stealth coil? is it hinding?
armored coil can take the most thermal but the weight is a issue...

lol We named it the stealth coil because of the black spun lace. 8 layer flat wound aluminum,stainless steel former,.5in copper tabs that run through the bottom of the coil instead of 2 small vc leads.stealth coil? is it hinding?

I have seen people lose db's switching from a 3" with less power to a 4" with more power.......I think he means that with all the best soft parts, motor, cooling, etc...what is the most power a 3" VC can take before you have to go up to a 4" coil.
lot more factors than the coil, but all thing being equal it really depends on the cone size. The larger cone you go, the larger the benefit you get from having a larger coil because of the mass / bl trade off ratio. The other advantage that NO one talks about is the flux path advantage of motors with larger coils. a 4" t-yoke can carry a lot more B than a 3" before saturation. So the 4" motors are going to have a higher ceiling for B than 3" motors. And of course the L is higher too, so you really get a huge jump in BL^2/Re for not a huge jump in moving mass - especially when the cone becomes large and dominates the moving mass -like its said its a ratio.I have seen people lose db's switching from a 3" with less power to a 4" with more power.......
