My car is running smooth and has no cels.however when I go WTO my car will not boost past 1.7psi. I have an interceptor and a mechanical boost guage. Iat2 is 30* above outside air. What do u think is the problem?

a large boost leak? lol

On a supercharged? Well it must be the manifold to the supercharger that's leakinging?

no

and no

pull the vacum line to your boost bypass valve and see if its ur bypass valve being stuck open. this is usually the problem.. it happened to me the other day.

So doni just get a new bypass valve and I'm good?

So I replaced my boost bypass valve and nothing is different... Anymore ideas guys?

unplug the vaccum line going to the boost bypass solenoid and plug it with a screw then see if it will hit full boost

so there is two vaccum lines going to the boost bypass... the vaccum line from the pod on the supercharger to the boost bypass is the one you want me to plug? if it hits full boost what does this mean?

if you plug it and get full boost, that means that new bbv you put on is also bad. It's next to impossible to leak boost from a s/c car without either cel's or the car running like complete ****. Plug the line, drive around the block or where ever you gotta go and see if that fixed it. If not, post back up.

if you look at the supercharger there is a vaccum line coming out if the intake manifold and it runs over to a solenoid that solenoid is your boost bypass solenoid un plug the vaccum line from that solenoid and plug it there if that solenoid goes bad it can leak boost through it that solenoid controls the bbv and it dosent mean that the one you just put on is bad either

hey guys so i blocked the vaccum lines and it didnt fix anything... So, my next guess is that the vaccum pod on the supercharger is bad. what do you guys think

19transam81

bump it

I have donet the boost bypass and i made sure that everything was pluged up tight. I have also tried to do what i think is bypass the soliond? I unpluged the line going from the supercharger to the pod and caped both sides. still nothing. So should i try the boost bypass and the bypass of the solinid? I still have my new boost bypass valve on even thought it didnt do a thing. Anything else i should try? I can hear a whine coming from the supercharger but no boost. I always said i would never drive a four banger with out boost again. Now i know why i said that, this thing is sooooo slow.

lol that sucks man if you have tried everything that people have been saying and the problem is still there and no fix then just bring it to a local performance shop and ask them and see what they say its worth a try, obviously everything that you've and everybody else has said and tried didnt work.

r u sure you unhooked the right vaccum line and plugged it if so the next thing to do would be remove the charger and check the blades and gasket

K the solinoid on the bottom of the m62 was stuck open. so the cure is a tvs, or fix the broken m62 but the tvs is tooooo funnnn
