VPI Motor Upgrade Kit


Does anyone have any experience with what is described as a 300 rpm upgrade kit for the VPI Scout, Aries, or TNT? If so, would you describe whether any improvements could be discerned?

Thanks in advance!

would there be any need/benefit upgrading to the 300 rpm if im already using an sds?
Depends on which of the three tables you mention you are refering to. I know that some early Scouts reported noisy/vibration prone motors. To my mind the addition of the SDS or Walker motor controller benfits ANY motor running on it. Provides clean stable AC as well as an easy way to switch between 45 and 33 RPM.
im running a scout, a later model, and really happy with what the sds has added. but of course, im wondering if the 300 rpm would provide any added benefit. is there anyone who has just done the motor upgrade with a scout and sds can comment?

thanks
Second what Photon46 said. That's a good summary.

Several months ago HW offered to ship me a 300rpm motor to A/B on my Teres and post a review. That would have been fun and I accepted. It hasn't arrived yet, so I presume VPI's been busy making stuff for real customers.
Coming in a little late here. My question is why do you have to install the speed disc and sensor when using the Teres motor?
