No questions here... more of a "Here's me with a grin" post.

So I experienced PTB for the first time this morning after installing an AGP w/g. I haven't yet tweeked with the tension. I assume it's gonna need it since she spikes at 16, holds 14, but I know the AGP is supposed to hold 15...which still isn't much off I guess. I drove around for a bit on the streets and everything was fine...actually much more than fine. The I hit the freeway and that's where I noticed the PTB. Annoying, but not as much as I expected. Aside from that, I've got the biggest grin from ear to ear that you've ever seen. It's a big difference over the stock w/g, at least to me. But I've dealt with boost leaks and such lately so maybe it's only because I had become used to lower than stock psi. Either way, my car and I have just become reaquainted and I love her even more. I think I'll treat her to a bubble bath today and maybe some flowers.

Sorry to bore everyone, I'm just a little bit excited with the results and had to tell someone.

 

PTB? Part Throttle Boost?

Why would having boost earlier - at part throttle - be annoying?[&:]
I'm just curious. [8D]

 

Yeah...once you get used to driving the car w/ ptb it is not that bad. It is definitly worth it.

 

I cannot comprehend why part throttle boost would be bad...[&:]

 

It is annoying because the car runs very lean during ptb...as I have watched with a wideband. PTB over probaly 5 psi is bad on the car. With PTB it can boost to 15 psi w/ 14.xx afr's. So you either need to floor it or keep it under 5 psi at least.

 

they have that on the stg2 and 3s and if anything there running rich. i like my stg2 because ptb alows me to stay in gears longer with out down shifting like going up he moutains to work everyday i never have to get out of 5th gear it just pulls at part throttle.just my 2cents.

 

PTB and the flutter are evil.

The compressor tries to spool up way faster than it should, and it stalls itself. Thus wearing down the longevity of your turbo. So that flutter sound your getting at PTB, is HORRID for the car. You have to re-learn how to drive the car in order to avoid it.

 

i didnt mean that high i only get like 5 to 7 psi. 15 is crazy for part throttlle boost.

 

Sorry for my Ignorance im still learning about Turbos

1) what is PTB? How do you get it and how do you avoid it?
2) what exactly does an upgraded BoV / or Wastegate do for you?

 

part throttle boost where you get max boost or close to it at part throttlle which is bad. bovs im not to familiar with how one works better then another.
