At the 1200 HP level, that Supra is at the very LEAST using 117 octane race gas. Making 1200hp with only 3L displacement means packing a lot of highly compressed charge air in the cylinders which leads to heat and detonation.
Methanol and nitrous are often used to combat heat and detonation in these cases, more so than contributing power. Many cars use a small 25-50 shot of nitrous that cools the intake allowing for a few more pounds of boost and timing that return more power than the nitrous itself could deliver.
Most Supras that I've seen seem max out around 7-800 RWHP on pump gas and require nitrous or methanol for the evaporative cooling effect alone to support the 30+ psi boost levels required to push over 4 digits. Most cars in that level are also sporting fully rebuilt HKS or Titan 3.4L stroker bottom ends, and stroker motors LOVE boost (maximum effect of boost is apparent when the high density mixture is still pushing hard to BDC through the point when the crank and rod are at 90 degrees)
Example of the effects of air charge temperature under high boost: This Cobra jumped from 800 RWHP to 900 RWHP for a 100 RWHP gain simply spraying the OUTSIDE of the intercooler with a small nitrous mister (ie: no nitrous introduced into the intake or ingested by the engine).
