Black Friday Mantis sport UD Pulley special

[steved0x]

I was thinking the same thing. I got mine from somewhere else and had to order the bolt separately. I like the Pedro one but it doesn't have any holes so I wonder how you hold the crankshaft in position to torque it. That was one of the things I liked about the RSS one is that it comes with a tool to hold it. I am going to do mine over the Thanksgiving break if it ever stops raining and if it isn't too cold...

I have Pedro's UDP. Small increase in power (less than 5hp) that you'll quickly get used to. No negative impacts to speak of. Is it worth it? I'd say yes.HP gains on these cars is hard to come by especially on the cheap.

I got the Mantis one years ago...black anodized. At the time, I was able to notice the difference in the engine, now I have nothing to compare. I have not noted any significant detriments.....maybe some PS pump squeal on full lock in a Parking garage.

IIRC the belt is still a standard Porsche (Continental) part (jeez I should change that thing). Call or write them and let us know what they say.
