This item is on eBay and I was wondering what you guys think about this as a mod to a 400ex? I have a stock coil and if this coil provides better spark, then I'd get better power, but is it really worth it?

 

a new coil will not make a noticable power increase.

Would a coil make a difference combined with say a rectifier and a Dynatek box? or even just a dynatek?

 

IMHO, here is my take on ign setups.
If you are trying to burn fuels like nitro, or alky or things of that nature, sure your going to need an arc welder to set the mixture off.

Gasoline is a different story. It lights off easy and the ign of today are VERY good!!!

IMHO, spend your money on other go fast parts.
