Turbosmart Dual Port BPV With Stillen Kit
Okay so today I took out the BPV included by stillen (plastic :icon14:) and put in the turbosmart dual port valve, and the extra soft blue spring that I've read people had to use. After a lot of slight turns dialing in the adjustment, i finally got a strong steady idle.
I noticed that when the valve wasn't quite dialed in, I wouldn't get the initial gauge sweep even though no SES lights or anything came on. I got it in a position now where it idles steady and gives me the gauge sweep and all. However, when I free rev the engine, it still bogs down just a little below idle. Since I'm so close I don't want to adjust it the wrong way and lose the steady idle lol. Should I tighten or loosen it bit by bit to get it right? Appreciate any possible help :tup: |
Gauge sweep? You don't have your bpv hooked to a gauge do you?

Not sure if this means anything even, just thought I'd mention |
Is it possible it requires a retune compared to the bosch style bpv? I feel like it's so close but I just can't get it perfect
gonna bring the laptop out tomorrow and grab a data log |
Just keep turning it 1/2 a turn more and more hard until it doesn't dip below idle. Its really easy to adjust. Do you have a a/f gauge?

Wanted to make sure that tighter was the way to go :tiphat: |
Cool. Yeah you are on the right path. You are probably 1/2 turn to 1 1/2 turns from being spot on from the sounds of it.
|
Think I got it ! Went just a bit less than 1 full turn (1/4 turn at a time) and now it seems to be holding steady after rev. Will take it for a datalog and test drive tomorrow :) Love the sound!
Guess I made the thread a bit hastily, was panicking when I couldn't get it after a few hours of tweaking lol. Thanks |
Good deal. Hey I was the same way when I first installed mine.

Do any of you have a pic of where this part goes when replacing the stillen unit? |
Your plastic bosch one is good up to 10psi. You can take the hoses off too but it will run like crap just like the turbosmart one would if you don't put the recirc hoses on.
Unless your going 11+ psi then it's just for sound. |
Yep exactly what Top said. Unless you plan on the impeller upgrade or smaller pulleys it is basically just for sound. It is definitely a higher quality part for sure though. Billet aluminum vs. plastic. Don't know how accurate or true this is but my former tuner told me that it also helps to release some heat from the intake tube that the supercharger produces. Sounds like it makes sense but don't know that it is proven.
|
Why would that make sense? Unless he is saying that since its metal it is acting as a heat sink and draws heat away from the pipe, the pipe that is in a very hot engine bay.
Doesn't make sense to me. |
I have one on my set up and Stillen actually had to retune the car with it till it worked properly with the Stillen SC
|
Yeah top he could have just been blowing smoke but it sounded legit at the time. Made it sound like opening the door to an oven would help the temperature of the air inside the intake decrease.
