Deleting Flywheel Magnets

For those who may know! Rebuilding a 1925 T engine with Scat crank, aluminum pistons, modern seals and etc. Are there any disadvantages in removing the magnets from the flywheel other than sacrificing voltage generated from the flywheel? Can one also remove the coil ring that the mags interface with? I don't want to do anything I will be sorry for later.

Thanks, Racemo
 
If your intentions are a real go fast Model T engine, for a speedster or fast club touring car, with battery single spark distributor ignition or period aftermarket high-tension magneto ignition,... then removing the magnets and the coil ring, balancing the flywheel and adding steel oil flappers to ensure the oil spun off the flywheel ring gear is sufficient for the transmission and to create a good oil mist for the internals, .....then go for it.

Downside is non-original ignition system must be used. Ford T coils are best when tuned and adjusted to the original T magneto output which is 28-30v AC at speed. Lost of originality of the powerplant. If not installing a distributor, then running stock coils on 6v DC storage battery is marginal, running stock coils on 12 DC storage battery is better for performance of a std T engine, but will wear the coil points faster. Replacement ignition like the drop-in True- Fire would be suitable for std engine with T coils and timer. Lack of low end torque for taking off results by removing the spinning weight of the flywheel magnets too, while high end top speed is a positive with the lessened spinning weight. Replacing the magneto system for the next owner will be costly and could detract from the future sales if the T overall is more stock as it sits.
 
From another point of view.
I have three ts and drive them a ton, and all have NO magnets. They use the splash adapters that bolt to the flywheel.
As a ignition guy i understand the purist side of the discussion and the fact that the factory coils worked for years and very well.
Many of our club members wouldnt use anything but the factory set up.

However for me ,give me a distributor ignition and automatic advance all the way.
Much easier to adjust set up and drive down the road....:D

What works for you. Just don't expect other T guys with spare trembler coils and timers to help you on tours when that dizzy goes south.

What do you think is being worked on here? :D

With my Ford , its gotten me home with a dead battery, and at times on 3 cylinders too....can't say that for a Dizzy Lizzie :p
