Thread: 3.4L Whipple Cobra Sleeper

  1. Default 3.4L Whipple Cobra Sleeper

    Here is a few pics of a little 3.4 L whipple cobra we finished up about a week ago, We built it and Eric brooks tuned it when he was up here a few weeks back.

    I will post the dyno runs asap.

    Mods consisted of the following:

    Whipple 3.4
    Full Return Fuel system with a billet fore hat and twin walbro pumps -8an Feed line, -6an Return line
    Fore Billet fuel rails/ 60 lb injectors
    Billetflow Diff brace
    Full Length MM Subframe Connectors
    ARH 1 7/8 Longtube headers with 3" X pipe
    Mcleod RXT Twin Disk clutch
    Evans Cooling mod
    Afco Twin pass Heat Exchanger


    707 rwhp and looks like stock!

    We did ARH Longtube headers and a mcleod RXT Twin disk clutch first and got some miles on those before the car got the big blower on.







    Then it was time for the BIG girl! 18 psi on pump gas and 21 on C16







    Then the final install pictures, Sleepy stock lookin vert

    With the mods you have I would do a 2.9 or 3.4 with these mods, a RXT twin disc and 26 spline upgrade.

    Like Younggun said, a Whipple requires the same mods as a Kenne Bell - upgraded fuel system, a decent clutch and a new tune.

    Also if you want to get the most out of the bigger whipples I would recommend doing Long tubes as well. after 600 RWHP the stock manifold start to become a restriction.
