    I've spent a lot of time reading about the fuel system from the official Ford books on the subject, so let me just dump some info here to clarify anything you get from HAL.The S197 Coyote fuel system is, indeed, returnless with a single supply... (see full post)

    This is what HAL says.The 2011–2014 Coyote isn't a fixed-pressure system. It's electronic returnless: the PCM commands a rail pressure target and a Fuel Pump Driver Module varies the pump's duty cycle to hold it. There's no in-tank regulator... (see full post)

    Oh, boy.... my local tuner here in Chile is telling me "I told you so", he found the LU47 to close to the edge when the engine arrived. Great confirmation and thanks for help! I felt comforted since AED said it was fine. But now, thinking about... (see full post)

    Thanks!.... thats more or less what Anthropic it is telling me now and it made me nervous. I think I will run it again and double check. Because it seems that I am in the red with 527rwhp on the LU47 injectors.When we got 527rwhp the dyno... (see full post)

    I found it depends on which AI you use.. Google Gemini sucks big time, its wrong about 50% of the time. Anthropic is something else, I asked Claude to review TMO and then comment. It was pretty much bang on about everything. It basically said... (see full post)

    I wish we had E85 here, the extra power and cooling would be nice, the lack of range would kind of suck though. (see full post)

    one thing I am not seeing here - is discussion about valving. I'd go with Cortex solely for that. Cortex is developed by better/more experienced drivers and true racers, IMHO. I've heard complaints with Vorshlag's valving. Terry tracks a lot and... (see full post)
  • I would just swap to a 26 a spline disk if the clutch is in good shape. That is what Zi did with my Mantic. It saves a bit for something else. (see full post)

    Exedy technical support said it’s all compatible. If it looks badly worn when I remove it then I’ll reevaluate (see full post)
  • Understood on your clutch disc only. My car had the original Ford clutch with only 7k miles. On the bench looks like new. Would a different disc with proper splines work with the old plate? Not worth finding out for the few hundred dollars of a... (see full post)

    AI sux. I tried asking it how to make my car as quick as my friends’ GT4’s and it was insisting it can’t be done. Which is clearly hallucination as @Mad Hatter has been showing us for years. (see full post)

    I recently added the smoked headlights to complete the black out theme for the most part. Maybe someday I will tint the windows, but that is a pretty low priority. Track day on 9/30 is calling for rain most of the day, so won't be setting any new... (see full post)
