I raced a friend of mine last night with a 463whp fwd talon..and I gave him a spankin until the end of 4th and that was from a first gear roll.

anyways....haha i knew you would be doing your engine build earlier. Are you still doing the same parts you told me last time for your engine build?

funny part is..if you know how to use it..theres 0 lag..my car pulls INSTANTLY if you keep it in the right range..and on shifts theres also no noticable lag. And yes im still doing all the parts I said and the ones suggested by you and others.

my setup is pretty optimal and at 6 psi i am at 360 DD CATTED (400+ DJ)....you with a stock exhaust at 4 psi should not have more power than me, the physics don't favor your claim no matter the mass airflow of that turbo and exhaust restrition. just having a hard time believing you could overcome a car with that much power over you unless his power peaks exponentially

1. My car at 4psi will flow a good amount more air than your car at 4ps. Your cats are prolly just as restrictive(maybe a little less) than my exhaust. If I had the same exact setup as your car with the different turbo on the same PSI id easily make 20+whp more than you. PSI is a measurement of restriction...theres more room inside my turbo so at 4pounds per square inch theres more "inches" to fill up inside my turbo(even though its not actually full inches..but you get the point)
2. Why would I lie about beating that car? If you read it again I spanked him until 4th(I guess I should of finished the rest of the sentence)..he was pulling on my hard by the end of 4th. The only reason I beat him is because of traction issues...however I still beat him. I had enough of a lead in the first 2 gears for him not to be able to go ahead of me till the end of 4th.

i have set to see a member go over 50k boosted miles on the stock motor(vq)....
i think miaplaya is close to that at some point but not sure if he even has his Z anymore

To add..to the list of reasons why its important..is BRAKING. Everyone knows thats brakes work off of vacuum..and that vacuum lines turn into boost lines..(under boost)..well what happens is..since the BOV doesnt open right away on the heavier springs it holds the boost in the lines for a split second..anyone go from boost immediately to brakes??...they dont wory for a split second..they feel the same as when the car is off. If the gate FULLY opens right away like its supposed to..it lets all that boost out right away.

Ok I stepped down to the 7lbs spring.
11lbs: It fluttered badly and id get some surge, 0 brakes right off throttle
9lbs: Fluttered VERY little, very little surge but still there..also 0 brakes right off throttle but it would come back quicker
7lbs: No flutter at all, no surge, and I now have brakes right off of boost.
seems like even though im pullin vacuum in the 9lbs spring range..it still didn't completely fix the problem. You can tell if its working properly because the BOV is supposed to open up at startup and stay open during idle and snap shut when you touch the throttle. 11psi spring didnt move, the 9psi it moved slightly but didnt open and opened very slightly upon hitting/releasing the gas quickly and the 7 doesnt open up ALL the way but about 60% at idle and would open all the way upon hittin/releasing the gas quickly.

That brakes thing can be f-in scary, especially when your haulin ***. I'm used to road racing an all motor car, where everything is instantanious.. now I have to wait for the power AND the brakes...wtf lol
""And the excitement is over"" ha ha, thats going to happen with whatever you do.. its always fast for a week, then its like, this sucks, I need mo Powa!!
I knew 4lbs wasnt going to be enough for you, even for a little while... So whats it going to be up to by Friday?

FYI I contacted TiAL about this issue and they asked for my vacuum reading (inHG). I am going to stick a gauge on next week and use one of the accurate meters from work.
Idle vacuum is the yardstick for determining correct spring application.

Could the 11psi spring on our cars cause the diaphram on the Tial to jam open?
After about 400 miles on my BOV it no longer wants to close all the way and is leaking boost. You can hear a screeching sound everytime you let off the gas and im only getting 8psi out of the 9.2 im suppose to be getting and thats with the needle shaking like a crack fiend.
PL is shipping me another one, I would assume it has the same spring inside that came with my original one. These BOV's should come with the correct spring sizes regardless of if it is doing any damage to or not. For a kit with such high quality parts and high price tag cutting corners on something as tiny as that is ugh..retarded
