[drift a 944]

Remember, this is a 4-banger with plenty of time to charge up the coil, even at 6500rpms. Even with only 3.6ms and only 5 out of 9-amps max-current, it's gotten enough charge to fire off the plugs on a stock 944 or 951. Sure, a single coil can run into insufficient dwell or charge-current when running a V8 at 8000rpms, but it's not an issue for our 4-bangers.

If you're looking to improve performance, time and money is better spent elsewhere to get more significant measureable results.
