    TiAL 50mm BOV is supposed to be closed at idle!

    I know you didnt put a bov on a diesel trunk, thats probably why they didnt work properly! Way to go!!!

    I run twin Tials on my supra, and they respond much faster than the tial in this video….. Maybe they were running a restricted vac. source, or the incorrect spring to make thier product look better?

    its not about boost, its about vacuum pressure at idle.

    is that a fucking for truck?

    Another SYNAPSE nutswinger…i dont understand how after the 8 or 9 years tial has had the 50mm BOV on the market there have been no problems. But as soon as Synapse comes out with their BOV they make false videos of the Tial making their BOV look like it works better… TIAL>SYNAPSE

    Its funny to see people flame others for not knowing why its setup the way it is. A stiffer spring would create more surge. We changed from a 9psi to 7psi spring. It helped alot! Does it really matter if its open at idle when you are trying to reduce surge? So you would rather have it closed at idle and have more surge? What is your real point in using a bov in the first place? The main point is that on throttle, the tial closes and it would blow off quicker using a lighter spring.

    Tial tells everyone to run the softer spring. Is it only me that sees that Tial valve floating like a turd at idle?

    SYNAPSE IS FULL OF SHIT.

    “dipshit.. wrong spring for the vacuum being used. BOV opens at idle, FTL.

    guys like this make the TiAL look bad.”

    is that a turbo?? or just a blow off valve making sound

    Great vid and information, have you had it on the dyno. I would love to know what it is making to the wheels. Great job.

    The synapse sounds like when i snort oxycontin through a mcdonalds straw

  18. Konna on August 10th, 2008
