RIPP says 320 HP at 7 psi. 3 more pounds got you another 100 hp?
What supporting mods have you done? Injectors?
The 7lb tune they provide is pretty mild
With a hotter tune you can get 330-340 on 6-7lbs
I have a stage 2 kit ..which is basically srt sized piping/intercooler and 900cc injectors
With the larger intercooler and piping it increased boost to 10lbs..because of the larger intercooler and injectors it allows you to increase fuel and timing
The stock 3.6l fuel system falls flat on its face at the 410-420 hp mark ..which in this vehicle is ~530-540hp at the crank
That's why I stopped at that mark..and I'm pretty sure that's why ripp stopped at 400hp also..they like to be conservative and safe with their systems..I've since built a new motor (completely forged custom blower specific block/cams and heads)and built a new fuel system with 1/2" lines and a return system to allow for constant fuel flow..the stock system has no return line
I also have an srt in tank pump with a fuel pump booster and custom fuel rails that allow for more than double the stock fuel delivery
I'm hoping this should give me the fuel I need up top ..which is where it was lacking before
If you look at Ripp's videos you'll see them cranking out 400whp on the stage 1 kit in a Grand Cherokee
They're also getting 448whp on the stage 1 kit in the charger ...so I'm guessing they're running hotter tunes now because that means they took a 300hp. 3.6l and are getting over 500hp at the crank on 7-8lbs
If you haven't seen this then you need to
