Your setup is a prime candidate for fuel pressure failsafe on the v2

Not sure I understand, but the car has more in it above 40 psi, but I just want to keep the heads on it. Dyno pulls are definitely nerve racking at this power level.

True. Now that the car is dialed in I'm going to employ more features on the EMS like flex fuel and failsafes.

O-ring got it locked down mang! Turn it up, I want to see 1000whp

So you can be the second person who actually has a 1000whp Subaru to post in this thread: http://forums.nasioc.com/forums/show....php?t=1037371

I have a very similar build going on right now.
Darton sleeves
Carrillo rods
Manley crank
King Bearings
Bc 280 cams
Bc +1mm valves
Cosworth intake
Aem ems s2
Exactly twin
And just a couple of weeks ago I order the Full-Race BW EFR 91/80 kit with there reverse intake fmic kit. I'm hoping to get close to the power your making once it's all together. I would be happy with anything over 750.
I also wanted to say congratulations on the 903hp Cam.

From my experience the exedy twins let go around 450-500hp. Mine didn't last very long when I was making 500whp. Good luck with your car and you're going to love the EFR9180.

I meant what made you stop at that power? What do you use to judge as an indicator? I'm assuming det cans would just tell you that you need a new set of rods or head gasket at that power

Oh I just stopped at that boost and power because I wanted to keep the heads on it. I'm sure it would survive at 40+ psi, but since I hit that 900 SAE number I figured it was a good stopping point.

Too cold here right now. No traction.

Beast mode for sure hopefully everything holds together for future runs. How do you like the South Bend 4 puck clutch? Sprung or unsprung? Seems to be holding up at these power levels real well.

Clutch has been great so far. It's a sprung clutch.

The o2 failsafe is pretty quick to setup and doesn't require additional hardware. I think they did a pretty good job with the new firmware.

Great to hear the more options the better I might settle in on this clutch down the line.
