    • Who needs a Trackhawk? Whipple 2.9 liter supercharged Jeep Grand Cherokee SRT makes 644 rwhp

      It is no secret the new Jeep Grand Cherokee Trackhawk is disappointing with its test numbers. For whatever reason the 707 horsepower supercharged Hellcat 6.2 liter V8 is just not strutting its stuff in the Grand Cherokee chassis. Maybe a standard Cherokee SRT with a blower is a better way to go?


      It certainly is a cheaper way to go. We're talking roughly a $20k difference although considering the Trackhawk is brand new it will be harder to deal on and dealers are more than willing to negotiate on the SRT.

      Throw on a 2.9 liter Whipple and you have Hellcat power at a discount:


      The main difference would be the Hellcat has room to grow and the forged internals can take quite a bit of abuse compared to the higher compression naturally aspirated 6.4 liter Hemi the SRT starts with.

      Keep in mind a 2.9 liter Whipple has considerable headroom and is a bigger blower than the Hellcat 2.4 liter.

      However you look at it justifying the Trackhawk's price is tough at the moment.

        Not bad at all. I’m really excited for the audi RSQ5 coming out. That thing will be the king of the Hill for SUV performance.

        I'm looking forward to it too but doubt it will offer any real towing or utility.
