This is to those whom have them. Are they worth it?? Pretty cheap, 350$ range, just wondering if the power gain is what I see n dyno sheets, in the 10 WHP range. Although my buddy owns a Perf shop and says racing pulleys arent a good idea on turbo cars. Anyway, some input would be nice. Thanks

 

no, no way, don't get them, from what I've heard they will cause loss of hp ant trq.

Wow, thanks for the heads up man!!!

 

Apparently, the additional vibration from the removal of the dampener causes the knock sensor to read knock and it pulls timing. Interesting.

 

I wouldnt rely on hearsay to make your decision. Just because someone has an issue with tuning something and blames it on a different product i would look at all the points of view before making your decision.

 

They only lose horsepower and torque when used with dynoflash.

 

hey from what i have read stay away from pulleys

 

Yea, me too. But I have the dynoflash. SO im just not going to mess with them. Thanks for everyones help.

 

good move...huscroft6

 

You're wrong, if you think your right, you don't understand what Dynoflash is saying. They are saying that the additional noise being picked up by the knock sensor is there PRIOR too then trying to flash the car, and all that "knock" makes it impossible to tune.

If your getting phantom knock for any reason, your car is going to pull ignition timing and be slower, flashed or not. Dynoflash does not change the knock sensor sensitivity or parameters, they just deal with the noise already present.
