    Any data to back that up? Interesting looking coil

    According to Platinum Racing a few other companies that have test the coils, the head are actually identical. The only thing that Nissan changed was the spring and boot length. Pretty common in the car world.

    I have used all, all have downfalls. Are flares forever? Stainless is very very strong, I would most likely use aluminum in that aspect.

    Does that fit a smaller wheel? Nicely done!

    I think I have all my kinks worked out. Finally time to road tune. FullSizeRender.mov

    What pistons are you using?

    My 2nd set of vintage SK throttles are just about done. Only think left is to come up with a tps solution. They are a gift to my 3.1L engine builder Andrew.

    I decided to put the wiring down below, closer to the header:)

    Well the day has finally come to use a heat shield. This is the one that came with my vintage SK ITB setup. How it installs originally didn’t protect my wiring to the firewall enough. So I shifted it down 2” and then slotted it. I hate the look of sheilds, but it was time.

    I figured out all my issues. My fancy no contact tps sensor has this goofy huge 0 volt rest area. I had it clocked, but from 0-75% throttle the tps didn’t change at all. Then 75%-100% throttle it would move. So it would bounce .00-.15 volts and the ecu thought that was like 0-10% throttle. So clocked it 90 degrees. Starts around 2volts and goes to 4.3 volts. It’s super happy. Somehow this took forever to figure out. FullSizeRender.mov

    Darn!

    You know far more then me. But aren't you casting the intakes? That article is very cool, Rob sent it to me this am.

    I see they say it's tuned not for all out HP but for drivability. Also it's a 3.2L. Which means still over 100hp per liter. Pretty darn epic. I want to know what size throttles? I think Derek needs to try injectors at the head next. I have a feeling throttle response would be better and street use will be slightly better. I have read a few articles on the subject. Closer to head for throttle response, all out hp/ high rpm furthest from the head as possible.

    Heck yeah! I go every year!

    I have them, work of art. Super easy install.

    What level of nerd is this? 10 out of 10?

    I am not even paying for the 5 axis cut! A buddy owes me a favor.
  19. DuffyMahoney
    3D printing is more for test fitment. I have yet to see any real world parts that hold up.

    Lots of tuning to go. But she is alive. IMG_3354.MOV
  21. DuffyMahoney
    Well that is good news!
  22. DuffyMahoney
    I don't expect to sell them. My plan is 5 axis and fancy.

    I still think this engine deserves this data to be made public. I actually thought the engine was in Robs own car?
  24. DuffyMahoney
    The fact Zcar won't release data is so strange to me. Why the hush hush?!

    Final touches on this new R35 coil bracket design. Next is laser cutting for final test fitment. Joseph Monti did a great job with this design, the boot angle was all his idea. Previously the coil boots had a huge curve in them, which we both hated, this splits the difference (22.5 degrees). I also disliked the coil head angle I had originally decided on. This new coil head angle keeps the wiring nice and secured.
