yeah ba mk11. walbro, bosch, surge, ethanol, a great tuner. im running 17 now, and arent too keen on losing a bit of rw power with the hi stall sucking some. 19- 20 psi's a goer I reckon. if I blow it up, so be it. then I have an excuse to put an fg 310 motor in. hey, if I ask my wife for permission to spend 6k on a new motor while im holding a piece of a rod in my hand, the answer is more likely to be yes. no one here is fooling me into doing it, dills. I know the risks. my tuner has said 'I wouldnt but its up to you' ever since going over 14psi. my goal is 400rwkw with a new donk, so I'll have to get one sooner or later anyway. when its capable of low 11's, I'll stop planning more power...
