this is a dyno chart of a stock yaris automatic transmission equipped with a wet nitrous kit running a 50 shot fogger nozzle. timing was retarded when the nitrous starts spraying.

engagement of the nitrous is done via e-manage, using the vtec output.

the owner later increased it to a 75 shot and spun a rod. it is now going through a rebuild with forged internals and will run a direct port system starting with 100 shots.

if anyone plans to run dry kit, you would definitely need to upgrade your injectors if you plan to spray more than 50 shots and you'll need an engine management to richen the injectors when it engages.

personally, i would think a wet kit or a direct port will be best.

His baseline was only 75whp? That sure does seem low sure there was not problems before he started?
