Is there a special way to find the a/r ration for a twin divided housing?
I`ve got a KKK K27, the real one, not the one SR Motorsport is selling. I tried to find the a/r ration on it, using the area of both the ex. ports divided by the distance from the turbine wheel center to the center of the ex. ports, but I`m only getting weird numbers.. If anyone would like to help me out, the measurement are as following: 2 ex. ports with 45mm x 28mm "holes" each, and 68mm between the turbine wheel center and the center/middle of the ex. ports. Any help a is appreciated. Here`s some pics of it. Ronny |

Converting to square inches and inches before dividing gives you a much more resonable number. 1.46
It's only 68 mm from the shaft to the middle of the flange? It looks like more in the pictures. |

Yeah I`m pretty sure it`s 68mm, but I`ll take a new measurement just in case. Here`s a pic of the exhaust side, showing the size a bit better.
It`s got a 76mm turbine wheel and 68mm outlet on the exhaust side,and a 87mm compressor wheel and 42mm outlet on the intake side. How many hp do you think it will be good for? |

Both of these lines would have to be 68mm then.
