looks like you're stuck... I guess you could plumb your intake direct. I've seen a few systems that go up under the intake...sneaky!

Why is the switch hooked to the front carb instead of the center carb?




The full throttle switch is on the front carburetor because you should only use nitrous at wide-open-throttle and since the front/back carbs are vacuum seondaries basically they don't open up "immediately". Also, the nitrous plates are on the front/back carbs & only a spacer on the middle carb. I wanted to make sure all the carbs are open fully before the nitrous kicks in.

why doesnt the center carb get sprayed ?




I've wondered that myself, but that's the way Nitrous Oxide Systems built the kit. The center carb spacer does have holes drilled (and plugged) where you could put in another set of spray bars. It might be a clearance issue between the carburetors???

Looks cool. I have been wanting to ad to my sixpack car for quite awhile now. Only thing that has stopped me has been hood clearance issue on my Charger. I don't want to change from the factory hood. The sixpack air cleaner already rubs the hood pad.
It is hard to find the nitrous kit since discontinued from Holley.




Yeah, I forgot to mention that I had to clearance the air grabber scoop to clear the air cleaner.

Get the teflon tape off of the flare and compression fittings!! It should only be used on tapered pipe fittings.

With that much teflon wrapped around everything, I would not be surprised to see those fittings leak or worse yet get teflon inside your lines,soleniods and nozzles.

Flare and compression fittings can't be expected to seal with that junk wrapped around it. And by doing so on flare fittings it's almost a given that teflon is going to get inside your fittings. You can't keep it back like you must on tapered pipe fittings.

Plus it looks terrible to guys like me who know there way around fittings. Just trying to help you.

My work bench...couple months ago.

632 big chief pontiac on alky and nitrous injected with race gas controlled by one of the first micro processors, it pulsed the soleniods to keep from blowing off the tires. It had a ton of wiring also with diodes across every soleniod to protect the microprocessor. There was 10 soleniods.
Motor alone was over 1000HP I raced this around 1992-93.
Between the dry sump, mechanical alky injection the the N2O system, this car had I bet over 100 fuel and oil line fittings. I hand assembled this entire car, except I did not build the chassis, a friend from out of town did. I went a bunch of rounds and even won a race with this setup and always finished top 7 or better. One year I #1 quailified at every race, there 8 of them that year.

And there has been cars before and after that one.

I ran one of those plate systems on a brand new 87 ramcharger with a factory 360 with factory quadrajet carburator. It ran 14.00s with it with 33" tires and 4:11 gears. Quicker than the average mustang at the time. Drove the ramcharger to 90K miles and then sold it in 1993, took the N2O off first.
Picture of the ram in the background...no I never ran N2O on a bike, but I did race this. 9.0s at 139 Got my first sponsor on this bike.

I just re-intalled the nitrous system (NOS Cheater) on my 1970 Road Runner 440 six pack & I thought everyone might like to see some pics. Enjoy!




I know that the six pack nitrous systems are no longer produced, but wonder if you might have an old part number for the entire system. I need to price one out, so maybe I'll be able to get some information with an old number.

I think the NOS part # was 02013 or something like that. Yes, it has deen discontinued for quite awhile now. It used to sell for around $600.00. I deal with Holley on a daily basis thru work & even tried to get them to just piece together the plates for me & then I would piece the rest of the kit together. They wouldn't even do that. They say they have no left over pieces. Wonder if we can spark enough interest we can get them to bring the kit back???

Thanks. I bought my system way back, when I lived in the Detroit area, from the old Ramchargers in Livonia. I just could not remember, for the life of me, what I paid for it. Now I have an idea of what to price it at when I go to the next swap meet. Thanks again.

I have a good reason for resurrecting this old thread.
I have a 6bbl 440, and I was interested in a Nitrous spray plate setup. I barely missed buying a gently used NOS 6bbl system, exactly the one described by Purple Beeper (whose car runs great, and PB is a great help on forums).
Nitrous Express makes a 6bbl Holley carbs compatible nitrous spray plate setup, but the CENTER carb is the one that would be sprayed, and the outboard carbs have the spacers.
I'm sure that you can get a 2nd spray plate and switch to the outboard carbs being the ones that get the juice, but be AWARE!
The outboard carbs on a vacuum actuated system, which is how the SB and BB Mopar 6bbl (and Tripower 427 Corvette) is made to work, HAS A LEAN A/F RATIO SPIKE for about one second when the outboard carbs open. Whether I use the spray plate on the center carb, or the outboard carbs, I would have a 1 second delay built in to be sure the nitrous doesn't spray during the lean tip in.

Good catch! And thanks for the heads up for any future users. I dreamed of having a Nitrous setup on my "440 to be" when I was a teen...

ooops, didnt see the post a coulpe above this.



Just an opinion that might save you some trouble, but id junk all but the plates and bend some nicer looking and more well routed SS lines and as well replace the noids with new units that, well that are simply new and more or less take care of a possible issue at the wrong time. You could live with small noids at your power level as well.

I still have the old holly paperwork for the kit in pdf I could post if anyone is interested.

Although cool its stone age tech, the plates, and its easy to buy the aluminum spacer plates off ebay and make your own with the more modern tips on the market. And ive found alot cheaper. Ive still that old kit on a ride and it adds to the cool factor and is great fun for just a bit more kick.

Have fun and be careful, you can only mess up one time and the funs over. Oh, Ive also found modern bottles, tank heaters, ele bottle opener can be had on CL dirt dirt cheap from the ricer boys who toast there setup in short order.
