Hello,Regarding the timing-chain, what is the “improvement” there? Tensioner?
they are offering "modified tensioners" via AR (which i orderd for my car to be fitted in production) besides several other further "upgrades" (as i.e. one-mass/lightened flywheel, dry sump, big brakes,...)
I emailed AR 3 times when I had my 3.7 asking if the tensioners could be modified as the engine sounded like a bag of spanners. I didn't receive a single reply. Really not impressed.
Noble, who use these engines in racing, strip out the VVT tech altogether and also modify tensioners.
