Run really hot and really rich.
If you look at the Comptech supercharged NSX that runs in SCCA/Speed World Challenge, it always shoots flames on downshifts. This is an anti-detonation feature that's been tuned into its engine management so it dumps a bunch of fuel in to cool down the cylinders.

on turbo vehicles, it is more commom on MAF equipped vehicles if they utilize atmospheric blow-off valves. since the MAF meters air entering the engine, when the blow-off valve releases that pressure to the ambient air during a shift...it causes an extremely rich situation.
basically the engine thinks its getting more air than it really is.
ie. like fatbooty said, running rich is the main reason.
ive also heard of h22a motors spitting flame with the CAT removed...probably because of the overlap present at high rpm's.

Some engine management systems have an anti-lag feature for turbochargers that change spark timing with the clutch depressed. I've even seen a setup have an extra injector and spark plug built into the exhaust manifold to ignite fuel and unburnt air to keep the turbo spinning (much like a turbine engine) between shifts.

What happened to the good old honda-tech where we'd flame this guy for pages being a ricer.
All this helpful concise info, in a helpful tone, I'm beginning to feel my place is elsewhere!
