hi guys,
am running a SIIM engine on my Kyosho MP9, its the PGRs21B (tuned) with a SIIM pipe. since i live in Kuwait, we have a local dist here and i was first to buy it ,try and win with it
the engine is great and, durable and delivers constant power, massive lowend power even when very rich. topend is another storey, it screams like crazy, you feel like your running super lean but when you check the temp, you will be amazed that you are still under the 220F barrier
i run it with 30% nitro shimmed at 0.9mm and a cold OS plug (P8). i dont think i will ever switch my MP9's engine to other engine than SIIM. also its not mentioned on the site i think but the rear bearing is a ceramic one. been on the podium 4 weeks in a row and ranked 2nd in the overall ranking behind my team mate who runs a 777WC/ SIIM powered too
cheers
Ali
