Let's leave it to the car owners to install of not install these... If anyone bought a kit and feels it's unsafe, feel free to contact me and I'll lowball you for a quick sale, LOL 
I'm not an engineer although I'd really like to think I am... If these REALLY caused premature failure in ANY WAY, SHAPE, OR FORM, there would be overwhelming evidence showing that... We unfortunately are all ASSuming what counterweight this, harmonic that, and pulling quotes from the Internet and other forums, which can be the LEAST reliable sources of information...
I DO believe and will state again that shítty install causes pulley issues...
I have a Stillen 20% under drive, would I ever take it off? No, will I continue to install one on every car I own? Yes
Hell, I already have a kit for the Maxima I am forcing my dad to buy, lol
Some of us (7AT) don't have a flywheel, and it's also about removing rotational mass, so the car feels peppier. I try to explain it as, "Have you ever driven a car with a lightweight flywheel? Well this is like 10% as much as that does"
If it makes díck difference, I'll ask my best friend's dad who IS an engine engineer (for Cummins diesel though) if he has any input |
well im just giving OP my opinion on the mod, from what i have read on mustang forums, LS1tech, honda forums, other nissan forums, ect. that underdrive pulleys are generally not worth the money in the same sense that headers are not worth the money and i have read about pulley attributed damage(whether or not it was cause of bad installation is a whole other story) and honestly it doesnt seem like a risk
I would be willing to take for just 2-3whp in first gear(again from what i have read whether its Z related or other car related)
if someone likes swapping pulleys on their vehicle, then more power to them, if OP decides to put an underdrive pulley on his car, then more power to them
i personally wouldnt swap pulleys on my car, but thats just my $0.02
