    I wonder if you can get away with that if you change heads with the comedic gaskets ?

    Went to the chassis dyno friday. Thanks to Brandon front decorde automotive he got my carb issue figured out. Also made some good pulls. My 9.70 setup on 5 pounds peaking at 6 pounds of boost at 6000 rpm netted us 615 at the wheels. When we finished tuning we made a best of 691 horse and 594 torque at the wheels with a 22 percent slippage of the torque converter. That was a huge gain from carb tuning. Now it runs nice and safe and no more melting plugs. Or worse. We did make one pull at 12 pounds and it really like that. 807 and 691 at the wheels. Absolutely amazing with a broken converter. Do the math and it's over 1000 at flywheel.

    Fantastic!

    With 12 lbs of boost I MIGHT be making what you were with 6 lbs.

    It isn't what happens to you that matters most, but rather what you choose to do about it.

    How close is the adjustment of the Big Red BOV right out of the box ?

    Any tips on the adjustment ?

    I am using this TCI converter now on my boosted SBB as the last converter I had was also slipping big time like yours.

    I have broken too many off the shelf converters. this converter broke because the rear broke and locked up the trans and broke the main shaft of the trans. too much power at 4000 pounds of weight. Converter is at ultimate converter concepts and lenny is going to fix it up for the new power increase. When that converter was made we thought the motor only made 750 at flywheel. I guess we were a little bit off. lol

    Yes I agree custom converter is the way to go. I sent my TCI converter back to them and had them fine tune it for my combo, as I bought it for $300 used in the end I saved a bunch of money this way. My car is only 2980 pounds so that helps. Same deal with my car was not expected to see the power it is making.

    Called Procharger today to find out how to adjust the new Big Red BOV. He told me it is ready to use out of the box and no other advice (Hmmmm).

    I asked what he thought of changing from 1.60 ratio to 1.65 ratio (which I am doing) is going to do to the boost. Like I thought it is going to lower it overall.

    I was at 10.1 pounds of boost and want to stay there for many reasons.

    The next size smaller to the 4.00 inch pulley I have is a 3.850 inch pulley.




    And what ever you do, do not say you are working on a Big Block Buick as they will not know anything then !

    Have an Aeromotive with boost reference and wonder what would cause the fuel pressure not to adjust below 10 pounds ?

    Do you have a return line from the regulator? I learned the hard way that you need that.

    Return line smaller than feed line? Trash in the regular?

    After I took the regulator apart, I made a return to empty to a gas can and it does alright.
    So I guess it has something to do with the line going back to the tank.
