The Hyperspark distributor will allow you to build a custom ignition curve that fits your engine. Once you do that you'll be surprised at how much better it runs. The engine builder I work with has been building racing engines for 30 years and he is still shocked when I start tuning the engine on the dyno with the laptop. He understands all of this stuff of course but sometimes the engine wants a timing curve that can't be built with a normal distributor. We sit there in the control room and use the laptop to change timing and then watch the vacuum level, fuel flow and exhaust temp. Sometimes you end up with a timing curve that isn't physically possible in a distributor.

On my Coronet, adding a bunch of timing at cruise speed dropped the fuel consumption by a bunch and the car ran smoother and cooler. No loss of power and no pinging since the extra timing drops off as soon as the manifold pressure increases. Very simple to do with a Sniper and you'll notice the benefits immediately.
