    Lug Nut Torque

    Has anyone ever asked the SRT engineers exactly what the material spec is on stock lugs? Specifically the Sy (yield strength) and Sut (ultimate tensile strength) or Sp (proof strength)? I'll try to find out then do some fancy engineering calcs to try and determine at what torque damage is...

    Lug Nut Torque

    Mr. Mom The Milwaukee tool video clip is a hoot! Thanks for sharing... Keep them Milwaukee tools out of the hands of the service techs working on our Vipers! They're for "professional use only"!

    Lug Nut Torque

    Since I was venting, I think my question got obscured. Here it is again... At what torque is the bolt strain high enough to damage the studs or the rotors?

    Lug Nut Torque

    I can't seem to find threads dealing with damage due to over-torquing. Would appreciate inputs here. Dealer went crazy with impact wrench, I guess... go the car home and checked the torque - only to find removal torque was 142-14 lb.ft. They just serviced the front end and when I asked the...

    Going from stock ZP tires on 2006 SRT/10 to PS2's, what should new setup be to adjust for the softer tire? It was suggested to use the 2008 setup adjusting Front Caster from 6.00 to 7.00, camber from -0.25 to -1.40, and Rear camber from -0.65 to -1.15 (all else remaining the same). Question is...

    zMAX seems to be advertizing like crazy. When Caroll Shelby stands behind it you almost think there might be something to it. Would you recommend for or against putting zMAX into a Viper engine? Why or why not?

    PS2: 2008 setup on pre-2008's

    Well, some interesting research... I got the 2006 and 2008 alignment specs from the Dodge dealer and they were exactly THE SAME!!! This cannot be so... Then I got word back from Conner Ave. - Lo and Behold, they are not the same... the 2008 specs have changed to increase the caster and...

    PS2: 2008 setup on pre-2008's

    Ignore my last comment - I was still sleeping... Duh! Any dealer who doesn't know how to align for negative camber shouldn't be servicing my Viper!!! MM...

    PS2: 2008 setup on pre-2008's

    mjorgensen thanks, this makes sense. I suspected that the setup change was related to the softer tires. Couple of questions: 1. What is the stock camber setting? 2. Is there a Bulletin to identify the setup process that I can point our friends at the Dodge dealer to? Thanks again. MM...

    PS2: 2008 setup on pre-2008's

    We were walking by the suspension setup jig at the time of the discussion. You may be right, but I suspect there was something more to it. I've got an email in to the Assembly Lead at the factory who has helped me in the past - I'll see what he comes up with as well. MM...

    PS2: 2008 setup on pre-2008's

    At Conner Ave. a few weeks back I was told that I should get a "2008 front end setup" on my 2006 SRT/10 when I replace the run-craps with PS2's. I didn't have the presence of mind at the time to have him elaborate, but I suspect this is a suspension setting that optimizes the characteristics...

    Stock TPMS - are they wheel specific?

    2006 SRT/10: I removed my TPMS sensors to have my wheels re-finished. I numbered the sensors/wheels to be sure they go back on the same wheels. But does this matter? Are the sensors wheel specific? Does anyone know how the system works... I mean, does a module talk to each wheel by...

    Just installed my Corsa.

    I just put Corsa's and K&N Aircharge on my '06. I talked with Jason Heffner (Heffner Performance) here in Sarasota and he said no problem with the mix. The stock system doesn't use a typical mass airflow sensor, rather a fuel air delivery system that adjusts fuel supply by up to 33.6%. He...

    2006 Corsa/K&N Installed - ECM required?

    Hi Juli Just thought I'd let you know that the Admin got me all set up on the site. Thanks so much for your suggestion. Also, I contacted Heffner about the ECN question. He gave me a really technical answer, but the short of it is that the Viper does not use a typical mass airflow...

    2006 Corsa/K&N Installed - ECM required?

    Mike & Juli Thanks for the hints and the quick reply! I've had a little difficulty figuring out this site, like how to show Viper Owner (even though I've registered my VIN in the profile), how to post a pic/epitar etc. I joined the VCA southeast chapter last year and it has been great...

    2006 Corsa/K&N Installed - ECM required?

    I just installed a Corsa Track exhaust using the stock cats, and also installed a K&N Aircharger. With this extra throughput will the car run to lean? Do I need to get the ECM remapped? Thanks. MM...
