blow off valve ?

[snowy1]

I have a powderlite bov in my charge tube and it is not relieving enough pressure when I let out of the throttle still stalls the motor, I would like to try a second bov in the plenum of the innercooler any ideas on a bov to try.

It sounds like your fuel pressure is too high.

No I have it about 2psi, I am going to try smaller pilots and drop the needle see if that helps

No,I mean too much fuel pressure at boost.

Its showing 2psi over boost pressure I don,t know how you would get the pressure any lower as your boost pressure increases your fuel pressure as it goes up.

Another thing that has been causing grief is the choke,it pops open and activates the choke when you quickly let off.To test this take a zip tie and zip tie it closed.

I've tried 2 blow-off valves ,tried tying off the choke,but the best thing by far is having a high idle! When I let off, my idle drops to 3100 then after a few seconds goes down to 2000rpm...no stalling problems anymore!
Also if your tors switch gets activated when you adjust to a higher idle that means your throttle cable needs to be adjusted to give more slack(of course you want to check to make sure that at W.O.T. your butterfly's are all the way opened still.)

I will try tieing the choke I have the idle turned up and plenty of slack but it still does it.

If the tying works a little then that means you're going in the right direction,if you look at the choke bibs that enter carbs at the rack you'll notice that the is about a mm of free travel,bend the little tabs so that the choke bibs are held completely tight,then install a tighter return spring,this coupled with the higher idle and leaner pilot circuit should all but eliminate it.

thanks guys I will give it a try as soon as my new pilot jets get here and see what happens.
