Default Re: WMI tuning and results Part 2

G’day guys,

Thought we’d post a quick update to cover off on all the changes we have made over the past few months. We have now upgraded to gen 2 Garrett gtx3071r, Bosch motorsport 1550cc fuel injectors and an in tank Walbro 460 fuel pump. We also made the switch back to direct port water meth injection, using 4x0.6mm direct port check valve jets, along with 2x0.5mm post intercooler jets and 1x0.4 pre turbo jet.

On the dyno a few weeks ago, with ambient air temps reaching 36+ degrees, the car made 277kw/371hp @22 psi without water meth injection. With the water meth on (using a 80/20 methanol/water mix), it made 352kw/471hp @ 30psi and 388kw/520hp @ 35psi. At this point, we reached the knock limit of the engine due to maxing out the flow of the water meth system. We will upgrade this system in the near future in a bid to squeeze a little more from this setup.

Cheers
