Solenoid draw on electrical system.

[Cs19]

Im trying to simulate what kind of a draw the solenoids have on my elec. system. So I disconnected the fuel pump and disconnected the bottle and I open the solenoids with the data logger hooked up and Im seeing what I want to see.

Question is...Is there any more of a load on the solenoids when there is fuel and nitrous involved?

[Monty Mikho]

The draw when the pressure is on will be much higher..

Only initially,correct monty?Once the valve is open there is no resistance against it.

By chance does anyone know what Wilson's largest solenoids draw in the amp department?

Thanks!

I got my wilson 2 stage wired up to (2) 30 amp bosch relays,1 for fuel and 1 for nitrous

2 relays for each stage at a total of 4 relays..it sounds overkill but it works awesome

So I would say the solenoids would draw around 9 to 12 amps each,also I have them fused each stage at 30 amps each stage

Ive been meaning to get in touch with Wilson regarding this but I just havent had time.

A fellow racer told me earlier today that Wilson says one large Wilson nitrous solenoid will draw about 20-22 amps while a fuel solenoid will draw 6-8 amps. Keep in mind these are the LARGE solenoids from Wilson.

:D

that doesnt sound overkill at all, that sounds like you have a well set up electrical system..

did you snip off the weatherpak wilson supplys on their kits? I chose to snip of the cheesey weather pak and installed a deutsch connector for the power wires to the solenoids and grounded the solenoids right on the carburetor studs, I would think that is a good ground at the carb but i may relocate to the engine block itself. any thoughts on this?

I used the weather pak connectors that wilson supplyed.If you read the directions from wilson,,they recomend highly to run a number 10 wire from the battery for the grounds for the nitrous system. Nitrous systems usually work off grounds to activate the systems,using the 30 amp bosch relays.
I used 2 batterys with a 65 or 70 amp alternator and do charge between rounds for security.<<Voltage is a must,when using nitrous and MSD controls.
My system is just the 12 volt system.

That being said,,that stops electrical interferance from any other system,meaning electrical feed back from the MSD,,water pump,,and fan if used.

Thats what I did run its own ground to the battery,the ground side.
"Grounds" are real critical when it comes to "hot rod" wiring. Trust me on this one.

If I may ask CS how are you activating the nitrous system? with a button or an electrical type box,,delay box or some type of a timming box?

[Cs19]

I use a button on the steering wheel to activate the system.

[Cs19]

About that weatherpak and grounds.. Did you dedicate one of the two weatherpak connectors to your grounds?

You mentioned 10 ga. wire from the battery for your grounds, Im assuming you ran one single 10 ga. wire to one of the weatherpaks?

Yes that is correct,the statements you said:-D
