Check valve pressure question

Okay Im going to try to confuse everyone what this question... Here goes.

When looking at the enderle K valve the brass fitting on the top of it is a high pressure check valve for when the butterflies are shut quickly at the end of the run to allow the spike in fuel pressure to bleed off with out hurting the pump( pump saver loop if im not mistaken). What is the recommended PSI for that check valve. Dont know if the gpm of the pump matters but here it is anyways.... 13.2 @ 4000 rpm.

As always any help and miss direction is greatly accepted and well recieved.

we run around 200 psi check in the bv and also in the pump saver which is on the pump below the shut off valve

 

Do you route the BV check valve back to the hat nozzle dist. block?

 

not really a question anyone can answer accurately without knowing your system... need to know what your peak pressure is on a run. pump saver should be set just above that

i'd recommend routing it into the hat dist block for 2 reasons... 1) might as well send that cool fuel into the blower rather than spinning it dry 2) if it were to open on the run and you send the fuel to the hat it wouldn't lean the motor out but it you route it away from the motor it could cause a boomer

just my $0.02

 

doesnt that port close as you open the blades. almost forsure it does.

 

Seen a few screw blown cars (ADRL) block the pump saver off completely.... anyone have first hand knowledge??

 

Well, the system is sitting at around 115 or so. so would 125 or 130 be a safe place to start or should it be lower or higher?

 

strange you ask this question...I just got off the phone with Jim @ enderle about this question, he told me to set @ 150# the pump saver only works when you let out of it,,,before and during a run it is not doing a thing? ture or not this is the people that build the K-valve..Dave

 

ding ding ding... prize goes to canter. fuel is basically diverted away or not 'exposed' to fuel. it's your deal so set it where ever you feel comfortable but I know on my stuff I wanna know when/where fuel is going

sudden- your peak pressure is 115#? how'd you arrive at that? i'd address that first if it were my deal

 

I know my pump I run 2 flow meters and a pressure sensor..Dave

 

Got That number out of a tuning system a fellow racer has, its just a rough estimate, I plan on getting a gauge and seeing what I come up with. Unless some one out there has a better way of doing it.

At this point I am just trying to get the system back to what it was when we bought it, the check valve opened at 24 psi, it was putting fuel back into the hat nozzles from what I am understanding(canters replies). I am calling Jim on monday as well to see what else can be or should be done.

Thanks for the help on this one guys!
