    Frp has a Tomahawk 2.0 cam with 111 LSA . For a street car this should be all one would need and make great power everywhere. I think 108-110 would be the best LSA for these cars with 108 preferred. A cam with 230-235@50 intake duration would be all you would ever need. You could run a single patteen on these cars as they have decent exhaust flow. Of course a cam with that much duration and that tight lss would require flycut or aftermarket pistons. The 6.4 with upgraded springs is more than capable of 7000+rpm which is where the 230+ cams will shine and the tight LSA would keep your bottom end. The idle would be radical and a good tuner mandatory. I will be building my Hellcat next year. Most likely will spec a custom cam though the FRP offerings are getting pretty close. A cam with 230in 242exh and 108lsa would be very nice indeed. Boost in the 20-23lb range with my Kong ported 4.5 Whipple.💪 It will be 400+ci. Im factory blower and 17lbs on pump gas now with a few gallons of e85 and some boostane for safety. I plan to run E85 when built and leaded e85 when i need to push the car harder

      Hemi's do not work well with tight lobes, and generally anything that adds Overlap with restrictive street exhausts is going to result in a loss down low. Nobody who's familiar with the Gen 3 hemi is going to put a Single Pattern, Long Duration Cam with a tight lobes in it. It's all centered around keeping overlap to a minimum, because they don't respond well to it.Going from a 224* at .050" to 234*@.050 would require closing the intake valve 5* later (low-mid loss) and double the overlap from 5 to 10 (which with street exhaust's will result in more power lost). Which is why once you get to the 220-228 @ .050" Intake/230-238ish at .050" exhaust range and 112-114 Lobe sep, you see greatly diminishing returns on both the 5.7 and 6.1/6.4. 2 of the 3 Guys that have gone 10's N/A on 5.7 Hemis in trucks, guess what the cam specs were? 218/228 at .050" on a 112 LSA. Jay Greene's cams have even more split, 15* or more. One last Caveat - FRP Ryan's Cams, even those that have tightish lobes, aren't a 111 LSA, they're a 111ICL. By advancing the cam timing and not the lobe, he gets the low-mid increase from the earlier intake valve close, but doesn't need to add in the duration and overlap that you'd get from moving just the intake lobe, which would cause the power loss experienced in this video. Check out SPDC's hemi cam testing - they tested a 108LSA, and a 112 matched it down low and made more in the midrange and up top as well. Notice how once they get to the high 21X range on the intake and high 22X range on the exhaust, there's really not much more gains. czcams.com/video/RxSQDvgqeAY/video.html

  • @mikew6135
    @mikew6135 Před 10 měsíci

    Obviously no need for any more than stage 1 on the stock motor. One of the MAJOR issues is LSA. Usually the smaller cams have tighter LSA which makes more TQ and average HP. Just facts. Somehow in all our modern wisdom; we think that adding duration along with a widened LSA is the way to go. It's not! Run a tighter LSA and moderate duration. This will provide what the engine wants and not what you want. On a Hellcat you could grind a cam with factory numbers except for big tightening of the LSA and make more power everywhere. Most likely beating aftermarket wide LSA cams in average power. You could also keep your VVT while increasing power everywhere. On a side note . You CAN get a lopey idle with the smaller can and tighter LSA

  • @morrischoo9960
    @morrischoo9960 Před rokem

    The variable cam timing retards the cam as revs increase. Idk, but let's say it varies by 8 degrees. Would maybe start out with a 4 degree advance on the cam optimized for torque in the middle of the power band. And at half rpm or 3050, would be at zero degrees. Then drop a degree every 760 rpm increase. It's best to pick a cam that gives the best average horsepower from basically 1000 rpm to redline. And the flattest torque curve. A dialed in setup is what is needed. No one component will ever really improve and engine like the 6.4 without supporting changes. Best post I've seen thus far . Eliminating the non wrenching boy racers opinions is a refreshing thing. Noise and lope are not necessarily faster. Efficiency always is.

    The stock bottom end can handle the the higher rpm range with upgraded valve train. The 6.4’s do not have a long enough stroke to cause issues. Sorry, but the video is a waste if you are not maxing the cams with their proper rpm range: also, having the cam specs will help a lot as well. Depending on how big the stage 3 is you could benefit from a shorter runner intake with a stall. Moreover, the video was done well.
