I am doing quite a bit of Turnpike driving in the KamoKazi...I was wondering what the safe limit is on the 20000Mi motor...It has a Hawk cam, headers, and a Pony carb...I am spinning it at around 3,500 at 60 mph on 30" tires...Can I safely push it up to 4000?
I drove it down to paragon towing my utility trailer with no problems, Up some good sized mountains,so no don't worry about it. That engine will hold up fine as long as you keep oil and antifreeze in it. (true with any suzi engine btw..) Let a aluminum block engine get hot (No coolent ) and Bye bye!
I ran 4K + on the highway with no problems. If you had
5.12's in it you wouldn't like it on the road so much with the t-case. I am glad I had 4.62's in it. The jetting on the pony is good, I had checked it when I put it on (plug chops
at all speeds.)
One thing I thought of was There is a bolt missing on the top bellhousing on the passenger side you should replace.
I was pondering my auto trans swap on the MK3 and thought of that! [img]images/graemlins/shocked.gif[/img]
I agree. Now, I'm running the 1.6/16, but all these engines are about the same. I can run it at 4,000 RPM all day long without problems, and have over 130,000 miles on BOTH my Kicks. There's a company in Boulder, Colorado (Raven RotorCraft) that puts these engines in ultralight aircraft, and DESIGNS them to run at or above 4,000 RPM.
I do regular runs from Eugene to Portland at 4 grand plus, for about 2 hours one way! Over 5 might be a little much for two hours or more but below that, it's quite happy. [img]images/graemlins/cool.gif[/img]
Shift points and peak spikes are not what the question was guys, Sustained crusing RPM's is a
completly different load and gets you into sustained hamonics that can kill an engine pretty quickly,
Size of engine also affects what you can get away with. my 1L has so little mass that it's
practical to cruse at 5200. Not great for a 1.3 and probably terrible for a 1.6. I have shifted
the 1L as high as 7000, but not on a regular basis.
