Non-Progressive alky kit

Typically tuning around the hit(when it activates). There will be some that will come here and say that their hobbs switch activated kit works great. Your next hurdle may end up being getting a proper pump and setup.

Initially I made on/off systems to have a better price point, in an effort to make systems more affordable. The result was after 6 months of selling those kits, was the only complaint came from those customers. And they ended up going to progressive controllers to fix their issues. I stopped selling on/off systems.. calls went away.. this was a learning experience for me. Needless to say, it is what it is. If you like tinkering a lot with your system, it may work for you. If you want to install and be done with it, then I suggest buying a ready made system.

So it boils down to what your expertise is, how much you like to tinker, and are you ready for the downsides of having issues and figuring them out. And in the end, after you spend money to go in one direction.. going a different may end up not letting you use any parts you may already have purchased. This I see a lot of.

I have been looking at some used systems. I have had start using the car as a daily driver. I had to detune the car to run on 93 . I would like to able to smoke somebody if needed .

If you by a used system, you should have the system tested by the MFG to make sure everything is working as should. This will save you headaches down the road.

You dont want to scimp on things that if they failed, could lead to engine damage.

I have been running a non-progressive system for many years, and the experience is as Razor describes it. A non progressive system has only two positions, on and off, and this fact impacts the way you control the throttle (you end up driving below your alky turn on point, or, once it turns on, you go wide open). For example, my system flows the same alky whether I'm at 11 lbs of boost or 27 lbs of boost (actually more flow at 11 lbs because the pressure in the manifold is lower). I cannot throttle up to 11 psi and hold it there - it will start bogging in about 2 seconds. It needs more boost for the air-fuel-water-alky proportions to be in a range that supports complete combustion.

I am now looking to add a progressive controller. I've needed one for years, but since the alky would work fine if I managed it, I've focussed on other things. I am now shopping for a controller and will rip out my hobbs switch and relays once I find the right one. I'm enthused at the prospect of getting my part throttle driveability back.

You could do a multi-stage setup, with two hobbs switches, solenoid valves, inline T's yada yada..it starts looking ugly and clunky quick (or it needs a lot of painstaking effort to make it look slick)

I have a box full of alky-system parts, nozzles, hoses, pumps, pump heads et cetera which are a direct result of my DIY approach to this. Sometime I think I could have just bought a Razor or SMC kit and been done with it. Other times, I'm glad with what I have learned along the way.

After using both styles, the progressive is way more slick. With my old smc kit turned up enough to quell knock on the top end, it created a bog at turn on so I ultimately had to run less boost than I would have really desired to eliminate the bog. Like others have mentioned, you run into the same problem at part throttle lowish boost, it goes way rich. The progressive kit from razor is really seamless, no issues anywhere in the power curve. The small savings in cost is not worth the tuning hassle with an on/off kit, progressive all the way.

Well I was just going to ask Razor if they was any way I could make this kit a non progressive, The one on the grand national works great but on the Chevy I need it to be no progressive and was wondering if you could do something in the box

Yup.. just crank up the "Initial" and turn down the "Gain". Then setup when you want it to come on using the "Turnon"

If you connect a pressure guage before the nozzle using a T fitting, then you can dial in whatever pressure you want using the GAIN knob. When system fires, it will come on at high pressure and you can use the GAIN to trim how much.

Have your tuner call me and i'll walk him through it. I have never had anyone want this, so i'd be curious to see why.
