Mrev2 and torque wrench...Q's
 

I'm about to install my Mrev2 so I bought a torque wrench in inch/lbs. I read over the instructions (of the torque wrench) and it says that if you add length to the torque wrench, you have to use a formula to find out the new torque setting.

My question is: I'm not adding any length but I am going to add a longer adapter/extention (so it looks like a "L") for the socket. Do I still have to use the formula or is the reading going to be accurate? Maybe Tony can chime in on this.

R u gonna add an extension or a crowsfoot or dogbone? WHY is it even necessary to add anything but a socket?

Just an extention probably, I haven't taken anything out so I'm not sure if an extention is even needed...will just adding a socket be able to reach?

No adjustment needed when using an extension. The important thing is NOT to add an extension to the HANDLE of the torque wrench, and to always hold the handle near the center, as it was designed, or the torque values will be off.

Near the center...meaning as close to the socket as possible? I'm going to re-read that manual...the last thing I need is a snapped bolt in my engine :icon9:

Please read How adaptors affect torque.

Just don't drop it on the ground and reuse it. Just a force of habit for me since I used to work on airplanes. If you do get it re-calibrated.

Hey Bugs!

Its not a description of how to add an extension to your wrench... Its a simple conversion formula for converting foot pound to inch pounds.

This is to help people who have foot pound torque wrenches with an appropriate torque range.

Tony

I meant the instructions that came with the torque wrench...not your MD manual. Hehe, it sounds like I don't need to convert anything as long as I don't increase the length of the torque wrench. So final word, adding an extention, no need to recalculate...adding length, need to recalculate, right?

Without seeing your specific instructions (its probably OK).

Someone never took high school physics :hmmm:

just playing bro ;)

adding a SOCKET extension no problem (you actually lose a tiny bit of torque)

adding a HANDLE extension, alters torque.

Lol...yea physics was hard...thanks, cool..installing mrev2 tomorrow! woot!

...so long as the "extension" isn't, or doesn't include, a swivel (universal) extensionl socket you're OK. Swivel sockets can significantly affect the accuracy of the torque wrench.

Smooth slow movement of the wrench is also important.. as is relieving the pressure on the click-style wrenches when stored.

These may be silly questions, but I am planning on installing the MREV2 and spacer tomorrow, and I'm looking over the instructions along with the service manual.

I assume the differences in torque settings are intentional and required based on this mod, but I'm a bit concerned when I have the car at the dealer for routine maintenance, etc. If I don't inform them of the mod details and the new torque settings, don't I risk them cracking a strut spacer, stripping a plenum bolt, or worse if they use the factory specs?

I also noticed the service manual states most of the numbers in ft-lbs. I have a N-m (ft-lb) torque wrench already but was planning on getting an inch-lb as per the instructions. The service manual also provides torque numbers for the throttle actuator which I'm not sure how I'd measure using an Allen wrench.

Any guidance is appreciated. Thanks

I'm curious...
 

So if I took my car to the dealer for something that might be warranty-related and for something with a possibility of being on or around the intake... I would want to swap back to the stock lower plenum and remove the spacer. Would I need to replace the gaskets or are they re-usable?

I wonder if they'd even notice the lower plenum was different. Maybe taking out the spacer would be enough.

I could see those idiots not wanting to honor a warranty issue with the windshield wipers after noticing a mod on the intake....:icon14:

All the bolts can be tightened to factory spec no problem, but then again, they won't be doing anything to your plenum unless they had a specific need for it to come off.

The gaskets are fully reusable. I reused them countless times during the development phase.

You could take the spacer out if you prefer but its very unlikely they will notice. Particularly if the engine cover is on.

Be careful taking it to the dealer to install. My guess is they will use an impact wrench or some other huge ass wrench to overtighten the bolts. Just like they overtighten everything from lug nuts to oil pan drain bolts.

This is just one of those things, if you want to get it done right, do it yourself (or have an experienced friend install for you, thanks again Tony lol!) :)
