  • Opinions on Nurex auto advance system

    Gentlemen, as I compile the "wish list" for my new 29 Tudor, the Nurex system is one thing I am considering. I know the purists feel this is an affront to Henry's creation, but I'm not building a fine points winner. I plan to drive the car for a while to get the feel of the Model A as it was designed. I would like feedback from those of you that have first hand experience with the Nurex system.

    Just curious what advantage will that be for a stock Model A. Will it run faster, start better, better gas mileage ?

      Faster with 40 HP! Mark in post #5 answers the last 2 questions with better starting and gas mileage. Gas mileage is not one of my major considerations but reliability and drive ability are.

    There are quite a few guys in our club that are using the NuRex timing advance system.

    Here's a 12 minute movie on installing the NuRex timing device:

      I emailed Tom @ Snyder's in the past and asked about this item. I told him I have a 6:1 head and wanted to know if this will work for me. He said the best thing to do that they have found would be to stay with the original advance on the column for now.

        im a 100% believer in it, Used in for years and loved it., Better starting, better gas milage, better pickup as the dizzy spins down as you slow and stops the "lugging". i have since removed it only because i am now using a B dizzy and it has it built in and i LOVE IT...well worth the money for the Nu-Rex in my opinion.. OH and i ran a high comp. head during the entire time.

          Yup, remember you have a high comp head so your faster to begin with, now with the nu rex you sill see a difference, the car will drive great as you slow down and speed up you will feel the difference in the way the engine responds. Just had a buddy install in his cabriolet and he won't remove it now....heheh

            I had one in my coupe, and it was fine in the summer, but would stick in the winter and after a mile or so, would free up and advance the spark. I took it out and sold it.

              I have had one in my 1928 Coupe for almost 7,000 miles without a problem. I love it and have removed the control rod from the steering column to the distributor to keep from adding advance to the centrifugal unit. I also pinned the upper plate in the distributor so it does not move.

                Starts easier? My all stock A's all start on the first two turns when cold; when warm, they start almost inmmediately on the first turnover, because they are set up correctly. Gas mileage? I don't own a Model A for gas mileage. Go faster? I drive my Honda when I want to go fast; I drive my Model As when I want to let go of driving fast.

                My decisions here have nothing to do with fine points or judging. I maintain and drive my cars in as close to 1928-31 standards as possible so as to experience the engineering, limitations, fantasy, and mechanical genius of the Model A Ford. If I wanted a different kind of experience, I'd buy a different car. Everybody has their own ideas, of course. This is just my story, as it has been for 56 years of Model A ownership.

                  I have been and will continue to be a firm believer in the Nu-Rex centrifugal advance unit, and I personally run one in my '28 Tudor and love it to the point of removing the rod from steering to plate.

                  I think I just finished an article here about a small modification that I feel should be done to attach it to the oil pump drive unit so IF you ever need to remove the distributor the advance unit will stay in the oil pump drive and not lift up from the drive and wind up in the valve valley.


                  Check it out.

                    When you called Nurex did they ever hear of that happening?

                    Well.......he didn't come right out and say he knew it was happening, but he also didn't say it wasn't. He did however admit that there would be no harm in using a set screw to insure it doesn't happen.

                  I am seriously thinking about one of these units.

                    Which way is best, Original with Nurex, Model B, Mallory, or electronic. And there seems to me more than one model of Nurex. Automatic advance is the goal.

                    Distributor RPM, mechanical advance
                    by vonheine
                    In the late 1970s, my friends and I used to hotrod V8 engines. We used to modify the distributor power curves by changing the weights and springs so that the mechanical advance would meet our specifications. We had access to a distributor machine at the trade school from which we all graduated from to confirm the modified power curve. I want to build a simple mechanical advance mechanism for a standard...

                    Nurex Advance
                    by Mitch
                    Okay so there is always chatter about how great the Nurex Advance is. I drive my cars with the lever around 9:00 or a little less. I can climb hills, idle, and just about drive on all terrains by leaving it alone. Of course when starting the car it needs to be in the up position. I think most feel they have to continuously be moving the darn lever in order to drive the car. Why should I buy one?

                    Nu-Rex automatic timing advance
                    by Poor Boy
                    Good morning. I came across a Nu-Rex automatic timing advance . Does anyone have any experience or comments on using these? I printed off the instructions and they appear to be fairly straight forward. It states that there is ten degrees of advance for every thousand rpm, or thirty degrees at twenty eight hundred rpm. I was thinking of trying it on one of my engines, probably the B. How does...

                    What will happen if I were to place a Model B distributor, or any other centrifugal advancing distributor atop a NuRex centrifugal advance unit?

                    Alternate Distributor
                    by DaWizard
                    Ok, a bit of background first.

                    As some of you know I have been an advocate for the NuRex centrifugal advance and have been using one for 2 years without issue. Well, after reading the threads here about the advance and needs of the HC heads, I decided I would search for an alternate centrifugal advance distributor.

                    See, the stock engine with the 4.2:1 compression heads are

                    by DaWizard
                    Now, I know this has been discussed in reference to the FSI distributors and high compression heads, but I need to get just a bit more info on the stock distributor.

                    I now have in my possession a Snyders 6:1 high compression head and I think since I can't afford a Mitchell OD it will be the next step in the ever changing "Touring Tudor" named Wheezer.

                    Why is the Model B initial timing so advanced?
                    by alexiskai
                    I've been doing research for a video on ignition timing, and I realized the Model B's initial advance setting of 19° is actually really high. The Model A's initial timing is 0°, and if you look at the distributor settings for later V8 Fords, their initial advance is in the 2-4° range. Even on modern engines, standard initial timing is usually 10-12°. Why 19°?

                    The best theory I have...

                    Nurex Ignition System Questions
                    by conaway2
                    We’re working on a club member’s car that was professionally restored 10-15 years ago. It’s stock except for an alternator (12V, I believe) and a Nurex electronic system.

                    the engine is running rough - occasionally sounds like it’s hitting on only 3 cylinders. It will not idle very smoothly.

                    We’ve cleaned and adjusted the Zenith carb, cleaned and adjusted the gap...

                    B distributor advance
                    by Greynomad
                    I am soon assembling another engine for myself. It will have 6:1 CR, slight cam, down draught carburettor and B distributor. I will be fitting a B timing cover. With that CR, I think I should be aiming at 23° advance. So, where do I set the timing? ie, how many degrees does the B distributor advance and how much advance does the B timing cover give over an A one? Once I know these things, I figure...
