The 18 up truck manifold has more torque below 4000 RPM and does not lose anything over 6500 RPM. It actually holds power longer than the 15-17 manifold.

Real world testing.
Interesting. You have any write-ups on this? First I've heard of it, and now you've got my interest. I also assume this doesn't apply to the Gen3's.

Not sure what would happen with the gen3. Probably gain some bottom and lose some top.

The only write up is my first post.

I wish it was spring because I think it will be quicker in the 1/4 mile at the same MPH or slightly better.

Because Ford changed the CMCV motors it needs a tune. Have to change the voltage and range parameters. What surprised me is it pulls to 6900 RPM. Maybe more, I need to do more testing.
Should have done before & after dyno tuning. Track testing is the next best thing though.

Wonder what it would be like with the vac solenoids locked out.

On the Truck/15-17 manifold it's all downhill after 6500 rpm. That's been proven to nauseum.

The '18+ truck manifold is a completely different animal. Like the difference in Mustang manifolds from Gen2 to Gen3.

I've wondered about this ever since I bought my '19 F150.

19 Ford F150 5.0L:

395 hp @5,750 rpm
400 lb.-ft. @4,500 rpm

Ford isn't gonna put a 7000 rpm intake manifold on a F150. The intake is optimised for towing.

I will say that Alex Flores tuned a 2020 F150 for E85 and claims to make it shift at 7500. In the video he said the motor pulls to there, so I would guess the intake is capable of breathing up high. I’ll see if I can dig the video up.

Trucks are meant to be low RPM with torque for towing. Mustangs are meant to be revved out. Why are you focusing on the low end again? I'd rather be shifting at 7600-7700 with an 18 manifold or a GT350. The 18 manifold has the midrange that the GT350 doesn't and is the best of both worlds. If your redline is higher than 8k, then you want a GT350 or Cobra Jet (with cams)
