RE: Pulley question
They have actually dyno'd less than with the stock pulleys. Ill find you the link if your really interested. Lightweights are fine and show some increase in response and underdrive are no no's.

RE: Pulley question
Yes, I'd like the info you can provide. From some posts, I note a concern about the weight difference between Neuspeed and other after market pulleys and OEM, re putting the motor out of balance. The local Neuspeed installer recommends them, especially if I am going to chip later, since he's doing a timing belt/water pump change now and does not wish to charge for the same labor twice. What puley is the "no no"? Are there two? I think so. Please educate me!

RE: Pulley question
So a neuspeed installer says you said you should install them and you take that to heart? 
The system is designed to work a certain way and you are now changing that with underive pulleys. Like i said before, lightweight are fine and if you want to spend the money do that.
Before Pullies: 196.5 whp, 233.8 wtq Average over 3 runs
After Pullies: 192.6 whp, 230 wtq Average over 3 runs

So......looks like I lost an average of 3.1 whp and 3.8 wtq with the pullies. The ambient was 2 degrees hotter on the 2nd day but that's not much. And all dynos were done at APTuning on the same dyno, and pullies were professionally installed.
I don't want to recommend or bash this product, I am merely posting my dyno's so people thinking about buying them can make objective decisions. I, however, would interpret the data as indicating that neuspeed's pullies are worthless. Sure, 1.8T dynos aren't super consistent but a 3 hp and 4 tq loss really is hard to swallow when I should be gaining hp. Oh well, live and learn.
That is all.
Update: I emailed Neuspeed earlier today so I will give them a day or so to respond before I give them a call in the futile attempt to talk to a live person who actually knows what's up with the pullies.
