I got the Teflon version. Its a little expensive for a scrapper. Takes a afternoon to fit it. But I/J says a regular scrapper gets you 1% more HP. The Teflon version gets you 2-3%. If true I think its more than worth it.
It can get very close to your crank/ rods. Actually touch them and nothing bad happens.

How long have you been using the scraper? Any issues?

Engine had been together for about 3 years I think. Zero issues with engine in any way.
The engine just started to run like it was supposed to at the end of last season.
Last pass when I hit 2nd engine hit the rev limiter. Might have rolled my sprag.
Drove it on the trailer fine though. Have not been back in it.
