Drivers side tensioner installed wrong from Ford?

[Mod Mustang Racing]

Just wanted to spend a moment and chime in on this, as most of you have already figured out the tensioner being inverted is the "correct" way to tension a chain when it comes to a mechanical timing system. Is it needed for a stock car? - NO. But the more you modify the car with Boost, aftermarket cams, aftermarket springs etc more load is placed on the chain and tensioner, turning what ford calls acceptable variances into what any aftermarket engine builder would call unacceptable. Certainly no conspiracy theory lol. Ford did this on the last generation DOHC and Roush originally designed the fix (inverting the tensioner). Bottom line, if you want it to be right, this is how you do it. The side affects of not doing it are simply timing variations on the drivers bank - not the end of the world by any means but something that should be corrected for anyone with aftermarket cams, springs etc. And @ just $59.99 why take a chance!!

Thanks for the informative response, I know understand. The first time reading your explanation had me thinking otherwise. I'll edit some of my strong opinion earlier in this thread as they are not warranted with what you just explained.

Personally if I was taking the cover off my car to upgrade the OPG, and sprockets, this is a no brainer. Chains/belts should always be tensioned on the proper side.

No problem and our pleasure! :cheers:

Under heavy acceleration when you are accelerating the cam rpm, does the "wrong" side end up with untensioned slack on the bottom?
This could be really bad in that you be shock loading the timing chain and crank sprocket real bad coming in and out of throttle/load.

yes, this is the way they come from the factory, the MMR bracket fixes this.
