I hate to say it but it makes more power and made more snap and pulled farther than my OS Gt2, I was in disbelief and swapped engines 2x to back up what I was feeling. Down side is it drank soooo much fuel it was shocking. It drank as if I was running a Roma,no bs. If I was running the 7mm then the playing field would have been about equal and the Gt2 having a more direct feel and the fuel consumption would have favored the Gt2.
So after that little test I swapped in my spare (broken in) 2024 One part set in the Shimo case and other components and WOW, again it drank fuel but at least at a believable rate . It made a tick lest of the tip in on the trigger but the spool up was a lot more aggressive and pulled longer than the r21 Hybrid, possibly my fastest Gt engine that isn't a Big bore.(Memphisto/Mito 35 GT5) In terms of outright performance these both make my Gt2 look average ..not to mention this Gt2 is an ASM version modified by Muran, hate to say my Hybrid engines with zero modifications run away or will run down a VERY expensive engine that has been modified . Both ran a Rp6 .If any ones has these engines and are bored and want to see what I'm describing ..your welcome ,oh the Muran ASM Gt2 had a Max power ported back plate to boot.
