0.24

wow. please go kick them in the nuts first off.
and any shop that would change a 0.40 gap to 0.24 with the addition of 1lb of boost, would be my first place to look for a **** up.


I strongly recommend you put the S2 pully back on to rule out the issue of a pully problem
im almost certain its something that shop did.

 

i'm guessing boost bypass valve doesn't sound like a vacuum leak to me plus i think you would hear it

plus i've had mine blocked off since i owned the car and no problems and i have 26k on the clock

 

yup..i rulled the spark plugs off since they are properly gapped and brand new....

belt is on properly for sure...

maybe leak

so u think it might be the valve?some ppl tellin me to do it,some are sayin dont...im lost

 

i thought you were already in the process of doing the boost bypass mod to see if that was it.

 

i was,but someone told me to stop and not do it....

also i dont knw if it matters or no,but when i reset my boost guage it doesnt go to 0 like before...its bout 3-4 lines under 0...stays in the vaccume zone

 

Well that seems right cuz your not in boost idle you should be under that 0 line. Have you seen if you can go over 10 psi yet since you reset it?

 

yup...i hit 10psi by 3500rpm or so..and holds 10psi till 7k..doesnt go up nor down..just stays at 10psi

 

Boost bypass mod takes 1min to do and a trip down the block,just block it off and take a cruise around the block and let us know what you get

With the above info its either slipping belt or bypass valve you hear no squeeling so i think that rules belt slippage plus you have a stage2 belt so i'm leaning strongly towards bypass valve

 

I second that.

 

sounds good to me...do i plug the hose that i pull off the manifold and wat about the actuator Power Supply,do i disconnect it and leave it connected?

 

If you didn't live so far away i'd stop by and help you but skokie is a cruise for me

is the squeelin suppose to occur at idol,or while driving the car when the revs go higher...it does squeel when u turn the car on after it has cooled down,but once it warms up its perfectly quiet

wanna meet at woodfield tonight..ill be goin up there tonight around 9pm or so

 

you have the stage 2 belt right?

 

correct..s2 belt,s2 tune..dealer installed and tuned

 

Weird your belt shouldnt slip unless you go under 2.8"... but i guess its possible.

 

no thats to far for me when i have to be up at 5:45 am and it should start squeeling when you really get on it and plug the hose of that goes from the manifold to the soleniod and then plug off the soleniod nipple that is now exposed.

 

I think your gauge = fucked.

 

Here is a good article on how to do it.

just put in redline forums . com in the star section

 

the gauge is acting weird tho....its not building boost smooth..kinda like hesitates..goes stops goes stops and holds redline...

 

should you disconnect the neg battery terminal when installing the smaller pulley? i am getting about 16psi with my 2.9 pulley, on my gm stage 2, stock plugs. i did feel a difference after i installed the smaller puller but should i disconnect the battery to reset the pcm? or does it not matter

 

no one asked this yet. Does the car feel like it runs stronger?? does it feel faster??? at idle i see -20 vac on my gauge and i get 13 psi max boost. i am on a stock pulley and 9200 miles

 

car does feel little stronger...idle vac is -19,-20...

i tryed the boost bypass and there is little diffrence...but still 10psi

 

weird..........

 

I have to agree with you. Spark plugs have nothing to do with how much you will boost. It has to be something with the install. Inspect every aspect of the install. Also check the pulley grooves. Is it tensioned all the way? Pull on the belt with your hand and make sure its tight. Don't know what else could be the problem.

 

well il try to put the s2 pulley back on and see how the boost is with that pulley
