dmoore 687 #1 Posted April 14, 2011 How do you guys measure engine rpm? Share this post Link to post Share on other sites
rmaynard 14,934 #2 Posted April 14, 2011 I have a laser tachometer. Cost me about $8.00 on Amazon.com http://www.amazon.com/gp/product/B001N4QY66 Share this post Link to post Share on other sites
dmoore 687 #3 Posted April 14, 2011 Does it use retro-reflective tape and where do you read it? Share this post Link to post Share on other sites
rmaynard 14,934 #4 Posted April 14, 2011 Stick a little piece of reflective tape on the flywheel screen. Aim the laser at the tape and read. Couple feet of tape comes with it. Share this post Link to post Share on other sites
littleredrider 408 #5 Posted April 14, 2011 Just ordered one!!!!! Shipping is almost as much as the tach....Been wantin' something like this for a while now, can't tell if the motors are at full R's or not.... Share this post Link to post Share on other sites
Toejam 1 #6 Posted April 14, 2011 Can you get more tape if needed? I am real interested in this! Share this post Link to post Share on other sites
dmoore 687 #7 Posted April 14, 2011 Man they are cheap! I'm ordering one as soon as I remember my Amazon password! :thumbs: Share this post Link to post Share on other sites
rmaynard 14,934 #8 Posted April 14, 2011 Can you get more tape if needed? I am real interested in this! Any silver tape such as aluminum duct tape will work. Just cut a small 1/2" square. A roll will last a lifetime. Share this post Link to post Share on other sites
Horse-Drawn 1 #9 Posted April 14, 2011 Good advice, Bob... That's much more cost effective than my MAC digital inductive tach/timing light I purchased years ago, lol. Plus you can use the laser tach on anything, not just engines. Share this post Link to post Share on other sites
JC 1965 1,528 #10 Posted April 14, 2011 Thanks for the info guys. I just ordered one. It's really helpful when everyone shares info like this. :thumbs: Share this post Link to post Share on other sites
