I guess I wasn’t blatantly clear with “I think its safe to guess its not a U.S. motor but I’m still curious.” By which I meant that i think it isn’t even available through open distribution in the U.S. I’m well aware that it is neither IKF SKUSA WKA or USPKS motor and i know no local club runs it near me.
A couple of heavier guys have run Dragons in the SIMA masters class. It’s the the Nordam direct drive engine but with a clutch, which is pretty much the Leopard bottom end with a special head. No relation to the X30 that I can see.
Not a lot of low end, but when SIMA ran the high speed track configurations the Dragons were untouchable, even with a substantial weight penalty. I think it would be dominating in road racing. TaG USA recognizes it as an option for “IAME only classes” like the IAME cup. But other than club racing at SIMA, I haven’t seen or heard of it being used anywhere in North America.
I have one of these top ends (cylinder, head, new piston, & header) ready for break-in. Just install it on a 09 Leopard bottom & you will have one. $500.00 shipped PayPal add 3%… Ron Email: firstname.lastname@example.org
