Time for another update, but this time dyno-tuning time.
98RON & 12psi boost:
127.5rwkw @ 5798rpm (about 170kw @ engine)
243.3rwNM @ 4688rpm
I guess I was expecting a little bit more, but in reality the power figure is about right for where I live which is 600meters above sea level, and correlates to Ely’s figure of 136rwkw @ 13psi with his forged engine a few years ago. In his case, and now in my case, the standard intercooler reached it’s peak cooling efficiency, so there was no real point trying to add more boost. In other words, the standard intercooler has to go if I want to make more power. Good news is there’s still plenty of room left in the Supra injectors, which were sitting at about 62% duty cycle, and I have plenty left in boost capability from the GT2860RS turbo.
The power curve (red line) flattened out once the standard intercooler efficiency started peaking out:

Now I’m on the hunt for a larger intercooler. Bring it on!
