    Default Adding Turbo Hiss

    I actually Like the Turbo Hiss at Idle and want to make it Louder.

    I saw the Thread a few Down, and saw how to get Rid of the Hiss, so I just basically Reversed everything.

    In the Tables (B2210-B2215) I made the RPM 300-800 & mm3 0-20 Values 100%.

    Then in Tables (B2222-B2224) again, I made the RPM 300-800 & mm3 0-20 Values 100%.

    Is this all I need to do?

    And this won't Hurt anything right?

    Make sure you have your maximum tables to 100% or they will limit how much the vanes will go

    Thats pretty much all you gotta do

    No damage other than longer cool down times for the EGTs

    Im almost positive your engine will never cool down..... Good luck getting it below 300* after a run. Matter of fact it will stay warm for a LONG TIME with the vanes closed that much.

    With that much backpressure, im sure it will also ramp up the fuel rate due to the engine being sluggish so the exhaust fumes will probably burn your eyes.

    Give it a try and tell us what happens.



    I just brought my percentages down to 40% I think---actually it might have been 20% to help it cool off quicker when im ready to shut it down.

    EGT's im speaking of


    As for the 06lbz--I believe the maximum percentage is 85% if I remember correctly.

    It does take a long time to cool off but it will get to 300. fumes are not that bad. I had my vanes set at 99 at one point.

    20% is a good place to have them i think. it sounds good and it cools down faster

    So you upped yours to 20 rather than the 10% you recommended in another Thread?

    No I didnt, I said that '20% is a good place to have them I think'. I still have them at 10%. I tested them at 20 and i liked the way it sounded, plus it will cool off pretty fast since they are still pretty open.

    I suppose this would be no worse than leaving he exhaust brake on at idle....

    One positive note about THAT much vane closure would be instant warm up time.

    Wouldnt want that in the summer but to each his own I suppose.
