Purchased a crank scraper (Teflon version) over the Christmas break and now finally have time to install. I was wondering if anyone has done an install, how bad was it, did it take a while to get seated?

Also should I expect an improvement and how should I look for the improvement? Dyno time is obviously the way to go for real numbers, but if the general consensus is that there will be an improvement, then I don’t see a point of a baseline dyno? If there is there a potential for a marked change in power at certain revs I want to know where that is, i.e., dyno is useful, but only afterwards, not before and after.

Some people swear by them, that’s why I bought it, just looking for some practical advise and experience. Hopefully when its done I’ll be saying “thank the IT gods this is legal”

Thanks
