a while they stop cycling which allows you to get the bolts perfectly torqued. Mine are still at 75 in/lbs and holding fine. At first I was using 60 in/lbs and having to retorque every couple of days. I kicked up the torque a bit and everything was fine.

 

I personally think 100 is a bit to much. 70-80 would have been fine.

 

Would Locktite hold those center bolts and keep them torqued while the plastic spacers heat cycle?
