Why a baffled oil pan with windage tray and not a dry sump system?

    "The engine uses a new oil pan with extra baffles and a windage tray to keep the oil where it belongs under hard acceleration ."

    I wonder why they did not use a dry sump system in the Hellcat other than the obvious reason: cost. Seems like they went all out with forged everything DLC coating etc. So just wondering why they didnt add this too...

    I do not seem to read or hear any problems with oil starvation in these engines so maybe the dry sump systems are not that big a deal....

    Anyone know the answer?

    Not a high rpm motor and to much cost I would guess. They also thought the motor didn't need anymore power. Ha

    That's exactly it - dry sumps at / below 6500 rpm would be a complete waste. We don't even use a dry sump on a BB Mopar till well after that...even with a oiling system designed in the late 50's (albeit industry leading / well ahead of its time)

    Okay I see the reasoning without the higher rpm you have less oil getting caught up in a vortex/spinning around etc. but why would the Corvette c6 ZR1 use a dry sump system - their rpm is 6500....?

    I guess their engineers saw the need based on the engine design etc. while ours did not....?

    Thanks

    The C6 Zr1 is a solid build ..I have owned 2 Corvettes and never had a problem.....the Z06 on the other hand with valve train issues and the newer corvettes...are problematic. However, I was on their forum for years and years and no problems at all with the Zr1 LS9 engine. It is solid as the LS3 is...no supercharger issues either ...:confused:

    Lol - I was kidding

    The ZR1 was 1 of the best GM made. Sustained high rpm as a goal would mean the dry sump would be the way to go

    Overkill in a Hellcat aimed more for short bursts IMO

    The Corvette has it due to the high lateral G's it can pull and it allows the engine to be mounted lower so it can fit under that low hood line.

    Thought about the G's being tracked oriented but Didn't think of that which is probably the main driver. You win

    We raced dirt track for years with a SB Chevy spinning 7500, and wet sump. We never had an oil problem.
    It is not in every new C7 Vette, only the Z51's./ZO-6's
    Its also not in the new ZL1 camaro

    Corvettes use it because they are made for road racing too. They can turn and pull serious g forces. Not knocking our cars, they handle well for what they are, but they are not in that category. Also the vettes are lower and may need the ground clearance. Oil in the pan isn't really getting thrown around in all directions with our cars. We simply don't need it. Add that to the cost and that's why we don't have it.

    Exactly. Dry sump reduces the height of the engine and allows it to be mounted lower and reduce the CG. My Triumph motorcycle is dry sump because it is 2300 cc and dry sump is necessary to make the engine short enough to fit in a bike.
