@@Andrewlytic Im currently running the hellcat throttle body ported to 95mm with the 95mm to 90mm adapter plate. The MMX ported 6.4 intake manifold (the opening is 90mm to match the throttle body adapter plate) The SRV controller by ZAuto to control the runners of the intake. OEM actuator. This is by far the best intake setup for a NA hemi, no doubt in my mind. Before the manifold and throttle body the cars dyno thing from the SRT pages said a peak HP of 424 on a 32° day. After the manifold and throttle body that number was up to 466 on a 32° day. Just over 40hp from just that is pretty dam good IMO. (If that dyno is somewhat accurate)

that open air box is prone to heat soak even with that heat shield. Better option is the hellcat airbox which is fully closed and pulls ambient air directly from outside the car through the inlet tube.
@seanem72612 жыл бұрын
Actually the jlt box is better than the hellcat box , first the filter is bigger . Then the air is pulled from 3 places not just 2 , which would be the front of the car like the hellcat box , the top from the vent on the hood and the bottom from the wheel well. And last the position of the intake air temperature sensor is positioned inside the box which gives a cooler reading than the stock sensor position. So as far as heat soak , the jlt set doesn’t heat soak , it’s within 4-5 degrees of ambient temp when running on a roval road course track on a 105* degree day . It’s a way better design than the hellcat air box , Both in functionality and design .
@M5skee_joezay2 жыл бұрын
@@seanem7261 lets put it this way, the hellcat airbox was engineered to feed a 2.4 liter supercharger and a 92mm throttle body. . My 0-100 got 2 tenths of a second faster consistently without a tune. The shops tune those intakes with the hood open which is unrealistic since they are removing all the heat soak you would get in real life, blowing up the numbers of that JLT. I used to have a mopar intake which was same shit as JLT and it got heavy heat soak. Lastly, that JLT doesnt have an inlet tube feeding it air directly from the front of the headlight..

Hey Bee! What you are describing is something called "Drivetrain Loss". Think of it this way: It takes energy to move the torque converter, transmission, drive shaft, rear end, wheels/tires etc. All of those parts have mass that requires energy from the engine to move. When you measure the output at the engine, then measure the output at the wheels, that difference is the drivetrain loss. That loss varies greatly from vehicle to vehicle!
