    I have a few progressive cams left to sell, if anyone is looking.

    Finally nailed down a perfect length, bend with proper spring tension to the spark plug! Now off to Thailand to be made.
  3. DuffyMahoney
    I have proper spring engagement! Next is 3-5mm longer in the middle section, so the coils push down completely over the spark plug when installed.

    I am trying to get better spring engagement on my R35 Coil stalks. Here is v5. I hope it works!

    Since my throttles are taper bore. There isn't a velocity stack that looks classic and is the correct size, so I had these drawn up and cnc cut. Sadly I screwed up a measurement, so they have to get cut again. These are 65mm length stacks, which I think make them look better with the shorter throttle bodies. Thoughts? 865c1107babc421bb8381e64ca3a31b8.MOV

    Also I got my taper bore pro EFI hardware 45mm throttle bodies! They are cnc cut and very pretty, the have the most shallow injector angle I could find, and I love the bearings, 8mm shafts and butterfly angle. Sadly they were damaged in shipping, so back to waiting.

    I am working on the stalks now, 3D printing and test fitting how the stock springs will work. The goal is cheaper and rigid like the stalk coils, I plan to make and sell a few of the brackets.

    Also working on a new coil bracket, this one has a built in angle for the boots not to be bent so much. It was cut on a 5axis cnc.

    I got the idea for the angle here. This is a Fet v2 or v3. The issue with those intakes is the middle carb/ throttle is higher. So you can't run a solid fuel rail. Also this version of the FET has 30mm runners at the head. So lots of porting is needed.

    Well I ended up selling my SKs. I am going EFI hardware pro throttles and a vintage FET V1 intake. The FET has about a perfect injector angle and should spray fuel directly down the middle of the runners. The only real issue is they have huge ports at the head, so I will be welding them up and matching to my head.

    Will you keep the Mikuni step up?
  12. DuffyMahoney
    Fet V1 for the win! Still waiting on mine
  13. DuffyMahoney
    Those throttles are interesting!
  14. DuffyMahoney
    I would first look and engine and trans mounts. Maybe something is out of wack? That is an earlier version, did you get it 2nd hand or did you have it for a long time?
  15. DuffyMahoney
    He make some cool stuff!
  16. DuffyMahoney
    One atmospheric, then one post that is balanced between all runners. Which I will already have.

    Rainy Sunday z project! Finally got my cable mount installed for my new cable driven ITB setup. This is a lokar cable to a stock 240z pedal with the ball end removed. Then I made a tiny bushing. Everything is snug and works as it should. IMG_5385.mov

    How about 6 gigantic throttle bodies:) EFI hardware does progressive stock and even does a lower angle on their butterflies to help with the same issue.
  19. DuffyMahoney
    Well my balance bar design is done. Basically i made decorative bolt on injector blanks for my vintage SK throttles. Should work awesome. The goal was to mimic what SK had in the 80s, these are my take on the original block off plates and vac plates. Next off to get cnc’d

    Zcar garage brakes, spendy but very nice and compact.
  21. DuffyMahoney
    Prepping the engine bay for Larry's new injectors at the head intake.
  22. DuffyMahoney
    You will love the Zcar brake setup.
  23. DuffyMahoney
    I can't remember why, but people don't like that dual idler. It has come up a few times.
  24. DuffyMahoney
    Any early tach works perfectly with coil on plug. Sense pulses, works with zero modification.
  25. DuffyMahoney
    That is TBD. One idea is cutting up the LS3 throttle body. A few shops have done that with good success. It's just not a ton of room on a L series for it. The kincer one is very nice, but 2300 dollars for a 40 dollar motor and a nice housing seems far fetched to me.
