Holy sh*t, that is absolutely absurd. Things like this make me extremely depressed. I know what my car makes on this dyno and to see what Joe is making on 19-20psi Honestly, that is awesome, I will be saving up to build my motor shortly. Congrats Joe and good work Nick, as always.

we are also testing a T4 hotside TS turbo on our time attack car... in three different configurations.... and comparing it back to back with an open scroll mani and housing, should be interesting.

You can make 500 atw on a Mustang on one Walbro at stock fuel pressure? Not doubting the result just did not know a single Walbro could go so far.
Was this dyno pull done in 3rd or 4th?
When will you be testing the new Magnus?

Its a rather large turbo. Jumping from a standard 35R to this is night and day.
The TS application is being tested to see if a larger turbo will choke up top (9000 rpm) vs an open volute housing and standard 4-1 collector.
I had initially asked Joe whether or not he would mind the increased lag with this type of a turbo, and his response was YES. lol But, we also had to be realistic. With the bottom end that we built, the head work and the goal of the car, the lag is acceptable. He mostly drags the car and ill rev well into the 9000's. It will give him a great power band in TS form, vs. a slightly laggier open design.
Now keep something in mind here. He is running an 8 lb spring in the wastegate. This was to experiment with using one gate to see how well boost could be controlled. The threshold comes on MUCH sooner. With a 21 lb spring combo, this turbo will kick MUCH sooner in the rpm band. I will post results of that combination with his final numbers next week.
