Good info + good videos documenting the detrimental effects of a checkvalve in a WAI system.

 

I just got the new check valve from snow, should I send it back?

 

nah, since u got it, just use it

 

sarcaism?

 

not at all!

unless you got an alternative such as a...solenoid valve.

 

With no check valve. don't you run the risk of pressurizing the tank and potentially spraying meth all over a hot engine?

 

Without investing a lot of thought into it, three obvious options to consider are:

(1) Use a check valve with a light spring tension.

(2) Activate the system at the onset of boost to prevent positive manifold pressure from purging the line back into the reservoir.

(3) Configure the system to trigger a solenoid valve simultaneously with activation.

this is the one, I just got in the mail from snow, what do you think?

 

Did you get a check valve or a solenoid valve

-------------------------------------------------------------------------

"Take a look and see why Snow Performance uses a free flowing, full stainless steel constructed solenoid while our competitors use restrictive check valves.
...........This new solenoid is so effective that it creates less than a 5 psi drop in line pressure!"

Will you be able to do this 2 test to see how much restriction there really is?

1 - pump -> nozzle
2 - pump -> solenoid valve -> nozzle

 

solenoid valve, the one that snow just came out with. Snow's webpage isnt working right now, but its the solenoid upgrade...... So for any confusion.
