thanks for your help jimbo its better but not all the way fixed... im thinking im going to have to ditch the factory bpv and run an hks ssqv or something else. ive got little list of things to change today but stretching the spring on the bpv helped a BUNCH. it will get up to 0 release then cruise between 10-15 # of vacuum.

glad it helped man. with a custom setup like this you will spend some time working out the bugs and reconfiguring things. be patient, learn from it and have fun.

btw are you going to get the recirc kit for hks ssqv? if not and your going atmospheric, go with the tial bov.

IF i switch i will use the recirc so i dont have to change the intake relocate the maf and a bunch of other supporting mods to have the noise i really dont care that much for.

makes alot of sense, have been looking into one of these myself:

allready have a tial flange welded to my charge pipe so it makes it that much easier for m to switch to a recirc.......i also have my own tig welder

nice! kinda spendy though... cost more than my turbo did

yah but i can sell the old tial to offset some of the costs

ok im back again... i think stretching the spring helped but cant really tell. when i shift and accelerate again im almost instantly in boost. BUT, if i let off the throttle it will blow off the pressure then be just fine. the highway it seems better but im still hitting boost

slowswap

So when you accelerate you build boost? Welcome to how boost is made. Engine load goes up, so does boost.

im talking regular nice calm city grandma driving

I think you're expecting this to act to much like a larger turbo. When I had my CA18 240, it would spool very fast. Small taps of gas would bring it easily up to 5 psi.

Boost a video of what it's doing if possible.

i can text the vids. (cell phone) but on the highway it does alright just annoying it slowly creeping up then ssssfffeeewww. would lower compression pistons help?

slowswap

I think your missing the point.

Lowering compression would just lower power.

wouldnt that also slow down the air leaving? im also kicking around the idea of having the turbo ported... and putting the snorkel back on the intake and stretching the bpv spring more and moving my boost gauge source i think its reading wrong... it will say 5psi of boost but you cant feel any difference in it and n/a

slowswap

Boost gauge needs to reference off of the manifold.

Porting exhaust side would certainly slow down spool times. Not a huge amount but it could help.

BOV springs are designed to open after a certain amount of vacuum is reached to pull the diaphragm. Stretching could cause compressor surge. What BOV and spring are you running?

This would be easier if HPT supported you so we could see your logs. I think what your describing is a normal thing.

its the stock ko4 bpv and i know the lnf has a solonoid to control it...

slowswap

Might want to switch to an aftermarket.
