just to chime in agian I may go with clear image pipes they are steel and use a short run method and may be even less than dejon plus I may be able to get them un coated which IS FANTASTIC. so I can get my own color done at Oklahoma high performance polishing. (watch the x-men movie and look at the great job they did on wolverines claws)


I will be running the synchronic BOV re circulated. With probably the gm intake if it come with the kit or the steel dejon intake . I will modify either intake to accept a hose from the bov. I will run it in its normal state so It will function exactly like the stock bov but have a better response and hold boost better.

BTW WTF is with the block off plate there is no way to block it off it would leave a hole in the turbo and it wouldn't be able to properly create boost all you nee to do is take the vacum line off it and put a washer or too behind the spring and BAM no more stock BOV.
IF I AM WRONG PLEASE TELL ME!!!!!


ALSO getting a "custom" downpipe made. just taking the stock one and cutting off the cats and putting straight pipe in its place. I looked at the design of the stock DP and have found nothing wrong with it except two cats.

for stock downpipe reference.

This should take care of the CEL.

If it were that easy then you wouldn't need a block off plate. Just take the stock plate out and replace it with a block off and leave the spring in.

kling1022

yeah that definitely won't work

PimpLay2

no need for delete plate man

ok so two different answers. I know that when I took the vacum source off the stock one it wouldn't open up under boost. did this as a test. Why can you not use the stock plate with washers behind it. Does it not give enough pressure even if I compress the spring more? does it leak boost through the vacum nipple because I can cap that. does the block off not use the stock diaprham and spring?

I'm receiving the Synapse BOV soon and will send it to Dejon so they can weld the flange for it.


By the way, do I or do I not need the block off plate?

08BlackSS/TC

yes you do need it and hook the vacuum source that comes off there to the BOV

Thanks!

cereal83

where is the stock bov?

kling1022

yeah where the intake pipe goes into the turbo. Just follow the intake pipe and you'll see it. It has a tan cover with a vacuum hose coming out of it

cereal83

ok I will go look now. I just took my air intake out and went for a drive and year you can year the stock bov alot more.

Now i go back and try to find the bov but its packed back there and I can barley see anything

Can you please explain why you need the block off plate? does it not just increase spring pressure or does it replace the spring and hold the diaphram in by its self?
I am confused on the physics behind needing one when I can already increase spring pressure by moving the spring closer to the diaphram.

08BlackSS/TC

Think of it this way, why do you need to run 2 BOV?

I believe you are supposed to take the spring out and yes, the block off plate holds the diaphram in and also removes the vacuum line.

Correct, the block off plate is used when you want to have an aftermarket BOV, like Synapse (which has been the #1 seller)

kling1022

so does anyone know if this works ok? i mean i thought it hurt performance if you ran an aftermarket BOV?

PimpLay2

WRONG

you dont need a block off plate for MY SETUP

maybe for sychronic setup

i use a bov

pm me

i run one

i will make a vid soon,,,,, i use turbo xs BOV

kling1022

i would very much appreciate it. How do you do it and what intercooler piping are you using pimplay?

PimpLay2

i use synapseturbo intercooler piping with the turbo xs flange on it

pm me i will tell you its pointless telling you on a thread because people will still tell you that you need a block off plate so pm me so you can have it saved on what to do


i want to make a video now but my car has up to like 6 inches of snow around it lol

08BlackSS/TC

If there wasn't any use for a block off plate, then it wouldn't have been produced.

PimpLay2

yes it might be the CLEAN look of having no cord run

but it certainly isnt a MUST

sheldon729

Hahn is the best for everything but the intercooler piping i would go with synapse but everything esle hahn FTW

Ok so you did not read my original question saying I would disconnect it from the vacuum source then

I will have to agree with PimpLay2 on this one because a block off plate is just a plate to increase spring pressure just like I was going to do with the washers and all I should need to do is cap off the nipple which in reality should not have any air coming from it seeing how it is on the inside of the diaphragm and does not receive air from the intake.



Read this post from dejon about it he suggests hooking the recirculating valve to a boost source in front of the throttle body to keep it closed under boost which is a good Idea but I wonder if i can keep it shut just on spring pressure alone without spending the rediculous 45$ for the hahn logo on a part of my engine no one will ever see.

it looks flat to me how can a flat piece hold in a diaphragm without a spring or do they leave the giant hole in the charge pipping by removing the diaphragm too.

08BlackSS/TC

Yeah and in post #10 he states the best way to do it is a block off plate.
