Turbo launch and then Nitrous.
As mentioned, every story I've seen is about spraying off the line and either leaving it on,
or shutting it off as the turbo's start making the big power!!
I would definitely not bother bringing it in at the end when the thing is making max boost & load.
Especially on a gas engine, I personally would spray something small, like 100-200 the full pass.
Even though now a days more & more guys, including me are running alcohol, E-85
on boosted combo's and then you don't need all the crap like N2O or ice.
