Those throttle Bodies look like a copy of American PI's units. Just sayin

Once again, I want the DIS option! eye popping smiley

If I had no choice, Seth's distributor is the way to go, but you still have "moving parts" that need attention (Rotor and eventually the Cap).

Heck, if I could figure out "how" the 'coil on plug' system that modern cars are using could be used that would be another choice. confused smiley

Ted has done a great job figuring out EFI for the Corvair and I thank him for all his work! smileys with beer

There is only so many ways that this can be implemented. I think teds implementation is similar but different, just like many other automotive parts.

Doesn't the old system have noticeably more power with the larger throttle bodies?

The throttle bodies may be larger but they are being restricted by the smaller intake ports in the head. The adapter plates for the old system are tapered to accommodate the size difference.

But the stock carburetors are smaller than the holes in the head.

Well for whatever reason, that is something I never thought of, less moving parts. Ok, I guess I am kind on board with DIS now also, LOL!

Let me first thank everyone for candid remarks. They help guide development and design (even when its not what I want to hear)

Got the Logic (Smart DIS) figured out and have been running one on the Loadside for about 3 weeks. Whats the big deal with that???. This opens up the Coil on plug/Coil Near Plug as they use the same signaling and should have that Tested and running by summer of 2019.


We have started moving toward Crank fired as it opens more options is not very visible.

Yes... My TBI uses the Carb base and an Injector, but I think my design stands on it own. There are only so many ways you can put in injector on a Corvair Carb base (I think I tried about everything). My fuel delivery hat lowers the profile and tries to make it look less noticeable. I have boxes from years and years of stuff that didn't work or looked horrible.

I have also added a Pertronix option that uses the trigger wheel to tell the engine the RPMs. You could even do points.....but why would you at this point.

My biggest limitation is that "Stinkin Job" I have which makes me work 60 hours a week and cuts in on my Corvair time.

Ted my knowledge of the technical isn't much so I will just rely on you for that. I'm in that category of not needing my cars to look factory stock, I do like a clean look for the engine but function beats out style for me. I look forward to your next generation.

So, Ted - With the magnetic pulse conversion in the Corvair dist, with the added Chrysler reluctor and pick-up, are you locking the advance out (both vacuum and mechanical) and using the pulse as an rpm indicator, then the rotor and cap for distributing the coil output?

Yes... I lock the advance (real easy) and let the ECM control the timing. After much though, I have decided to NOT use the Chrysler pickup and use a trigger& wheel instead. This will also open up additional options like Coil on plug/Coil near plug for those wanting to experiment a little and standardize our harnesses. The distributor will only be used for "distributing" the spark. Getting the phasing and orientation correct looked like trouble to get setup properly in the field. The distributor is phased at 25 degrees BTDC and your done. Use of the VAG logic coil is required and makes life easy...GM Smart DIS is even simpler.

The Simplest and Easiest EFI install uses the R2R distributors that you sell. (shameless plug) The distributor module controls all the timing and firing and starts immediately. Trigger wheels have to spin at least 1 Revolution to find where #1 is and then start their calculations.
