Well buy a camera.

 

after i sell my car

 

Which one? (waiting on vids of OP z.. )

 

the one thats competing with yours in the for sale forum

 

Stock they trap right around 150mph so around 800whp sounds about right.. and thats stock!

 

theres a quick little video of first second and 3rd...on 4psi going through the stock exhaust.

 

No its the same..maybe the cars are a little different..it fits nice now though. Anyways, we both have a problem that needs to be addressed. The bovs are being shipped with a spring thats too heavy for our cars and we are both getting compressor surge bad. We need to drop down to the 11psi spring or 9 so it will fully open.I hear it on your videos too. They ship with 12psi springs which you need to pull more than -22hg in order to open it. My car pullls around 18-19hg which says it needs either the 11 or 9 spring to fully open.

 

Is Intense going to send you the other spring??

 

I see you beat the EVO!!!!

 

Mark Ive finally found a lil time and been examining your video more closely ....now that finally the baby is sleep and not at work with bad speakers lol.
I think you are hearing flutter... not surge.
Surge is way louder, major compressor surge sounds alot different, its like a duck going crazy while accelerating. Its the spring fluttering, the piston in the bov flutters when you decelerate.

How many things things tee'd off your BOV, it needs to have its on vacumm line.


Whatch this: http://video.google.com/videosearch?...8&sa=N&tab=wv#

see how that its under boost and no vacuum? Compressor surge that would kill a turbo would happen under load not under vacuum, and if i recall i think you are mostly pushing half throttle.

I really believe its flutter what you hear... its not a big deal and that the reasons the tials flutter like that is because they simply dont leak. TIal BOVs are known for pretty much "killing" surge...that same flutter you hear it with an hks too.

This is the better example i found of what real surge is:

this is flutter

not necesarly normal but its fine. Pretty much the majority of the positive pressure is released. it might shorten the life of the turbo by 2% over 20-30k miles

IMO i would rather have a BOV that isnt weak at all because chances are it could leak especially at higher boost...

You come form a supra background, I know a couple 18 year old supras have been running HKS SSQVs that "fake surge" for 10 years and put 50,000 miles on it and the stock turbos dont have shaft play
I would wait till you funnly tune your car and run consistantly at full throttle before you jump onto something

 

good luck figuring out your problem. any pics of how you notched the IC to fit the bumper brace?

 

no its surge. I can feel it come out of the compressor with my hand..also it keeps blowing the nylon screen off the front of the opening. That thing should never come off unless air was coming out the other way. Also, the tial 50mm on my trans am would open up wide as soon as you started the car...this car doesnt pull enough vacuum to open the 12 and 11psi springs..tial actually rates different springs for different hgs..my car pulls 17.9 at idle which is set for the 9lbs spring.....the BOV is on its own vacuum line.

 

No, I didn't even contact them about the issue. Im going to try the spring first and if it works then ill call em and let them know.

 

I think my car pulls over 20 in/mg. You might have a vaccum leak.

 

Marc, did you ask Tial about this?

 

at a stop at idle mine pulls 17.9. While driving it will pull over 22 momentarily.

 

They said if you don't request a specific spring they send you an 11psi spring. They said you have to have to check your vacuum parked at idle and they gave me a few numbers and mine fell into the 9psi spring range. The BOV should be wide open at idle. The vacuum is what compresses the spring holding it open and as soon as you apply throttle the spring closes and the boost+spring pressure is what holds it closed under accel.

 

at a stop at idle i am at 20 ... 22 when i'm in gear and off the gas

 

yeah its strange..if im rolling at idle it sits at 20-22 as soon as I come to a stop it goes down to 17.9

 

I had some idle issues with my Turboxs BOV, but we stacked some "fine tuning" washers in it, and car idles perfect now
