Lexus SC + GT4 = Eyecandy!

This did often happen on downshifts.
I don't know for sure, but it's probable that a car with straight-through exhaust with no cats can shoot small flames, even if it's NA.
I know rotaries such as the RX-7 look like flamethrowers with unrestricted exhaust.

most cars can shoot fireballs if you remove the cat converter and run straight exhaust with no restrictions, when i was 16 i got a neon and removed the cat and ran straight 2.5 inch exhaust and it would shoot fireballs if i revved it high enough

"Generically speaking, the term anti-lag refers to a technique commonly used by WRC style cars to quickly spool a turbo while the car is under hard deceleration in anticipation of the hard acceleration that's likely to follow. The technique involves retarding ignition timing so far as to cause the exhaust valve to open well into the power cycle, resulting in extremely hot and explosive gases rushing past the turbine, spinning the turbo up like crazy.
While we don't provide a full-on WRC style antilag system, we do provide a very effective drag style system that operates at the line and during those hard power shifts you make down the track. This helps to quickly spool the turbo for those pesky pro-trees and keep the turbo spooled in between shifts. Combined with the no-lift-to-shift feature, this can have a dramatic impact on 1/4 mile times."
When it comes to launching, Anti-lag + AWD =
