I put my official guess in ,you will pick up 7-8 tenths with 100 shot.
Need 100 shot advice

A tenth in the 1/4 at these speeds usually equates to 100lbs less weight in the car.

Regardless of how it happened, it happened. And, someone contemplating doing NO2 really needs to be aware of exactly what they are working with. In the case of the car in the picture it may have been an owner-induced failure, but a short in a bottle heater controller or a pressure relief valve that jams will do the exact same thing. As long as I'm posting to this board, expect to see similar posts in any threads I see that speak of adding nitrous. Where safety is concerned it is ALWAYS better to err on the side of caution.

A blow off valve CANNOT jam. All it is ,is a foil disc. But like you mentioned its good to get educated on the pro and cons of anything.

Haven't been too active here recently---too much going on in my life. But you may benefit from reading the 'Land Speed LS' thread in the High Performance section. Since I have actually done it instead of simply 'spouting', you're more likely to get a good view of what is necessary. I would welcome further discussion if you would find it worthwhile. PM with any questions and we can plan to talk on the 'phone if you'd like.

On re-reading, this came across much more harshly than I intended. One of the problems I've found on this forum is the offered negative advice from people who know somebody who knew somebody that... There's good solid info here and you can make good use of it. There's no reason not to spray on the street. If you have a bottle opener installed you can be 'ready' with nothing more than flipping the right switches. Good luck!!!

There sure is a lot of false info here. The burned car is surely a bottle heater as nitrous is not flammable by itself. I went from a 15.3 to a 13.7 with a 100 shot and not much traction. Fuel delivery is your biggest concern and you should either get an xcal and data log your fuel pump duty cycle, or blindly replace your pump. Stock pump only has enough overhead to handle max 100 shot, nothing more (and probable less if your car has any kind of mileage on it). Make sure you replace the fuel filter, and check WOT fuel pressure. 1 heat range colder plug is fine and gap it down a little, no more than .035. And spend the money for a progressive controller, it will drastically reduce the odds of situations like where that kid blew his intake off at the strip. A special tune is not necessary as the fuel nozzle is generally paired with the nitrous nozzle so that the mix is slightly rich to start. Using an xcal to richen it further provides a little extra safety. a wideband o2 sensor is also a smart idea. your system needs to be a wet system and modification of the stock fuel system is required. That isn't an area where you figure it out as you go. Pay a professional if you are not qualified. fuel injection fires can engulf a car in seconds.
You are on borrowed time as you would be with any other power adder. I'm guessing the powdered rods to be the weak link, though I THINK the s type r may use the same construction with its 400hp supercharged version. I have been running 125 shot and go through a few bottles every summer, and i might be pushing my luck with 189K on the clock. Weigh the risks, have fun, and be safe.

The picture I posted did not show a burned car, it showed a car that had its nitrous bottle explode. The bottle exploded because the bottle heater was on and the pressure relief valve failed. The car was parked in the garage. Imagine having this happen while cruising on the interstate at 75MPH. Nothing fake about it. If you're going to mess with high pressure gases, you need to know what you're messing with.

That should go for just about anything in life. A relief valve is designed as a fail-safe...if it failed, someone did something (many somethings) wrong along the way.
oh I see it was bottle failure. yes very violent and very preventable with a burst disk installed and wiring to switched power. normal pressure here in this application is about 1000 psi.
I think nitrous is great on this car and adding it doesn't mean you don't appreciate the car for what it is. if done properly the car handles it just fine and its extra grunt pairs well with the good handling
