There are as many fail safes as your willing to buy.

I always wondered if a tiny shot of nitrous on a turboed car just when you get on it, to reduce turbo lag, or help the turbo spool up quicker might be possible?

Thats very possible, mostly only done with large turbos. Spray the nitrous to get the turbo going, then taper off as boost comes on.

Wouldn't a twin scroll turbo just get rid of the lag all together without the need for nitrous?

Yes and no, I'm talking LARGE turbos. Certainly there are other ways to combat lag in the realm of common sized turbos.

The general rule of thumb is don't spray below 3k rpm so if your turbo hits boost at 3800 it wouldn't really be worth while. But if you have something large that takes more rpm's then nitrous could help fill in those lower rpm's.

Trevor Langfield wrote a very good book about nitrous. He is know as the Wizard of NOS over in the UK. He did the nitrous Jag on Top Gear. Its a very good read and discusses many of myths around nitrous use. There is a section on nitrous and turbos.

MotorBooks Workshop also has a Nitrous book, I've never read it but there other stuff is good. I feel like in the days of forums and internet, good old print books often get over looked. I used to read these kinda text books on my commute when I rode public transit. Now I keep them around my shop because they are full of helpful formulas and conversion charts. Most are a little out of date but they are still a great resource.

it would but the point is that nitrous isn't always there, you don't HAVE to use it.
Also from a little research it looks like N2O is cheaper to get set up than a proper twin scroll turbo.

I hardly passed chemistry back in high school but the play by play of how nitrous works is pretty cool, to me at least.

D sport actually did this already, they are running a 50 shot and are making good power about 220whp. I would check out their write up and that should answer most question...it did mine. I'm planning on going with the NX kit for the Fr-s

Nitrous is great and effective power adder. DI engines respond to it very well. Just make sure you use a wet shot.

Also use a step colder plugs and if you are tuned, speak with your tuner about retarding timing a bit. you do not want to run much advance on a nitrous setup.

I came hear to troll but the good jokes have already been cracked.

Plumb the nitrous into the cabin. It will make the car feel like a time travelling Delorean.

I was just at my welding supply store today, I should have asked if then can get nitrous.
