Something was not quite right with the power you made earlier, my EL pulled 270hp(200rwkw) on 5-6psi...
Regarding the motor - you said it yourself earlier, its the tune. You should be able to pull 10psi all day everyday on a healthy stock motor..... |

Tuner said the tune was safe for 8 psi , all I did was swap out the 4 psi spring for a 9 psi . Then set controller to 9 psi with gate to open at 8 psi . I'm guessing the tune couldn't cope with that change and f**k the motor .

Controller wont make the gate open at a lower PSI than the spring setting.
Why did you boost it past what was known to be safe? |

Sure your tuner is good with microtechs but he is a rotary specialist. I've heard from numerous people that the specifics (rules of thumb) for timing and fuelling are quite different between piston and rotor engines. You almost could have done a better job yourself at a conservative tune in this instance.
Definitely a cracked piston or two, and probably a few spun bottom end bearings too by the sounds of those YouTube clips. I feel for ya Corey. Breaks my heart to see an engine grenaded in circumstances like this. |

Well since I had a 9 psi spring I couldn't go any lower so I went to 10.
Xcabbi who do you know that can tune 6 cylinders good running a microtech? Next tune I want it to be a good one .

Could have cut the spring

Kon at Wollongong Automotive Services. He tuned my brothers VL and it had a Microtech in it. It actually went alright for a mismatched Chinese turbo kit. Could break traction in 2nd without abusing the clutch. Just lean on the throttle and away you go.

Cutting the spring is a big no no.
A cut spring is a stiffer spring. But then you lose preload. Unless you have a spring tester or load it up with weights and work out its new spring constant and preload then you are literally playing with fire. |

Sorry to hear about the XR Corey. Maybe look into a "phoon transplant? Or even investigate dropping a 302 in?

One day we'll see first hand just how "sluggish" a turbo 302 is.
