I think all of this discussion is helping to answer the original question.
Doesn't sound like bickering to me.
The questioner, as I have, has probably learned a lot about the use of Nitrous by reading everyone's debate and opinion, conflicting as they may be.
I've often used nitrous right at the start of standing-start races to keep the rest of the field from leaving me in the dust.
Especially with older cars that don't have so many gears.
(you're probably saying, 'buy a gearbox')
I mostly use it on really straight stretches.
This is for a couple of reasons.
First the car hurtles forward with seemingly wreckless abandon when the boost is being applied.
Second because it's harder to steer while holding down the Nitrous button. (in GT)
This is doubly true when using MT.
Man, is it hard to use Nitrous in an MT car (in GT) (for the likes of me, at least)
I haven't used Nitrous on such an already powerful car.
I mostly used it on cars with good handling but less than 200hp,
like a Lotus Europa.
So there is a limit (many really) to the advice I can offer.
Do you have a wing on your vette?
Downforce could help tame that thing, I think.
Though, aesthetics could also be a consideration...
Even with these low powered cars I see the tach rocketing through the redline
and get a lot of wheel spin.
The car STILL GOES FASTER though, so I just grit my teeth and hold on.
I've tried using nitrous on dirt tracks too.
This is really scary
and you end up having to break so much sooner for the turn
that I debate with myself about its usefulness.
This is my experience.
Here's some other good information you may have already found.
