    this stuff might work better no heat issues with this

    That's very interesting...gonna have to do some research on them myself...?????

    If you just want to "delay" the hit, you just don't hit the button right away! ;)

    If you just need to delay the hit, use a Deadenber trans brake delay box

    Re: What type of Nitrous Controller?

    I installed the basic NOS progressive controller #15835 (only two knobs to fiddle with) on the GTO before DW in '05. The car went three tenths quicker than it had ever gone before on the spray. Really simple and nothing to forget as far as how to use the thing. Just set your start percentage, and the time to ramp up to 100% and that's all.

    The viton tip on the end of the plunger in the nitrous solenoid tends to take a beating from the pulsing as things ramp up, but there are teflon tipped plungers out there that will hold up much better.
    This particular controller is really a no brainer, and has been dead reliable on my car.

    Here are some plunger shots that I had from a few years ago. It's a good idea to "kit" your solenoids every year or two, but frequent inspection is a must. Fuel can puddle in the lines and solenoids and eat things up too. Keeping the solenoids above the level of the plate helps the issue.

    I have a new never installed Jacobs Nitrous Mastermind sitting on the shelf if anyone has an opinion on that or wants it let me know

    Eddie I saw first hand how GOOD your nitrous setup works. I think you are spraying WAY more than I ever will. The thing is I will not be at the track every weekend racing, however I will be cruising the streets on the weekends in a legit 10 second land yacht without the spray. I don't want to do maintenance on this thing every two or three months. The Duster is a GREAT example of a system that works and has proven itself in the midst of a lot of B.S. I still have to wire up dual line locks with a two step, hook up the Nitrous, put on a set of 1.6 rockers, and find some lightweight front seats, oh and buy the wife something for Christmas!!

    My experience has differed. If you get the bottle temp right, and you drive it like a machine, a traction limited vehicle will like the manual method.

    I was racing NOS back in the late '70s early '80's with a 4-speed, and what I've seen even now is not very compelling. It isn't that I don't trust the electronics, but bottle pressure, a staller in the other lane getting you heated up to set the tree really factor in. That why I feel better having control over the button, and a pressure light if it drops under 850 lbs on the bottle. I am sure you are successful with your setup, your ETS do the talking. But I have had very consistent results through the years, nothing as fast as yours, but I have had setups live a long time. I am open minded though, if you can set one up to run 5 rounds on a dial and take home the bacon along with a whole season on a set of bearings, I'm all ears. Tell me more about the Comp setup, I'd like to learn more.

    You will NEED some type of progressive unit if you even want a chance with limited traction, believe me.. If your trying to go "old school" your just playing with yourself. Others WILL have controllers and they are gonna stomp you, plane and simple. Love them or hate them, they are a valid tool to drop ET's. I tried doing the Pump Gas Drags w/o a controller, stopped at Gainsville on the way up to Memphis to test w/ the drag radials, didn't take me but one pass to realize that w/o a way to control the nitrous I would be fodder.

    When I got to Memphis we found an NOS controller w/ the help of a buddy at Comp Cams, put it on in the parking lot of the motel, went to the track to test on Fri., after a few passes to feel things out I was a top three car, went on Sat. and qualified #1 and finished runner-up.. Keep in mind, ALL of this was done with a car that had NEVER been on a drag radial, NEVER had a progressive unit in it, and completely new suspension on all four corners, only thing the same on the car was the paint! I guess all in all it wasn't a bad weekend. Get yourself a progressive unit and learn how to use it. The new NOS unit is a sweet part based on all my buddy Monte Smith has said about it, he works for NOS as an outside rep/tech, and works on some of the fastest drag radial cars and some very quick nitrous Pro Mods, I would take his word..

    I'm going to have to side with Keith, I've wired a few different progressive controllers, and home-built another, and what I found was that it's difficult to get consistent behavior out of the solenoids, most of which weren't originally designed for pulsewidth modulated use.

    Keith and David had an interesting problem with one on the LSR car; won't stay on long enough!! PWM control makes a lot of heat in a small electronics package, likely the issue is overtemp or thermal protection in the unit itself...

    however, back to the problems we had, especially with a wet shot, getting the enrichments to stay consistent during the run was difficult.


    *make sure* you are running some kind of wideband AFR datalogging so you can keep the fuel/air mix in check!!!

    IMO, a good way to bring in power slowly is one of MSD's ignition solutions. Lots of the faster SSO and outlaw 10.5 cars run it with success and consistency, now on an LSR car the delayed timing thing presents other problems (EGTs) but for drag racing with a blower or nitrous, I think ignition control is easier to use.

    Thanks Scott. I have the F.A.S.T. A/F ratio monitor on it now with dual wideband sensors. It has data logging incorporated into it.

    Thanks for all the experience and input. Mr. Ballinger you have a valid point. I am just trying to get in the 9's with a big tank, small tire and full exhaust. Maybe I will install the kit, play around with a 150 to 200 shot in 2nd and 3rd and see how it works out.

    I like a button that hits the whole shebang at once myself. Simplicity and always wet. Come out of the hole without it, bang 2nd and at about 5000 hit it wind to 7000, shift it through on it, get out of the juice at the ET light and let the mph be what it is going to be. If you keep the revs over 5000 you won't hurt any thing. If you are hitting it under 5000 (unless you are running a diesel) you are playing with a rattlesnake.

    Whats cool about the 2nd gear button grab is things things have settled down and a good clean 60 ft is behind you, traction is stable, and you can run it out the back door with the car straight.

    JMO, I'm old school but I've run some fancy guys electrics and beat them, especially in brackets, much more consistent. Plus you can get out of it anytime you want, push in the clutch and not hit the wall.

    Progressive systems are scary!!! Chattering (opening and closing) the solenoids repeatedly wears them prematurely and quite often they will lock up. If you lock open the nos side you burn holes in your pistons, valves, heads,etc... If you lock open the fuel side you wash down the cylinders with fuel and end up scoring the bores and destroying the rings. Look into a two stage setup with a delay!

    What you have to remember with the controllers is they aren't "slowly opening" the solenoid. They're fluttering the piston open and shut to control the amount it's letting past. That being said on anything other than a race application, it seems like a waste putting your solenoids under that kind of abuse. I've seen quite a few fail. The guys running controllers should be inspecting the 'noides regularly.

    If you want something cheap that works (at least for me) try a simple digital timer. Nothing fancy just set the dip switches for the delay you want and wire the output to a relay, from the relay to the solenoids. It won't be a progressive hit, but if you can delay the hit until the car is hooked up then it may help.
