Do you know what gear it was done in? A lot of dyno operators run in 4th gear. The 8 is supposed to be done in 5th.

What's the common denominator in all this? Never seen so many blown engines in one car before.

the first one was from over boosting and a bent mounting bracket where the turbo bolts on, the second one unknown at this point !

It is fun when you take off from the lights ,using all of first gear until redline (10500rpm) . I need to get it back on eastern creek so I can enjoy it!!

Sorry yeah ... If that's still current then your running out of airflow. Has the engine been ported at all?

only a street port (all the casting dags have been removed ) , my air intake pipe work around the air flow sensor is bigger than standard to fool my sensor and a custom made air intake manifold that is alum.

Generally it's the exhaust ports that are the issue. Pretty sure no one has solved that problem. Ahh well, nice that you can go there but imho would only be useful on a track and for aural pleasure Image
