Flatplane vs Crossplane V8 Engines - Which Is Best?

  • Flatplane vs Crossplane V8 engines. Foreign vs. domestic. What is a flatplane crankshaft? What is a crossplane crankshaft? These engines get their names from the design of the crankshaft, and have key distinct differences. Flatplane engines have the primary forces balanced out, so the crankshaft can be light and fast revving. Crossplane V8 engines have the secondary forces balanced out, making them very smooth with the addition of counterweights to balance out the primary forces.

      And this is an old video. Just keep digging through the videos. I've subbed and I've dug and backtracked. Believe it or not I have a leatherback automotive mechanics manual (not a fix it book but an engineering and MECHANICS of automotives book) and it goes into detail about crossplane and floatplane cranks. It was printed in 1946.

    @rdsimmonds 3 роки тому +5

    A couple of issues I have, cross plane cranks don't necessarily need a larger crankcase when comparing the 2 crank styles with identical strokes. Also, there are center weighted cross plane cranks that are lighter than normal production cranks, and still maintain the vibration reduction. The only real benefits to the flat plane are the points you made for exhaust scavenging, as well as intake wave tuning. But contrary to popular belief, they do not inherently rev any significant amount higher than what can be done with a cross plane.

    Those are known as 90 degree and 180 degree cranks. I always default to original nomenclature whenever possible. "Tri-Wye" headers (different for each bank) eliminate the uneven scavenging with a 90 degree crank. They work great (and sound great) on my 440 Cubic Inch Chrysler big block.

  • @superchief15
    @superchief15 4 роки тому +3

    The flat plane crank is just the beginning of engineering this type of engine. The cam shafts has to match the new firing order,the Ignition has to do the same. The introduction of balance shafts can mitigate the size of the crank throws. The only benefit is higher RPMs and possibly Horse Power. The thing to remember is if you change one thing like the crank or value timing. You have to change everything! That is why forced induction is so popular. Just need a step down in compression and either plumping the exhaust for a turbo or plumbing the intake flow for a super charger!

Allison engineers had to deal with THIRD-ORDER harmonics because of long shafts used to drive the overhead cams and engine accessories mounted on top of the engine. Included is an exploded view drawing showing the various imbalances and their vectors.

    For people curious, yes - most road cars have crossplane crankshafts. The typical burbly, low-frequency roaring V8 noise is produced by the firing order of crossplane crankshafts. This type of crankshaft was designed by cadillac and hence why it is refferred to as the "american" V8.
    All ferrari V8's have used flatplane crankshafts in the past 50 or so years. Lotus esprit v8 and McLaren V8's are the only other road cars I can think of that have used flatplane cranks.

    the first diagram of a crankshaft is a bit skewed.. is that on purpose? The one on the right looks more traditional.. ?

    I'm here because of the crossplane crank on the r1. More advantages vs a flatplane on a bike. Looks like opposite for car world

    A video on exhaust scavenging or just how headers work and why they are shaped the way they are would be great! I agree with a few other people though, the illustration in this video is hard to understand.
