AP pulleys in limited quantity. Special price for those who would like to do a review for us.

What is the overall feedback from members on these? I am considering getting one if the advertised gains of +10-20hp and +10-15ft/lbs have been verified by members.

something like thatBut yeah it seems like it made a very slight difference, but probably nothing close to the advertised gains
most likely closer to the sub 10hp range, than anywhere near the teens.That being said...even if it does manage to free up 10hp...for the price, it's actually a very good mod. But there aren't enough people that have it for me to personally make the purchase just yet. That and the whole undampened crank pulley debate that will always rage on.

As long as you're looking to damage your engine with this bad idea, you might as well also run without air filters for another few extra hp because I guess that's all that matters

Yes, I have it and have had no issues. It will pleasure your butt dyno but in hindsight I wish I went with other mods first like headers and suspension.

I was just about to this this thread too, glad you did it first. Will wait for the feedback too. I can't find the pully on their website to sell.. Anyone has the link?

Here is a question for AgencyPower/Vivid....
If I buy this pulley, Dyno the car before and after and this pulley makes no power like you have claimed... What happens with the $600? offer a refund policy or..?
Its like Carbonio air boxes spent a lot of $$ and got 0 gains before and after after they claimed 20hp.

I would dyno this but I don't want to risk potential damage down the road.there is a reason mb used a balanced harmonic pulley and the weight and everything went into designing the m156.
I have a p31 with lighter internals and want to see more long term testing before being the giunny pig.i also have a 7500rpm red line on my car and that will always be in the back of my mind every time I get on it hard.
now if you guys make a pulley kit to offset the stock main pulley with a water pump,power steering and alternator pulley I would definitely go for that over the crank pulley.

I've gone about 40k miles without any issues. Haven't heard from anyone else that had any issues with this pulley either. Installing was a pain though, had to remove my radiator so we cold get an impact gun to get the bolt out. Thing didn't budge with a cheater bar.

It's crazy to think you would pick up 10 hp from this. Going from a 40+ lb dual mass flywheel to a 12 lb flywheel doesn't even gain you 10 hp (yes I know the C63 doesn't have a flywheel). Saving 1.3 lbs does?!

This is made from the same magic that has brought us air intake spacers and Boostane, duuuuh. Don't question why or how, just fork over your money.
I wouldn't be caught dead putting any of this Vivid/AP garbage on my car. ****ing crooks.
