This is the primary way to improve torque - spark control. By managing spark and coordinating fuel delivery, you can get very good low end performance in these cars. The trick is not too much advance or you'll get killer detonation in these antiquated air cooled chambers. Before boost kicks in, I have around 36 degrees of timing with 8.0:1 CR pistons. This gives me 496 ft lbs of torque and 525 hp. If I was a bit more brave, I would try 40 degrees to eek out more low end - but I'm very happy where it's at. Most everything else mentioned here just helps HP.
