Nitrous is a hungry beast that must be fed and cared for properly. If not, it will literaly feed on your forged piston and your block. Free oxygen at high temperaures WILL bind with something, regardless of whether it is hydrogen, carbon or iron.
Is this nitrous injected through a single injector before the throttle or directly into each runner? If the former, keep it to a 50 shot maximum unless you have an intake manifold which is wet-tested to flow very evenly. The stock manifold is not that great at flowing air evenly, much less fuel and nitrous. This is not my theory. I've seen the unfortunate results of tossing in too much nitrous through the stock intake manifold. You end up with two perfect cylinders (1, 4) and two useless ones (2, 3).
An EMS AND DIRECT PORT INJECTION is a must for any serious nitrous use.
Using a 200 shot of nitrous is also not going to give the desired results on a CT26 turbo. Nitrous is a great way to get more oxygen molecules into the combustion chamber, but once they separate from the nitrogen and bind with fuel, the resulting exhaust is equivalent in volume to that produced with atmospheric oxygen. The turbine nozzle area of the CT26 is simply too restrictive to allow much more that ~275rwhp of exhaust to flow out, regardless of how the components of all that exhaust were put into the cylinder. You may as well just shove a potato up your tailpipe as use a CT26 with that much nitrous.
Get a big turbo setup, size the fuel system appropriately for your power needs and then you will find that you can hit your 1/4 mile goals without having to play around with fire.
