nitrious spool up assist?
Try putting a pre-compressor fuel injector in your air filter, and tap a port into your compressor housing for a spark plug. The rapid expansion will spool your turbo in no time flat.

from what ive seen there was a fd if i remember that they only used the nitrous to aid in the spool up of the turbo, once the full boost is on the nitrous would shut itself off, its like brake boost from a button
I had questions like these in the 20B thread before I went with a GT42R turbo that would spool faster than the non ball bearing I was looking at. I had seen and heard of people using nitrous to spool their turbos and talking to a couple guys at NXpress confirmed this. I do not know the physics behind it, but I do know direct to the turbo can be extremely dangerous and not recommended. I am going to try and dig up the older thread. If you are this worried about spool I would go with a good old TWIN TURBO setup.
Why don't some of you hard heads go take a scrap turbo and blow compressed air at the compressor inlet and see what happens. Yeah..... nothing.... it'll spin as fast as a kid blowing on a pinwheel. It doesn't freakin work that way OK, GOT IT NOW? Now blow that air into the turbine inlet. Wow, pretty cool huh? Its spins faster then pointing it at the inlet, but still not very fast. Now do you get the idea of what kind of volume of air it takes to spin it up? Pointing a NOS nozzle at ANY part of the turbo WILL NOT HELP SPOOL IT UP. Its more effieceint to just use the NOS and BURN IT THROUGH COMBUSTION in the engine to generate enough exhaust to spin up that Farris Wheel of a turbo. Now, in the turbine??? I'd like to see peoples experiances with this as this may actually be plauseable. It just sounds like a bad BAD idea though.~Mike..........

The main point that people are missing which Mike's alluding to here is people use it as an alternate power boost for when their engine isn't under full boost. It provides POWER when there normally wouldn't be any (when the turbo hasn't spooled) And allows you to ring through those low power RPM's quickly and get you to where the engine and turbo pull themselves along well. Whether the added heat/pressure from burning the N20 actually assists in spooling the turbo I don't know. Math would say yes, but the main point is the car will be fast in those low boost revs when its on the juice;.
Wtf regardless N2o is pricey its not worth it in the long haul. I would think if you sprayed it into the turbo it might stand the chance of combustion. What the **** would happen when the N20 would pool in the turbine???????? i know what happens when N20 pools in a intake mani.....bye bye top half.

i have heard of dsm's using an extra spark plug in the manifold to burn off the extra gas to re-spool the turbo, but dsm's with a BOV after the MAF waste a lot of gas out of the valves, so they have a lot more to burn off.
i cant wait till someone's turbo shoots throw the hood from pooling. Nitrous stands a small chance of pooling without a gas mix. WEt systems pool all the time and cause back fires. I have seen a intake launched throw the hood this way. It can still pool as a gas. WOuld be cool i guess to see thw whole side of a motr explode from nitrous backfire. Especially on a rich running car where there is still unburn fuel in the exhaust BOOM!!!!!
