    LS3, E38 ecu , whipple install.

    2015 SS camaro, LS3 , whipple with stock 4.0 pulley, LT headers no cats, LS9 cam. What would be the general consensus on manifold volume settings for this setup to aid in transients?

    All help appreciated.

    10.5-11.5 (depending on how big the “snout” is) be a solid foundation

    I assume that is for the 2.9L front feed Whipple? Haven’t played around with this setting for awhile but did so with the rear feed 2.3L Whipple. Stock truck manifold was 14,000, but so were some stock cals for factory blown cars. I lowered it some but can’t remember where I ended up.

    Ben Charles, stock ls3 is 9540cm so your saying about 10-20 percent more over stock as a
    trial to start out, up to 10,500-11,500 cm?
