    Version 2 of my 10mm throttle arms are done. I recessed the hardware a little more and added a 5mm allen for safety. Plus designed up a return spring setup to match! I think I’m happy with this aesthetics.

    Intake is coming along!

    This is Steve from EFI hardwares favorite injector for the L with his ITB, their spray pattern was used in the creation of my intake, with the goal of injecting down the middle of the runner. https://www.efihardware.com/products/2720/Bosch-Injector-347cc-3Bar-12-Height-EV14-E85-Compatible-with-Extended-Nose

    Something sexy to start the week off with. This is a stainless fuel rail for my ITB setup. Expertly crafted by Michel Vienneau! It features injector safety clip stainless cups, built in AN fittings and polished. I’m hopeful it being smaller will allow me to clock my injectors and hide my wiring a bit. Now I can’t scratch it. Michel is a metal magician!

    Another thing to note is the car basically ran amazing off low idle (light street) when tuned. I think that poor injector angle isn't a thing, once the engine is sucking enough air/fuel into the motor.

    I have a ford racing engineer that said the runner shape (sort of S) should have little to no effect air flow in a street car, but honestly I don't know that for sure. Lots of engines have wild air paths to the valve (my 5.0 does 180 at one point). But lots of cars have terrible injector angles. The intake design has 2 big benefits, 1 is it gets the throttle bodies up and away from the header, then 2 is the injector spraying down the middle of the runner. I personally think it looks good. I wished the FET wouldn't have been so poorly made. It would have been a much easier project. One thing I haven't talked about a lot is cold starts, and working with automotive engineers, one theory we have been talking about tough cold starts are from intake walls being cold and my poor injector angels, so higher wall wetting and fuel puddling. Then fuel puddles going into the cylinder, thus causing cold start tuning issues. This is probably my least favorite part of ITB so far. Rough cold starts. I am hopeful that spraying down the middle of the runner helps all of this. But time will tell. Honestly my first intake and throttle setup ran the best (jenvy/ harada). I have also gotten much better at tuning, so I kind of wish I had that setup still to see how I can get it to run. Smartest ITB intake would have been Larrys intake with the injector spraying the valves or the Whitley tune intake. Also haltech is moving away from transient throttle in favor of Map prediction, which I have been told is much much better at cold starts and overall light throttle input tuning. Tuning transient took so much time and I didn't have it perfect.

    I had an injector at the head intake, but I didn't love the looks of it. I know that is silly, but it's how I feel. About 30 degrees tilted up is also an option for this intake, but not nearly as good for the injector angle. I agree about tilted up looks good, it makes it look mean.
  8. DuffyMahoney
    What are you doing with it? I am curious, I have one, that I haven't decided on what to do with it.
  9. DuffyMahoney
    I belong to Classicbroncos.com and to be able to post pictures, you have to pay a small fee. It's not a lot, maybe 5 or 10$ a year. Food for thought. I will donate now.

    I decided to make my own intake, this is modern version of my FET. I love the angle for the injector and also getting the throttles away from the heat of the header.

    EFI hardware is saying a Log is bad, a log is what I have done in the past. Its all a ? They want equal length going to a collector. https://www.efihardware.com/products/1963/map-sensor-collector-kit-6-cyl-inc-hose-for-equal-length-connection

    Finally got my cnc stacks in! They look amazing
  13. DuffyMahoney
    I have 5 progressive cnc throttle cams for sale. 10mm shaft. Comes with everything in the picture. Gives resolution to ITB and triple carbs. Basically more pedal travel for less throttle travel. Should make street driving more enjoyable. So far a few cars are running around with them. 125$ each shipped Pm me or email me m2racing@bumperlift.com
  14. DuffyMahoney
    I have a few progressive cams left to sell, if anyone is looking.
  15. DuffyMahoney
    Finally nailed down a perfect length, bend with proper spring tension to the spark plug! Now off to Thailand to be made.
  16. 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.
  17. DuffyMahoney
    I am trying to get better spring engagement on my R35 Coil stalks. Here is v5. I hope it works!
  18. DuffyMahoney
    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
  19. DuffyMahoney
    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.
  20. DuffyMahoney
    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.
  21. DuffyMahoney
    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.
  22. DuffyMahoney
    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.
  23. DuffyMahoney
    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.
  24. DuffyMahoney
    Will you keep the Mikuni step up?
  25. DuffyMahoney
    Fet V1 for the win! Still waiting on mine
