ifcho 0 Posted January 11, 2008 Hi, I was browsing today and I found this: http://jeremiahsviolins.com/grooves.htm Then after some more searching I found a few other topics: http://images.google.bg/imgres?imgurl=http...l%3Dbg%26sa%3DN http://www.somender-singh.com/ Do you think these grooves really improve the combustion as they said or this is just the next hoax?

davemar 16 Posted January 14, 2008 It would be a bit of a crap hoax as he seems to have told everyone how to do it, so isn't exactly going to make any money from it; and it doesn't really cost anything to do apart from lots of time. Whether it works or not, I'd be a bit concerned about the grooves causing weaknesses and hot-spots in the head. In a 16v head there is less scope for placing these grooves. I'd like to see a proper independent scientific assessment of this. Share this post Link to post Share on other sites
