the thing you have to worry about it is.. the tranny. the instant torque created by N2O will destroy the tranny faster than the turbo will.
Using a Progressive Controller will help with this issue. It can delay the full output of the Nitrous by milliseconds, therefore decreasing the instant torque that can break things.

^^^^How much were you spraying when you ran that 15.2?
15.21 @ 89.5 mph "Speed is not what kills, it's the stupidity"

I just got back from the Carlsbad track. I ran a 15.17 @ 94.21, no nitrous.
Please re-read my sig. Sounds like we run about the same, although your mph is interestingly high...auto correct?

From the NOS Website

Nitrous Progressive Controller (which can essentially alleviate the problem with breaking something due to instant torque, the main disadvantage folks say nitrous has over T/C S/C....not an issue if you use this), see below:

"A major concern of any racer is being able to "hook up" for optimum performance. This is especially true of cars equipped with nitrous systems, as applying hundreds of extra horsepower can often over-power the traction available with a given chassis, tire and track condition. Through applying nitrous gradually, or in stages, it is possible to give the car as much power as it can handle at any point on the track. Extensive testing has proven the use of NOS controllers to dramatically lower elapsed times in many applications.
Programmable Progressive Nitrous Controller
This top-of-the-line unit can be programmed to control both the amount of nitrous that is flowed to the engine (from 0-100%) and the time desired to "ramp up" from first hit to full flow. For example, you can program the controller to flow 25% of the nitrous 1.5 seconds into the run and increase it to 75% nitrous at 5.3 seconds. Or, it can go all the way to 100% much sooner. This enables a racer to "fine tune" the power curve of an engine to best utilize prevailing conditions. It can also be used to activate a retard box or 2nd stage of nitrous. Clearly, this is the most sophisticated progressive nitrous controller available today. However, it is very easy to use, and each function is set through simply turning a series of dials to the desired position and pushing a "program" button.

NOTE: All NOS controllers are safe to use with any NOS solenoids. Other manufacturer's may have excessive draw. Nitrous solenoids should not exceed 10 amps; fuel soleniods should not exceed 5 amps."

also there is this thingy from NX, that moniters all the important engine crap, and can be set to gradually step up the dosage during mid spray...

Same concept, different designs...

Personally I like the NOS version better so far because it looks like it might be more user friendly. I don't see how four buttons numbered from 1-4 can be as ergonomic. Of course, pictures don't tell everything. I'm only beginning to research the "Next Generation" version of controllers.
