All right, I have been running my NOS dry kit for a while, and am very happy with it. However now that I am running an 80 shot, I can't keep traction when the nitrous hits. I currently have two solenoids (only need one), and I'm thinking that I can add one more for fuel, and reconfigure my car to run either a 35 or 50 shot dry, and hit a switch and go to 125 wet. My questions are should I run two separate bottles (which I already have ) or just run one bottle and split it to the two different nitrous solenoids. I have an OBX FPR that I am going to put it sometime soon, along with my cool can. I was thinking that since I am doing some fuel line work, this would be a good time to do this. I am thinking that if I run a 35 shot out of the hole, I can hit the 125 at about 60 MPH and really get an extra kick. I have no problem setting up the switches, but if I do the two stage kit, should I run it off of one bottle, or two? If I run two bottles, I need another heater, and guage to keep up pressure, and know where I'm at. But what if one bottle is running empty earlier than the other? I have been keeping one bottle full as a back up, and filling them up when they are both empty. I have also heard of people running a little fuel tank for the wet kit, and keeping race gas in it to prevent detonation. Any input is greatly appreciated.

 

You don't need 2 bottles for a 2 stage, I am currently running a 50 out of the hole and then the second stage after the 1-2 shift (another 50-100).

However, mixing a dry and wet on the same setup????? After running the dry kit for a year and switching over I would never go back. Just don't like the high fuel pressure thing.

It is technically feasible to run both as a 2 stage, however you are experimenting in territory I haven't seen anyone else go.

Although the 2 stage is an improvement over the single and helps traction its still not enough so my next install will the the NX Maximizer which is a progressive nitrous controller. It can be programed for each individual gear to start and end at whatever shot you want with any delay you want. Plus it can be setup to shutdown with a lean A/F ratio, rpm etc.

 

I was going to set it up so that the 50 shot dry is turned off when the 125 wet is turned on. I was figuring that if I have the dry set out of the hole, I can switch to a big shot in second gear. I can use the dry kit as it is, and just basically add a wet shot for the main event. How much time are you taking off in the 1/4 by running the two stage versus just the single? Have you seen anyone running a second fuel source to spray race fuel with the wet kit? Just an idea...

 

Won't that be crazy to tune? Your fuel pressure is going to be all jacked up w/ the dry shot, and then it's going to have to drop back to stop levels when the wet kicks in.

And Jime I believe did run a secondary fuel source using race fuel for his wet kit. At least he did on his old setup, there are pics around somewhere.

 

I thought most 2 stage setups had two different nozzles. One initial and then after a certain speed the second nozzle would kick in increasing the amount of nitrous. That would include just one tank.

 

Theory sounds ok but like Shadow says the fuel pressure will be jacked for the dry and then have to drop back to stock when the wet kicks in. I guess worst case would be on the rich side if pressure didn't make it back down immediately which is better than lean.

Also like Shadow said I do run a second source for nitrous. I did that on my 95 and run pretty much the same setup on the 2k2. You need a small fuel cell (I was using a 1 gal, now it just a 2 qt humidifier container) pump, fuel pressure regulator etc so its a self contained fuel supply. I use a stock fpr and an external pump I got on Ebay for $30. Its pretty simple really and allows me to run 114 unleaded which is the main reason for using it. Keeps the detonation beasts at bey.

I have run a 12.3 with a 35/35 and a 12.1 with a 50/50 which is much faster than I can run with a single stage. Anything more than a 50 out of the hole produces mega wheelspin. On my 95 I ran a 150 out of the hole and did 1.75 60's but not with the 2k2, there is that much more torque and even now with my 24.5 slicks it won't handle it, thats why I am going to the Maximizer so I can bring it on smoothly.

 

I will be running two nozzles, one that is in there now for the dry, and another that has the two inputs for fuel and nitrous. I am thinking that for now, I will run just off of the gas tank, and work towards the second fuel source a little later. I was also thinking that the change from 50-125 would not be instantaneous, but staggered for a 1/2 second or so. Turning off one switch, and then activating the second, I could wire it to all go at one time, but I am sure I will play with both, and see which works better.

 

i wanna dual stage
