I was thinking about adding a 100 shot. What is the safest type of kit to run with a turbo? I have never giggle gassed a forced induction motor before.

 

safest is a direct port injection, but a wet shot is fine. A 50shot is about the max for a wetshot and maybe 75shot if you do a direct port. Anything more and your playing russian roulet with your engine

 

glad I asked the question so basicly to keep it as safe as possible I would nopt want to bigger than a 50 shot. how about in terms of the saftey swiches, I want to run a window and WOT. should I swap out my FPR an fuel pump too?

 

Honestly, since you've already got boost, look into upsizing the turbo and required associated parts. Done properly, a one-power-adder car (in my mind) is ideal. Not to mention, since you're running a turbo, you don't have to stop and refill it. I'd upsize the turbo and possibly consider nitrous in a lag-killer fashion if the turbo is big enough, but other than that, since you've already got boost, make the most of it and build on what you've already got.

If you're set on adding spray, I would get something that can be controlled electronically (not just an activation switch under the carpet) - you want a system that is controlled by the ECU, so that if certain parameters go out of range, the spray will be shut down and the timing pulled back to safeguard the engine. This is important. I'm not sure who offers such a setup, but if anyone, probably a reprogrammed (or custom programmed) GIAC chip would be the way to go to handle it. And usually a wet kit is recommended over a dry shot, just to be positive you have the correct amount of fuel to feed the spray. Finally, be sure that your injectors and fuel pump have some reserve capacity (ie, you're not running near static already or maxing out the pump), so that if you're boosting and spraying, and something starts to falter, you won't lean out and blow up your engine. I would absolutely add an EGT and a fuel pressure gauge inside the car to keep an eye on things. Probably would be good to pull the timing back just a hair (unless you get software to compensate here and do it automatically when the spray comes on) and swap down to a colder heat range spark plug set. Finally, remember that a big shot of N2O is going to create a lot of additional torque, so you're going to want to be sure your clutch and brakes are up to the task.

There may be some model-specific variations on this, but this is general N20-use info.

 

I was told that a ignition system from msd also helps with nitrous, not sure if thats right or not, anyone know? That could just be for other cars?

 

Nothing wrong with adding nitrous. It can give you incredable gains for less than $1k and you still have a very tame daily. Also the injectors dont inject fuel, the nozzles do.

But anyways, 50 wet shot, pull a couple degrees of timing, walbro 255lph fuel pump, and shooting past 4k and you will be fine. Also on a turbo car, a 50 shot will add closer o 60-65whp.

 

Other cars, we have indiviual coilpacks

 

That makes sense, my friend has a Talon so that he would need.

 

thanks for the input guys. Yeah the reason I was looking into the nirous was because I want to keep mellow for the daily drivng and be able spice things up a bit every once and a while.

 

I think you saw me talking about it and wanted to join in on the fun [8D]
