JustGav Posted April 6, 2009 Share Posted April 6, 2009 Does anybody happen to know what RPM these engines normally run at and what they can go to? Link to comment Share on other sites More sharing options...
Max Headroom Posted April 6, 2009 Share Posted April 6, 2009 I have a 5hp lawnmower and it can go as fast as I can walk which is about 2.7 miles per hour, on a good day From looking probably about 2800rpm with no load Link to comment Share on other sites More sharing options...
JustGav Posted April 6, 2009 Author Share Posted April 6, 2009 I have a 5hp lawnmower and it can go as fast as I can walk which is about 2.7 miles per hour, on a good day Well, I've managed to tweak the throttle control system, so it doesn't just have the standard start->slow->fast bit.... It now has a proper throttle control (care of a bit of string), Graham S and myself had it revving rather well, but just wondering if turbo-mowing may cause a piston to come out the top Not planning on using it as a lawnmower don't worry Link to comment Share on other sites More sharing options...
PeteA Posted April 6, 2009 Share Posted April 6, 2009 The 23-29cc ones found in 1/5th scale r/c cars seem to have a range of about 2k to 20k rpm or there abouts, so perhaps in that sort of range? Link to comment Share on other sites More sharing options...

Kranz Posted April 8, 2009 Share Posted April 8, 2009 2500 I thought, though I don't know what the safe rev limit is. IIRC they have aluminium con rods, so it won't be very high. Link to comment Share on other sites More sharing options...
