NOS Progessive Controller HELP

[StreetKing]

I am thinking of purchasing a NOS Time Based Progressive Controller. Any advice would be greatly appreciatted. We want to put another 50-100hp shot on the car but we do not want it to be activated the same time as what we already have on the car. I know two kits is an option but for the money the time based controller would be a lot cheaper. Any info or advice is greatly appreciatted. Thank You in advance for your reply.

If you go with two kits look into the Digi-Set timers. They can be had for around $100. If you want to up the jetting on your current kit by 50-100 HP and soften the launch you can do it several ways. One is buy installing the controller you mentioned. The other is by installing a programmable ignition unit in the car. In doing so you can put bigger jets in it and pull a few extra degrees of timing out on the lauch....then ramp it back in. Personally, i like controlling the launch with timing, but that's just my preferance. NOS's best controller is over $500, so do some investigating before you buy anything. You may be able to buy a box to plug into your current system and program the timing curve....such as the MSD programmable unit.....for a lot cheaper than a nitrous controller.

Thank you very much for the info.
Whats digi-set timers?
And also the the controllers have you heard good things or do you know anyone who has proven them to work well. the only thing Im not big on is the stunning the silonoids with the controller. Thanks

Digi-Set timers come in two different designs. One has knobs that you turn to set your delay. The other dip-switches. All you do is set the knobs or flip the switches and it delays the power application how ever long you program into it.

As far as the progressive controllers go.....bear in mind that a properly designed controller system has an extra solenoid mounted in line with the others. It is used as a safety feature because the "chattering" of he solenoids that the controller does is very hard on them. FYI, the prices of the controllers do not include any extra solenoids or fittings....which will be another $100 or more. In the event of a failure, the safety solenoid protects your engine from having nitrous weep past the solenoid and fill your engine up while it's not running. If that happens you will turn you intake into a projectile and make a nice opening in your hood for an aftermarket scoop. When the extra solenoid/solenoids are installed they also place more restriction in the line and cause a reduction in flow. If you have a Pro Race fogger that can shoot 500+HP it may not be a big deal. However, if you have a 300HP plate then restricting the flow may not be such a good idea. It really depends on your combination and intended use......

Thank you very much. From your input I now know I will probably need to go a different direction than the controller. I do have a plate kit and it goes up to 350hp so safely installing a controller (with other silonoid) would not be very well for the application of my car. I also thank you for the info on the digi-set timers. I will now do some research on those. Thank you so much!

[Dave Bandt]

Send me a PM with your combination and we can talk a little more about what you are trying to do. If you are using 28 X 10.5 slicks i see no reason why you can't shoot the whole 350 off the line. There are other tricks you can use with plates like increasing the line length from the solenoids to the plate. The longer the lines the "softer" the hit. If you are using a stick or drag radials then things become much more complicated. Like i said, give me some more information and i'll make some suggestions to you.

I'll go along with Dave on using the timing as a retard. I had Jeff Prock set up my fogger and I told him I had a controller. He said they are junk, in his opinion. He said they are extremely hard on the noids. He said the same can be done with timing. Take out 2-3 degress with the ignition for however long you'd like and then bring it back in. So I sold the controller and I'm purchasing a much better ignition. But I've yet to try it out since I keep running out of money to finish everything. LOL
I'm sure Dave knows what he's talking about and I'm pretty sure Jeff does too.
