When the anti-lag was armed the ecu would use the dump valve connected to air injectors to dump all excess boost pressure to the hot of side of the turbo between shifts or throttle lift. The excess air would help burn excess fuel and keep the turbo spooled. Of course the rally car would also retard the ignition also so that unburned fuel would enter the manifold but just dumping the excess air works fairly well without destroying the exhaust like a full-on anti-lag does. I guess this might require EFI conversion, CSI may dump excess fuel.


Flame away, it was just a thought.
This came up on Rennlist and supposedly some of the turbo race cars were done this way. However it was thought to do nothing to help turbo longevity. I think the idea was abandoned for a streetcar.
WTB: 964/965 Turbo stuff...carbon fibre bits, Techart wheel parts, RS/lightweight flywheel, 993 EVO uprights, G50 gears or 6 sp., 964 RSR swaybars, custom droplinks and any other cool stuff, pm me! Also a nice medium build 327 Chevy engine.
