Anyone ever used the Driftmotion lightened pulley set for 1jz?

The kit you're describing, is it the one with the aluminum waterpump, alternator, and power steering pulleys? If so I have these three pulleys on my 1jz and they seem to work great. Although I do not have any experience with the harmonic dampener I have faith that the quality will be more than adequate coming from DM.
i have one but i've never used it... i talked to aaron and he says he runs them on all his cars and he never had problems with it, i've also talked to others who run under drive pulleys without the harmonic balancer and they dont have problems as well.
there are so many threads and issues about how bad these underdrive pulleys are, but no one has any proof of how harmful they are. i personally bought and installed the underdrive pulley from driftmotion and i have no problems or complaints about it.
I actually have the complete kit and light weight flywheel and on the dyno I actually made more torque then hp. On stock twins
How long you run the pulley set ups? I heard the damage is caused further down the road by slightly higher vibration, I bought a kit with all the pulleys but im looking at the ATI one because all my pulleys were bent or split so the crank pulley is temp.
fwiw I've had all of them including the crank pulley on my drift car for like 6 months beating the hell out of it with no ill effects. I understand the thinking involved here but I'm waiting to see some damage.
If I can find a good pulley that won't overdrive my accessories I'll probably go for it. But at least in the short term this crank pulley is okay. It's a hell of a lot better than btreaking a stock pulley every other event and flying into walls because of it. before I had the dm stuff I had a few close calls breaking pulley at 70+mph sideways and one 40 mph crash into concrete wall because of it.

Try reading that again.
He was saying that anything BESIDES oem and ATi is crap. The extra comma does make it a little confusing though. Except, I saw your quote and who posted it and knew without looking that there was a misunderstanding.

What if you're building your motor from the bottom up and have the whole assembly completely balanced? Could you just do away with the HB and have no issues with the underdrive piece?
shaeffs post should be /thread. underdriving the water pump is cool (LMAO i guess...) but why? power can be gained by other SAFER resources . Of course its not going to self destruct initially, its long term drivability your sacrifice. Did you not learn ANYTHING here??!?
Reg Riemer, one of the true old school guys, and an honest expert on all things Toyota and Lexus. His is the one that came up with the calculations to do the Lex/550 mod. He made it pretty clear that it was a bad idea, he backed his position up with facts and physics straight for the Toyota engineering books. He has seen the detrimental effects first hand.

If your still hellbound to prove physics wrong, or that they magically don't apply to your engine, then more power to you. Nothing else can be done.

Me, I agree with Dirgle. I won't spit out a bunch of ill informed information,but I offer this line of logic.
The automotive industry is out to do one thing. Make money. So, if the HB wasn't needed, then costs would have been cut in order to increase profit. Toyota must have seen the requirement for the HB, or else they would have went with a cheaper simple pulley.
Buy a new toyota, ATI or Fluidamper unit and call it a day, IMO.
