My "pet project" is a N14 R56 making something in the area of 450WHP @ 27psi (425 last I dyno'd it). I run it exclusively on pump ethanol (E78-E85) with the help of 8 fully sequential injectors.

Ask me anything

 

Since its a Delta GDI, I assume it's DI with 4 extra port injectors?

Feel like throwing down Engine/Turbo specs and some pics?

 

haha you would be absolutely correct. The 4 original DI injectors + 4 port injectors, all firing sequentially. The SCS Delta GDI6 also offers the ability to phase the injectors in/out as a function of load so there are some really interesting strategies that can be used there as well.

All the usual Supertech suspects in the valvetrain

 

Nicely done! Looked at SCS a couple of years ago. Back then the hardware was very capable but the software still needed work. Did they update to load/lambda or is it still MAP/duty cycle based?

 

With the release of the GDI6, there has been what I interpret as many nice improvements. They brought in VE theory some time ago and that now allows VE as a function of MAP/RPM. They've come a long way, though the software still has some oddities here and there that only their development team seems to understand. That said, to their credit - they have been incredibly responsive with software updates and feature delivery (within reason) when requested.

Lambda target is its own separate table which goes by load (MAP in my case) and RPM which trails the precedence set by Link, ECU Master, etc.

 

Update:

Back at the Dyno and the turbo and ports are officially maxed out. Final numbers are 480/380 WHP and WTQ respectively.

The next evolution of this will be to fit a larger set of port injectors as well as either a G25-660 or G30-660.
