blowoff/bypass valve

[FLYBYU]

Is it better to tee off the boost line coming out of the intercooler or at the throttle bodies? This is on an apex with a cpr kit. It's a vortec racing blowoff/bypass valve

depends on which bypass valve you have as to where the lines should go, give us a little more info so we can answer correctly, thanks

I ran my blow off valve off the vacum ports on the throttle bodies, just teed all 4 ports to 1 hose.

blowoff valve works on vaccum, so intercooler wouldn't work,

there are styles that require both, two ports, one requires a vacuum (Engine side of the throttle bodies) and the other pressure (intercooler, charge tube), they work by creating a pressure differential on the two sides of the diaphram which allows higher spring pressures to be used to hold boost better and react quicker when the throttle is closed. so again I say to answer this question we first need to know the type of the valve to know where he should place the line/lines

VACUUM from behind the throttle bodies !
( between the throttle bodies and the engine )

do i need to tee into all throttle bodies or just one

you will get a cleaner signal teeing into all of them
