    Will a Hellcat Throttle body work on a 13 Challenger?

    wondering if anyone has attempted this or should we just get a BBK throttle body?

    Can't see why not, I often put them on the blown (non hellcat) hemis.

    Is there any special tuning for them if you wouldn't mind sharing or just take the values form a hellcat tune?

    I used factory hellcat numbers in the three throttle body airflow tables and worked well, I would start there.

    So here's the kicker....

    if you use the adapters from MMX, they are sold to neck down to the opening you have on the intake. The factory 6.4L plastic manifold I believe has a 85mm opening stock, it can be bored out to accommodate a 90mm opening. But if you leave it stock bore, and buy the 85mm adapter, then the 92mm flow rates in the hellcat tune isn't going to work spot on, itll be close though.

    I used the hellcat TB on a 6.1L manifold which has a similar opening and it worked OK, i did tweak the numbers a little as it was a little lazy (made numbers smaller so ECU cracked the throttle open faster to achieve same airflow).

    Thanks guys this car was a 5.7 liter M6 now has a crate 440 with LT headers and has an Edelbrock intake manifold 92 mm bore, and a mild cam.

    I have the throttle body installed and I am struggling with getting it to Idle stalls out anything below 1300 rpm, with the hell cat air flow tables or stock.
