SBF Crank trigger

[bobcowan]

The big advantage of a cank trigger system is less spark scatter and more accurate timing at high rpm's, like above 6,500-7,000. Below that, a modern distributor is accurate enough.

The other advantage is that with the right ECU, you can get really good control of your timing curve. For an engine that's fairly radical, better timing control through the rpm range will not only give you more power, but make the engine more efficient. Which can equal better fuel mileage.

Been down the ICE track before thanks.

Bob, my engine is developing over 610bhp at 6800rpms. sounds like a good distributor should work for those rpms. ECU are you referring to e.g. MSD 6AL Programmable ignition box or an MSD 8979 multifunction ignition controller.....?

Crane make a Pro Curve distributor with different electronic advance curves which looks good.
