I currently have a pro shot fogger, setup with two solenoids per side; one fuel, one nitrous.

Is there any reason not to use one of the higher horsepower rated solenoids and only use one fuel and one nitrous solenoid to feed the whole system? I am about to order a new pair of Super Pro Shot solenoids, supposedly rated at 400hp each. Since I won't spray near that capacity, wouldn't my needs be met by one of NOS's 600 hp solenoids, provided I don't spray that much? Say, a 400 shot total?

I am thinking about ONE of these nitrous solenoids failing and leaving one working, causing a serious unbalance of horsepower on one side of the engine, the results of which would NOT be pretty!

Having only one fuel and one nitrous solenoid feeding both seems like a safer way to do this.

Thoughts, comments and criticism welcome.

There's only a handful of nitrous users around here. If you dont' find what your looking for around here, you might want to ask over on the Nitrous Forum on Yellow Bullet. Lots of experience there. That said, yes you could move the solenoids and combine them so you have one each feeding both sides, but not sure you'd want to. Properly wired, the solonoids are fairly bullet proof. And even if you lost one solenoid, as long as it wasn't fuel, nothing bad would happen. You lose a fuel solenoid, it could go lean enough to make some ashtrays depending on your tune up.
Believe it or not, running NOS on one side of the motor, but not the other used to be done quite a bit. It's called "banking" and was done before progressive controllers were available. The idea was to leave on one bank and bring in the other bank when traction was better. Lots better ways now a days, but it won't hurt anything by itself.
Lastly, if you're gonna run a fairly small system, less than 200 HP, a plate might be easier and cleaner for you. That's what I run but I only spray up to about 150 HP on a timer. Good luck....

Why are considering changing the solenoids in the first place? If you are only going spray 400 max anyway the standard solenoids are just fine. Like david was saying running on one bank at a time won't hurt anything if only done for short periods of time. If one side failed you would notice the power fall off. Redoing the whole system seems unnecessary.

Thanks!

The solenoids on it are questionable (came used with the intake) so I was about to buy two new ones. Before I did, thought to ask about the difference. Primarily to clean up the install.

I'm over the 200 shot level now and will probably just stay with the fogger.

Love that pic Bob - every time I see it - cracks me up!

Thanks again gentlemen.

You can easily check to make sure the noids are during before you make a pass.

Have someone activate the system while you hold a screwdriver to the top of the noid. It should be magnetic. If it is it's working and will likely work when u make a pass.

Like the others said, if a noid fails you'll feel the power fall off or engine sound different an lift well before anything serious happens.

Felt it fail

A couple of weeks ago I did feel it let down during a pass; and let off the button. Engine picked back up and ran great. I thought I was low on nitrous and was going to change out the bottle. When I hit purge to empty bottle, had white plume, so still had plenty in bottle. Still had bottle pressure as well. I'd been told to hold .005 feeler gauge above top of solenoid and if it snapped down, solenoid good. If it kind of drew down slowly, the coil in the solenoid may be going bad. It drew down -

I also checked each nitrous filter to be sure all were clear and did find a few particles of junk. I tested on the water again Tuesday and the nitrous was there - but not as strong as it was here Second nitrous pass with 620 - YouTube
In this pass it turned the A impeller 7300. Tuesday it only turned 7100. Knowing I had a full bottle and clean lines and filters, I decided on replacing solenoids.

Thanks for the replies. Just ordered two new 'noids! They'll be here tomorrow! Y'all have a great weekend!

Weather

What was the weather like on both test days?
At BB it was nice - I'd say mid 80's to low 90's with low humidity. Rained that morning and weather cleared off about 1 or so.

Two and a half weeks ago - not as nice, but not bad. I'd say mid 90's and 85% humidity. No idea about density altitude either day.

This past Tue - nasty weather. 100. F'n humid. Nasty day for testing for sure. I realize that, and would expect a decline in RPM; but 200? I guess I'm playing it safe by ordering new solenoids, but have no other explanation for the "hiccup" during the pass at BB (that was the 2nd nitrous pass that day - the first felt fine).

I've lost 150-200 rpm going from a track with low da to one with high da.

Possible.

Hey. Anything's possible! That's a lot! I am hoping this will eliminate the hiccups. I ordered the 16048R's instead of the 16045. These had the Teflon seals for only 4 bucks each more. I need to get a weather station I guess, to better track...well. The track.

I'll see what they do this weekend. They are due by 10:30am tomorrow; we have a gathering on Lake Ouachita in Arkansas this weekend and it's gonna be over 100 again and humid as hell Sat.

2, really? Just 2? I don't see the problem.

Seen that b4 hell it would take 4 hours to run the valves WTF

Hiccups - gone

Well. Mixed bag. Had some issues, different of course. Did some testing, changed some parts. The nitrous solenoids are fine. Going to remove the full-throttle switch. Didn't use it for activation, but as a safety to prevent accidental activation while not at proper RPM. It wasn't working consistently, so data on the juice wasn't good.

Boat ran good on motor, but now not keeping pump loaded on the juice. Time to play with hardware.
