    kawi ultra engine on dyno

    one of our customers own a dyno room and we tested 15f turbo kit engine and ultra stock engine (before we install our turbo kit on it next days)

    Ultra engine es stock produce only 231 hp?? with 95octan fuel!
    First i was thinking we got a problem with our measurement but 15f turbo kit show on crankshaft 388hp at 17ps of boost on Mitsubishi mod turbo (31ps possible) that was exact what we calculate.

    I am thinking there must be something with fuel! quality? we used fuel which is 4 months old. (it was there in workshop.)


    I know rxp 215hp produce in real 191hp.

    that confuse me
